I don't understand the point about selling and rebuying options, Nico, given that they'll be adapted accordingly, what's the benefit? My 4x June 2022 $1250's will become 20x $250, still ITM, so what's their point? My $3500's become $700's - if anything they'll be far MORE liquid after the split.
I don't know the potential timing yet - as late as possible, even in after-market on the final possible day, then pre-market the next. Don't know, lots of confusion around what happens between 21st and 28th August IMO.
Hopefully we'll get the clarification that it's a non-event and such scenarios won't be necessary.
Remember the Euro? Between 1999 and 2001 we already had the euro only it's physical appearance was in the form of guldens, marks, francs. Same thing will happen here. You buy one old share, you get 5 new shares. It's the essence of bookkeeping, change something on the left page, make the contrary change on the right page and your balance will stay in balance.
