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 TeleTech Holdings (TTEC 1.81%) jumped more than 11% Tuesday after the company announced an acquisition, an increased share repurchase authorization, and solid fourth-quarter results.

So what: Adjusted quarterly revenue rose 11.6% to $326.3 million, which translated to 18.6% growth in non-GAAP net income to $24.1 million, or $0.47 per share. Analysts, on average, were looking for adjusted earnings of $0.38 per share on sales of $303.18 million.

For the full year 2014, TeleTech expects year-over-year revenue growth "between four and six percent from $1.24 to $1.26 billion," including an expected 2% negative impact from foreign exchange rates. Analysts were only modeling 2014 sales of $1.24 billion.

In addition, TeleTech increased its share repurchase authorization to $25 million. As of Dec. 31 -- and after repurchasing 2.48 million shares for a total of $56.5 million in 2013 -- TeleTech had roughly $18.9 million remaining under its existing authorization.

Finally, TeleTech announced it intends to acquire Bulgaria-based Sofica Group in a move to expand its geographic footprint and language capabilities. The transaction is expected to close by the end of February, and financial terms weren't released.

Now what: Even given TeleTech's modest top-line growth, shares look reasonably priced trading just under one times sales and 13 times this year's expected earnings. That's not quite cheap enough for me to want to dive in head-first, but I think investors would do well to at least keep TeleTech on their watch lists going forward.
