UPRO is trading at $150.17, down 3.36%, as September inflation exceeded expectations and lifted Treasury yields and rate-hike expectations. - September CPI rose 3.7% year over year versus 3.6% expected; core CPI was 2.6% versus 2.5% expected. - Yield pressures weighed on the S&P 500, especially technology and semiconductor shares. UPRO’s leveraged S&P 500 exposure can magnify daily declines, while chip-sector weakness added to the drag as investors reassessed rate-sensitive growth stocks.
