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

    Quantum Fuel Systems

    Quantum Fuel Systems (QTWW) is an integrated alternative energy company engaged in the development and production of advanced clean propulsion systems, and renewable energy generation systems and services. This stock is trading up 2.7% at $1.54 in recent trading. I also featured it a week ago in another look at stocks under $10 moving higher.

    Today’s Range: $1.45-$1.95

    52-week Range: $1.02-$10.80

    Volume: 393,000

    Three-Month Average Volume: 163,850

    Shares of QTWW are trending higher today after the company reported second-quarter revenue that hit $13 million, up 233% from the same quarter last year.

    From a technical standpoint, QTWW tagged its 200-day moving average of $1.92 today before pulling back to its current price near $1.60 on solid volume.

    Market players should now watch for the next buy point to trigger once QTWW can sustain a high-volume move and close back above the 50-day and then above some near-term resistance at $1.96.

    Siga Technologies

    Siga Technologies (SIGA) is engaged in the research, development and commercialization of products for the prevention and treatment of serious infectious diseases, including products for use in defense against biological warfare agents such as smallpox and arena viruses. This stock is trading up 33.2% at $2.45 in recent trading.

    Today’s Range: $1.78-$2.54

    52-week Range: $1.84-$15.66

    Volume: 1.7 million

    Three-Month Average Volume: 721,633

    From a technical standpoint, SIGA has hit a major breakout today now that the stock has moved back above some past overhead resistance at $2.16 on huge volume. Market players should now watch for a sustained high-volume move and close back above its 50-day moving average of $2.80.

    If we get that move soon, then this stock could setup to re-test some previous resistance at $3.25 to $3.58 in the near-term.

    SeaChange International

    SeaChange International (SEAC) is engaged in the delivery of multi-screen video. Its products and services facilitate the aggregation, licensing, storage, management and distribution of video, television programming and advertising content. This stock is trading up 12.5% at $7.85 in recent trading.

    Today’s Range: $7.01-$7.99

    52-week Range: $6.92-$11.66

    Volume: 116,000

    Three-Month Average Volume: 127,856

    Shares of SEAC are ripping higher today after the company reported net income for the third-quarter of $400,000, vs. a loss of $2.9 million in the same quarter last year. Revenue for the quarter also grew by 9% to $53.4 million from $49.1 million in the same quarter last year.

    From a technical standpoint, SEAC is quickly approaching a breakout trade if the stock can manage to sustain a high-volume move and close above some past overhead resistance at its 50-day moving average of $8.07 and $8.22. At last check, the volume isn’t there yet, so watch to see if the stock can close strong on volume that registers near or above 127,856 shares.

    A high-volume move and close above those levels should set this stock up to re-test $8.88 to $9.14 (its 200-day moving average) in the near future.

    Smith & Wesson

    Smith & Wesson (SWHC) is a global provider of products and services for safety, security, protection, and sport. This stock is trading up 11.4% at $3.71 in recent trading.

    Today’s Range: $3.34-$3.72

    52-week Range: $2.29-$4.06

    Volume: 1.6 million

    Three-Month Average Volume: 424,402

    >>Stocks Rising on Unusual Volume

    Shares of SWHC are ripping higher today after the company reported a smaller net loss due to improvements in its security division, which it is trying to sell. (I included Smith & Wesson in a recent list of earnings short-squeeze plays.)

    From a technical standpoint, SWHC is just quickly approaching a big breakout if the stock can manage to sustain a high-volume move and close above some past overhead resistance at $3.66 to $3.67. The volume today is already well above the average volume, so traders should look for a strong close above those levels.

    If we get that action, look for this stock to make a run at its next significant overhead resistance levels at $4.05 to $4.20.

    SuperMedia

    SuperMedia (SPMD) is a yellow pages directory publisher in the U.S. SuperMedia offers online advertising solutions. The company sells advertising solutions to its clients and places their advertising into its portfolio of advertising media. This stock is trading up 7.8% to $2.34 in recent trading.

    Today’s Range: $2-$2.45

    52-week Range: $1.16-$12.63

    Volume: 141,000

    Three-Month Average Volume: 84,411

    From a technical standpoint, SPMD is quickly approaching a big breakout if it can manage to sustain a high-volume move and close above some past overhead resistance at $2.41 to $2.66. Volume today is already well above its three-month average of 84,411, so watch for a close at least over $2.41.

    If we get that action, then this stock could easily re-test its 200-day moving average of $3.61 in the coming days or weeks.

    Imperial Sugar

    Imperial Sugar (IPSU) is a processors and marketers of refined sugar in the North American Free Trade Agreement (NAFTA) region. This stock is trading up 6.8% to $4.87 in recent trading.

    Today’s Range: $4.63-$4.94

    52-week Range: $4.36-$25.68

    Volume: 128,000

    Three-Month Average Volume: 332,288

    From a technical standpoint, IPSU is starting to find some buying support at $4.36 to $4.54, following the stock's huge drop from its August high of $25.61. The next buy point on this stock will trigger once it moves back above $5.25 to $5.50 on heavy volume. Look for volume on any move over $5.25 to $5.50 that tracks in close to or above its three-month average volume of 332,288.

    If we get that action, this stock should easily test its 50-day moving average of $6.06 in the near future. Volume so far today is very weak, so look for that to improve dramatically if you’re bullish on IPSU.

    Avatar Holdings

    Avatar Holdings (AVTR) is engaged in the business of real estate operations in Florida and Arizona. This stock is trading up 12.3% to $7.05 in recent trading.

    Today’s Range: $6.42-$7.05

    52-week Range: $5.80-$22.74

    Volume: 39,000

    Three-Month Average Volume: 56,969

    Shares of AVTR are soaring today after the company announced it sold 373 acres in Orange County’s Horizon West area to a New Jersey investment group for $16.25 million -- down from $4 million six years ago.

    From a technical standpoint, AVTR is very close to triggering a major breakout if the stock can manage to sustain a high-volume move and close above some near-term overhead resistance at $6.78.

    Traders watch for a move over $6.78 on volume that’s well above 56,969 shares. If we get that action soon, then this stock should setup to re-test its 200-day moving average of $8.11, or possibly trend much higher towards $9 in the coming days or weeks.

    Hansen Medical

    Hansen Medical (HNSN) develops, manufactures and sells generation of medical robotics designed for accurate positioning, manipulation and stable control of catheters and catheter-based technologies. This stock is trading up 8.4% to $2.46 in recent trading.

    Today’s Range: $2.27-$2.54

    52-week Range: $1.26-$5.28

    Volume: 217,000

    Three-Month Average Volume: 789,380

    Shares of HNSN are moving noticeably higher today after the company said it has secured a $30 million debt facility through Oxford Financial and Silicon Valley Bank. The proceeds from the financing will be used for general corporate purposes.

    From a technical standpoint, HNSN is bouncing off of some previous support zones at around $2.25 here. This is an area that buyers have been jumping into the stock for the past month or so.

    Market players should watch for the next buy point to trigger once HNSN can make a sustained high-volume move and close above some near-term overhead resistance at $2.50 to $2.73 (its 50-day). Look for volume on any move over $2.73 that tracks close to or above 789,380 shares.
