1) 30% DECLINE IN 3 MONTHS
Apple (NASDAQ:AAPL) tanked 30% in less than 3 months. Move like this has nothing to do with fundamental reasons (because nothing has changed fundamentally last three months), but mostly to do with psychological and technical reasons. Psychologically, investors are afraid of the overall market's health with volatility we've seen this year. Technically, AAPL was extended/overbought so investors are taking some profits while the chasers who bought at the top exiting their positions in panic hence the 30% decline in very short time. 
2) Rising 100SMA
I think this is important moving average to pay attention to as it has been served as strong resistance/support through out 2016 (see arrows). Today we are retesting it here for the first time since the late 2016.
3) RISING PIVOT/SUPPORT
Pure technical analysis right here; the rising pivot (blue arrows) and the rising support (red arrows). 
4) EXTREME OVERSOLD
Who could forget 2013 and 2016; according to my oscillator this is the level to buy and not sell (blue arrows) if you are a long-term trader/investor just like 2013 and 2016.
5) Rising-Channel Retest
Breakout-retest is a beautiful thing, because it strengthens the trend with viability. That's exactly what is going on here, we saw a breakout in 2017 and we are seeing a retest today. If we can sustain this level, AAPL is preparing to get into a whole another level to the upside.
