at Bloomberg.<\/span><\/i><\/p>\n<p>With the recent news pertaining to <a href=\"https:\/\/www.bloomberg.com\/news\/videos\/2025-01-16\/ftse-russell-ceo-on-move-to-semi-annual-reconstitution-video\">FTSE Russell<\/a>\u2019s US equity indices, investors are suddenly taking note of reconstitution frequency. During an index reconstitution, securities are selected for inclusion or removal based on rules set out in the index methodology. While client feedback certainly played a role in FTSE Russell\u2019s decision to move to a semi-annual schedule (starting in November 2026), it was surely driven by other factors as well, including to some extent, factors. The impact of reconstitution schedules can be seen when evaluating indices through a factor lens. There are indeed benefits to more frequent reconstitution, but there are tradeoffs as well.<\/p>\n<p>Securities that have moved in market capitalization will get reassigned to a size index based on those movements during a reconstitution. In addition, for style investors, reconstitution will take a fresh snapshot of what companies are growing earnings and which ones are becoming cheaper. The Bloomberg U.S. size and style equity indices have always conducted semi-annual reconstitutions, whereby eligible securities are ranked by market capitalization and assigned to a respective index based on that rank. By performing reconstitutions semi-annually, Bloomberg\u2019s indices strike an effective balance of keeping indices well represented as markets change, while limiting unnecessary turnover.<\/p>\n\n<\/div>\n\n\n<\/div>\n\n\n                    <\/div>\n    <\/section>\n<\/div>\n\n<div  class=\"bbg-row-container\">\n    <section class=\"bbg-row  text--black row-padding--top-none row-padding--bottom-none bbg-row--margin-top-compact bbg-row--margin-bottom-compact bbg-row--full-bg-bleed\" data-anchor='row-6a09bdca45596'>\n        \n        \n        <div\n            class=\"bbg-row--content\"\n                    >\n            \n            <div\n    class=\"bbg-column\"\n    style=\"\"\n    >\n    <div class=\"bbg-interstitial\" aria-label=\"interstitial\" tabindex=\"0\">\n\t<style>\n\t\t.bbg-interstitial #card_1.bbg-card_hasCta{\n\t\t\tbackground: url(https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Interstitial_bg.png);\n\t\t\t\tbackground-repeat: no-repeat;\n\t\t\t\tbackground-position: center center;\n\t\t\t\tbackground-size: cover;\n\t\t\tpadding: 104px;\n\t\t\t\n\t\t\t\n\t\t}\n\t\t.bbg-interstitial #card_1.bbg-card_hasCta .bbg-card__content, .bbg-interstitial #card_1.bbg-card_hasCta .bbg-card__content p{\n\t\t\tcolor:white;\n\t\t}\n\t\t@media (max-width: 768px) {\n\t\t\t.bbg-interstitial #card_1.bbg-card_hasCta{\n\t\t\t\tpadding: 80px 32px;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 480px) {\n\t\t\t.bbg-interstitial #card_1.bbg-card_hasCta{\n\t\t\t\tpadding: 80px 18px;\n\t\t\t}\n\t\t}\n\t<\/style>\n\t<div class=\"wpb_content_element bbg-card  bbg-card-dark bbg-card_hasCta has_interstitial\" id=\"card_1\" data-card_type=\"no_image\">\n  \n  \n  <div class=\"bbg-card__innerwrapper\">\n    <div class=\"bbg-card__content\">\n      \n      \n                      <h3 class=\"bbg-card__title\">Discover more with Bloomberg newsletters<\/h3>\n      \n              <div class=\"bbg-card__wysiwyg bb-wysiwyg\"><p>Subscribe now<\/p>\n<\/div>\n          <\/div>\n\n          \n<div\n  id=\"cta_653946594747503421\"\n  class=\"wpb_content_element bbg-cta icon icon-arrow\">\n  <style>\n    \n    \n    \n  <\/style>\n  <div\n    class=\"bbg-cta-link link-holder\"\n    data-links-type=\"cta-links\">\n    <p class=\"bbg-cta-p right\">\n      <a\n        class=\"bbg-cta-link link interstitial_cta\"\n        href=\"https:\/\/www.bloomberg.com\/professional\/insights\/newsletter\/\"\n        target=\"\"\n        rel=\"\"\n        data-section-name=\"\"\n                role=\"button\"\n        aria-label=\"Learn more\"\n        >\n                <\/a>\n    <\/p>\n  <\/div>\n<\/div>\n\n      <\/div>\n\n  <\/div>\n\n<\/div>\n\n\n<\/div>\n\n\n                    <\/div>\n    <\/section>\n<\/div>\n\n<div  class=\"bbg-row-container\">\n    <section class=\"bbg-row  text--black row-padding--top-compact row-padding--bottom-none bbg-row--full-bg-bleed\" data-anchor='row-6a09bdca4ae29'>\n        \n        \n        <div\n            class=\"bbg-row--content\"\n                    >\n            \n            <p><div\n    class=\"bbg-column bbg-column--width-2\"\n    style=\"\"\n    >\n    \n<\/div><div\n    class=\"bbg-column bbg-column--width-8\"\n    style=\"\"\n    >\n    <p><div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<p>Reconstitution frequency can especially impact smaller cap indices. A small cap stock that appreciates in price can quickly move to a mid-cap classification, but perhaps not into a mid-cap index. As a result, assuming all else is equal, a small cap index that reconstitutes less frequently may have a higher allocation to larger companies. From a factor perspective, this means less frequent reconstitution could lead to less exposure to the low size factor. But the factor impact goes beyond small size.