it seems they may have damaged LFWK substantially. I guess that's very difficult to quantify, but sljb is strong enough to put a serious whooping on them, but my point is that they never borrowed the shares. who do they return them to? I guess if a federal margin call is imminent, then they won't wait to cover because it'll be a lower price the sooner they do it. How does a fed margin call come about?
