Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of cyber-security company KEYW Holding Corp. (NASDAQ:KEYW) jumped as much as 10% today after being upgraded by an analysts.

So what: Analysts at Chardan upgraded the stock from a "neutral" rating to "buy" and put a price target of $14 on the stock. That indicates a 31% upside from the stock price late in the day.  

Now what: Stock pops that are driven by analysts upgrades don't often last long, and we saw that today, with shares trading up just 6% late in the day. I'll also point out that revenue dropped 18% in the first quarter and the company lost $0.06 per share. Conditions may be improving, but I'd wait to see an actual turnaround before jumping in and certainly wouldn't buy on an analyst pop today.
