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 The New York Times (NYSE: NYT) shot up 10% briefly today after AOL (NYSE: AOL) announced it was buying The Huffington Post.

So what: There wasn't any specific Times news driving the move, but when competitors are bought out investors like to speculate on who might be next. The Huffington Post is ad-supported, and The New York Times is planning on offering a subscription service as ad revenue declines.

Now what: AOL isn't exactly a company whose acquisitions I am inclined to copy, and considering the up and down day the market doesn't know what to make of it either. I am more concerned about falling ad revenue at The New York Times than the AOL acquisition and will keep an eye on how subscriptions like The Daily from News Corp. (Nasdaq: NWS) are received. I'm intrigued by the changing business models but not enough to be a buyer on today's AOL-Huffington Post news.
