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 talent management software maker Taleo (Nasdaq: TLEO) have soared by 17% after Oracle (Nasdaq: ORCL) agreed to acquire the company for $1.9 billion.

So what: The deal comes out to about $46 per share, a roughly 18% premium over yesterday's close. The move is notable because Taleo follows in rival SAP's (NYSE: SAP) footsteps when it similarly acquired SuccessFactors (NYSE: SFSF) a couple of months ago for $3.4 billion.

Now what: The SuccessFactors deal carried a heftier 52% premium. Oracle exec Thomas Kurian said, "Human-capital management has become a strategic initiative for organizations. Taleo's industry-leading talent-management cloud is an important addition to the Oracle Public Cloud." With the recent streak of Goliaths swallowing Davids, don't be surprised if consolidation within the cloud software sector continues.
