What happened 

Shares of LifeLock Inc. (NYSE:LOCK) jumped a whopping 47.9% in November, according to data provided by S&P Global Market Intelligence, after the security company agreed to a buyout offer. 

So what 

LifeLock agreed to sell itself to Symantec Corporation (NASDAQ:SYMC) in a deal worth $2.3 billion. The deal will pay LifeLock shareholders $24 per share in cash and create the "largest digital safety platform for consumers and families." 

The acquisition is expected to close in the first quarter of next year and won't impact Symantec's fiscal 2017 results. 

Now what 

For LifeLock shareholders, there's not a lot of upside, with the stock currently trading at $23.90 per share. That indicates investors think there's a high likelihood the deal will close and fairly soon. With the cash offer, the downside risk is probably growing in the event the acquisition does fall through and there's little upside in the form of Symantec shares. With that in mind, it may be time to take some or all of your shares off the table and find new opportunities after LifeLock's huge bounce in November.
