SEC Filings & Reports
Understanding SEC filings is crucial for any serious investor. These mandatory documents contain the most reliable information about public companies.
10-K (Annual Report)
What it is: A comprehensive annual report that public companies must file with the SEC within 60-90 days of their fiscal year end.
Why it matters: The 10-K is the most complete picture of a company's financial health. Unlike glossy annual reports sent to shareholders, the 10-K contains audited financials and detailed risk disclosures that companies are legally required to provide.
Key sections to read:
- Item 1A (Risk Factors): What could go wrong with the business
- Item 7 (MD&A): Management's explanation of financial results
- Item 8 (Financial Statements): The audited numbers
Pro tip: Use AI tools like MoneySense AI to get instant summaries of lengthy 10-K filings and identify the most important sections.

10-Q (Quarterly Report)
What it is: A quarterly financial report filed with the SEC for the first three quarters of a company's fiscal year.
Why it matters: 10-Qs provide more frequent updates than annual reports, helping you track a company's performance throughout the year. Note that these financials are *unaudited*, unlike the 10-K.
Key difference from 10-K: Less detailed, unaudited, and covers only three months instead of twelve.
8-K (Current Report)
What it is: A report filed when a significant event occurs that shareholders need to know about immediately.
Why it matters: 8-Ks often contain market-moving news like CEO departures, acquisitions, bankruptcy filings, or major contract wins. Companies must file within 4 business days of most events.
Common 8-K triggers:
- Executive changes
- Mergers and acquisitions
- Bankruptcy or receivership
- Delisting from an exchange
- Material cybersecurity incidents
S-1 (IPO Filing)
What it is: The registration statement a company files with the SEC before going public through an Initial Public Offering (IPO).
Why it matters: The S-1 is your best source of information about a company before it starts trading. It includes business model details, financial history, risk factors, and how the company plans to use IPO proceeds.
Proxy Statement (DEF 14A)
What it is: A document filed before shareholder meetings that contains information about matters to be voted on.
Why it matters: Proxy statements reveal executive compensation, board member backgrounds, and potential conflicts of interest—information you won't find in other filings.
MD&A (Management Discussion & Analysis)
What it is: A section in 10-K and 10-Q filings where management explains the company's financial results in their own words.
Why it matters: The MD&A provides context that raw numbers can't. Management explains *why* revenue increased or decreased, what challenges they faced, and what they expect going forward.
EDGAR
What it is: The SEC's Electronic Data Gathering, Analysis, and Retrieval system—the database where all public company filings are stored.
Why it matters: EDGAR is free and publicly accessible at sec.gov. Every SEC filing from every public U.S. company is available here.
Earnings & Financial Statements
Earnings reports and financial statements tell you how a company is actually performing. Here are the key terms you need to understand.
Earnings Report
What it is: A quarterly announcement of a company's financial performance, including revenue, profit, and earnings per share.
Why it matters: Earnings reports often cause significant stock price movements. The market reacts not just to the numbers, but to how those numbers compare to expectations.

EPS (Earnings Per Share)
What it is: A company's profit divided by the number of outstanding shares.
Formula:
EPS = Net Income ÷ Shares OutstandingWhy it matters: EPS tells you how much profit a company generates for each share of stock. Higher EPS generally indicates better profitability.
Example: If a company earns $100 million in profit and has 50 million shares outstanding, its EPS is $2.00.
Revenue (Top Line)
What it is: The total amount of money a company brings in from selling its products or services, before any expenses are deducted.
Why it matters: Revenue growth shows whether a company is expanding its business. A company can cut costs to boost profits temporarily, but sustained growth requires revenue growth.
Net Income (Bottom Line)
What it is: A company's total profit after all expenses, taxes, and costs have been deducted from revenue.
Why it matters: Net income shows what's actually left over for shareholders. It's the "bottom line" because it appears at the bottom of the income statement.
Gross Margin
What it is: The percentage of revenue left after subtracting the direct cost of goods sold.
Formula:
Gross Margin = (Revenue - Cost of Goods Sold) ÷ Revenue × 100Why it matters: Gross margin shows how efficiently a company produces its products or services. Higher margins mean more profit potential.
Operating Margin
What it is: The percentage of revenue left after subtracting operating expenses (salaries, rent, marketing, etc.).
Formula:
Operating Margin = Operating Income ÷ Revenue × 100Why it matters: Operating margin shows how efficiently a company runs its core business operations, excluding interest and taxes.
