Fortunately, we can test the hypothesis that the ETF market is roughly a few thousand different ways to capture the same basic risk\/returns. To do so, we leverage our Portfolio Architect tool to quantify the active share of all US equity ETFs against the S&amp;P 500 index (the king of indexes).<\/p>\n\n\n\n<p>Active share is the percentage of a portfolio\u2019s stock holdings that differ from its benchmark index (in this case, the S&amp;P 500).&nbsp;The measure is based on the weightings of securities in a portfolio compared with those of its benchmark and can be used as a measure of the degree of a portfolio\u2019s active management. An active share of 0, would imply there is a 0% difference between a given ETF and the SP500. An active share of 100 would imply there is a 100% difference in holdings\/weights between a given ETF and the SP500. And then you have everything in between.<\/p>\n\n\n\n<p>As a general rule of thumb, we consider any strategy with an active share of less than 30% to be a \u2018closet index\u2019, which refers to a strategy that is effectively the same as the underlying index it seeks to track.<\/p>\n\n\n\n<p>Here is the distribution of active shares across the 1814 US Exchange Traded Equity ETFs we track in our database against SPY (what we use as the SP500 holdings benchmark).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1100\" height=\"679\" data-src=\"\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect-1100x679.png\" alt=\"\" class=\"wp-image-142928 lazyload\" data-srcset=\"https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect-1100x679.png 1100w, https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect-700x432.png 700w, https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect-300x185.png 300w, https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect-768x474.png 768w, https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/06\/active-share-1200x741-alpha-architect.png 1200w\" data-sizes=\"(max-width: 1100px) 100vw, 1100px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1100px; aspect-ratio: 1100\/679;\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">Source: Portfolio Architect<\/p>\n\n\n\n<p>Key Points:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A bit over 4% of all funds are S&amp;P 500 closet-trackers.
