Value Investing
Value investing is the discipline of buying a security for meaningfully less than a conservative estimate of what the underlying business is worth. The premise is that price and value diverge regularly, because markets price stories and moods faster than they price cash flows, and that the gap eventually closes in the investor’s favor.
The math
A hypothetical company is worth $80 per share by a sober estimate of its future cash flows. The market, bored with it, offers the stock at $50.
An investor buys 1,000 shares for $50,000. If price converges to value over three years, the position reaches $80,000: a 60 percent gain, roughly 17 percent annualized.
Now assume the estimate was 20 percent too generous and the business is only worth $64. Convergence still produces $64,000, a 28 percent gain.
| Estimate holds | Estimate 20% too high | |
|---|---|---|
| Business value | $80/share | $64/share |
| Position at convergence | $80,000 | $64,000 |
| Gain on $50,000 | +60% | +28% |
The discount absorbed the analytical error; that cushion is the entire point.
The trap
The value trap: a stock that is cheap on trailing numbers because the business is quietly dying. A declining company at 6 times earnings can stay at 6 times shrinking earnings forever, grinding the price down year after year.
Cheapness alone is a screen result, not a thesis. The question a low multiple never answers is why the market is offering the discount, and sometimes the market is right.
The move
Practice value on quality. The modern version of the discipline values earning power, competitive position, and reinvestment ability, not just assets, and would rather pay a fair price for a compounding business than a bargain price for a melting one.
This is where active selection earns its keep: an index owns the value traps and the compounders indiscriminately, while a careful picker gets to demand both a durable business and a visible gap between price and worth.
