Lack of bid offer on ACI call 19 April expiration

[arturo100]

MM don't hedge each time they trade cause their positions are netted.
They make their money from buying at the bid and selling at the offer ('the spread').
And don't worry, they'll make money even (or especially!!) if they don't offer you a good price.
If you don't want to trade against MM (or minimize it), you shouldn't trade 'unliquid' options.

If they do an overall hedging, there would be no reason to expose a bid below parity. If they didn't hedge, they are already losing money because I bought at 0.8 and the intrinsic value, which I could get by exercising the call, is already well beyond that.