EBITDA
What it is: Earnings Before Interest, Taxes, Depreciation, and Amortization.
Why it matters: EBITDA is used to compare profitability between companies by removing the effects of financing decisions and accounting practices. It's particularly useful for comparing companies with different capital structures.
Caution: Warren Buffett famously dislikes EBITDA because it ignores real costs. Depreciation represents real wear and tear on assets that eventually need replacement.
Free Cash Flow
What it is: The cash a company generates after accounting for capital expenditures needed to maintain or grow its business.
Formula:
Free Cash Flow = Operating Cash Flow - Capital ExpendituresWhy it matters: Free cash flow shows how much actual cash a company can return to shareholders through dividends or buybacks. Unlike earnings, cash flow is harder to manipulate through accounting.
Guidance (Forward Guidance)
What it is: A company's forecast of its own future financial performance, usually provided during earnings calls.
Why it matters: Guidance often moves stock prices more than actual results. If a company beats earnings but lowers guidance, the stock often falls. If it misses but raises guidance, the stock often rises.
Earnings Beat/Miss
What it is: When a company's reported earnings are higher (beat) or lower (miss) than analyst expectations.
Why it matters: Stocks often move based on whether results beat or miss expectations, not on the absolute numbers. A company can report record profits and still see its stock fall if it missed expectations.
Consensus Estimate
What it is: The average of all analyst predictions for a company's earnings or revenue.
Why it matters: The consensus estimate sets the bar that companies are measured against. Beating consensus is generally positive; missing it is generally negative.
Earnings Call
What it is: A conference call held after earnings are released where management discusses results and answers analyst questions.
Why it matters: Earnings calls provide context and color that press releases don't. Management tone, forward-looking comments, and responses to tough questions can be more valuable than the numbers themselves.
Pro tip: MoneySense AI can analyze earnings call transcripts to extract key insights, sentiment, and red flags automatically.
Whisper Number
What it is: An unofficial, unpublished earnings expectation that circulates among traders and investors.
Why it matters: Sometimes the whisper number—not the official consensus—is what the market is really expecting. A company might beat the consensus but still disappoint if it misses the whisper number.
Stock Market Basics
These fundamental terms form the foundation of investing knowledge.
Stock (Equity/Share)
What it is: A unit of ownership in a company. When you buy a stock, you become a partial owner of that business.
Why it matters: Stocks have historically been one of the best ways to build long-term wealth, though they come with short-term volatility risk.
Market Capitalization (Market Cap)
What it is: The total value of a company's outstanding shares.
Formula:
Market Cap = Share Price × Shares OutstandingCategories:
- Large Cap: $10 billion+
- Mid Cap: $2 billion - $10 billion
- Small Cap: $300 million - $2 billion
- Micro Cap: Under $300 million
Why it matters: Market cap tells you the size of a company and helps compare companies in the same industry.
Float
What it is: The number of shares available for public trading, excluding shares held by insiders, employees, and major shareholders.
Why it matters: Stocks with small floats can be more volatile because there are fewer shares available to trade.
Volume
What it is: The number of shares traded during a given period.
Why it matters: High volume indicates strong interest in a stock. Unusual volume can signal that something significant is happening.
Liquidity
What it is: How easily an asset can be bought or sold without significantly affecting its price.
Why it matters: Highly liquid stocks are easier to trade at fair prices. Illiquid stocks can have wide bid-ask spreads and unpredictable price movements.
Dividend
What it is: A payment made by a company to its shareholders, typically from profits.
Why it matters: Dividends provide income to investors and signal that a company is profitable and confident about its future.
Dividend Yield
What it is: The annual dividend payment divided by the stock price, expressed as a percentage.
Formula:
Dividend Yield = Annual Dividend ÷ Stock Price × 100Example: A stock trading at $100 that pays $4 annually has a 4% dividend yield.
Stock Split
What it is: When a company divides its existing shares into multiple shares, reducing the price per share proportionally.
Example: In a 2-for-1 split, someone with 100 shares at $200 each would have 200 shares at $100 each. The total value stays the same.
Why it matters: Splits don't change a company's value, but they can make shares more accessible to smaller investors and increase liquidity.
Blue Chip
What it is: A large, well-established company with a history of stable earnings and often dividend payments.
Examples: Apple, Microsoft, Johnson & Johnson, Coca-Cola
Why it matters: Blue chips are generally considered safer investments, though they may offer lower growth potential than smaller companies.
