Why Pure Storage Inc (PSTG)’s Shares Plunged on Thursday?

It’s been a quiet day on Wall Street as the prices of the major indexes are roughly flat on the day as investors look forward to the upcoming GDP release on Friday. Meanwhile, Pure Storage Inc (NYSE:PSTG) is 16% in the red today after the tech company reported a loss of $0.22 per share on revenue of $139.9 million for its first quarter, beating estimates by $0.01 per share and $1.77 million respectively. Although the earnings were better than analysts’ estimates, they were below the market’s expectations on the account of Pure Storage’s previous big beats. The quarterly non-GAAP  gross margin was 67.3%, up by 6.8 points year-over-year. The second quarter guidance includes revenue in the range of $153 million to $157 million, versus the $153.8 million analysts expect. The company didn’t issue full year guidance.
