When Apple's stock has had a big correction it has always reconnected with its 15 QMA/200 WMA/200 WEMA.
Reconnects with the 200 Weekly MA/200 Weekly EMA: 2008, 2013, 2016, 2018 Reconnects with the 15 Quarterly (3 Months) MA: 2008, 2013, 2016, January 2019.
Indexes & ETFs etc. are now so concentrated in/heavily weighted for Tech stocks that if you can call just 1 mega huge Tech Stock like Apple, you can probably call the direction & vague magnitude of the move that will happen in the S&P 500 & the NASDAQ.
My target of $180 is sandwiched right between the 200 Weekly MA & the 200 Weekly EMA.
