Context
What happened: A report cites J.P. Morgan data on 60/40 stock/bond portfolios with periodic rebalancing, saying they recovered from drawdowns of 20% or more faster than the S&P 500.
Key numbers: S&P 500 up 116% and Nasdaq Composite up 156% over the last four years. Since 1988, the 60/40 portfolio recovered from 20%+ drawdowns in 11 months on average versus 24 months for the S&P 500.
Why it matters: The article says rebalancing forces buying stocks after declines, which it credits for faster recoveries, while noting bonds have more limited upside and can drag long-term performance.
