The First Trading Day of the Month

So far this decade, the market hasn’t done very well except for one small phenomenon—the first trading day of the month. Through yesterday, the S&P 500 is down 39.5% for the decade. But the market has returned over 21% on the first day of the month (neither figure includes dividends).
What’s interesting is that first days of the month occur less than 5% of the time, so sitting out the rest of the time would have been a smart strategy. How’d you like a job that probably improved your performance if you took over 20 days a month?
