Since your waiting period is long. Why dont you but the commodities like gold, silver and you may also consider the oil. Because all of these for sure will increase in the coming years because of the huge demand and low supply.
Split it between a few broad ETFs. Cheap to trade. Cheap to maintain. Mostly harmless and with zero rebalance work involved. => Hard to screw up.
Well the question was about investment. Plenty of trades on the short side, if you're nimble & like to get up early.
I sort of disagree. I mean, there have been plenty of instances where the small investor can blunder into a diversified bundle of assets (long), do nothing for 5 years, and come out looking like a champ. The end-of-the-world blow ups only happen about every 15 years, give or take, so, largely "all good" for the long little guy. On the short side though, while you look like a freaking super star when you nail it, I'm not so sure we're talking set & forget. Keen to hear your examples..
I totally agree, long term, trading stocks is best way to make more than just about anything as far as percentages while not actively working hard at it. Better quality of life. What I did long ago starting at age 21, I bought one 3br house each year and rented them out, letting others pay for them, I am now 56yo and still do this. You can trade up your account a bit and do the same. Is Peter Lynch in the game or did he fully step away? William J. O'Neil "Can Slim" method is interesting method that seems to do well from what I read.
