Equity instruments and their features
  • Depositary receipt value

    Level I

    Receipt value = shares per receipt × home price ÷ exchange rate

    exchange rate
    units of home currency per unit of the receipt's currency

    Arbitrage keeps the receipt's market price close to this figure.

    Related tool A1 Returns & Corporate Actions

  • Conversion value of a preferred share

    Level I

    Conversion value = conversion ratio × common share price

    conversion ratio
    common shares received per preferred share

    Holders convert when this beats the call price or the value of staying preferred.

Share classes, jurisdictions and voting
  • Voting share with dual classes

    Level I

    Voting share = votes held ÷ total votes across all classes

    A small economic stake can hold most of the votes, so compare the two.

    Related tool A1 Returns & Corporate Actions

  • Cumulative voting

    Level I

    Total votes = shares × seats up for election

    All the votes can go on one candidate, which helps a minority holder win a seat.

Issuance, trading and liquidity
  • Free float

    Level I

    Free float = shares issued − treasury shares − closely held shares

    Closely held shares
    stakes held by insiders, founders or governments

    Tool A1 works from shares outstanding: free float = N × (1 − insider share).

    Used in A1 Returns & Corporate Actions

  • Daily turnover of float

    Level I

    Daily turnover = average daily volume ÷ free float

    Measure against the float, not all shares, because locked-up shares can't trade.

    Used in A1 Returns & Corporate Actions

  • Days to build a position

    Level I

    Days = position ÷ (ADV × participation)

    ADV
    average daily volume
    participation
    share of daily volume you can take

    Dividing by full daily volume ignores the limit on how much of the market you can be.

    Used in A1 Returns & Corporate Actions

  • Average daily volume

    Level I

    ADV = total volume ÷ trading days

    ADV
    average daily volume

    Use trading days in the period, not calendar days.

    Related tool A1 Returns & Corporate Actions

  • Annual share turnover

    Level I

    Turnover = annual volume ÷ shares

    State the base: a question may set turnover on the free float, not on all shares.

    Related tool A1 Returns & Corporate Actions

  • Percentage bid-ask spread

    Level I

    Percentage spread = (ask − bid) ÷ [(ask + bid) ÷ 2]

    ask
    lowest price a seller quotes
    bid
    highest price a buyer quotes

    Measure against the midpoint. Half the spread is the distance from the midpoint to one side.

    Related tool A1 Returns & Corporate Actions

  • Average execution price

    Level I

    Average price = Σ(shares at each price × that price) ÷ shares bought

    An order larger than the depth at the best quote walks up the book and pays more on average.

    Related tool A1 Returns & Corporate Actions

  • Gross proceeds of an offering

    Level I

    Gross proceeds = new shares × offer price

    Existing shares sold by a founder raise no capital for the firm.

    Related tool A1 Returns & Corporate Actions

Types of equity index
  • Float-adjusted index weight

    Level I

    Weight_i = (cap_i × float_i) ÷ Σ(cap × float)

    cap
    market cap of a constituent
    float
    share of its shares that trade freely

    A large firm with a small float can carry less weight than a smaller firm that trades freely.

    Related tool A1 Returns & Corporate Actions

Price and total return
  • Price return

    Level I

    Price return = (P₁ − P₀) ÷ P₀

    P₀
    price at the start
    P₁
    price at the end

    It counts the price change only, so it understates what a holder of a dividend payer earned.

    Used in A1 Returns & Corporate Actions

  • Total return, one period

    Level I

    Total return = (P₁ − P₀ + D) ÷ P₀

    P₀
    price at the start
    P₁
    price at the end
    D
    dividends paid in the period

    A price fall can still give a positive total return if the dividend is larger than the fall.

    Related tool A1 Returns & Corporate Actions

  • Total return, linked over periods

    Level I

    R = (1 + r₁) × (1 + r₂) × … × (1 + r_T) − 1

    R
    return over the whole holding period
    r_t
    total return in period t
    T
    number of periods

    Multiply, never add. Tool A1 links monthly returns, which assumes dividends are reinvested each month.

