Re:Too bad (Score 5, Informative)

I'd tell the firm "too bad". It shouldn't be up to the NYSE to make sure companies don't do something stupid. Back in time a ways, when someone tried to game the system and then failed hard they would be ignored and forgotten. Now, with bailouts and do-overs and participation trophies, we ignore hard working americans who don't expect handouts and reward those who don't want to take responsibility for their actions.

Actually, NYSE did tell them exactly that.

Knight is on the hook for the full 440mm USD loss. NYSE stuck them with every single trade that they transacted during the particular time span.

And before you spew the bailouts/ do-overs/hard working american rhetoric, let's actually review the facts related to the topic on hand.

-Knight is a market maker. Their sole purpose on NYSE to ensure liquidity and make money. They do it by actively stepping in to sell and buy particular securities. There is nothing there that "games" the system.
-They rolled out a new application mid week and apparently turned it on without fully testing it causing a huge spike in volume
-The algorithm, rather stupidly, bought high and sold low.
-NYSE actually called within 30 minutes Knight to inform them that they might be accidentally executing incorrectly
-Knight basically ignored the warning and let the algorithm run for a full hour.
-End of the day, Knight is on hook for the entire loss. Not because it was a "mistake" but because these are all legitimate trades with legitimate counterparties and didn't violate any rules.
-Nyse has stated that and has said there would be no further appeals allowed on the issue.
