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 building-materials supplier USG (NYSE: USG ) fell more than 12% in early trading on a 50% increase in volume. The stock closed off a little more than 10%.
So what: Not even a month after buying in, Big Money investors appear to be selling in the wake of a lousy third-quarter earnings report. Management cited low demand in explaining a $0.48-per-share miss two weeks ago.
Now what: I'm usually reluctant to bet against a Warren Buffett holding -- and Berkshire Hathaway (NYSE: BRK-A ) (NYSE: BRK-B ) continues to own more than 16% of USG's shares outstanding -- but there's little to like about the company's numbers or projections. Analysts see losses persisting through at least 2013, according to S&P Capital IQ. Do you agree with them? Would you buy shares of USG at current prices? Please weigh in using the comments box below.
