Horizon Therapeutics (HZNP) shares are now above VWAP off its record highs and worked out of a downtrend after basing in a high-volume zone. HZNP is also seeing weekly RSI break above 50 and MACD nearing a bull crossover buy signal.  HZNP does have 5500 May $100 short calls in open interest so market maker hedges may keep it contained under $110 through expiration.
