RE:RE:Morgan stanley warrant knock
MSE had a mini futures security that had a knock out level of 2,49SEK. At that price the warrant is terminated and you can't trade it anymore. By driving the price below that level they made themselves a ton of money. That's the spike today, the volume is from all the other algos going bananas as they try to adjust to a trading pattern they are not designed to handle.
But that's just my guess as always and not to be taken as facts.
