The Top 5 Penny Stocks This Week with Gains Over 500%

penny stock winnersNearly all of this week's top five penny stocks posted triple-digit gains, with the No. 1 penny stock boasting gains of nearly 525%.

We release a new top penny stocks list every week for our readers. We explain why these penny stocks posted big gains and give readers a snapshot of their companies...

Most of the top penny stocks we follow appear on the most reputable exchanges, such as the New York Stock Exchange or Nasdaq. These exchanges have stricter standards than Over-the-Counter (OTC) stock exchanges.

For instance, the Nasdaq wants listed companies to have an aggregate cash flow greater than $27.5 million in the prior three fiscal years, among other requirements.

And one of the requirements for the New York Stock Exchange calls for companies to have an aggregate pre-tax income of at least $10 million for the last three years.

While penny stocks on these two exchanges almost never trade for less than $1 (or else they'll be kicked off the exchange), they mostly trade for $10 or less. And they come with far less risk than OTC penny stocks.

Risk is the most important thing to understand when investing in penny stocks. These bargain stocks can bring you windfall profits, but are also known for big upswings and downswings. That's why Money Morning experts recommend limiting your portfolio to just a few high-quality penny stocks.

Money Morning Chief Investment Strategist Keith Fitz-Gerald also says it's vital to have the right mindset when searching for penny stocks. Not every penny stock will return you huge, triple-digit gains like the ones on our top five list. And the stocks that have surged one week might tank another.

That being said, here are our top five penny stock gainers this week...
