ETF Watch: The Inclusion Calendar

Field notes

ETF Watch separates the announcement of an index change from the later effective close, when tracking funds must own the incoming stock. Its historical view measures both the pre-inclusion run-up and subsequent performance, including returns relative to the index. The page reports a median announcement-to-effective interval of zero days across 364 additions, while its examples range from SNDK’s +1213.1% one-year result to TTD’s -76.8%.
