I do like the strategy of just putting 10% into something risky like BTC or single stocks. My problem with single stocks is; so you bought Nvidia in 2005, or Tesla in 2010 or so, Apple Microsoft etc, and you did well. What did you do with your losers? With a massive winner you may have wiped out those losers, but usually its the other way around. Its a lot of work and brains to spot fundamental changes within the company, especially without a team of PHDs and access that hedge funds have. Can you identify loss of market share before them? Do you know the CEO and management's life story? Can you predict the rise of future demand and growth for the companies? Big winning companies keep growing, the second that stops they are either a failure or the next boring stock underperforming indices. Some I know are great at this, but most have no edge and just see these big winners in hindsight. They don't see all the stocks that were all the hype and went to $0. If I was into this risk, I'd keep it simple and I'd stick with boring healthcare/providers and obesity drug companies. Boomers are aging and people will always need healthcare. The ETFs have always outperformed the $SPY. But for stupid me, its just $VHT $IHF and a little bit of biotech $IBB $XBI instead of single company risk.. Stay safe out there.
