nasdaq closing cross technical

"Nasdaq, Inc. (Nasdaq: NDAQ) today announced the Nasdaq Closing Cross had a record day"

An automated auction held at the end of the trading day that matches all buy and sell orders to produce a single official Nasdaq closing price for a stock. It matters because that closing price is used to calculate indexes, value funds, and benchmark performance; think of it like taking a group photo to pick one representative snapshot of a stock’s price at the day’s end so investors have a fair, standard reference.

russell reconstitution financial

"the Closing Cross has been used to calculate the Russell Reconstitution, which occurs semi-annually"

Russell reconstitution is the periodic review and reshuffling of which companies belong in the Russell family of market-capitalization stock indexes. Think of it as updating the roster of a sports team based on recent performance and size: some companies move up into an index, others drop out. It matters to investors because many funds track these indexes and must buy or sell shares to match the new lineup, which can temporarily affect stock demand, prices and trading volumes.

View in glossary

notional volume financial

"Today’s record notional volume underscores the continued trust the investment community places"

Notional volume is the total dollar value represented by a set of financial contracts — calculated by multiplying the number of contracts by the price of the underlying asset — rather than the count of contracts alone. Think of it like reporting the total cost of items in a shopping cart instead of just how many items are in the cart. Investors use it to gauge the true size, market activity and potential risk or exposure tied to trades or positions.

latency technical

"the Cross has reduced latency by over 85% while effectively keeping pace"

Latency is the time delay between when information or an instruction is created and when it is received, processed, or acted on by a market system or data feed. For investors, that delay can alter the price you receive, cause missed trading opportunities, or increase execution risk — like sending a text to buy an item and the seller acting a few seconds later after the price has changed.

4,594,880,616 shares traded amounting to $334.027 billion

NEW YORK, June 26, 2026 (GLOBE NEWSWIRE) -- Nasdaq, Inc. (Nasdaq: NDAQ) today announced the Nasdaq Closing Cross had a record day as it was used to rebalance Nasdaq-listed securities in the entire family of Russell US Indexes, which includes the Russell 1000, Russell 2000, and Russell 3000. This year marks the 23rd year that the Closing Cross has been used to calculate the Russell Reconstitution, which occurs semi-annually to reflect shifts in the market capitalization, sector dominance, and style orientation of publicly traded US companies.

4,594,880,616 shares, representing a record $334.027 billion, were executed in the Closing Cross in 1.630 seconds across Nasdaq-listed securities, representing the largest liquidity event on the Nasdaq Stock Exchange for the Russell Reconstitution. The new milestone surpasses 2025’s trading volume, which represented 2,506,428,416 shares, totaling $102.455 billion, executed in 0.871 seconds across Nasdaq-listed securities during Russell's annual reconstitution.

"US equity markets have grown materially in scale and complexity, and Russell Reconstitution is one of the clearest tests of that,” said Kevin Kennedy, EVP, North American Markets, Nasdaq. “Today's record shows the infrastructure underpinning the US market close continuing to scale with the market it serves, delivering a single, transparent closing price across record volume in under a second. That is the precision investors expect, and what US market infrastructure is built to deliver.”

“Russell Reconstitution is a cornerstone event for the US equity markets, ensuring the full suite of Russell US Indexes remain precise and representative of the ever-evolving marketplace,” said Fiona Bassett, CEO of FTSE Russell. “Today’s record notional volume underscores the continued trust the investment community places in our transparent and rules-based process. We’re proud to celebrate the successful completion of this year’s first semi-annual rebalancing with our longstanding friends at Nasdaq, marking another milestone in our shared commitment to market integrity and efficiency.”

The Closing Cross brings together buy and sell interests executing all shares for each stock at a single price, one that reflects the accurate supply and demand for these securities. The technology reflects each symbol’s true supply and demand, providing unparalleled insight into the market close.

All Russell US Indexes are subsets of the Russell 3000E™ Index, which represents approximately 98% of the US equity market. Russell US Indexes allow investors to track current and historical market performance by specific market segment (large cap/small cap) or investment style (growth/value/defensive/dynamic). Today, approximately $10.6 trillion in assets are benchmarked to or invested in products based on the Russell US Indexes.

Russell Reconstitution Day is one of the year’s most highly anticipated and heaviest trading days in the US equity market, as asset managers seek to reconfigure their portfolios to reflect the composition of Russell's newly reconstituted US indexes. The index reconstitution process was completed today, and the newly reconstituted index membership will take effect when markets open on June 29, 2026. Please visit our website for more information on the Nasdaq Closing Cross.

Since the Nasdaq Closing Cross began calculating the Russell Reconstitution over two decades ago, the Cross has reduced latency by over 85% while effectively keeping pace with an increasing trade volume growth of over 550% and an increasing notional volume growth of over 1500%. To maintain the liquidity and resiliency of its systems during these evolving market conditions, Nasdaq has made considerable investments in market modernization and capacity enhancement. These efforts are consistent with Nasdaq's broader commitment to providing technology solutions that enhance transparency and support the global financial ecosystem.
