Quants Beware ! Next 390 Mio Usd Desaster ?

Humble question to our QUANT community :

any chance we see today 25 standard deviation day or ????

 

no.

 

when computing stdev, like 25 devs or 7 devs or whatever, is there a standard period used (like 7 days, 20 days)?

 

I just observed VIX climbing 12 % today...that´s why I am asking...

 

Great, more risk free $$$ for me writing naked ES puts.

 

So, at which point of the day can we expect the RALLY ?

 

What is "390 Mio"?