<\/p>\n<p>Momentum is a factor that measures the price movement of a stock relative to others in its universe. A stock that exhibits high momentum exposure is typically increasing in market capitalization at a faster rate than peers. As a result, small cap names that are getting larger will often have high momentum exposure. Should these names remain in an index longer due to low reconstitution frequency, they may increase an index\u2019s exposure to the momentum factor. In addition, the momentum factor is often associated with the growth style and has a negative correlation to the value factor. Take the price-to-earnings ratio for example. If a stock\u2019s price is moving up without a similar move in earnings, then it is becoming more expensive from a fundamental\u2019s perspective. Because of this, a risk model like Bloomberg\u2019s MAC3 will show that stock as having lower exposure to the value factor.<\/p>\n<p>A recent case study that illustrates this was the rise of <a href=\"https:\/\/www.bloomberg.com\/professional\/insights\/data\/super-micros-rise-calls-for-index-responsiveness\/\">Super Micro (SMCI)<\/a>. Super Micro saw its market capitalization appreciate rapidly during 2023, yet remained in some small cap indices for a long period of time due to the frequency of reconstitutions. The Russell 2000 index, the most popular benchmark for small cap managers, did not promote the company to the larger Russell 1000 until their June reconstitution of the following year. At that point, the stock had surpassed $40 billion in market cap and was ranked within the top 600 stocks in the US by market capitalization.<\/p>\n\n<\/div>\n<div id=\"\" class=\"wpb_content_element bbg-single-image align-center\">\n    <figure class=\"bbg-single-image__figure\" style=\"max-width:1024px\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"475\" src=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png\" class=\"bbg-single-image__image attachment-large\" alt=\"SCMI Market Cap and Index Changes\" title=\"SCMI Market Cap and Index Changes\" srcset=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 800w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 552w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 100w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 768w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 182w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/Screenshot-2025-02-12-at-9.26.36%E2%80%AFAM.png 977w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/>\n        \n            <\/figure>\n<\/div>\n\n<div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<p>Using the TLTS function in Bloomberg, we can see the factor impact of reconstitution frequency by comparing similar indices around this time. The <a href=\"https:\/\/www.bloomberg.com\/professional\/products\/indices\/quote\/b2000t:ind\">Bloomberg 2000<\/a> takes a similar approach to the Russell small cap equivalent in terms of security selection, however, the B2000 has always reconstituted semi-annually in March and September. The below analysis compares that index to an ETF tracking the Russell 2000 for the six months prior to SMCI\u2019s promotion in the Russell universe. By that point, SMCI had already been moved out of the small cap Bloomberg 2000 into the larger <a href=\"https:\/\/www.bloomberg.com\/professional\/products\/indices\/quote\/b1000t:ind\">Bloomberg 1000<\/a>. During the range shown, the Russell 2000 fund had higher exposure to larger size, momentum, and growth factors. The exposure to those factors was at its highest in March 2024, which coincided with SMCI\u2019s price peak.<\/p>\n\n<\/div>\n<div id=\"\" class=\"wpb_content_element bbg-single-image align-center\">\n    <figure class=\"bbg-single-image__figure\" style=\"max-width:1024px\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"464\" src=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg\" class=\"bbg-single-image__image attachment-large\" alt=\"TLTS Factor Analysis 12\/31\/2023-06\/28\/2024: Russell 2000 ETF vs Bloomberg 2000\" title=\"recon2\" srcset=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg 800w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg 552w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg 768w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg 186w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon2.jpg 949w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/>\n        \n            <\/figure>\n<\/div>\n\n<div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<p>While the factor exposures above may be too small to qualify as a true \u201ctilt\u201d and would be deemed as noise by some quantitative analysts, the active exposure is persistent when looking over a multi-year period. \u00a0When we run a similar analysis over the 5 year period through year-end, this and other active exposures, albeit small, can still be observed.