The Dow, S&P 500, and Nasdaq closed out last week with gains of 1.51%, 1.58%, and 1.91%, respectively. But this list of penny stocks features five small-cap stocks that all ended the week with double-digit gains.

Investors are always on the lookout for hot penny stocks because they can post double or triple-digit profits in short periods of time.

That's why we compiled this list of penny stocks to watch. Each has posted a double-digit gain in the last week...

List of penny stocksWhile penny stocks can bring huge profits, they can also bring high volatility. That's why Money Morning experts advise that penny stocks should only represent a small percentage of any portfolio. And one 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 strong investment. Know what to look for and have the right risk tolerance and 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 don't trade for pennies per share, they still offer the potential for substantial gains over a short time frame.

Here's our list of penny stocks to watch this week and the huge profits they've brought investors...
