This screen filters for profitable companies trading on low valuation multiples, meaning a low price relative to earnings, book value, and sales, rather than simply the cheapest tickers on the market.

To reduce the number of potential value traps, it also requires cash-backed earnings, manageable debt, and a current ratio above 1.2. These criteria provide additional context for interpreting a low valuation.

Value investing is the discipline of buying a business for less than it is worth and waiting for the gap to close. The core idea is a margin of safety, since paying a low multiple gives you a cushion if your estimate of the company's worth is too optimistic.

The hard part is distinguishing a genuine bargain from a company that is cheap because it deserves to be. That is why profitability and balance-sheet screens matter as much as the valuation ratios themselves.

A low multiple is a question, not an answer. For each candidate, run a fair-value estimate to test whether the price is actually below intrinsic value, and read the balance sheet for hidden risk.

Comparing a cheap stock against a stronger peer often reveals whether you are being paid to take on a real problem or picking up quality at a discount.
