I really wonder about Barclays and other European outfits such as SG. I am sure governments would step in in case of problems there. But the other day I was listening to Brinker and he reminded listeners that there is no fund protection with mutual funds, I never really worried about this and mistakenly assumed SIPC would play a role but SIPC protects against the brokerage failure, not the failure of a fund company.
I also wonder about the short Proshares , they use swaps to short, but what about the counterparty risk there ? There are already someproblems with the short sale ban as I understand as they stopped issuing new shares for their short financial fund. Just wondering about the risk of having such fund mechanism blow up on you , not that yopu would lose all your money but your actual return would be very different than expected.
