Big drops are normal for some funds. They matter because selling during a drop locks in the loss.
What does GSG hold?#
This fund does not own stocks. It holds futures contracts tied to the S&P GSCI, a broad index of commodities such as oil, gas, metals, crops and livestock, plus short-term cash-like holdings. Its value rises and falls with those raw material prices, and it sends a K-1 tax form instead of a 1099.
It tracks the S&P GSCI Total Return Index.
What is the GSG expense ratio?#
GSG charges 0.75% a year. An expense ratio is the yearly fee a fund takes to run itself. On $10,000, a 0.75% fee comes to about $75 a year. Of the 162 ETFs on Tactfolio, 2% charge more.
You never get a bill for it. The fund takes the fee out of its own value a little each day.
