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 Brigham Exploration (Nasdaq: BEXP) flew up 20% today after Norway's oil giant Statoil (NYSE: STO) said it would buy it for $4.4 billion.

So what: The all-cash deal values Brigham at $36.50 per share and represents about a 20% premium to its Friday closing price. Statoil is making the move to strengthen its position in U.S. unconventional assets, but given the stock's 2% decline today, Wall Street doesn't seem overly thrilled with the purchase price.

Now what: I'd look into this little dip in Statoil as a possible entry point. The deal should give the company 375,000 net acres in the Williston basin, which has production potential from the largest oil accumulations in the country: the Bakken and Three Forks formations. When you couple that fresh growth potential with a solid, steadily growing dividend (currently yielding nearly 4%), Statoil's total return prospects seem too attractive to ignore.
