A solid year: With a week to go, the S&P 500 index is on track to return about 30% this year.
A party next year too? The average annualized volatility during the 22 years following a 25%-plus gain is lower than the index's historical average since 1928.
Staying power: Since 1985, the S&P 500 has returned 25%-plus eight times. In seven of the following years, the index ended in positive territory.
Calmer outlook? A year ago, the CBOE Volatility index futures curve was much steeper.
