My thoughts on this and what i seeAC is having trouble because it meets with the RSI line from 63 to 79 and anything over 70 is over bought and AC just drops below and keeps trying to stay above or go back to it.. so right here people are taking more profits than people buying in at 12 and it stabilizes in 11.90s -11.80s because people are holding and anticipating new highs. but the stock dips because of bears and profit takers and close to over bought zone. that's why i look to sell at the high and buy lower.
