What: In a volatile day of trading, FireEye (MNDT) shares fell as much as 11.4%. The stock has recovered slightly at the time of this writing, now down about 10.4%.

So what: Without any announcements today, or key news regarding the stock, the decline was likely driven primarily by an overall sell-off of many growth stocks, along with a general market pullback. At the time of this writing, the S&P 500 is down 2% during the trading day, and the Nasdaq Composite index is down about 3.4%. For the week, the S&P 500 is currently on track for its biggest decline since the beginning of the year. 

Now what: Given that there's not any direct news about the company that sparked the stock's pullback, there aren't any new conclusions to be made about the company. Of course, if macroeconomic conditions worsen, and it begins to negatively impact the business, then investors can revisit what that would mean at that point.
