Undervalued

Undervalued describes a security whose current market price is believed to be lower than what it is actually worth. The idea depends on having some estimate of "true worth," often called fair value, and comparing that estimate to the price the market is currently offering.

That estimate of true worth usually comes from a valuation model. For a stock, this might involve looking at company earnings, cash flow, assets, or growth prospects and building a projection of what the business should be worth, then comparing that to its market capitalization. For other instruments, like a futures contract or an option, "fair value" might come from a pricing formula that accounts for the price of the underlying asset, time remaining, interest rates, or expected volatility. If the model's output is higher than the current market price, the security is labeled undervalued.

The nuance that trips people up is that undervalued is an opinion, not a fact. It is only as good as the model and the assumptions feeding it. Two analysts can look at the same company and disagree on whether it is undervalued, because they used different growth assumptions, different discount rates, or different comparable companies. A security can also stay "undervalued" by one measure for a long time, or never converge toward that estimated fair value at all, because the market is pricing in risks or information the model does not capture.

It is also easy to confuse undervalued with cheap. A low price alone does not make something undervalued; a $2 stock can be wildly overvalued and a $400 stock can be undervalued. What matters is the relationship between price and the estimated worth, not the price by itself.
