Should You Still Buy the Dow Jones' Best-Performing September Stocks?

September was a tough month for the Dow Jones Industrial Average (DJINDICES: ^DJI), but that wasn't the case for every Dow constituent. A small handful of the index's components managed to gain a bit of ground last month.

This raises a question: Are last month's rare rallies a sign of lasting growth, or are they just volatility-driven moves that will soon be unwound? If you look at the context of these bullish moves, you can make a reasonable decision regarding the Dow's best-performing stocks in September.

Last month's biggest Dow winners were UnitedHealth Group (NYSE: UNH), Amgen (NASDAQ: AMGN), and Chevron (NYSE: CVX), gaining 5.8%, 4.9%, and 4.7%, respectively, versus the Dow's loss of 3.5%.
