The thing that's interesting is that Goldman is known to have a long view on their businesses. for them to get out is saying they don't see the business having long term potential.
If they cannot make money trading options how about us retail traders? Maybe there are not enough of us? Should I follow them and get out of trading options?
They can't pick their trades as a MM and have huge technology costs. Two advantages you have that they don't. Your transaction costs may reflect the benefit of some rebate -they're the guys paying it.
Probably $300,000 - $500,000 in fixed costs to be a size MM today. The CBOE's old member's lounge now has a coffee bar. Nice touch. Markets evolve. Enough of the big firms quit MM and that could open up more opportunity for the mid-size and smaller MM firms.
Short answer: No. Long answer, MM can be a dream job. If I have a do-over career, I may want to be one.
That sounds low. I would guess upwards of a buck. The colo fees alone are going to be a few hundred. No you do not
Nope, but you should learn where they target profits. You can figure out a lot of future price movement knowing this.
