Shares of hacker-prevention software provider CrowdStrike (CRWD)  were lower in premarket trading Friday after Goldman Sachs analyst Heather Bellini cut her recommendation to sell from neutral and lowered her 12-month price target on expectations the stock price has already baked in much of its own positive news.

In a research note to clients, Bellini said that while CrowdStrike is well-positioned in the market for endpoint security and can continue to post earnings to the upside of Wall Street forecasts, a "blue sky analysis" suggests this is already priced into the stock at current levels.

She lowered her one-year price target to $66 from $83.

CrowdStrike shares took a big hit last month, despite reporting a fiscal second-quarter loss that was narrower from a year ago and also narrower than analysts' forecasts.

The Sunnyvale, Calif.-based company, whose claim to fame is that the FBI used it to assess the Russian hacking of the DNC, posted a non-GAAP net loss of $23.1 million, or 18 cents a share, vs. a loss of $30.4 million, or 69 cents a share, in the comparable year-ago quarter.

Separately, Bellini upgraded Workday (WDAY - Get Report) to buy from neutral, and also noted that additional "blue sky" analysis points to Zoom Video (ZM) , Slack Technologies (WORK)  and Elastic (ESTC) as having the highest potential upside to 2020 estimates.

Shares of CrowdStrike were down 4.62%, or $2.84 a share, at $58.57 in Friday trading.