Valuation Metrics
These metrics help you determine whether a stock is overpriced, underpriced, or fairly valued.
P/E Ratio (Price-to-Earnings)
What it is: A stock's price divided by its earnings per share.
Formula:
P/E Ratio = Stock Price ÷ EPSExample: A stock trading at $50 with EPS of $2.50 has a P/E of 20.
Why it matters: The P/E ratio tells you how much investors are willing to pay for each dollar of earnings. A higher P/E suggests investors expect higher growth.
Benchmarks:
- S&P 500 average: ~20-25
- Growth stocks: Often 30+
- Value stocks: Often under 15
Forward P/E
What it is: The P/E ratio calculated using estimated future earnings instead of past earnings.
Why it matters: Forward P/E reflects expectations about future performance, which is what ultimately drives stock prices.
PEG Ratio (Price/Earnings to Growth)
What it is: The P/E ratio divided by the expected earnings growth rate.
Formula:
PEG = P/E Ratio ÷ Annual EPS Growth RateWhy it matters: The PEG ratio helps determine if a high P/E is justified by growth. A PEG under 1 is often considered undervalued; over 2 may be overvalued.
P/S Ratio (Price-to-Sales)
What it is: A stock's market cap divided by its revenue.
Formula:
P/S Ratio = Market Cap ÷ Annual RevenueWhy it matters: P/S is useful for valuing companies that aren't yet profitable, like many tech startups. It shows how much investors are paying for each dollar of sales.
P/B Ratio (Price-to-Book)
What it is: A stock's price divided by its book value (assets minus liabilities) per share.
Why it matters: P/B helps identify companies trading below the value of their assets. A P/B under 1 means the stock is trading below its book value.
Enterprise Value (EV)
What it is: A measure of a company's total value that includes market cap, debt, and subtracts cash.
Formula:
EV = Market Cap + Total Debt - CashWhy it matters: EV represents the theoretical takeover price of a company. It's more comprehensive than market cap because it accounts for debt obligations.
EV/EBITDA
What it is: Enterprise value divided by EBITDA.
Why it matters: EV/EBITDA is used to compare valuations across companies with different capital structures. Lower ratios may indicate undervaluation.
DCF (Discounted Cash Flow)
What it is: A valuation method that estimates the present value of future cash flows.
Why it matters: DCF attempts to determine what a stock is actually worth based on projected future performance, rather than relative metrics like P/E.
Trading Terms
Understanding these terms helps you navigate buying and selling securities.
Bid Price
What it is: The highest price a buyer is currently willing to pay for a stock.
Ask Price (Offer)
What it is: The lowest price a seller is currently willing to accept for a stock.
Bid-Ask Spread
What it is: The difference between the bid and ask prices.
Why it matters: A narrow spread indicates a liquid market; a wide spread suggests lower liquidity and higher trading costs.
Market Order
What it is: An order to buy or sell immediately at the best available current price.
Pros: Guaranteed execution
Cons: No price guarantee; you might pay more or receive less than expected
Limit Order
What it is: An order to buy or sell only at a specified price or better.
Pros: Price control
Cons: No guarantee the order will be filled
Stop-Loss Order
What it is: An order to sell a stock if it falls to a certain price, limiting potential losses.
Example: You buy a stock at $100 and set a stop-loss at $90. If the stock falls to $90, it automatically sells.
Short Selling
What it is: Borrowing shares and selling them immediately, hoping to buy them back later at a lower price.
Why it matters: Short selling allows investors to profit from falling prices but carries theoretically unlimited risk since stock prices can rise indefinitely.
Short Squeeze
What it is: When a heavily shorted stock's price rises rapidly, forcing short sellers to buy shares to cover their positions, driving the price even higher.
Famous example: GameStop in January 2021
Margin
What it is: Borrowed money from a broker used to purchase securities.
Why it matters: Margin amplifies both gains and losses. If investments decline enough, you may face a margin call requiring additional funds.
Margin Call
What it is: A broker's demand for additional funds when an account's equity falls below the required minimum.
Market Conditions
These terms describe the overall state of markets.
Bull Market
What it is: A market condition where prices are rising or expected to rise, typically defined as a 20%+ gain from a recent low.
Why it matters: Bull markets reflect investor optimism and often coincide with economic growth.
Bear Market
What it is: A market condition where prices are falling or expected to fall, typically defined as a 20%+ decline from a recent high.
