Shares of Irvine-based data analytics software maker Alteryx Inc. (NYSE:AYX) plummeted 11% and the reasons for the drop remained unclear.

“I’m not seeing anything Alteryx-specific to explain the move, I would point out that a lot of high-multiple names are getting crushed today, like Atlassian, Slack, Fastly, and Coupa, perhaps on fear of a potential economic slowdown,” Rishi Jaluria, a senior research analyst at D.A. Davidson & Co., told the Business Journal.

After the stock began its slide, Alteryx Chief Financial Officer Kevin Rubin made a previously scheduled presentation at the Raymond James Technology Investors Conference in New York.

“Someone asked if there’s any reason their stock is down 10% and management said no” at the conference, Jaluria said.
