How to find undervalued stocks and check whether they are really cheap

Find a candidate worth investigating#

A screener can find companies trading at lower multiples than peers or their own history. A business you already know can be a starting point too. Write down why it looks cheap: perhaps its earnings multiple fell, or the share price dropped after disappointing results. That is the explanation you need to test.

A five-lens check of the business#

Helmbeam is our stock-research app for examining companies and following how their financial evidence changes over time. We group that evidence into five lenses: Business, Earnings, Shareholders, Resilience and Price. Each focuses on a different question, from how sales are growing to what the share price already expects. You can use them to test the assumptions behind an apparent discount.

Snapshot is the company-page summary. Begin with the latest dated reading, then use Numbers to inspect the financial measures available to you and move between reported quarters. A missing reading leaves a question unanswered. Keep a single quarter separate from trailing twelve months, which means the latest four quarters combined.

The example below uses a fictional manufacturer, Northbridge. Its figures are hypothetical, in US dollars, and compare two full twelve-month periods. They illustrate how an apparently inexpensive share can raise several different concerns.

1. Business: is revenue growth holding up?#

Northbridge's revenue rises from $100 million to $108 million, an 8% increase. The reported sales total is $8 million higher. You still need to know how much came from higher prices, more units or an acquired business. Growth caused by an acquisition does not establish that the existing operation sold more.

In Numbers, Business includes revenue, revenue growth and gross margin, with a segment breakdown where available. Compare the same quarters a year apart and then the twelve-month figures. A seasonal business can have a strong holiday quarter followed by a quieter quarter without demand deteriorating.

Read the company's explanation of the change. For a manufacturer, falling order volumes alongside higher prices would give a different outlook from rising demand at stable prices. In US filings, the business description and management's discussion explain the operation and material changes in results. The SEC's report-reading guide identifies where those disclosures belong.

If your estimate assumes continuing sales growth, evidence that demand is weakening should change that assumption.

2. Earnings: does selling more produce more operating profit?#

Suppose Northbridge's operating profit falls from $10 million to $8 million while revenue grows. Operating margin, calculated as operating profit divided by revenue, falls from 10% to about 7.4%. The business sells more but keeps less profit from each dollar of sales. Higher input costs, discounting or extra running costs could explain the change; the report needs to establish which.

For an operating business such as this manufacturer, our Earnings lens uses operating profit after a standard 21% tax adjustment and examines its direction over twelve months. This standard adjustment is a modelling convention, not the company's actual tax bill. In this example, $10 million becomes $7.9 million after that adjustment, while $8 million becomes $6.32 million. Reported net income and earnings per share, or EPS, appear separately in Numbers. For banks, insurers and real estate trusts, check the sector earnings measure named in the reading instead of applying the manufacturer's formula.

That distinction matters when a share looks cheap on reported earnings. An asset-sale gain or tax benefit can lift net income while the operation weakens. Check the income statement and its notes before assuming the latest EPS will recur. The SEC's financial-statement guide explains how operating profit differs from the final net-income figure.

For your estimate, decide whether the lower margin is temporary and what evidence supports a recovery. If restoring the old margin is essential to your valuation, write that assumption down explicitly.

3. Shareholders: does the growth reach each share?#

Now suppose Northbridge's share count increases from 10 million to 12 million. For this simplified example, assume each count applies throughout its respective twelve-month period. Revenue per share changes as follows:

Revenue grows 8%, but revenue per share falls 10%. Someone holding the same number of shares owns a smaller percentage of a larger company. Revenue per share measures sales attributable to each share; it is not profit or a cash payment to you.

Our Shareholders lens examines revenue per share alongside stock pay as a percentage of revenue. Numbers also shows share-count measures. Look for what caused issuance and what the company received for it. New shares might fund an acquisition, pay employees or raise cash to meet obligations. Investor.gov explains why companies issue shares.

Issuance can finance useful growth. Your valuation still needs to allow for the resulting share count and further potential dilution. A forecast for the whole business can improve while the estimated value of each existing share falls. Check the share and compensation notes rather than treating the stock-pay percentage as the total dilution.

4. Resilience: can the company finance the wait?#

Northbridge has $6 million of unrestricted cash. In a separate forward-looking cash scenario, assume it uses $4 million over the coming year after normal capital spending and must repay $4 million of debt in that year. There is no other cash inflow, refinancing or committed facility available in this example.

The cash calculation is $6 million minus $4 million minus $4 million, leaving a $2 million shortfall. Positive accounting profit would not remove that funding need. Cash can be absorbed by inventory, unpaid customer bills or investment even when an income statement shows a profit.

Our Resilience lens examines financial room and, where available, its direction over four quarters. In Numbers, you can inspect cash, debt, short-term coverage and funding runway. Use those to identify pressure, then inspect the maturity dates, restrictions and loan conditions in the filing. A cash balance alone does not tell you when obligations fall due. The SEC's report-reading guide points to liquidity and capital resources in management's discussion, as well as the financial-statement notes.

