In his latest blog, Matt sings the praises of ETNs and argues that the risk of losing money is “vanishingly small”.

Matt’s argument is that “most ETNs offer daily redemptions at net asset value, meaning that (even ignoring the quoted market) an investor of size (50,000 shares in the case of iPath ETNs) can sell out of the product within 48 hours and get the full net asset value of the note from the issuer.”

In other words, even if you become concerned about the credit risk of the issuer and there is insufficient liquidity in the secondary market for you to trade, you can get out of a position by selling it back to the ETN issuer.

I agree with Matt that the tax treatment of ETNs gives them a huge advantage for US investors (ETNs are taxed at long-term capital gains tax rates and only on a deferred basis
