In the last couple of years I have been trying to educate myself in what concerns finance. I have put some money on some financial products (shares and ETFs) but I feel like I am playing the roulette sometimes. I have bought stocks of some companies that I know and they are doing ok but I think I would prefer to expand my investments with ETFs. I have been looking to ETFs related to industries that I think should have a bright future like robotics, renewables and water.
I currently own shares of ROBO and PHO ETFs. When I bought these I read a lot of stuff in those 'Best performing ETFs and bla bla' lists but I feel like it shouldn't be the best way to select investments.
Any tips on how to proceed? I am also thinking in investing in ETFs that track world economies like the Vanguard Developed World and Vanguard emerging markets. Any thoughts on that?
