On June 9, GraniteShares 2x Long MRVL ETF rose 8.35% in pre-market trading, trading at $190.95/share, with trading volume of $9.92 million. The leveraged ETF's gain reflects continued strength in its underlying stock, Marvell Technology (MRVL).

On the news front, S&P Dow Jones Indices announced that Marvell Technology will be added to the S&P 500 index, effective before market open on June 22. The inclusion is expected to attract substantial passive fund inflows, as index-tracking ETFs and restricted-mandate active funds will need to purchase shares. On June 8, MRVL surged as much as 15.6% intraday to $304.96, leading the Philadelphia Semiconductor Index higher by 6.6%.

The S&P 500 inclusion follows NVIDIA CEO Jensen Huang's public endorsement on June 3, calling Marvell the next trillion-dollar company due to its critical role in data center connectivity chips. Marvell's market cap now exceeds $230 billion, far surpassing the index's $22 billion minimum threshold. Over 97% of the company's revenue is tied to data infrastructure markets.
