Shares of several Solana-focused digital asset treasury (DAT) companies rose on Friday as SOL climbed about 9%.

According to Odaily, Sol Strategies (STKE) led the group, rising as much as 22% intraday to a high of $1.20.

Other Solana DAT stocks also posted gains. Forward Industries (FWDI) rose as much as 12% intraday to $4.03, SkyAI (SKYA) gained 11% to $1.07, and DeFi Development Corp. (DFDV) advanced 10% to $2.73. Solana Company (HSDT) rose more than 10%, reaching an intraday high of $1.65.

The moves were also supported by expectations of index inclusion. Several digital asset treasury companies, including Forward Industries, are set to be added to Russell indexes after Friday’s market close.

Two Ethereum treasury companies, Bitmine (BMNR) and SharpLink (SBET), are also slated for inclusion in related Russell indexes, while smaller Solana treasury company Upexi (UPXI) is expected to join the Russell Microcap index.
