The Trailing Twelve Months Income Available to Common Stocks (TTMIACS) of the S&P500 is tightly correlated to the S&P 500.
TTMIACS has been declining since Feb-2015 when its 10-week moving average crossed its 40-week moving average to the downside.
Exiting the stock market according to this indicator would have avoided major losses in 2001 and 2008.
According to this indicator, a downwards potential remains in the S&P 500 with a possible low of 1660 in the next three months.
