And if stock price is directly correlated with profitability again how does that relate to Uber and Lyft?

Alternatively, how does that explain Microsoft under Ballmer? Revenues and profits went up dramatically during his tenure but the stock price stagnated for years.

If stock price was directly correlated to profitability or business viability, Apple wouldn’t have such a low multiple compared to some of other tech darlings.

Its not directly related but profitability is one of main factor another factor is future earnings which should answer your doubt about Microsoft and Apple.
