On May 28, Opendoor Technologies rose 8.11% in regular trading, trading at $5.145/share, with trading volume of $118 million. The rally was driven by the company's announcement that it will be included in the Russell 3000 Index as part of the annual reconstitution, with the change set to take effect after the market closes on June 26.

Inclusion in the Russell 3000 Index typically means membership in either the large-cap Russell 1000 Index or the small-cap Russell 2000 Index, as well as in relevant growth and value-style indexes. Index inclusion generally triggers passive fund buying as ETFs and index-tracking funds rebalance their portfolios to reflect the updated composition. This marks a continuation of positive momentum for the stock, which also gained over 8% in the prior session on the same news.

Within the Real Estate Services sector, most peers traded lower, with CBRE Group down 3.02%, Jones Lang LaSalle down 2.71%, KE Holdings down 1.32%, Zillow down 1.17%, while CoStar edged up 0.22%, highlighting Opendoor's relative outperformance on its company-specific catalyst.
