If some (or all) options strikes get suddenly changed and made "
Non Standard (NS)",
then only current holders can trade it anymore...
And for the current holders it means there is no Bid/Ask by the MarketMaker anymore,
b/c the MM stops providing liquidity for such NS options anymore! Ie. the current holders are lost!
And this gets very much systematically abused recently, mostly with ETF options,
but recently also with options of
PACW -->
BANC.
These gangsters simply make a stock split and by this then declare the options as Non Standard (NS)...
IMO clearly a "Systemic Systematic System Error"...
