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 financial services company Knight Capital Group (NYSE: KCG) are ticking higher by 10% today following the company's robust fourth-quarter results.

So what: Knight Capital handily crushed Wall Street estimates this morning by reporting a quadrupling in its net income to $0.43 on a 31% jump in revenue to $341 million. These estimates compare to Street expectations of $0.26 and $321 million. The driving force behind the earnings blowout was strength in the company's Market Making segment which saw revenue grow 69% and pre-tax earnings jump 181% over the year-ago period.

Now what: If Knight Capital has proven anything over the past decade, it's that regardless of the trading conditions and consumers' willingness (or unwillingness) to take on risk, it can turn a healthy profit. Valued at nine times forward earnings and 81% of its book value, Knight could present shareholders with a nice bargain even after today's pop and should, if anything, be worthy of a spot on most investors' watchlists.
