I don't have a good way to look that up, but nothing like that made an impression on me... so I'm thinking not. Traders should not fear the "black swan" event. Should have reasonable plays with stops in place. However, nobody is safe from the "lightning bolt", and especially overnight. That said, nothing like that has happend to the markets since I've been a player. (Has happened to individual stocks, of course, but that's different.)
Reagan formed the PPT after Oct 19th 1987... Along with Collars/ Circuit Breakers to allow the Troops/PPT to flood the Market with Liquidity & Stem the momentum of Free Fall. Limit downs were hit Late 90`s Asain Contagion, LTCM, Argentina, as Iv`e traded thru those exciting times.... but we`ll never see another Gusher like Oct 19, `87! Too much Gov`t intervention.
I just think we are going down further and am starting to wonder if we give back all of the ‘ Trump Gains” starting in 2017. Thats brings the dow in the 18000’s.
