But the stock is up 16.5% year-to-date and trades at a trailing price-to-earnings ratio of 175.
"You've had a stock that's hit 52-week highs, it's had an incredible run over the last few weeks," said JJ Kinahan, chief market strategist at TD Ameritrade. "That said, that makes me a little bit cautious going into earnings."
Still, the options market is pointing to a 6.5% move after earnings (on both the upside and downside), so of course there's high risk and high reward. "If you're already long the stock, do you think about maybe taking a little bit off the table, so you put some profit in your pocket," Kinahan said.
But what will Salesforce actually report? Watch its guidance, Kinahan said. It's forward looking statements will give investors the best idea they can have on where company performance may soon be, and therefore how attractive the stock is.
