HART targets global firms that are positively rated for health standards reflecting the initiatives of the American Heart Association. This includes companies involved in curing heart diseases or helping limit cardiovascular risks by adopting a healthy lifestyle. Although companies of any capitalization from both developed and emerging economies are eligible for inclusion, the fund excludes countries believed to have oppressive regimes. The fund also has exclusionary screens for controversial activities, such as those involved in vices, weapons, animal testing and GMOs. Companies that make the cut receive an ESG score based on the funds healthy heart theme. The top 50-80 stocks constitute the funds concentrated portfolio. Stocks are then weighted by market cap, with individual stock weights capped at 5%. The index is rebalanced on a quarterly basis. Prior to Aug. 28, 2024, the fund name was branded under IndexIQ.
