8 Stocks Leaping on Unusual Volume

Alnylam Pharmaceuticals (ALNY)

This is a biopharmaceutical company developing novel therapeutics based on RNA interference, which is a naturally occurring biological pathway within cells for selectively silencing and regulating the expression of specific genes. This stock is trading up 5.1% at $18.93 in recent trading.

Today's Volume: 396,000

Average Volume: 273,855

Volume % Change: 217%

Shares of ALNY are trending higher today after Piper Jaffray upgraded the stock to overweight from neutral.

From a technical perspective, ALNY is trending higher here right above its 50-day moving average of $17.11 and above some near-term overhead resistance at $18.92 with above-average volume. This move is quickly pushing shares of ALNY within range of triggering a major breakout trade. That trade will hit once ALNY manages to clear its 52-week high of $21.38 with high volume.

Traders should now look for long-biased trades in ALNY as long as it's trending above today's low of $18.21, and then once it sustains a move or close above $18.92 to $21.38 with volume that hits near or above 273,855 shares. If that breakout triggers soon, then ALNY will set up to re-test or possibly take out its next major overhead resistance levels at $23 to $25. Keep in mind that any move above $21.38 will also push ALNY into new 52-week high territory, which is bullish technical price action.
