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 IT specialist Insight Enterprises (Nasdaq: NSIT) soared 21% in intraday trading Tuesday after its quarterly results and full-year profit forecast easily blew out Wall Street expectations.

So what: Fueled largely by a double-digit jump in sales, Insight managed to grow its fourth-quarter profit 43% to $0.53 per share, versus the average analyst estimate of just $0.43 per share. President and CEO Ken Lamneck said, "The technology refresh cycle provided a nice tailwind for our business in 2010," and added that Insight even grew market share in certain segments.

Now what: Don't let today's big rally keep you away from Insight. The shares might be skyrocketing, but when you factor in management's full-year profit forecast, which also topped estimates, the company currently trades at a paltry forward P/E of 10.1. That's a discount to gorilla rivals like EMC and IBM, making Insight a relatively attractive tech bet, as well.
