MSCI August Index Review Announcement Scheduled for August 12, 2026
MSCI Inc. (NYSE:MSCI) said it will announce the results of its August 2026 Index Review for multiple MSCI equity, value and growth, small cap, micro cap, frontier, REIT, and China A and All Shares indexes on Aug. 12, 2026. Changes will take effect after the close of Aug. 31, 2026, with additions and deletions posted on MSCI’s site.
How this was made
The 30-second read
Why it matters
The main tradable element is the timing of the constituent list release and the effective date, which can create mechanical demand/supply shifts for benchmarked securities.
Market read
This is a calendar-style disclosure for MSCI’s Aug 2026 index review, useful for planning around expected rebalancing flows once the constituent changes are published.
What to watch
Traders may need to focus on the specific index families and the effective date mechanics (Aug 31 close) rather than the announcement time alone.
Background
MSCI periodically runs index reviews that result in additions and deletions across multiple MSCI index families, with changes taking effect at a specified cutoff.
Ticker impact
MSCI schedules its August 2026 Index Review results for Aug 12, with index additions and deletions effective after Aug 31 close.
Likely modest, event-driven volatility in affected index constituents around the Aug 12 announcement and Aug 31 effective date, with limited direct impact on MSCI’s own fundamentals.
No constituent list or methodology change is provided, only the timing and that changes become effective as of the Aug 31 close.
Market effects
Index-review-driven rebalancing can affect broad equity, small-cap, value/growth, REIT, and frontier-market baskets tied to MSCI methodologies.
Potential read-through to US equity and REIT constituents, plus MSCI China A and China All Shares constituents, depending on additions/deletions.
MSCI index changes can influence passive and benchmark-tracking flows across multiple regions and market-cap segments.
Counterpoint
Because the article provides only the schedule and not the actual additions/deletions, it may not justify trading until the constituent list is released.
