The last 4 parabolic moves saw Apple's stock decline anywhere between -29 to -40% (from break of curve NOT high). My last analysis on Apple saw nearly a -32% drop. If history repeats itself, another windfall in Apple is in the making and another big score to come.
This is not a recommendation to buy or sell Apple. Before investing or trading, please do your own dues diligence or contact your financial advisor for guidance.
