Come on don't be ridiculous giving a straight forward no nonsense answer that makes sense. Throw me up a speculative news article or write me 2 paragraphs of why it happened after the fact.
There was no spike (down or up) in VIX at 1 PM on Tuesday. It was at 10 am when they announced rate cuts
It should be a rule that all times related to anything financial means Eastern Time, i.e. Wall Street. So by default everyone should adjust their clocks to it, not the other way around on guesswork.
Well as you pointed out his reference of a spike at 1:00pm doesn't make sense. Anyway let him respond
It is going to get even more confusing tonight, as the USA jumps ahead 1 hour on the clock for it's damned Daylight Saving time. I hate this shit. Which reminds me. Keep an eye out for abberant behavior Monday morning. I finally noticed last year that on the Mondays following the spring ahead or fall-backs, the markets seemed "different". Of course with this Corona stuff the effect, if any, may be muddled. But I can swear that clock changes seem to affect the market behavior for that first Monday following the change..
