BALTIMORE ( Stockpickr) -- With earnings season under way on Wall Street, it's time for market-players to create a powerful watch list of stocks due to report numbers that are also heavily shorted by the bears.

Short-sellers hate being caught short a stock that produces earnings that please the bulls. When this happens, we often see a tradable short squeeze develop as the bears rush to cover their positions and avoid big losses. Even the best short-sellers know that it's never a great idea to stay short once a bullish earnings report sparks a big short-covering rally.

This is why I scan the market for heavily shorted stocks that are about to report earnings. You only need to find a few of these stocks in a year to help enhance your portfolio returns -- the gains become so outsized in such a short timeframe that your profits add up quickly.

That said, let's not forget that stocks are heavily shorted for a reason, so you have to use trading discipline and sound money management when playing earnings short-squeeze candidates. It's important that you don't go betting the farm on these plays and that you manage your risk accordingly. Sometimes the best play is to wait for the stock to break out following the report before you jump in to profit off a short squeeze. This way, you're letting the trend emerge after the market has digested all of the news.

Of course, sometimes the stock is going to be in such high demand that you'll risk missing a lot of the move by waiting. That's why it can be worth betting prior to the report -- but only if the stock is acting extremely bullish technically and you have a very strong conviction that it is going to rip higher.

Here's a look at a number of stocks that could experience big short squeezes when they report earnings this week.
