Blue chips are better equipped to handle any possible downturns in the market and their bulk offers advantages in a slowing and uncertain economy. These include their larger dividends, ability to acquire floundering smaller competitors and lower volatility.

In addition, the long-term trend of the falling U.S. dollar will help the mega-caps. A weaker dollar bestows firms selling overseas a cheaper product in local currencies. This also pads their own books when strong currency revenue is converted back into dollars. Larger companies tend to have more of their overall revenue derived from international markets versus smaller domestic firms.