<\/p>\n\n<\/div>\n<div id=\"\" class=\"wpb_content_element bbg-single-image align-center\">\n    <figure class=\"bbg-single-image__figure\" style=\"max-width:1024px\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"485\" src=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg\" class=\"bbg-single-image__image attachment-large\" alt=\"TLTS Factor Analysis 12\/31\/2019-06\/28\/2024: Russell 2000 ETF vs Bloomberg 2000\" title=\"recon3\" srcset=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 800w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 552w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 100w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 768w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 178w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon3.jpg 923w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/>\n        \n            <\/figure>\n<\/div>\n\n<div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<p>Naturally some might ask \u201cWhy not reconstitute even more frequently, perhaps quarterly or monthly?\u201d.

While the days of equities trading in \u201ceighths\u201d is long gone, bid-offer spreads do still exist and can be wide, especially for smaller cap stocks. \u201cPaying the spread\u201d can eat into returns, and the weighted average bid offer spread of the constituents in the Bloomberg 2000 (small cap) is four times that of the Bloomberg 1000 (Large\/Mid). This is just one aspect of transaction costs, as commissions and taxes are also considerations for investors.<\/p>\n\n<\/div>\n<div id=\"\" class=\"wpb_content_element bbg-single-image align-center\">\n    <figure class=\"bbg-single-image__figure\" style=\"max-width:1024px\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"725\" height=\"457\" src=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon4.jpg\" class=\"bbg-single-image__image attachment-large\" alt=\"Bid offer spread\" title=\"recon4\" srcset=\"https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon4.jpg 725w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon4.jpg 552w, https:\/\/assets.bbhub.io\/image\/v1\/resize?width=auto&amp;type=webp&amp;url=https:\/\/assets.bbhub.io\/professional\/sites\/41\/recon4.jpg 171w\" sizes=\"auto, (max-width: 725px) 100vw, 725px\" \/>\n        \n            <\/figure>\n<\/div>\n\n<div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<p>Indices serve a vital role for investors of all types, and as such, should be diligently constructed to meet varying needs. Their construction should demonstrate both data and investment expertise, conscious of identifiable pitfalls and overly simplistic shortcomings. Active managers focused on a particular market capitalization should have their relative performance compared to a benchmark that is responsive, as that relative performance may be skewed by a stock that would otherwise be removed but for reconstitution schedule \u2013 or one that should be included and hasn\u2019t yet. Additionally, managers may have to trade more frequently to account for stocks that are being added or removed from their investment universe.<\/p>\n<p>Bloomberg equity indices aim to strike a precise balance of keeping indices well represented as markets change with a responsive rules-based approach, while still maintaining the low turnover (and low transaction costs), managers expect from their passive benchmarks. It is for these and other reasons that Bloomberg created our indices from the start to reconstitute on a semi-annual basis. Equity markets have evolved, allowing investors greater access at increased levels of speed, resulting in ever-faster moving markets. As such, indices need to be constructed in a way to ensure they maintain representativeness.<\/p>\n<p><em><a href=\"https:\/\/www.bloomberg.com\/professional\/products\/indices\/equity\/\">Learn more<\/a> about Bloomberg\u2019s equity index offerings.<\/em><\/p>\n\n<\/div>\n<div\n\tclass=\"bb-wysiwyg\"\n\t\t>\n\t<h6><em>The data and other information included in this publication is for illustrative purposes only, available \u201cas is\u201d, non-binding and constitutes the provision of factual information, rather than financial product advice.
