Deutsche Bank Debunks 'Sell in May': S&P 500 Buy-Hold Beats It in 8 of Last 10 Years

Deutsche Bank's 'Myth Buster' latest dismisses 'Sell in May and go away', finding it beat S&P 500 buy-and-hold in just 22 of 53 years and underperformed in 8 of the last 10. Story started April 27 with BofA noting May-Oct avg 2.4% vs Nov-Apr 5.2% since 1928, but June-Aug strong at +3.3% and weakness only Aug-Oct (-0.02%). April 29 added Signal (double-digit May-Oct gains in 4 of 6 years; 6.1% avg from ATHs, 85% positive) and MarketWatch (up 25 of 33 periods since algo shifts). Consensus favors holding or tactical plays near highs over seasonal selling.
