The timing of Alphabet Inc. chief legal officer David Drummond’s sale of $145 million in stock ahead of the company’s CEO stepping down might seem curious. But his actions appear to be routine and should not alarm investors, according to an insider trading analyst.

“He’s received [stock] options in the past and has done the exact same behavior,” said Jasper Hellweg of Argus Research in New York. “If it was structured differently it would catch my eye differently. But these are options. It’s part of his compensation. It doesn’t seem like he’s unloading or trying to get out.”