    Used in A1 Returns & Corporate Actions

  • Total return with a dividend reinvested

    Level I

    Total return = (1 + D ÷ P_d) × P₁ ÷ P₀ − 1

    D
    dividend per share
    P_d
    price at which the dividend buys more shares
    P₀
    price at the start
    P₁
    price at the end

    The dividend buys extra shares, and those shares also earn the later price move.

    Related tool A1 Returns & Corporate Actions

  • Return from dividends

    Level I

    Return from dividends = total return − price return

    Over several years this includes the return earned on reinvested dividends, so it is more than the sum of the yields.

    Used in A1 Returns & Corporate Actions

  • Annualized return

    Level I

    Annualized return = (1 + R)^(1 ÷ n) − 1

    R
    return over the whole period
    n
    number of years

    Dividing R by n ignores compounding and overstates the yearly rate of a gain.

    Used in A1 Returns & Corporate Actions

Dividends, repurchases and splits
  • Split or reverse split

    Level I

    Shares after = N × k; price, EPS and BVPS after = each one before ÷ k

    N
    shares outstanding
    k
    new shares per old share; below 1 for a reverse split
    BVPS
    book value per share

    Market cap doesn't change. To measure a return across a split, adjust the old price by k as well.

    Used in A1 Returns & Corporate Actions

  • Stock dividend

    Level I

    Shares after = N × (1 + s); price, EPS and BVPS after = each one before ÷ (1 + s)

    N
    shares outstanding
    s
    stock dividend as a share of existing shares

    It works like a small split: more shares, the same company, the same market cap.

    Used in A1 Returns & Corporate Actions

  • Shares left after a buyback

    Level I
    Level II

    Shares after = N − A ÷ P

    N
    shares outstanding
    A
    amount spent on the buyback
    P
    price paid per share

    The higher the price paid, the fewer shares the same money retires.

    Used in A1 Returns & Corporate Actions

  • EPS after a buyback from cash

    Level I
    Level II

    EPS after = NI ÷ (N − A ÷ P)

    NI
    net income
    N
    shares outstanding
    A
    amount spent on the buyback
    P
    price paid per share

    Net income is held flat, so EPS rises. A rise in EPS alone doesn't mean value was created.

    Used in A1 Returns & Corporate Actions

  • Book value per share after a buyback

    Level I
    Level II

    BVPS after = (E − A) ÷ (N − A ÷ P)

    E
    book equity before the buyback
    N
    shares outstanding
    A
    amount spent on the buyback
    P
    price paid per share

    BVPS rises if the shares are bought below book value per share, and falls if bought above it.

    Used in A1 Returns & Corporate Actions

  • Ex-dividend date

    Level I

    Ex-date = record date − (settlement days − 1) business days

    Settlement days
    business days from trade to settlement

    The last day to buy and still get the dividend is the business day before the ex-date. Tool A1 skips weekends, not holidays.

    Used in A1 Returns & Corporate Actions

  • Expected price on the ex-date

    Level I

    Ex-date price = P − D

    P
    price before the ex-date
    D
    dividend per share

    The fall in market cap equals the cash paid out, so holders are no better or worse off.

Price, value and mispricing
  • Estimated value per share from payouts

    Level I
    Level II

    V₀ = [Σ payout_t ÷ (1 + r)^t + TV ÷ (1 + r)^n] ÷ N

    payout_t
    cash the forecast can pay shareholders in year t
    TV
    next year's payout after the forecast ÷ (r − g)
    r
    required return on equity
    n
    number of years
    N
    shares outstanding

    This is the case's estimate used by tools A2 and B1. It is only as good as the assumptions in the case.

    Used in A2 Value Measures

  • Gap between price and value

    Level I
    Level II

    Gap = P ÷ V − 1

    P
    price
    V
    estimated value

    Above zero, the price is above the estimate. It's a gap against your assumptions, not proof of mispricing.

    Used in A2 Value Measures

  • Gap as a percent of price

    Level I

    Gap = (V − P) ÷ P

    P
    price
    V
    estimated value

    The same gap is a different percent of the value than of the price, so always state the base.

