THIS is a way to get rich. To get wealthy, you cannot be diversified. No wealthy person is diversified.
> To get wealthy, you cannot get diversified Sure, but not diversifying is also one of the most efficient ways to go broke. Which is something that diversifying will make much more difficult. Also, full baloney. I was not diversifying for many years and it indeed made me great money (thanks MSFT). But when I started getting spooked and diversified, guess what? I still ended up doing pretty well, even if it wasn’t on…
To me diversification goes against all logic because the rule #1 of investing should be that you as a investor KNOW what you are investing in. You can't tell me anyone investing in say S&P 500 has done extensive research on each every of the 500 companies. All they are hoping for is "hey, these are 500 biggest companies in the World, imma just put my chips here and hope for the best - history tells me that is probably safe bet."
On the other hand, you can do full-on research into a single or handful of companies and then put your chips there. You can't tell me that putting money in Magnificent-7 say 5 years ago was any riskier than putting money into S&P 500... and yet you could have gotten REALLY wealthy with the former and quite rich with the latter...
