How will the changes to the Realty Majors Portfolio Index (RMP) and Global Realty Majors Portfolio Index (GRM) affect the valuation of Cohen &âŻSteersâ current holdings?
Short answer:
Because the press release only tells us that CohenâŻ&âŻSteers will make âpending changesâ to the Realty Majors Portfolio Index (RMP) and the Global Realty Majors Portfolio Index (GRM) as of the close of business on 15âŻAugustâŻ2025, the exact impact on the valuation of the firmâs current holdings cannot be quantified from the information that is publicly available today.
What we can say with confidence
What the announcement confirms | What this typically means for valuation |
---|---|
Index composition will be altered (e.g., securities added, removed, or reâweighted) | ⢠Inclusion of a security usually pushes its market price up because indexâtrackers, ETFs, and passive funds must buy the security to match the index. ⢠Exclusion generally exerts downward pressure, as those same vehicles sell the security. |
Effective date is 15âŻAugâŻ2025 (after the close of business) | ⢠The market will price in the change on the next trading day (16âŻAugâŻ2025). ⢠Any reâbalancing trades that CohenâŻ&âŻSteers (or its managed funds) must execute will be reflected in the midâday NAV of its own listed products, but the indexâchange itself does not directly alter the firmâs balanceâsheet valuation until the market reacts. |
No details on the nature of the changes (e.g., sector tilt, marketâcap thresholds, ESG screens) | ⢠The magnitude of the valuation effect depends on how many securities are affected and how large the weighting adjustments are. ⢠If the changes are modest (e.g., a few securities swapped or a slight reâweighting), the impact on the overall portfolio value will be limited to the price movement of those specific holdings. ⢠If the changes are sweeping (e.g., a new regional exposure, a major ESG filter, or a shift from âmajorâ to âmidâcapâ realâestate assets), the valuation impact could be material, affecting a sizable portion of the current holdings. |
Typical ways index changes translate into valuation adjustments for a manager like CohenâŻ&âŻSteers
Price impact on individual securities â
If a current holding is slated to be *added** to the RMP/GRM, demand from indexâfunds and passive strategies will rise, often lifting the securityâs price. The opposite occurs for securities that will be removed.*NAV (Net Asset Value) of CohenâŻ&âŻSteersâmanaged products â
CohenâŻ&âŻSteers runs a suite of listed and private realâestate products that track the RMP and GRM. When the index composition changes, the *midâday NAV** of those products is recalculated using the new weightings. A higherâpriced inclusion will boost NAV; a lowerâpriced exclusion will depress it.*Liquidity and trading costs â
Reâbalancing to meet the new index weights can generate shortâterm trading activity. If the index adds lessâliquid REITs or privateâequity holdings, CohenâŻ&âŻSteers may incur higher transaction costs, which can modestly dent the net valuation of the holdings during the transition.Benchmark performance attribution â
Because the RMP and GRM serve as benchmarks for many of CohenâŻ&âŻSteersâ own funds, any change will reset the âbenchmarkâ against which performance is measured. A more favorable index composition (e.g., adding higherâyielding or higherâgrowth assets) can make the *relative performance** of existing holdings look better, even if the absolute market value is unchanged.*Potential secondary effects â
Index changes often trigger *analyst coverage upgrades/downgrades** and can affect creditârating outlooks for the affected securities. Those secondary signals can further influence market pricing and thus the valuation of the holdings.*
What we still do not know (and therefore cannot quantify)
Missing piece | Why it matters for valuation |
---|---|
Exact securities being added or removed | Determines which tickers will see buying or selling pressure. |
Weighting adjustments (e.g., from 5âŻ% to 12âŻ% of the index) | Larger weight changes create bigger price moves and larger NAV impacts. |
Methodology tweaks (e.g., new ESG screening, regional caps, marketâcap thresholds) | Could shift the riskâreturn profile of the index, affecting discount/premium valuations of the underlying assets. |
Whether the changes are âadministrativeâ (e.g., corporate actions) or âstrategicâ (e.g., sector reallocation) | Administrative changes usually have minimal price impact; strategic reallocation can be material. |
Bottomâline takeâaway for investors
- Shortâterm: Expect the market to price in the index changes on 16âŻAugustâŻ2025 (the first trading day after the effective close). Securities slated for inclusion will likely see a modest price uptick; those slated for removal may face a modest decline.
- Portfolioâlevel: The net effect on CohenâŻ&âŻSteersâ current holdings will be proportional to the number of securities impacted and the size of the weighting changes. In the absence of a detailed list, the impact is best described as âpotentially modest to moderateâ rather than a guaranteed large swing.
- Longâterm: Once the new index composition settles, the benchmark will reflect the revised sector/region exposure, and CohenâŻ&âŻSteersâ own funds that track the RMP/GRM will have a new performance baseline. The valuation of the holdings will then be judged against that new benchmark, not the preâchange version.
What you can do next
- Monitor the AugustâŻ15â16âŻ2025 trading days for any press releases or SEC filings that list the specific securities being added/removed.
- Check the updated index methodology (often posted on the CohenâŻ&âŻSteers website or on the index providerâs portal) for details on weighting limits, ESG screens, or regional caps.
- Review the NAV disclosures of CohenâŻ&âŻSteersâ listed products (e.g., the âCohenâŻ&âŻSteers Realty Majors Portfolioâ ETF) for the dayâafterâchange NAV calculation, which will show the immediate valuation impact.
- Consider the tradingâcost impact if you hold a sizable position in the affected securitiesâreâbalancing can temporarily compress spreads.
In summary, while the announcement confirms that the RMP and GRM will be altered on 15âŻAugustâŻ2025, the precise valuation effect on CohenâŻ&âŻSteersâ existing holdings cannot be quantified until the specific composition changes are disclosed. Historically, such index adjustments lead to shortâterm price movements for the securities involved and a reâcalibration of the NAVs of any funds that track the indexes, but the overall magnitude will depend on the details of the changes.
