I see your point, but I disagree. When you quoted me you took part of it out of the context which was "look at Apple, it is making shit load of cash every year". Of course I meant that it is hugely profitable company. Now google "amazon profitability" and you will see yourself that it is kind of funny nowadays that the company has almost no net profits yet the shares skyrocket. With all fairness to Amazon though, they have tons of revenue from profitable businesses and they invest heavily into new and diversified businesses.
But when it comes to Netflix you need to consider that this is just one type of business and they either attract customers (growth) by low prices or costly programming, either way posting no profits. Should they decide to be profitable (and that's the goal of any business unless I'm missing something here) they would either have to raise prices or spend less which bears serious consequences. Add to that competitors that will react accordingly. So if you're not profitable now, don't expect to be profitable for years, then what the hell are we talking about?
Tesla is a wrong example. It's a cult stock and no more. The valuation of that company makes no sense at all. Any company currently on the market can bring the same product they plan to do. Just put in electric motor (which is a no-brainer to produce, unlike combustion engine) and the battery. Yes, the battery is a problem, but it is a problem for everyone and once solved it will be solved for everyone too. But competitors (at least some of them) have something that Tesla doesn't have, which is knowledge through years of continued R&D. Manufacturers like Mercedes, BMW, Audi bring tons of new features all the time and that's why we have the kind of cars today and not what we had 30 years ago. The car is more than a motor alone. This why when you read that Volvo plans to be making EV only cars in a few years, it's not the "oil" that should worry the most but folks that buy Tesla shares, as Tesla doesn't have anything that other majors don't have, yet they have a lot that Tesla doesn't.
