Why Profitable Companies Can Still See Their Stock Prices Fall

Cisco reported record quarterly revenue of $17.3 billion on August 12, 2026, up 18% from a year earlier, and issued guidance that beat analyst estimates. Its shares still fell 8.4% the next day, CNBC reported.

The reaction is less puzzling than it looks. Profit describes what a company has already earned. A share price reflects what investors expect it to earn in the future, and how much they are willing to pay for that.

Prices move on expectations

Analysts publish forecasts before every earnings report, so markets react to the gap between results and expectations, not to results alone.

Barclays found that the second-quarter 2026 reporting season was unusually strong, with an average earnings surprise of 30.7% against a historical average of 5.2%. Even so, stocks fell on average after both beats and misses. Barclays attributed that to elevated expectations and crowded positioning, according to a Yahoo Finance report on August 14.

Cisco fits the pattern. Its shares had risen more than 60% this year before the report, CNBC said. Analysts at Piper Sandler, who rate the stock a hold, wrote that the outlook looked conservative given demand, and that some investors "may start to nitpick that we're seeing peak growth."

The business itself was healthy. Cisco's filing shows GAAP net income of $3.9 billion for the quarter and fiscal 2026 revenue of $63.3 billion, up 12%.

Valuation leaves little room for error

When investors have already paid a high price for a stock, much of the good news is built into it. A strong quarter then has to be better than strong to lift the shares. A stock that has run far ahead of earnings can fall on results that would have been welcomed a year earlier.

Guidance, growth and margins

Lululemon shows how slowing sales and a lower outlook can outweigh a profit. On September 3, it reported diluted earnings of $2.92 per share, down from $3.10 a year earlier. That included $134.5 million of tariff refunds, which the company said added 560 basis points to its operating margin. Net revenue fell 4% to $2.4 billion and comparable sales fell 9%. Operating margin narrowed to 18.8% from 20.7%.

Lululemon also cut its full-year earnings guidance to $9.48 to $9.73 per share from $10.95 to $11.15, Benzinga reported. It guided third-quarter revenue down 10% to 11%. Shares closed on September 4 near $101, about 17% below the prior close of $121.77, according to TIKR and SentiSense.

The company was still profitable, earning roughly $329 million in the quarter. The market was weighing where the business is heading, not what it had just earned.

Walmart's case is subtler. On August 20, it reported revenue of $187.9 billion, up 5.9%, and raised its full-year adjusted earnings guidance to $2.80 to $2.87 per share from $2.75 to $2.85. But its third-quarter guidance of $0.62 to $0.64 was level with the $0.62 it earned a year earlier.

CFO John David Rainey said tariff refunds received in the second quarter would go into prices and customer experience in the second half, and urged investors to read the two quarters together. Shares fell about 9% that day, from $114.30 to $103.84, 24/7 Wall St reported.

Rates and bond yields

Interest rates change the comparison investors make. The 10-year Treasury yield reached about 5.36% on October 7, its highest since 2002, NBC News reported. It closed at 5.22% on October 8, according to Federal Reserve data. Minutes of the Fed's September meeting showed it had raised rates for the first time since 2023, Kiplinger reported.

Higher yields affect stocks in two ways. A bond that pays more makes shares less attractive by comparison. And profits expected years from now are worth less today when discounted at higher rates, which tends to weigh most on companies whose value rests on distant growth.

The S&P 500 fell 0.67% on October 8 to 7,749.83, after record highs earlier in the week, Yahoo Finance reported. Higher oil prices were also cited. Yields were one factor among several.

Dividends and selling

Dividends and buybacks do not guarantee a rising price. Cisco returned $12.7 billion to shareholders in fiscal 2026, equal to 99% of free cash flow, according to its earnings call. Its shares still fell after the report.

Investors may sell for reasons unrelated to a company's health: locking in gains after a rally, rebalancing a portfolio, or moving money into assets they now find more attractive.

A good business is not always a good price

A profitable business earns more than it spends. An attractive valuation means the price paid is reasonable for what that business may earn in the future. A company can meet the first test and fail the second.

A falling share price therefore does not by itself signal financial weakness. Cisco and Walmart grew sales and profit. Lululemon's shrinking revenue points to a real operating challenge. Each saw its shares fall, for different reasons.

Investors look at both because each answers a different question. Financial performance shows how well a company runs today. The price shows how much of its future the buyer is paying for in advance, and how much disappointment that price can absorb.
