Do ETFs face a liquidity risk?
Bogan Associates LLC made a name for itself in the passive investing community by warning about an ETF collapse.
The argument is pretty technically but, at its simplest, it argues that an ETF which has (a) a large number of short positions; and
(b) is subject to a large number of sale orders could not have enough cash to pay out all the investors (the more technical explanation is provided by Bogan Associates who explain how short selling can lead, in some situations, to more units than issued by the issuer itself).
John Heinzl is one of the many writers who have argued against Bogan Associate’s theory that ETFs can collapse.
What is interesting about Heinzl’s article is that Bogan’s highly technical piece appears to have made it to main street as iShares admits it fields calls daily about the possibility ETFs imploding.
