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 hardwood flooring giant Lumber Liquidators (NYSE: LL) jumped 10% higher today after an analyst upgrade.

So what: Cowen and Company upgraded Lumber Liquidators to outperform from neutral. Traders are buying shares at a torrid pace, with volume nearly three times the three-month average with three hours left in the trading day.

Now what: This is the classic analyst bump giving shares a lift today. With a price-to-earnings ratio of 25.2, Foolish investors may want to look at competitors like Lowe's (NYSE: LOW), which sports a P/E of 18.9 and pays a nice dividend. I'm going to leave Lumber Liquidators alone today as I usually do on analyst bump days.