    Related tool A2 Value Measures

  • Perceived gap, split

    Level II

    Estimate − price = (true value − price) + (estimate − true value)

    Part of any gap is the analyst's own error, which can be larger than the real mispricing.

    Related tool A2 Value Measures

  • Yearly return to a target price

    Level I

    Annual return = (target ÷ price)^(1 ÷ n) − 1

    n
    number of years

    The same rise earns less per year the longer the price takes to get there.

    Related tool A2 Value Measures

Book value, market cap and enterprise value
  • Book value of equity

    Level I

    Book value = assets − liabilities

    It records past accounting, so it can sit far from what the assets would fetch today.

    Related tool A2 Value Measures

  • Book value per share

    Level I
    Level II

    BVPS = common equity ÷ shares outstanding

    common equity
    total equity less any preferred stock
    BVPS
    book value per share

    Take preferred stock out first: its holders have a prior claim.

    Used in A2 Value Measures

  • Market capitalization

    Level I

    Market cap = price × shares outstanding

    shares outstanding
    shares issued less treasury shares

    Treasury shares don't count. Market cap is the market's opinion at a moment, not a value estimate.

    Used in A2 Value Measures

  • Net debt

    Level I
    Level II

    Net debt = debt − cash

    A negative figure means net cash. Short-term investments count as cash.

    Used in A2 Value Measures

  • Enterprise value

    Level I
    Level II

    EV = market cap + debt + preferred − cash

    EV
    enterprise value
    preferred
    preferred stock

    Add minority interest too if the firm has it. EV isn't used for banks or insurers, whose debt is part of operations.

    Used in A2 Value Measures

CAPM and the market model
  • CAPM

    Level I
    Level II

    r = r_f + β × ERP

    r
    required return on equity
    r_f
    risk-free rate
    β
    beta, the share's sensitivity to the market
    ERP
    equity risk premium

    A share plotting above this line has an expected return higher than the risk requires.

    Used in A3 Required Return Builder

  • Equity risk premium from the market return

    Level I

    ERP = E(R_m) − r_f

    E(R_m)
    expected return on the market
    r_f
    risk-free rate
    ERP
    equity risk premium

    If a question gives the market return, take off the risk-free rate before multiplying by beta.

    Related tool A3 Required Return Builder

  • Market model

    Level I

    R_i − r_f = α + β × (R_m − r_f) + ε

    R_i
    the share's return
    R_m
    the market's return
    r_f
    risk-free rate
    α
    intercept
    β
    beta, the share's sensitivity to the market
    ε
    residual, with an expected value of zero

    Tool A3 fits this on 120 months of excess returns. It describes the past; CAPM gives the forward-looking rate.

    Used in A3 Required Return Builder

  • Beta from covariance

    Level I

    β = Cov(R_i, R_m) ÷ σ_m²

    Cov(R_i, R_m)
    covariance of the share with the market
    σ_m²
    variance of the market

    Divide by the variance, not the standard deviation: square σ_m first.

    Related tool A3 Required Return Builder

  • Beta from correlation

    Level I

    β = ρ × σ_i ÷ σ_m

    ρ
    correlation of the share with the market
    σ_i
    standard deviation of the share
    σ_m
    standard deviation of the market

    A volatile share can have a low beta if little of its movement goes with the market.

    Related tool A3 Required Return Builder

  • Adjusted beta

    Level I

    β_adj = ⅔ × β + ⅓

    β
    beta, the share's sensitivity to the market

    It pulls a measured beta toward 1, because betas tend to drift that way over time.

    Used in A3 Required Return Builder

Arbitrage pricing and multi-factor models
  • Multi-factor required return

    Level I
    Level II

    r = r_f + b₁ × premium₁ + b₂ × premium₂ + … + b_k × premium_k

    r_f
    risk-free rate
    b_k
    the share's sensitivity to factor k
    premium_k
    the return premium on factor k

    A negative loading lowers the return, as a growth share's value loading does.

