S2007S told someone to liquidate all their equities to cash late spring 2009. He also claimed a 40-60% crash was "imminent" when the SPX was roughly 1950 in 2016. Of note as well is he's calling for a far bigger drop then the worst of this one so far.
I highly doubt markets ever get low enough that you do serious buying. You were telling people to sell late spring 2009.
