A portfolio composed of 60% SPY, 30% AGG, and 10% XLRE is predicted to yield an average 9.5% annual return, doubling capital in 7.5 years.
"put it all together this way that 60 301 portfolio gives you the higher returns but also the safety from that stock market roller coaster and an average 9.5 5% return a year it's more than double what you got from just bonds but not as risky as going all in in stocks and doubles your money in just 7 and a half years"