    Related tool A3 Required Return Builder

  • CAPM with size and value factors

    Level I
    Level II

    r = r_f + β × ERP + b_size × size premium + b_value × value premium

    r_f
    risk-free rate
    β
    beta, the share's sensitivity to the market
    ERP
    equity risk premium
    b_size
    the share's size loading
    b_value
    the share's value loading

    Each premium is multiplied by its loading first. This is the multi-factor line in tool A3.

Equity risk premium and required return methods
  • Historical equity risk premium

    Level II

    ERP = average equity return − average government bond return

    ERP
    equity risk premium

    Strip out any one-way rise in the market P/E over the sample: it won't repeat.

    Related tool A3 Required Return Builder

  • Gordon growth equity risk premium

    Level II

    ERP = D₁ ÷ P + g − y

    D₁
    index dividends expected next year
    P
    index level
    g
    constant long-run growth rate
    y
    long-term government bond yield

    Grow the dividend first: a question that gives the dividend just paid needs D₀ × (1 + g).

    Related tool A3 Required Return Builder

  • Supply-side equity risk premium

    Level II

    ERP = [(1 + i) × (1 + rEg) × (1 + ΔPE) − 1] + Y − y

    i
    expected inflation
    rEg
    expected real EPS growth
    ΔPE
    expected yearly change in the market P/E
    Y
    expected income return
    y
    long-term government bond yield

    Don't leave out the P/E change, and take off the bond yield: without it you have the equity return.

    Related tool A3 Required Return Builder

  • Bond yield plus risk premium

    Level II

    r = yield on the firm's long-term debt + risk premium

    r
    required return on equity

    A sense check when beta is unreliable: equity ranks behind debt, so r should sit above the bond yield.

Cost of debt and WACC
  • After-tax cost of debt

    Level I
    Level II

    After-tax cost of debt = r_d × (1 − t)

    r_d
    pre-tax cost of debt
    t
    tax rate

    Interest is tax deductible, which makes debt cheaper than its stated rate.

    Used in A3 Required Return Builder

  • WACC

    Level I
    Level II

    WACC = [E × r + D × r_d × (1 − t)] ÷ (E + D)

    E
    market value of equity
    D
    net debt
    r
    required return on equity
    r_d
    pre-tax cost of debt
    t
    tax rate

    Use market weights, not book. Tool A3 floors net debt at zero. Tool C3 keeps it negative, so a net cash firm's WACC comes out above r.

    Used in C3 DCF Lab

  • WACC from a debt weight

    Level II

    WACC = w_d × r_d × (1 − t) + (1 − w_d) × r_e

    w_d
    debt as a share of capital
    r_d
    pre-tax cost of debt
    t
    tax rate
    r_e
    required return on equity

    A private firm has no market weights, so use a target or peer weight, or iterate from the value.

    Used in E1 Private Company Valuation

  • WACC year by year

    Level II

    WACC_t = [E_t × r + D_t × r_d × (1 − t)] ÷ (E_t + D_t)

    E_t
    equity value at the start of year t
    D_t
    net debt at the start of year t
    r
    required return on equity
    r_d
    pre-tax cost of debt
    t
    tax rate

    This is what makes FCFF agree with FCFE when leverage changes. One constant WACC won't.

Industry classification, size and growth
  • Market size and share

    Level I

    Market size = units × average price; share = firm revenue ÷ market size

    A change in share is a difference in percentage points, not a percent change.

    Related tool B1 Industry Analyzer

  • Concentration ratio

    Level I

    Top-n share = revenue of the n largest firms ÷ total revenue

    n
    number of largest firms counted

    It ignores how shares are spread inside the top group. In tool B1 the base is the peers' revenue, not the whole market.

    Used in B1 Industry Analyzer

  • Herfindahl index

    Level I

    HHI = Σ(share in percent)²

    HHI
    Herfindahl-Hirschman index

    Shares go in as whole percents. Two markets with the same four-firm share can have different indexes.

    Related tool B1 Industry Analyzer

  • Compound annual growth rate

    Level I

    CAGR = (ending ÷ beginning)^(1 ÷ years) − 1

    years
    periods between the two figures, one less than the years listed

    Five reported years span four periods of growth, so count the gaps, not the years.

