What it means
Calling a share undervalued is a claim about the gap between two different numbers. Price is what the market will pay for it today, while value is what the business is genuinely worth based on the cash it can produce over its remaining life.
The idea matters to investors for the obvious reason that buying below value builds in a cushion if the future turns out worse than expected. It matters to company managers too, because a share price stuck below value makes raising new equity expensive and can attract a takeover bid from a buyer who spots the same gap.
Analysts test the claim in two broad ways. The first is intrinsic valuation, usually a discounted cash flow model that projects future cash and converts it into a value in today's money.
The second is relative valuation, comparing multiples such as price to earnings or enterprise value to operating profit against similar businesses. A low multiple on its own proves nothing at all.
Shares are often cheap for good reasons: shrinking demand, heavy debt, a pending lawsuit or a management team nobody trusts, and buying them anyway is how investors end up in what the industry politely calls a value trap. The word is used well beyond listed shares, covering property, private businesses, bonds and even brands.
The logic is identical in each case, but the further you move from a liquid public market the harder it becomes to tell whether the discount is a genuine bargain or simply the price of an asset that is hard to sell.
In practice
Real-world examples.
Example
A discount retailer issues a profit warning and its share price falls 30% in a week, leaving it on eight times earnings while the rest of the sector trades on fifteen. An analyst who believes the warning reflects one bad quarter rather than a permanent decline argues that the shares are undervalued. The whole case rests on whether next year's profits recover.
Example
A regional bank has tangible book equity of $600,000,000 but a market capitalisation of $420,000,000, so it trades at 0.7 times book value. Investors read that as a signal that the market doubts the quality of the loan book. If the loans perform, the shares are undervalued; if bad debts turn out worse than reported, the price is right.
Example
A family selling a warehouse quickly accepts $7,200,000 for a building a surveyor valued at $9,000,000, a discount of 20%. The buyer treats the property as undervalued because they can afford to wait for a proper marketing period. The seller treats the same discount as the fair price of speed.
Formula
Calculation
Two calculations do most of the work here:
Intrinsic value per share = estimated equity value / shares outstanding
Discount to value = (intrinsic value per share - market price) / intrinsic value per share
Take a listed components manufacturer with 10,000,000 shares trading at $18.00, giving a market capitalisation of 10,000,000 x $18.00 = $180,000,000. A discounted cash flow model built on the company's forecast cash flows produces an equity value of $240,000,000. Dividing $240,000,000 by 10,000,000 shares gives an intrinsic value of $24.00 per share.
The discount to value is ($24.00 - $18.00) / $24.00 = $6.00 / $24.00 = 25%. Put the other way round, if the price rose all the way to the estimated value the gain would be $6.00 / $18.00 = 33.3%. Those two figures are not the same thing, and confusing the discount with the potential upside is one of the quickest ways to overstate an opportunity.Case study
Seen in the real world.
Braithwaite Tooling is an illustrative, entirely fictional maker of precision cutting tools. Its shares sat at a market capitalisation of $180,000,000 while the balance sheet held $40,000,000 of net cash and the business earned $36,000,000 of operating profit. Stripping out the cash gave an enterprise value of $180,000,000 - $40,000,000 = $140,000,000, or under four times operating profit, against roughly eight times for comparable engineering groups.
A fund manager argued that the discount reflected one large customer contract that investors feared would not be renewed. She valued the business at eight times operating profit, or 8 x $36,000,000 = $288,000,000 of enterprise value, which after adding back the $40,000,000 of net cash implied equity worth $328,000,000, well above the $180,000,000 the market was paying.
The contract was renewed the following spring and the shares re-rated over the next eighteen months. In this illustrative case the gap closed, but the fund manager was candid that had the contract been lost, the cheap multiple would have looked entirely deserved.
Watch out
Common mistakes.
- Treating a low price to earnings ratio as proof that a share is undervalued, when the market may simply be pricing in falling profits.
- Comparing a company's multiple against businesses in a completely different industry with different growth rates and capital needs.
- Assuming that because a share price has fallen a long way it must now be cheap, which confuses a change in price with a gap between price and value.
Questions
People also ask.
How long does an undervalued share take to reach its value?
There is no reliable answer, and investors often wait years, which is why a margin of safety and patience matter more than precise timing.
Can a whole market be undervalued?
Yes, entire markets and sectors can trade below reasonable estimates of value, usually after a shock, though calling the turning point is notoriously difficult.
Is undervalued the same as cheap?
No, cheap describes a low price or a low multiple, while undervalued describes a price below estimated worth, and plenty of cheap assets are correctly priced.