Why it matters: Bear markets can last months or years and often accompany economic recessions.
Correction
What it is: A decline of 10-20% from a recent high.
Why it matters: Corrections are normal and healthy. The S&P 500 has historically experienced a correction roughly once per year.
Rally
What it is: A sustained increase in stock prices.
Volatility
What it is: The degree of price fluctuation in a security or market.
Why it matters: Higher volatility means bigger price swings—both up and down. The VIX index measures expected S&P 500 volatility.
VIX (Volatility Index)
What it is: Often called the "fear index," the VIX measures expected volatility in the S&P 500 over the next 30 days.
Benchmarks:
- Below 15: Low volatility, calm market
- 15-25: Normal range
- Above 25: Elevated fear
- Above 35: High fear/panic
All-Time High (ATH)
What it is: The highest price a stock or index has ever reached.
Support Level
What it is: A price level where a stock tends to stop falling because buying interest increases.
Resistance Level
What it is: A price level where a stock tends to stop rising because selling pressure increases.
Investment Vehicles
Different ways to invest your money.
ETF (Exchange-Traded Fund)
What it is: A fund that trades on an exchange like a stock and typically tracks an index, sector, or theme.
Examples: SPY (tracks S&P 500), QQQ (tracks Nasdaq-100)
Why it matters: ETFs offer instant diversification with low fees and can be bought and sold throughout the trading day.
Mutual Fund
What it is: A pooled investment vehicle managed by professionals that invests in a portfolio of securities.
Key difference from ETFs: Mutual funds are priced once daily and often have higher fees.
Index Fund
What it is: A fund designed to match the performance of a specific market index.
Why it matters: Index funds offer broad market exposure with minimal fees. They're a cornerstone of passive investing strategies.
Hedge Fund
What it is: A private investment fund that employs various strategies (often including leverage and short selling) to generate returns.
Why it matters: Hedge funds are typically only available to accredited investors with high net worth.
REIT (Real Estate Investment Trust)
What it is: A company that owns, operates, or finances income-producing real estate.
Why it matters: REITs must pay out 90% of taxable income as dividends, making them popular for income investors.
Bond
What it is: A loan you make to a government or corporation in exchange for regular interest payments and return of principal at maturity.
Why it matters: Bonds are generally less volatile than stocks and provide steady income, making them useful for diversification and capital preservation.
Corporate Actions
Events that affect shareholders.
IPO (Initial Public Offering)
What it is: When a private company first sells shares to the public.
Why it matters: IPOs can offer early access to growing companies but often come with high valuations and volatility.
Secondary Offering
What it is: When a company sells additional shares after its IPO.
Why it matters: Secondary offerings dilute existing shareholders' ownership and can pressure stock prices.
Buyback (Share Repurchase)
What it is: When a company buys back its own shares from the market.
Why it matters: Buybacks reduce shares outstanding, increasing EPS. They signal management believes the stock is undervalued.
Merger
What it is: When two companies combine to form a single new company.
Acquisition
What it is: When one company purchases another company.
Spin-off
What it is: When a company creates a new independent company by selling or distributing new shares of an existing division.
Delisting
What it is: When a stock is removed from a major exchange.
Why it matters: Delisting often signals serious financial troubles and makes shares much harder to trade.
Sentiment & Analysis
Understanding market psychology and research methods.
Sentiment Analysis
What it is: The process of determining the emotional tone of text—whether it's positive (bullish), negative (bearish), or neutral.
Why it matters: Sentiment analysis helps investors quickly gauge market mood from news articles, social media, and earnings calls.
Pro tip: MoneySense AI uses AI-powered sentiment analysis to instantly evaluate financial articles and identify bullish or bearish signals.
Bullish
What it is: An optimistic outlook expecting prices to rise.
Bearish

Why it matters: Technical analysts believe past price patterns can predict future movements.
Due Diligence
What it is: The research and analysis done before making an investment decision.
Alpha
What it is: Investment returns above what would be expected from market movements alone.
Example: If the market returns 10% and your portfolio returns 15%, you generated 5% alpha.
Beta
What it is: A measure of a stock's volatility relative to the overall market.
Benchmarks:
- Beta = 1: Moves with the market
- Beta > 1: More volatile than market
- Beta < 1: Less volatile than market
Risk-Adjusted Return
What it is: Investment performance measured relative to the amount of risk taken.
Why it matters: A 20% return with high volatility isn't necessarily better than a 15% return with low volatility.
