Many investors like trading low-priced stocks because any change in price results in bigger-percentage gains (and losses). But because there's a notable risk to these stocks, traders often wait for some sort of confirmation that the shares are on a bullish path.

Investors could do that by looking at rallying stocks -- i.e., companies that are increasing in value at a rapid rate. It's believed that the momentum behind these names can keep the stocks running on an upward trend for days and weeks to follow, especially if the rally is complemented by high trading volume.

What's more, investors like to know what the big institutional buyers on Wall Street are up to. It's often thought that the more intelligent traders are the ones calling the shots in these big hedge funds, so when there is net buying of shares by these institutions, Main Street investors can consider those purchases a strong vote of confidence in the stock's future.

Here's more information about "rallying" and "institutional buying" and why investors often use this data as trading signals. Below is a list of stocks that have met all these criteria.

The comeback kids
When a stock is rallying, it means it is performing above its moving average for a given time period. When a stock is trading above its 20-day moving average, or MA, as well as its 50- and 200-day moving averages, it signals bullish momentum. All the stocks in this list are rallying above their 20-, 50-, and 200-day MA.

The big backers
Institutional investors are also known as "big money" investors. They manage large pools of money, such as mutual funds and hedge funds.

Because institutional investors handle such large amounts of money, it is easy enough to assume that the big money-managers know more than the average investor. This is why these investors are also sometimes referred to as "smart money," and why their trades are so closely followed.
