Best Penny Stocks It's those double-digit gains in just a matter of days that draw investors to the best penny stocks...

While the best penny stocks can bring huge profits, most penny stocks are extremely volatile. That's why Money Morning experts advise that penny stocks should only represent a small percentage of your portfolio. And one penny stock should never account for more than 2% of your investing capital.

Money Morning Chief Investment Strategist Keith Fitz-Gerald says the key to finding the best penny stocks in 2016 is the same as finding any other stock to buy. You need to perform the proper research, have the right risk tolerance, and maintain perspective.

At Money Morning, we focus primarily on penny stocks listed on major exchanges like the NYSE and the Nasdaq. That's because they are less risky than penny stocks trading on the Over-the-Counter market or the Pink Sheets.

While they are slightly more expensive, they still offer the potential for substantial gains over a short time frame. And they're much less risky.

Here's our list of penny stocks to watch this week...

The 5 Best Penny Stocks to Watch This Week
