Financial Analysis

Reading the P&L, Balance Sheet, and Cash Flow Statement.

WACC

Weighted Average Cost of Capital. The average interest rate a company pays to finance itself.

Formula
(Eq% * CostEq) + (Debt% * CostDebt * (1-Tax))
The hurdle rate. If a project returns less than WACC, it destroys value.

EBITDA

Earnings Before Interest, Taxes, Depreciation, and Amortization. A proxy for raw operating cash flow.

Useful for comparing companies with different debt/tax structures, but ignores the cost of assets (Capex).

Free Cash Flow (FCF)

The actual cash a company generates after spending money to maintain its asset base.

Formula
OperatingCashFlow - CapitalExpenditures
Cash is king. Dividends and buybacks are paid from FCF, not 'Net Income'.

EPS (Earnings Per Share)

The portion of a company's profit allocated to each share.

Formula
NetIncome / SharesOutstanding
The primary driver of stock prices in the long run.

Gross Margin

The percentage of revenue retained after direct costs of goods sold (COGS).

Formula
(Revenue - COGS) / Revenue
High gross margins (e.g., Software > 80%) indicate a strong competitive moat.

Working Capital

A measure of a company's short-term liquidity.

Formula
CurrentAssets - CurrentLiabilities
Positive is good. Negative implies the company may struggle to pay bills soon.

Valuation Multiples

Metrics to determine if a stock is cheap or expensive.

P/E Ratio

Price-to-Earnings. How much you pay for $1 of earnings.

Formula
SharePrice / EPS
High P/E (>30) implies high growth expectations. Low P/E (<10) implies value or decline.

PEG Ratio

P/E Ratio adjusted for Growth. Helps find 'Growth at a Reasonable Price' (GARP).

Formula
PE / AnnualGrowthRate
PEG < 1 is undervalued. PEG > 2 is expensive.

EV / EBITDA

The Enterprise Value divided by EBITDA. The standard valuation metric for M&A.

Better than P/E for comparing companies with different levels of debt.

Price to Book (P/B)

Market value vs Net Asset Value.

Formula
Price / BookValuePerShare
Crucial for Banks and Real Estate. Irrelevant for Tech (which has few tangible assets).

Portfolio Theory

Risk, return, and diversification concepts.

Sharpe Ratio

Measures risk-adjusted performance.

Formula
(Return - RiskFree) / Volatility
A ratio > 1.0 is good. It exposes funds that generate returns simply by taking excess risk.

Alpha

The excess return of an investment relative to the return of a benchmark index.

If the market did 10% and you did 12%, your Alpha is +2%.

Beta

A measure of volatility relative to the market.

Beta = 1.0 (Moves with market). Beta = 1.5 (50% more volatile). Beta < 1 (Defensive/Stable).

Correlation

How two assets move together (-1 to +1).

Diversification only works if assets are not perfectly correlated. If everything falls together, you aren't diversified.

Trading Mechanics

How markets function, order types, and liquidity.

Short Selling

Borrowing shares to sell them now, hoping to buy them back cheaper later.

Profit from price drops. Infinite risk (price can go up forever).

Bid-Ask Spread

The difference between the highest price a buyer offers (Bid) and lowest price a seller accepts (Ask).

A wide spread means low liquidity. You lose money instantly upon buying.

Limit Order vs Market Order

Market Order: Buy immediately at any price. Limit Order: Buy only at a specific price or better.

Always use Limit Orders in volatile markets to avoid bad fills.

Margin

Borrowed money used to purchase securities.

Magnifies gains and losses. Can lead to a 'Margin Call' where you are forced to sell assets.

Derivatives

Options, Futures, and hedging instruments.

Call Option

A contract giving the right (but not obligation) to BUY a stock at a set price.

A bullish bet. You want the price to skyrocket.

Put Option

A contract giving the right (but not obligation) to SELL a stock at a set price.

A bearish bet or insurance. You profit if the price crashes.

Strike Price

The pre-agreed price at which the option can be exercised.

If stock price is above Strike, a Call option is 'In The Money'.

Macroeconomics

The big picture forces moving markets.

Inflation (CPI)

The rate at which prices rise. Erodes the purchasing power of cash.

The enemy of bonds. Stocks can sometimes pass on inflation costs; bonds cannot.

Fed Funds Rate

The base interest rate set by the Central Bank.

The 'Gravity' of finance. When rates rise, asset prices (Stocks, Real Estate) generally fall.

Yield Curve

A line plotting yields of bonds having equal credit quality but differing maturity dates.

Inverted Yield Curve (Short term rates > Long term rates) has predicted every recession since 1950.

Quantitative Easing (QE)

Central banks printing money to buy assets, injecting liquidity into the economy.

