What it is
Fundamental analysis judges a company by the business behind the stock: how much it sells, how much of that it keeps as profit, how fast both are growing, how much cash and debt it carries, and how much you are paying for all of it. The share price is treated as the result, not the thing being studied.
The idea is simple. Over a few months a stock moves on stories, fund flows and fear. Over years it follows the business. If revenue and earnings keep growing and margins hold up, the price tends to follow, because the company is genuinely worth more. Owning a stock is owning part of a business, and fundamental analysis is how you check the business.
The four things to check
- Growth. Is revenue growing, and is the growth holding up or slowing? Are earnings growing faster than revenue? See Revenue growth (TTM and forward) and EPS growth (TTM and forward).
- Profitability. How much of each sale does the company keep? High and rising margins usually mean pricing power. See Gross margin, Net margin and Return on invested capital (ROIC).
- Balance sheet. Could the company survive a bad year without raising money or selling shares? Cash above debt is the simplest test. See Balance sheet strength: cash versus debt.
- Valuation. Is the price reasonable for the growth you are getting? A great company at a silly price can still be a poor investment for years. See P/E ratio (price-to-earnings) and PEG ratio.
A company worth owning usually passes all four. A company that passes three and fails valuation belongs on a watchlist until the price comes back into line.
The order matters
Start with the business model, then the financials, then valuation. If you cannot explain in two sentences how the company makes money, the numbers will not help you. The full process is on How to research a company.
Fundamentals versus technicals
Technical analysis studies price and volume patterns, such as the Relative Strength Index (RSI) or the The 200-day moving average. Those tools cannot tell you whether a business is good. An individual stock can fall to zero, so what you own matters most. A broad index cannot realistically go to zero, so for index funds timing signals are more useful. The split is explained on Fundamentals vs technicals.

Questions
Is fundamental analysis better than technical analysis?
They answer different questions. Fundamentals tell you what to own; technicals can help with when to add money to an index fund. For individual companies held for years, fundamentals matter far more.
How long does fundamental analysis take?
A first pass on a company takes an hour or two: understand the business, check growth, margins and the balance sheet, then valuation. Following it after that means reading each quarterly report.
