ETF Supply vs Demand
Proving once again that Wall Street is more of a product manufacturer than a professional services provider, Jason Zweig highlights the proliferation of new and exotic Exchange Traded Funds (ETFs) and his expectation that many won't survive.
To me, this is an example of Wall Street creating products that they think they can sell to investors instead of delivering products that are in demand and/or will prove to benefit investors over the long term.
