Traders should now look for long-biased trades in VHS as long as it's trending above its 50-day at $11.07, and then once it sustains a move or close above $12.79 with volume that hits near or above 211,268 shares. If that breakout triggers soon, then VHS will set up to re-test or possibly take out its next major overhead resistance levels at $15 to $15.77. Keep in mind that any move above $12.79 will push VHS into new 52-week high territory, which is bullish technical price action.