    Used in B2 Company Analyzer

Five Forces and PESTLE
  • Pretax return on invested capital

    Level I

    Pretax ROIC = operating margin × revenue ÷ invested capital

    Margins alone mislead when industries need very different amounts of capital.

    Related tool B1 Industry Analyzer

Revenue, margins and capital needs
  • Revenue growth

    Level I

    Revenue growth = revenue ÷ last year's revenue − 1

    Revenue is volume × price, so growth rates combine as (1 + a) × (1 + b) − 1, not a + b.

    Used in B2 Company Analyzer

  • Gross margin

    Level I

    Gross margin = (revenue − cost of goods) ÷ revenue

    It stops before operating expenses, so a good gross margin can hide heavy overheads.

    Used in B2 Company Analyzer

  • EBIT margin

    Level I

    EBIT margin = EBIT ÷ revenue

    EBIT
    earnings before interest and tax

    Compare this across firms with different debt, because interest and tax come later.

    Used in B2 Company Analyzer

  • Net margin

    Level I
    Level II

    Net margin = net income ÷ revenue

    The first DuPont factor. Debt and tax both affect it.

    Used in B2 Company Analyzer

  • Degree of operating leverage

    Level I

    DOL = contribution ÷ operating profit

    DOL
    percent change in operating profit per percent change in sales
    contribution
    sales less variable costs

    High fixed costs raise DOL, so a small rise in sales lifts profit by much more.

    Related tool B2 Company Analyzer

  • Days of receivables

    Level I

    Days of receivables = receivables ÷ (revenue ÷ 365)

    Rising days can mean looser credit terms, which absorbs cash even when sales are growing.

    Used in B2 Company Analyzer

  • Days of inventory

    Level I

    Days of inventory = inventory ÷ (cost of goods ÷ 365)

    Use cost of goods, not revenue, because inventory is carried at cost.

    Used in B2 Company Analyzer

  • Days of payables

    Level I

    Days of payables = payables ÷ (cost of goods ÷ 365)

    Longer days free up cash, but paying past the agreed terms can't last.

    Used in B2 Company Analyzer

  • Cash conversion cycle

    Level I

    Cycle = days of inventory + days of receivables − days of payables

    Payables come off, because suppliers fund that part of the cycle.

    Used in B2 Company Analyzer

  • Capex to revenue

    Level I

    Capex to revenue = capex ÷ revenue

    A firm that must reinvest more for the same growth is worth less.

    Used in B2 Company Analyzer

  • Capex to depreciation

    Level I

    Capex to depreciation = capex ÷ depreciation

    Above 1 the asset base is growing; below 1 for long, it may be wearing out.

Ratio analysis and DuPont
  • Return on equity

    Level I
    Level II

    ROE = net income ÷ equity

    Used in B2 Company Analyzer

  • Return on assets

    Level I
    Level II

    ROA = net income ÷ total assets

    It equals net margin × asset turnover: the return before leverage.

    Used in B2 Company Analyzer

  • Asset turnover

    Level I
    Level II

    Asset turnover = revenue ÷ total assets

    Revenue earned on each unit of assets.

    Used in B2 Company Analyzer

  • Financial leverage

    Level I
    Level II

    Leverage = total assets ÷ equity

    More leverage lifts ROE, but shareholders carry more risk for it.

    Used in B2 Company Analyzer

  • DuPont, three parts

    Level I
    Level II

    ROE = net margin × asset turnover × leverage

    Compare each factor across years to see which one moved ROE.

    Used in B2 Company Analyzer

  • DuPont, five parts

    Level I

    ROE = tax burden × interest burden × EBIT margin × asset turnover × leverage

    It only splits net margin into three, so the answer is the same ROE.

    Used in B2 Company Analyzer

  • Tax burden

    Level I

    Tax burden = net income ÷ pretax income

    A higher figure means less tax. It equals 1 − t.

    Used in B2 Company Analyzer

  • Interest burden

    Level I

    Interest burden = pretax income ÷ EBIT

    A higher figure means less interest. Net interest income can push it above 1.

