Probably oil stocks, or gold stocks. If anyone had the answer to that, ever one would be doing it. Even Warren Buffett buys and sells, he doesn't buy and hold.
Well, considering the last 10 years have made investors ZILCH...the next 10 years may be good or more of the same. There is no magic formula and if anyone says something else, they are lying.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
