Tesla topped analysts’ revenue expectations in the second quarter, but the stock still moved sharply lower. The market response suggested investors were less interested in the sales beat than in what the quarter said about the company’s underlying financial strength.

The key issue was profitability. Even with revenue coming in ahead of forecasts, profit was described as running at less than half its more normal level. That points to a business generating far less bottom-line benefit from its sales than many shareholders expect from Tesla.

Cash flow also appeared to be a major concern. Rather than showing solid cash generation, the quarter indicated cash was being burned. For investors, that can be more alarming than a simple earnings miss because it raises questions about how expensive Tesla’s current strategy and future growth plans may be.

The selloff showed that a revenue beat alone was not enough to reassure the market. In Tesla’s case, weaker profit and cash moving in the wrong direction seem to have carried more weight than top-line performance, helping explain why the shares fell despite clearing the revenue bar.
