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 BancorpSouth (NYSE: BXS) closed off 15% when a marginal increase in third-quarter earnings fell shy of Wall Street estimates.

So what: Total assets for the banker serving the southeastern U.S. fell to $13.2 billion from $13.6 billion in last year's Q3. Deposits fell 1.2% to $11.1 billion while loans and leases fell 4.8% to $9.1 billion. On the bright side, non-performing loans fell 4.5% sequentially.

Now what: Yet that wasn't enough to impress investors focused on the bottom line. Bancorp South's $0.14 per share of profit was just a penny better than last year's Q3 -- and $0.02 short of what analysts had hoped for, according to data compiled by Yahoo! Finance.
