There's a third strategy of "index minus bullshit stocks" where you would include both INTC and AMD stocks for risk hedging, but would leave out things with questionable sustainability like Uber and Netflix that otherwise made it into the index due to the speculative value.
More or less. Of course, I am advocating to leave out any company where it does not fit this criteria: " are generating a lot of cash and a lot of profits, have a moat/USP/technology advantage, and are at the forefront of where the world is headed in terms of trends, or at least are following a sustainable trend".
On other hand it also avoids Tesla when it inevitably crashes to same ballpark as other automotive companies... No I really believe it is nothing special and will eventually come down.
