1) No idea why I started at 2015, just copy pasted from a previous article I wrote. But good point, I'll take a better look at the wider data at some point.
2) Yeah, stock price. That's what we are talking about right? We aren't talking about the price of cheese.
1. From 01/01/15 through today Apple's stock is the second-best performer in the group of stocks you listed.

2. Companies can't control their stock price - they can only control how well they execute their business. On that measure Apple is the #1 company of the group you listed. The market-assigned P/E for an industry and/or company varies on lots of factors, most again of which are outside of a company's control.
 
On the metric of between 2015 and the end of 2021, the entire tech sector has been on the greatest bull run in history, with most big tech stocks multiplying their stock price by many times over in this time (AMD x40, Amazon x10, Microsoft x7, Netflix x6.5, Apple 5.5x, Google 4.5x, Facebook 3x, Intel 2x). Apple hasn't even been close to the standout performer in this boom, the've been quite average at best. Even Microsoft has outperformed Apple.

During that time, bois have been crowing about how wonderful Tim Cook has been, sending Apple stock to the moon. All of those bois have oblivious to the fact that Apple has actually been middling to underperforming in the sector.
It's funny, you know. Apple likely has the lowest margins of all the aforementioned companies, and it's the only one being singled out for price gouging. :p
