Can AAPL get back to ATH in 4 years?

Mentally it’s tough to keep buying with non-stop red days. Here’s a long term perspective to consider.
$Apple (AAPL.US)$ is now down 30%, but a return to all time high means a 183/129 = 42% return. If you’re happy with an average annual return of 10%, then buying now means AAPL has 4 years to get back to ATH in order for it to be a good investment for you.
Obviously a faster return to ATH gives an even better average return. (I oversimplify the math a little by ignoring compounding)
A similar analysis on these blue chips shows that a return to ATH in,
$Microsoft (MSFT.US)$ : 4.5 years
$Alphabet-C (GOOG.US)$ : 5 years
$Amazon (AMZN.US)$ : 8 years
Would equate to an average annual return of ~10%.
If your time horizon is more than a few years, these are great times to be in the market.