If your case depends on a recovery in two years but the company needs funding within one, investigate how it gets through that gap. Refinancing may cost more, and issuing equity can change the per-share calculation. Leave the funding question unresolved until there is evidence for an answer.

5. Price: what expectations are already in the share price?#

Our Price lens describes market expectations at the date of the reading. For a results reading, the price basis is the close after those results. Check the reading date before comparing the price with today's quote. Labels such as "Growth is priced in" describe that dated assessment; they do not provide your personal fair-value estimate or a buy instruction. In Numbers, the price move after a report is shown as context.

Northbridge's higher revenue comes alongside weaker operating profit, declining revenue per share and a funding gap. Consider those findings when judging the expectations in the price. A lower share price might reflect those problems; you still need to assess whether the price allows enough for them.

Compare P/E on the same earnings basis

For profitable companies, price-to-earnings is one way to compare the price with reported profit. P/E equals share price divided by earnings per share, as defined in the SEC's financial-statement guide. Use reported EPS for this calculation, not the Earnings lens's after-tax operating-profit total.

Continue with Northbridge. To get from its $8 million operating profit to earnings for common shareholders, assume annual interest expense is $1 million, tax is 21% of the remaining profit and there are no other income, expense or preferred-share claims. These are additional assumptions for our fictional company; the standard tax adjustment in our Earnings lens does not supply them.

Profit before tax is $8 million minus $1 million, or $7 million. Tax is $1.47 million, leaving $5.53 million for common shareholders. Dividing by the 12 million shares assumed throughout the year gives annual EPS of about $0.461. At an assumed $5 share price, Northbridge's trailing P/E is about 10.85, calculated using the unrounded EPS.

The $6.32 million after-tax operating-profit figure from the Earnings lens would give about $0.527 per share. It is higher because that calculation has not deducted interest. Substituting it for EPS would make the shares look cheaper on P/E than they are under these assumptions. The SEC's income-statement explanation follows operating profit through interest and tax to net income.

Keep trailing reported earnings, adjusted earnings and forward forecasts separate. A forward P/E uses an estimate of future EPS. Companies with losses need a different valuation method because a negative P/E does not give a useful cheapness ranking. Their value depends on future cash generation, financing and the shares needed to fund the path there.

Turn the five findings into a valuation range#

Northbridge first needs to cover the $2 million cash shortfall. Suppose it raises exactly that amount by issuing 400,000 shares at $5 each, with no fees. The count rises from 12 million to 12.4 million. After the planned cash use and debt repayment, the $6 million opening cash plus the $2 million raised has all been used. There is no cash cushion in this funding scenario.

Now estimate a full twelve-month period after that financing and repayment. Hold revenue at $108 million and assume annual interest expense on the remaining debt is $1 million. Use a 21% tax rate, no other earnings adjustments and 12.4 million shares throughout that forecast period. Any further funding need would require another revision.

Compare Northbridge's current operating margin with a recovery to its earlier 10% margin:

The first column retains the unrounded current margin, $8 million divided by $108 million; 7.4% is its rounded label. Both share-value calculations use unrounded EPS. Holding the multiple at 10 lets you see the effect of margin recovery without also assuming the market pays a higher multiple.

At the assumed $5 market price, Northbridge sits above the $4.46 no-recovery case and below the $6.24 recovery case. The higher estimate depends on restoring the margin and completing the financing on the stated terms. Without the extra 400,000 shares, the same recovered profit would produce about $0.645 EPS. Funding reduces that to about $0.624.

You still need to justify the multiple and the recovery timetable. Ten times earnings is an illustrative assumption, not a recommended multiple or our price target. A recovery that takes several years, a lower issue price or higher interest costs would change the comparison. Two peers can also both be expensive, so the lower P/E alone cannot establish a discount to value. The stock-valuation walkthrough shows how to value dated cash flows and test assumptions.

All five findings now affect the estimate: sales set the revenue base, margins determine operating profit, share issuance changes each share's claim, funding determines whether the business can reach the forecast period, and price tells you what you would pay against those conditional outcomes.

Decide what would change your view#

Record the next evidence you need. Northbridge's next results could show whether operating margin and revenue per share recovered. A financing announcement could resolve its cash gap while introducing higher interest costs or additional shares. Each development changes a different part of the estimate.

When returning to Helmbeam, compare the new reading with the one you used. Numbers lets you inspect available quarterly and twelve-month measures. With Pro, Timeline's Company history lets you revisit dated updates and filter by lens, while the full reading includes what to watch. Read a past assessment using the information and price date it shows.

A stock can remain below your estimate for years, and the estimate itself can be wrong. Specify the result that would make you reduce it: continued margin decline, another large issuance or funding on worse terms than you assumed. That gives you a reason to revise the case when the evidence changes.
