I don't want to brag, but buying ASML stocks was probably the smartest financial decision in my life.
Also, AMSL & AMAT aren't competing in some areas. AMAT provides tooling & services that assist ASML.
In the long term you don’t think the stock price is a function of a company’s success? Surely while a a company does very well financially and the financial outlook is very good, the stock price would be higher than when the fortunes change?
That’s because there’s no guarantee the company will thrive in the long term, nor that you didn’t overpay to begin with. That does not change the fact that share price is a function of the business’ financial success.
