On September 17, ProShares UltraPro QQQ rose 5.02% in regular trading, trading at $71.30 per share, with turnover of $1.46 billion. The rally closely tracked a broad Nasdaq 100 advance amplified by the fund's 3x daily leverage design.

On the news front, the Federal Reserve announced a 25-basis-point rate hike to 3.75%–4.00%, its first increase since July 2023. Markets had largely priced in the move, and the decision triggered a classic sell-the-rumor, buy-the-news reaction. The 10-year U.S. Treasury yield eased to approximately 4.959%, retreating from the psychologically critical 5% threshold, reducing valuation pressure on growth equities. The VIX fear index dropped 8.86% to 16.15, signaling a sharp improvement in risk appetite.

U.S. major indices opened strongly — the Dow gained 0.9%, the S&P 500 rose 1.2%, and the Nasdaq climbed 1.5%. Semiconductor stocks rallied broadly, with ARM surging over 8%, Marvell Technology up over 5%, and Intel gaining over 4%.

ProShares UltraPro QQQ seeks daily investment results that correspond to three times the daily performance of the Nasdaq-100 Index, which includes 100 of the largest domestic and international non-financial companies listed on the Nasdaq Stock Market. The fund is non-diversified.
