$69 Billion Mega-Deal: What CVS Health's Acquisition of Aetna Means for Investors

It's official. After a little over five weeks of speculation, CVS Health (NYSE: CVS) announced on Sunday that it was acquiring Aetna (NYSE: AET) for $69 billion. The combination of the two companies will create a healthcare giant with a market cap of around $135 billion -- making CVS Health the seventh-largest healthcare company in the world.

But will bigger necessarily be better for CVS Health investors? Big deals make big headlines. However, they don't always turn out to be as great as their hype. In this case, as is often true with megadeals, there are both positives and negatives for investors.
