Based on data reported by the Federal Reserve Flow of Funds Reports, which have been released on a Quarterly basis since 1952.
I have formulated an Index based on flows involving Mutual Funds which I call the Mutual Fund Panic Index.
Basically what the Mutual Fund Panic Index shows is that when the total value of Equities held by Mutual Funds decreases by
18% (black line) on a Quarterly basis significant Market Bottoms have occurred
since the early 1950's as the chart below shows.
