It's been an interesting time to be an index nerd since Vanguard went on the index-change warpath with its most popular ETFs .
And there are some significant lessons to be learned in analyzing investor behavior since the changes were announced.
To recap, back on Oct. 2, Vanguard started the fourth quarter of 2012 by announcing it would be migrating 22 index funds-of which 18 are available as ETFs-to new indexes. It will move away from MSCI indexes and organize the funds around CRSP and FTSE benchmarks.
At the time, we posted numerous articles and blogs analyzing what we thought the long-term effect would be on investors.

Along the way, we presented two webinars on the topic, one outlining the MSCI-to-FTSE switch and one documenting the logic behind the new CRSP U.S. Equity indexes. We also presented a counterpoint argument, talking with MSCI and iShares about the MSCI index series, the long-standing favorite in the international space.
