Value Investing 101

The strategy that turned Warren Buffett into the world's most successful investor. Here is how it works and why it still does.

What is value investing?

Value investing is the practice of buying shares in a business for less than the business is actually worth, then holding until the market corrects the mispricing. The core belief is that the stock market is a pricing mechanism that gets things wrong in the short term. Prices fluctuate with news, fear, and sentiment. But underlying business quality is more stable. When the price of a good business drops below its real value, that is a buying opportunity. When the market eventually recognises the quality, the price recovers, and the investor profits.

How does the stock market misprice things?

Markets move on information and emotion. When a company reports disappointing quarterly earnings, investors sell. The price drops. But if the business itself is fundamentally healthy — strong cash flow, manageable debt, durable competitive position — the price drop creates a gap between what the stock costs and what the business is worth. Value investors look for that gap.

What is intrinsic value?

Intrinsic value is the true underlying worth of a business, based on what it earns, what assets it holds, and how much cash it generates. There is no single formula. Analysts estimate it using earnings power, discounted cash flow models, and comparisons to historical multiples. The number is always an estimate, not a fact. That is why the next concept matters so much.

What is margin of safety?

Margin of safety is the gap between the price you pay and your estimate of intrinsic value. If you think a business is worth $100 per share and you buy at $70, your margin of safety is 30%. If your estimate turns out to be off and the business is only worth $85, you are still ahead. The margin of safety is a buffer against being wrong. Benjamin Graham, who invented this concept, called it the central concept of value investing.

The role of patience

Value investing does not work on a quarterly timeline. Mispricings can persist for months or years before the market corrects them. The investor who buys a good business at a fair price and holds for three to five years has a very different risk profile than someone trading on news cycles. Warren Buffett's favourite holding period is "forever." Most value investors aim for years, not months.

What kinds of stocks do value investors look for?

Value investors look for businesses with consistent earnings, strong free cash flow, low debt relative to earnings, and a history of generating returns on invested capital above the cost of capital. They also look for businesses that are temporarily unpopular — out of favour with the market for reasons that are short-term and fixable, not structural and permanent.

The Value Drawdown screener looks for stocks trading significantly below their 52-week high while still scoring well on earnings quality, FCF yield, and long-term trend. These are the classic ingredients of a value opportunity: a good business at a temporarily low price.
