IGV provides diverse exposure to the North American software industry. It caps individual security weights at 8.5% to provide more diverse exposure to a concentrated industry. The index redistributes its portfolio away from tech giants into smaller, more growth-oriented software companies. Canadian firms are included but make up only a small portion of the portfolio. It's a sensible approach for investors who want exposure to the software industry with subdued concentrations. The fund changed indexes on December 24, 2018. The new index is functionally identical but includes specific companies by name (Activision Blizzard, EA, Snap, Take-Two Interactive, and Zynga). These companies were reclassified into the new Communications Services sector at the end of 2018 and would otherwise have been removed from the fund. Stocks are reviewed semiannually in June and December, and weight capping are applied quarterly starting in March.
