I personally have 50% going into SPY DCA then a bunch of other bets. Some of them have outperformed SPY, certainly in the bull market. We'll see how they do over 20 years though.
I've actually outperformed SPY with my personal bets, both over the last 10 years in general, as well as over the last 2 years (including this bear market).
But this is play money, not serious money. The bulk of my money is SPY/VTI + various Bond funds. I'm holding short duration and ultra-short duration and even Money Market for the near future, giving an eye to expectations from the Fed / interest rate hikes before jumping back into long term bonds.
