Hansen Medical ( HNSN) develops, manufactures and markets a generation of medical robotics designed for accurate positioning, manipulation and stable control of catheters and catheter-based technologies. This stock is trading up 8.9% at $3.53 in recent trading. Today's Range: $3.16-$3.56 52-Week Range: $1.90-$5.28 Volume: 745,000 Three-Month Average Volume: 595,587 From a technical standpoint, HNSN is starting to trigger a big breakout trade today now that this stock is moving above some major overhead resistance levels at $3.38 to $3.40 on heavy volume. Market players should now watch for a sustained high-volume move and close above those levels, and above the last major near-term overhead resistance at $3.68, to signal a much large move to the upside for HNSN. If we get that action soon, then I would target a spike higher back toward $4.20 to $4.46 in the near-term.
