Key Points:
- Rare S&P 500 feat achieved to end last week. +15% gain over 8 weeks has only occurred in 33 prior weeks, or about 1% of all weeks since 1970.
- Like the Russell 2000 >20% over seven weeks (see prior week commentary), forward returns are very strong in past instances.
- Most instances were bunched together in eight periods, Q2 2020, Q1 2009, Q4 1998, Q2 1997, Q1 1991, Q1 1987, Q4 1982, and Q1 1975.
- Of these eight, only Q1 1987 had poor forward returns.
- Individual cases included Q4 2002, Q4 2001, Q2 1980, Q1, 1976.
- Of these Q4 2001 and Q1 1976 had poor forward returns.
- Also last week, the S&P 500 closed 6% and 9% above 10/40-WMAs. This has occurred 65 prior times, or about 2% of all weeks.
- Forward returns are more mixed here, but overall still fairly strong.
- No surprise, but if the first four are positive, then the forward 26/52-week average is higher. If the first four are negative, the 26/52-week returns are lower.
