IVW tax-loss harvesting alternatives

iShares S&P 500 Growth ETF (BlackRock) tracks S&P 500 Growth. If you hold IVW 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 IVW during the 31-day wait.

Sorted by 1-year correlation of daily total returns with IVW (through 2026-10-16). Holdings overlap = sum of the smaller weight of each common stock, from issuer holdings files; “n/a” where the issuer does not offer a free download or for bond/international/commodity funds. Hover a value for its as-of dates.

Avoid as a replacement: same index as IVW

These track the same index (S&P 500 Growth). Buying one of them within the window is the classic “substantially identical” risk.

30-day wash-sale calendar for IVW

The window is 30 calendar days before and after the sale (61 days total, IRC §1091(a)). Buying the replacement fund right away is the point of a swap; the dates above are about buying back the fund you sold, or anything substantially identical to it.