Generally boosts asset prices but risks inflation.

GDP (Gross Domestic Product)

The total value of goods and services produced in a country over a period.

Two consecutive quarters of negative GDP growth typically defines a recession.

Unemployment Rate

The percentage of the labor force that is jobless and actively seeking work.

A lagging indicator—often peaks after a recession has already begun.

PMI (Purchasing Managers Index)

A survey-based indicator of manufacturing and services sector health.

Above 50 = expansion. Below 50 = contraction. A leading indicator.

Valuation Methods

Techniques for determining intrinsic value.

DCF (Discounted Cash Flow)

Valuation method that projects future cash flows and discounts them to present value.

Formula
Value = Σ(FCF / (1+r)^n) + Terminal Value
The gold standard for intrinsic valuation. Highly sensitive to growth and discount rate assumptions.

Terminal Value

The value of a business beyond the explicit forecast period in a DCF.

Formula
FCF * (1+g) / (r-g) [Gordon Growth]
Often 60-80% of total DCF value. Small changes in assumptions dramatically affect results.

Comparable Company Analysis

Valuing a company by comparing it to similar publicly traded companies.

Quick and market-based, but assumes comparables are fairly valued.

Precedent Transactions

Valuing a company based on what similar companies sold for in M&A deals.

Includes control premiums, so typically higher than trading multiples.

Sum of the Parts (SOTP)

Valuing each business segment separately and adding them together.

Used for conglomerates. Often reveals 'hidden value' in underappreciated divisions.

NAV (Net Asset Value)

The total value of assets minus liabilities, divided by shares outstanding.

Formula
(Total Assets - Total Liabilities) / Shares
Primary valuation for REITs, closed-end funds, and asset-heavy businesses.

Return & Risk Metrics

Measuring performance and risk-adjusted returns.

CAGR (Compound Annual Growth Rate)

The smoothed annualized growth rate over a period.

Formula
(Ending Value / Beginning Value)^(1/Years) - 1
Useful for comparing growth rates across different time periods.

Sortino Ratio

Like Sharpe Ratio but only penalizes downside volatility.

Formula
(Return - RiskFree) / Downside Deviation
Better for asymmetric returns since it ignores upside volatility.

Maximum Drawdown

The largest peak-to-trough decline in portfolio value.

Measures worst-case loss. A 50% drawdown requires 100% gain to recover.

Treynor Ratio

Risk-adjusted return using beta instead of total volatility.

Formula
(Return - RiskFree) / Beta
Best for evaluating diversified portfolios where unsystematic risk is minimized.

Information Ratio

Active return divided by tracking error vs benchmark.

Formula
(Portfolio Return - Benchmark Return) / Tracking Error
Measures consistency of outperformance. Higher is better.

Value at Risk (VaR)

The maximum loss expected over a given time period at a confidence level.

e.g., '95% VaR of $1M' means 95% confident losses won't exceed $1M.

Investment Strategies

Approaches to building and managing portfolios.

Dollar Cost Averaging (DCA)

Investing a fixed amount at regular intervals regardless of price.

Reduces timing risk and emotional decision-making. Best for long-term investors.

Value Investing

Buying stocks trading below their intrinsic value with a margin of safety.

Pioneered by Graham & Dodd. Requires patience and contrarian thinking.

Growth Investing

Buying stocks with above-average growth potential, often at premium valuations.

Focuses on revenue/earnings growth rather than current valuation.

Momentum Investing

Buying assets that have been rising, selling those falling.

Based on the tendency of trends to persist. Requires disciplined exits.

Index Investing

Passive strategy that tracks a market index like the S&P 500.

Low cost, tax efficient. Outperforms most active managers over time.

Factor Investing

Targeting specific drivers of return: value, momentum, quality, size, low volatility.

Systematic approach to capturing risk premiums across asset classes.

Fixed Income

Bonds, yields, and credit markets.

Coupon Rate

The annual interest payment as a percentage of the bond's face value.

A 5% coupon on a $1,000 bond pays $50 per year.

Yield to Maturity (YTM)

The total return expected if the bond is held until maturity.

Accounts for coupon payments, current price, and time to maturity.

Duration

A measure of a bond's sensitivity to interest rate changes.

A duration of 5 means a 1% rate rise causes ~5% price drop.

Credit Spread

The yield difference between a corporate bond and a government bond of same maturity.

Wider spreads indicate higher perceived default risk.

Investment Grade

Bonds rated BBB-/Baa3 or higher by major rating agencies.

Lower risk, lower yield. Many institutions can only hold investment grade.

High Yield (Junk Bonds)

Bonds rated below investment grade (BB+/Ba1 or lower).

Higher default risk but significantly higher yields. Behave more like equities.
