Tax-Loss Harvest Finder
Sell the loss, keep the exposure. For any fund, ranked stand-ins that track the same market — scored on a year of price correlation, holdings overlap, and fee — with a flag when two funds follow the same index and a swap could look substantially identical.
Correlation computed on ~250 shared sessions per pair · not tax advice — the flag is a heuristic, your compliance desk has the final word

RANKED BY CORRELATION, FEE, AND OVERLAP · “SAME INDEX” PAIRS ARE FLAGGED BECAUSE THE IRS HAS NEVER DEFINED “SUBSTANTIALLY IDENTICAL” — MOST DESKS TREAT SAME-INDEX SWAPS AS OFF-LIMITS AND DIFFERENT-INDEX SWAPS AS DEFENSIBLE
