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 customer service technologist LivePerson (NASDAQ:LPSN) surged 23% today after its quarterly results impressed Wall Street.

So what: LivePerson shares plummeted in May after the loss of a major customer, but today's solid Q3 results -- adjusted EPS of $0.07 on a revenue increase of 14% -- are giving analysts plenty of good vibes over its turnaround prospects. In fact, the company signed a total of 163 deals during the quarter and added 55 new enterprise and midmarket customers, suggesting that management's strategic shift to a broader product offering is working wonders.

Now what: Management now expects adjusted EPS of $0.04-$0.06 on revenue of $46 million-$47 million, pretty much in line with Wall Street's view of $0.06 and $47.1 million, respectively. "We continue to grow the depth and quality of relations with our existing base," said Chairman and CEO Robert LoCascio in a conference call. "With the rollout of our LiveEngage platform, a growing number of our customers are leveraging the broader capabilities of our solutions and driving greater business value to our multichannel engagement strategy." More important, with LivePerson shares still off about 25% from their 52-week highs even after today's surge, there might be plenty of room left to run.
