MADISON, Wis. ( Stockpickr) -- Professional traders running mutual funds and hedge funds don't just look at a stock's price moves; they also track big changes in volume activity. Often when above-average volume moves into an equity, it precedes a large spike in volatility.Major moves in volume can signal unusual activity, such as insider buying or selling -- or buying or selling by "superinvestors."
Average Volume: 1.77 million
Volume % Change: 418% Shares of VRX jumped modestly higher on Wednesday after the company said it raised $2 billion in an offering of its common shares, which will be used to help fund its planned $8.7 billion acquisition of global eye-care company Bausch & Lomb. >>3 Health Care Stock Under $10 to Watch From a technical perspective, VRX bounced higher here right above some near-term support at $82 with heavy upside volume. This move is quickly pushing shares of VRX within range of triggering a near-term breakout trade. That trade will hit if VRX manages to take out some near-term overhead resistance at $88.67 with high volume. Traders should now look for long-biased trades in VRX as long as it's trending above some key near-term support $83.86 and then once it sustains a move or close above $88.67 with volume that hits near or above 1.77 million shares. If we get that breakout soon, then VRX will set up to re-test or possibly take out its next major overhead resistance levels at $92 to $92.50. Any high-volume move above those levels will then put its next major overhead resistance level at $96.25 into range for shares of VRX.
