A Wheat ETF Teaches the Meme Crowd a Lesson the Hard Way
Commodity prices have soared the last two weeks as a result of the Russian invasion of Ukraine, drawing novice investors looking to make a quick buck. Many are already getting burned by their lack of knowledge.
Investing in commodities is more complicated than investing in stocks. In commodities, all the action occurs in the futures market because there aren’t any liquid markets for things like spot oil, gas or corn. Then there’s the margin system — to trade commodities futures you must deposit some initial margin into an account and then you are subject to the ongoing vagaries of adhering to margin requirements. But most of the investing public doesn’t want to deal with all that, so they just gravitate to the growing number of exchange-traded funds tracking single commodities or baskets of commodities. Here, too, the risks are different than with an ETF that owns stocks.
This week we learned that the Teucrium Wheat ETF – ticker WEAT and the only U.S. ETF tracking wheat - was unable to handle the volume of cash that was flowing into the fund from investors looking to profit from a record rally in the price of the grain. WEAT is a special kind of ETF known as a commodity pool, and unlike normal ETFs it needs regulatory approval to create new shares beyond a certain threshold. But so much money flowed in that the threshold was exceeded, and creations were suspended, which led to the ETF’s share price diverging from the price of wheat. In other words, the ETF ended up trading at an unusually large 9% premium above the fund’s net asset value. So, anyone who bought the shares significantly overpaid for the underlying assets.
The United States Oil Fund LP – ticker USO – received a lot of unwanted attention in 2020 when oil prices briefly went negative. USO’s shares didn’t go negative, mostly because it rolled its futures exposure out to longer maturities, but got admonished anyway by the U.S. Securities and Exchange Commission for not adequately disclosing its actions. Even before that episode, people had complained about USO for years because of the high costs associated with rolling its futures contracts to longer maturities was eating into the returns of the fund.
The problem with all this is that futures investors are perhaps more sophisticated than retail stock investors, and are familiar with all the risks inherent in futures (daily trading limits, roll/carry costs), while equity investors are not. Also, the structure of commodity ETFs is such that they take most of the leverage out of what one might get in the futures markets, with their tiny margin requirements, leaving their shareholders with all of the risks and none of the returns. Plus, many futures markets trade around the clock (wheat trades about 18 hours a day). If you have a position in a commodities ETF and something happens overnight that effects prices, you are stuck until 9:30 a.m. New York time before you can do anything to mitigate your risk.
