Value Investing
Definition
An investment strategy focused on buying stocks trading below their estimated intrinsic value, seeking companies where the market price doesn't reflect the underlying business worth.
Value investing was formalized by Benjamin Graham and David Dodd in the 1930s and later championed by Warren Buffett. The core principle is simple: buy stocks for less than they're worth. In practice, this means identifying companies where the market price is significantly below the estimated intrinsic value based on fundamentals like earnings, book value, cash flow, and dividends.
Value investors look for stocks with low P/E ratios, low price-to-book ratios, high dividend yields, and strong fundamentals that the market has overlooked or overreacted to on the downside. The "margin of safety" — the gap between price and intrinsic value — provides a buffer against errors in valuation.
The value factor has been one of the most documented sources of excess returns in finance. Over very long periods, value stocks have outperformed growth stocks. However, this relationship reverses for extended periods — value significantly underperformed growth from 2007-2020, leading some to question whether the value premium has permanently diminished.
Value investing requires patience and contrarian thinking. You're buying stocks that the market has punished, which often means buying into companies facing challenges or negative sentiment. The emotional discipline to buy when everyone is selling is what makes value investing difficult in practice.
Modern approaches to value investing include quantitative value strategies (using algorithms to screen for undervalued stocks), deep value (buying extremely cheap companies that may be distressed), and quality value (combining value metrics with profitability and financial strength indicators).

Frequently Asked Questions
Is value investing still effective?
Over very long periods, value stocks have historically outperformed. However, value significantly lagged growth stocks from 2007-2020 before a partial reversal. Most academics believe the value premium still exists but is smaller and more cyclical than historically. Diversifying across value and growth is prudent.
How do I find undervalued stocks?
Screen for stocks with low P/E, price-to-book, and price-to-free-cash-flow ratios relative to their industry. Look for companies with strong balance sheets that have been beaten down by temporary problems. Value ETFs (like VTV or SCHV) offer diversified value exposure without individual stock picking.
