The last day of May has had a very modest positive bias, but hasn't been consistent enough to bank on. It was very positive prior to 1970, was mixed from there through the 1990's, then was positive 7 of the last 10 years.
Holding through the first two days of June fared quite a bit better, especially in current decades. Since 1974, the S&P showed a positive return during these three-day stretches 74% of the time, averaging just under +1%. 16 of the last 20 years were positive during this period, though 2008 failed to follow through on it. |
