What this transaction means for investors

Upon closer examination of CEO Corrigan’s stock sale, it shouldn’t warrant concern among investors. It merely looks like a routine transaction.

She conducted her share sale via a 10b5-1 trading plan. Certain terms, like sales timing, get set ahead of time. That makes it easier for executives and companies to avoid allegations that insiders sold ahead of material information that the public didn’t know.

Additionally, Corrigan sold some shares following an option exercise. She exercised options for 2,379 shares at a strike price of $29.05. That’s less than half the current share price. Then, she sold some shares partly to cover the option exercise and associated taxes. The executive still retains a multimillion-dollar position.

While the transaction shouldn’t raise any eyebrows, Exponent’s stock performance should give investors some pause. The shares lost 11.7% over the last year through July 17, including dividends. That’s well below the S&P 500 index’s 19.9% total return.
