Morgan Stanley: Data Center ABS Spreads May Continue to Widen
Morgan Stanley strategists including James Egan and Carolyn Campbell noted in an Oct. 22 report that spreads on asset-backed securities (ABS) supporting data center construction are expected to widen further as companies accelerate AI project financing across various debt markets. The bank views the spread of around 200 basis points on AAA-rated data center ABS as attractive, but investors generally expect room for further widening. Lower-rated securities face a similar trend, though the pace of widening may slow.
The strategists noted that investors are increasingly focused on sponsor risk and questioning whether existing financing structures can adequately address changes brought by AI development over the next decade. Therefore, investors generally demand structures featuring gradual principal amortization or lower leverage. Meanwhile, some ABS backed by GPU loans have begun entering the market. Investors expect such securities to offer shorter maturities, amortize principal prior to maturity, and deliver higher spreads. Morgan Stanley believes that if structural designs meet investor requirements, relevant transactions are likely to gain market acceptance, though pricing will still depend on underlying contract quality and counterparty risk.
Morgan Stanley: Semiconductor Correction May End by Mid-November, with 10% to 15% Downside Risk Remaining
A team of strategists at Morgan Stanley led by Mike Wilson believes the semiconductor sector's correction has entered its final stage, with pressure expected to ease by mid-November, though further declines remain possible before then. The team also maintained its prediction of the S&P 500 Index reaching 8,000 points by year-end. The strategists noted that market doubts over the timing and scale of AI revenue realization have made semiconductors and other sectors benefiting from capital expenditures a focal point of financing concerns. As more financing activities proceed, capital diversion pressure from new issuances may continue to weigh on market sentiment until financing is completed. Based on technical analysis and comparisons with previous silver market trends, the team warned that the semiconductor sector could still fall another 10% to 15%, with the Philadelphia Semiconductor Index potentially finding support around 9,500 points.
