Cloud computing system vendor Nutanix suffered the biggest decline in its stock price in the first quarter of 2017 among all the IT companies on our watch list.

After hitting a high of $33.10 per share on Feb. 15, Nutanix shares fell through the rest of February and then declined more than 37 percent in March – with the share price falling from $31.12 at the close of trading March 2 to $23.00 at the close of trading March 3.

That came after the company reported financial results for its fiscal 2017 second quarter (ended Jan. 31) that include revenue of $182.2 million, up 77 percent from $102.7 million in the same quarter one year earlier. The company's loss for the quarter was $93.2 million, compared with the $33.2 million loss reported one year before.

Despite the solid revenue growth, the company issued guidance for the third quarter that apparently disappointed investors and analysts, leading to the March stock plunge.
