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 homebuilder PulteGroup (NYSE: PHM) jumped 10% briefly today after the company was upgraded by an analyst.

So what: Ticonderoga Securities thinks PulteGroup shares have gotten so cheap investors shouldn’t pass them up. Analyst Stephen East doesn’t think home sales will drop much more, and the company’s price/book value and normalized EPS multiples are at attractive levels. Of course, this comes a day after RBC Capital Markets analyst Robert Wetenhall said he was bearish on homebuilders and expects housing prices to decline further.

Now what: I’ve been hearing about a homebuilder recovery for years, and it never quite seems to take hold. Home prices may be stabilizing, but there is still a ton of inventory on the market that homebuilders have to compete against. This Fool just can’t get excited about a company posting losses in a housing market that is flat at best.
