  • The gaming stock is joining the widely followed small-cap gauge
  • The stock more than doubled over the past year
  • It’s actually a mid-cap stock as its market value is $6.08 billion

Shares of Rush Street Interactive (NYSE: RSI) rallied in after-hours trading Friday, gaining more than 5% on news the gaming stock will be included in a widely followed index of small-cap equities.

After the close of US markets Friday, S&P Dow Jones Indices announced additions and deletions to S&P 500, S&P MidCap 400, and S&P SmallCap 600 indexes with Rush Street Interactive making the cut to join the small-cap benchmark.

The changes ensure that each index is more representative of its market capitalization range. The companies being removed from S&P MidCap 400 and S&P SmallCap 600 are no longer representative of the mid-cap and small-cap market space, respectively,” said the index provider in a statement.

Chicago-based Rush Street, a leading iGaming operator, is one of 15 stocks that will join the S&P SmallCap 600 prior to the start of trading on Monday, June 22 and is the only gaming equity in the group.

Index Inclusion May Propel Rush Street Interactive Stock

With a market capitalization of $6.08 billion, Rush Street Interactive is actually a mid-cap stock, implying the next logical move is for it to join the S&P MidCap 400, but nonetheless, its inclusion in the small-cap index is potentially encouraging to investors.

The reasoning is simple. Passive funds, including exchanging traded funds (ETFs), tracking the S&P SmallCap 600 as well as active managers benchmarking to that gauge will be forced to buy Rush Street Interactive to remain in-line with the index.

While it’s not the S&P 500, the S&P SmallCap has a significant amount of capital tracking it. For example, the iShares Core S&P Small-Cap ETF (NYSE: IJR) has nearly $103 billion assets under management while the Vanguard S&P SmallCap 600 ETF (NYSE: VIOO) has $3.88 billion in assets. Both funds track the index Rush Street Interactive is joining.

The gaming stock is already a member of the Russell 2000 Index, which is the primary competitor to the S&P SmallCap 600.

Rush Street Interactive Stock Audience Could Increase

With its inclusion in the S&P SmallCap 600, Rush Street Interactive stock could garner more attention from institutional investors. Currently, the stock is in just 69 ETFs, according to ETF Research Center data.

That number will increase with inclusion in the S&P gauge, which also positions the stock to be added to the index’s growth or value counterparts, opening the door to expanded inclusion in a variety of actively managed and passive funds.

Rush Street Interactive is the only gaming stock being added to the S&P 500, S&P MidCap 400, and S&P SmallCap 600 indexes. No wagering names are being deleted from any of those benchmarks.
