“We’ve been talking about the bond bubble with advisors for a year,” Adam Patti, chief executive at IndexIQ, said in the article. “Every time we see a market disaster, the phones ring off the hook,”

For instance, when the bond bubble bursts, investors could look at the IQ Hedge Multi-Strategy ETF (NYSEArca: QAI) or the ProShares Hedge Replication ETF (NYSEArca: HDG), which both track hedge fund strategies other than traditional beta indexing.

Other alternative ETF strategy providers include WisdomTree Investments, PowerShares and AdvisorShares.
