First, we want to share with you two of the best strategies for trading penny stocks. These strategies can help you avoid scams and bad investments that are so often associated with penny stocks.

When looking for the best penny stocks to buy now, look for companies listed on major exchanges. The Nasdaq and NYSEMKT exchanges have tougher requirements for penny stocks than the Pink Sheets or Over-the-Counter Bulletin Board.

For example, a company listed on the Nasdaq must have assets totaling at least $80 million. The NYSEMKT also has stringent requirements, as a company must have at least $750,000 in revenue in two out of the last three fiscal years to be listed.

This provides more safety when investing in hot penny stocks, but it's not the only way to find the best penny stocks to invest in...

As part of your research process, analyze a company's annual filings.

Filings are available to the public on the website for the U.S. Securities and Exchange Commission. A 10-K form will provide you with insight to the company's earnings, assets, and liabilities.

The filings will also let you know how much debt a company is in, which helps indicate if its stock is a good long-term investment.

Now that we've reviewed two of the best strategies for investing in hot penny stocks, let's take a look at some of the biggest gainers from last Friday, May 27.
