A few take-away points:
1. The benefits from diversification based on historical correlations is great only if correlations don't change during sudden move;
2. The collapse of LTCM is not a problem of flight-to-quality, rather, it's the problem of everybody trying to get out of the same trades LTCM had.
3. We need to seriously deal with counterparty risk, and work out a solution. Otherwise, the too-big-to-fail problem will haunt us, always.
