3 Stocks to Watch in September

Betting against a stock market's bullish run is often not a good idea. There's an adage warning investors against shorting stocks because "the market can remain irrational longer than you can remain solvent," but it also makes sense because bull markets typically last longer than market crashes, recessions, or even depressions.

While stocks typically fall much faster than they rise, over the past 30 years the stock market's gains have far eclipsed the relative declines. Even the Great Recession that was brought about by the financial markets' 2008 collapse only lasted about 18 months (though the effects were felt for much longer).
