 BALTIMORE (Stockpickr) -- At Stockpickr, we track daily portfolios of stocks that are the biggest percentage gainers and the biggest percentage losers.

Stocks that are making large-percentage moves like these are favorites among short-term traders because they can jump into these names and try to capture some of that massive volatility. Stocks that are making big-percentage moves either up or down are usually in play because their sector is becoming attractive or they have a major fundamental catalyst such as a recent earnings release. Sometimes stocks making big moves have been hit with an analyst upgrade or an analyst upgrade.

No matter what the reason is, when a stock makes a large-percentage move, it is often just the start of a new major trend -- a trend that can lead to huge profits if you time your trade correctly. Combine technical indicators with fundamental trends, discipline and sound money management, and you will be well on your way to investment success.

With that in mind, let's take a closer look at several stocks under $10 that are making large moves to the upside today.

Vasco Data Security International

Today’s Range: $7.25-$7.87

52-Week Range: $4.63-$14.72

Volume: 350,000

Three-Month Average Volume: 271,954

Shares of VDSI are soaring today after the stock was upgraded to buy from hold at Wunderlich.

From a technical standpoint, VDSI is gapping up big today with strong volume, and the stock is now starting to challenge its 50-day moving average of $7.59. Traders should continue to look for long biased trades in VDSI if this stock manage to close above the 50-day and near its daily highs.

If we get that action, then I would look for VDSI to challenge $8.50 to $9.18 (its 200-day) in the near future, as long as the upside volume continues to track in strong.

Velti

Velti (VELT) is a global provider of mobile marketing and advertising solutions that enable brands, advertising agencies, mobile operators and media companies to implement campaigns by communicating with and engaging consumers through their mobile devices.

At one point, the stock traded as high s $7.41, which also pushed it above some near-term overhead resistance levels at $7.06 to $7.13.

Traders should now watch for a sustained move and close above the 50-day and near the daily highs to trigger future upside. If we get that action today or in the near future, I would then add to any long positions once VELT takes out $7.73 with volume. A potential target on the upside if all of those levels are cleared is $9 to $9.50.
