Now my little thought experiment: Why should I limit myself to three ETFS when I could spread the whole thing much more widely? I have also thought about something like this (with smaller sums, of course):
Even if some disagree, sector ETFs are not a slice of the pie. It's just like a casino. You bet on a sector and hope to achieve an excess return. It can go well, but it can also go wrong. If you're aware of that, then it's okay. And why shouldn't you limit yourself to just three ETFs? First of all, what is your goal with more than three ETFs? You want to switch for a specific reason. Is that still the case? Do you want to go to the trouble of weighting the individual ETFs depending on what's going well or badly?
