Strategy: Precious metals
Funds that hold physical gold or silver in vaults, or the companies that mine it. Physical-metal funds that hold the same bullion differ mainly in fee, share price and trading liquidity, while miner funds behave like leveraged equity bets on the metal price. None of them pay a dividend from the metal itself.

Metal prices can fall for years with no income to cushion the decline, and gains in physical-metal funds can be taxed at the higher collectibles rate in the US.

Performance
Total returns with dividends reinvested, from the adjusted closing price series. $10,000 invested on Oct 20, 2021 would now be worth $22,790 in IAU and $23,010 in IAUM.
