1) they are lying to you. Look at how much the stock has traded, Its alot but its nothing compared to how much SPY trades in a year. There just wasn't' anywhere near enough trading volume to make an entire year in one week even if they participated in every trade that Gamestop had this past week.
2) they lost money last year so any profit beats last year's pnl?
I’m in the industry. I stand by what I said:)
You said something that was flagrantly wrong, I’m just trying to help correct you.
Average PnL per share traded for a firm doing okay is about $0.001. A decent size firm might do 4% of ADV. Tape A trades about 1.5 billion shares per day. That’s 21 million annual trading revenue.
GME traded 1 billion shares in the past week. PnL per share has been averaging close to $0.40. At 6% ADV (HFT market share spikes during volatile periods), that’s 24 million in revenue.
I can tell you're in the industry because you say pnl instead of p&l haha.
