Yet Knight Capital's share price never recovered. Say instead of KCG it was JPM, operating without the usual risk concerns because they've got assurance from the government of support. Should investors or taxpayers be okay with such an "internal issue" destroying part of their net worth? And wouldn't a too-big-to-fail company have a broader impact on the entire market if such a think were to happen? It's kind of the whole concept behind too-big-to-fail that they would.
