There is no question about the high flying stock was hit mercilessly April high was printed, sense then, the stock had two classic 25% declines in a similar fashion, today's 26% jump from at and around 52WL was not unusual, but someone scared the shorts and they rush to the exit before the earning. StdEV stands as of yesterday 2.9. Earning is scheduled to release end of the month, and today's huge volume may suggest extreme volatility ahead of us. Another indicator Put/Call ratio stands 0.50 which means every one put there is 2 calls..option traders are bullish in the short term. u can calculate OTM put/call ratio is seems reversing today..the sizzle index is its highest today 7 which also is extreme.
