GM!
Not sure how knowledgeable you are about stocks and derivatives, if you aren’t I would suggest avoiding those leveraged plays on MSTR unless very bullish short-term. If you know your stuff, just ignore me lol.
MSTX and MSTU seem to track worse on the downside because of the options decay. You might see that accelerated on expiry.
Pre-market is also trick, maybe liquidity is low for them?
MSTR is volatile enough for me but if I want additional volatility (rarely) I go to the options chain directly on either MSTR or IBIT.