    Used in B2 Company Analyzer

  • Debt to equity

    Level I

    Debt to equity = debt ÷ equity

    Check whether lease liabilities are in debt before comparing firms.

    Used in B2 Company Analyzer

  • Debt to capital

    Level I

    Debt to capital = debt ÷ (debt + equity)

    Unlike debt to equity, this can't go above 100% while equity is positive.

    Related tool B2 Company Analyzer

  • EBITDA

    Level I
    Level II

    EBITDA = EBIT + depreciation

    EBITDA
    earnings before interest, tax, depreciation and amortization

    It ignores the capital spending that depreciation stands for, so it isn't free cash flow.

    Used in B2 Company Analyzer

  • Net debt to EBITDA

    Level I

    Net debt to EBITDA = net debt ÷ EBITDA

    Years of EBITDA needed to repay net debt. Negative means more cash than debt.

    Used in B2 Company Analyzer

  • Interest cover

    Level I

    Interest cover = EBIT ÷ net interest expense

    It has no meaning when the firm earns more interest than it pays.

    Used in B2 Company Analyzer

Financial statement forecasting
  • Forecast revenue

    Level I

    Revenue_t = revenue_(t−1) × (1 + growth)

    Tool B3 fades growth toward the long-run rate over the forecast.

    Used in B3 Forecast Builder

  • Real growth

    Level I
    Level II

    Real growth = (1 + nominal) ÷ (1 + inflation) − 1

    Taking inflation off the nominal rate is only an approximation.

    Used in B3 Forecast Builder

  • Forecast working capital balances

    Level I
    Level II

    Receivables = revenue × days ÷ 365; inventory and payables = cost of goods × days ÷ 365

  • Value from a peer price multiple

    Level I
    Level II

    Value per share = adjusted multiple × company's per-share figure

    per-share figure
    EPS, book value per share or sales per share

    The multiple and the figure must be on the same basis. A peer P/S ignores a lower margin.

  • Value from a peer EV multiple

    Level I
    Level II

    Value per share = (adjusted EV/EBITDA × EBITDA − net debt) ÷ shares

    An EV multiple gives firm value, so take off net debt before dividing by shares.

  • Value from a peer dividend yield

    Level II

    Value per share = dividend per share ÷ adjusted yield

    Yield runs the other way: a higher yield means a lower price.

  • Premium or discount to peers

    Level I
    Level II

    Premium = company multiple ÷ peer multiple − 1

    For a yield, flip it to peer yield ÷ company yield − 1, so the premium is still measured on price.

  • Adjusted peer multiple

    Level II

    Adjusted multiple = benchmark × (1 − risk discount) × (1 + growth premium)

    benchmark

  • Cost of equity at a new debt weight

    Level II

    r_e after = [(1 − w_d) × r_e + w_d × r_d − w_d after × r_d] ÷ (1 − w_d after)

    r_e
    cost of equity before
    w_d
    debt weight before
    w_d after
    debt weight after
    r_d
    pre-tax cost of debt

    The pre-tax blend is held still, so more debt moves risk onto equity without changing the firm's own risk.

  • Constant payout dividend

    Level II

    Target dividend = EPS × target payout

    Dividends paid on this rule swing with earnings, so few firms follow it exactly.

  • Expected dividend under a target payout

    Level II

    D₁ = D₀ + (EPS × target payout − D₀) × adjustment factor

    D₀
    dividend just paid
    adjustment factor
    1 ÷ years taken to close the gap

    Only part of the gap to target closes each year, which keeps dividends smooth.

  • Dividend coverage on net income

    Level II

    Coverage = net income ÷ dividends

    Dividends are paid in cash, so earnings cover alone doesn't show a dividend is safe.

  • Dividend coverage on free cash flow

    Level II

    Coverage = (CFO − capex) ÷ dividends

    CFO
    cash from operations

    Below 1 with rising debt is a classic sign the dividend is being borrowed.

Comparing and reconciling models
  • Gap between models

    Level I
    Level II

    Gap = model value − anchor value

    anchor value
    the payout value of the forecast at the required return

    Models on the same forecast and rate should agree, so a gap points to a difference in assumptions.
