Splitting your money across stocks, bonds, real estate and cash is the decision that drives 90% of your long-term return. More than picking the right ETF, more than market timing. Before hunting for the 'right stock', set your allocation.
Four allocations dominate the literature and real-world portfolios. Each one matches a different time horizon and a different pain threshold. Find yours below.
At 30, 80% in stocks. At 50, 60%. At 70, 40%. Logic: the younger you are, the better you absorb a crash, because you have time to erase it. A starting point, not a truth.
Same starting capital ($50,000), same contributions ($500/month), 25-year horizon. With 100% stocks (10%): ~$1,270,000. With 60/40 (7.5%): ~$760,000. Difference: ~$500,000, about a 6-year head start toward FIRE. The flip side: in 2008, 100% stocks lost -38% while 60/40 only lost -22%.
Copying an allocation without matching your horizon and risk tolerance often leads to panic selling at the worst moment. A mathematically optimal allocation that is behaviorally unbearable is still a bad allocation.
Accumulation phase (before FIRE): 80/20 or 90/10 to maximize growth. Transition phase (5 years before FIRE): start gliding toward 70/30. Decumulation phase (after FIRE): classic 60/40, with 2-3 years of cash to absorb crashes without selling.
