This stock is trading up 7.6% at $36 in recent trading. Today's Volume: 2.30 million Average Volume: 952,560 Volume % Change: 261% Shares of CAVM are exploding higher today after the company reported stronger-than-expected fourth quarter results, and Stifel Nicolaus increased their price target and maintained their buy rating on the stock. From a technical perspective, CAVM is gapping up sharply here right above its 50-day moving average of $32.7 with monster upside volume. This move is quickly pushing the stock within range of triggering a major breakout trade. That trade will hit if CAVM manages to take out some near-term and past overhead resistance levels at $36 to $36.61 and then $36.67 with high volume. Traders should now look for long-biased trades in CAVM as long as it's trending above today's low of $34.10, and then once it sustains a move or close above those breakout levels with volume that hits near or above 952,560 shares. If that breakout triggers soon, then CAVM will set up to re-test or possibly take out its next major overhead resistance levels at $42 to $45.39.
