"Prices have almost doubled in the past 24 hours but are still well below the pre-sanctioned levels," said Edward Cowen, CEO of Winterbrook Capital, who has co-invested in a fund to buy Venezuelan debt. Cowen added that a return to Venezuela's regular weighting on global indexes like JPMorgan's would give the prices further support. "I think the market was caught by surprise as the ban on secondary trading of bonds was not expected to be removed this early in the negotiation," said Armando Armenta, senior economist for global economic research at AllianceBernstein. Small funds and investors outside the United States had looked to increase their exposure to Venezuelan bonds on the expectation of debt renegotiations.
