Wall Street took a negative view of Facebook on Monday, as investors shaved more than 3 percent off the company’s stock price following what one brokerage said a “negative network effect” has hit the social networking giant over the last week.

Before the stock market opened, Needham & Co. analysts Laura Martin and Dan Median lowered their rating on Facebook to hold, or the equivalent of neutral, from buy. The pair said they took down their view of Facebook due to a slate of high-level executive departures from the company, and a rash of controversy over how Facebook’s platform was used to live-stream parts of the mass shootings that killed 50 worshippers at two mosques in Christchurch, New Zealand, on Friday.
