I apologize if this is redundant and has already been posted elsewhere. But I read this in a Bloomberg article just now and thought it was worth sharing. Tomorrow, a quarterly event known as "quadruple witching" is going to happen. From the article:
"Another day, another threat, on Friday: a quarterly event known as quadruple witching, in which mayhem is sometimes unleashed by the expiration of various futures and options contracts."
I'm not smart/experienced enough to understand the full implications of this in our current situation. But I looked over on wsb and many people seem to think it means a massive pump will happen in the last hour. Again, I have no idea. Something about MMs needing to (maybe?) hedge put options because of Red Mondays that have been typically happening. I'm too much of a novice to understand though.
Hope this helps someone out there. Good luck.
It's behind a paywall though. Here's a screen cap: https://imgur.com/a/D2ijW7X
PS. Also, the same Bloomberg article suggests that SPY has been holding the Christmas 2018 support at 2,351. We tested it twice this week and appeared to bounce off (well, went below a bit on Wed but eventually recovered). But who knows what next week will bring. Just FYI– hope this is useful to someone out there.
