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 Blue Coat Systems (Nasdaq: BCSI) rose more than 11% in early trading on news that it had entered a standstill agreement with investment firm Elliott Associates.

So what: The terms of the agreement prohibit Elliott from taking action in Blue Coat's stock until Oct. 25. In exchange, the firm will be granted access to the board of directors for the purposes of discussing possible merger or acquisition ideas. Or at least that's how the otherwise impenetrable legalese of this SEC filing reads to this Fool.

Now what: Could Blue Coat be entertaining buyout offers? Eric Savitz at Forbes suggests precisely that outcome here, and I think he's right. Cisco (Nasdaq: CSCO) is known to want a bigger slice of the wide area network optimization market that Riverbed Technology (Nasdaq: RVBD) controls. Acquiring Blue Coat could aid in the effort.
