%%Does anyone know of a tool which compares ETFs to find other ETFs that are most correlated to it? For tax reasons / wash-sale rule, I can't buy a given ETF and want to find a substitute.
That's correct.Looks like the closest correlation to SMH is SOXX.
That's correct.
About a tool: I recall that in IB's TWS there is/was a tool to give a target (e.g. ETF, mutual fund) and then this tool comes up with a combination of other ETFs/mutual funds to replicate as close as possible that target. However, I haven't checked for several years whether the tool is still there.
