SOXX tax-loss harvesting alternatives

iShares Semiconductor ETF (BlackRock) tracks NYSE Semiconductor Index. If you hold SOXX at a loss, these ETFs track a different index, which generally makes them less likely to be considered “substantially identical” — while still moving closely with SOXX during the 31-day wait.
