ARM•ARM shares plunged 6.43% after July CPI rose 0.2% month-over-month and 3.5% year-over-year, sending the 10-year Treasury yield up 10 basis points to 4.1%. The jump in bond yields could boost ARM’s discount rate by 30 basis points, trimming as much as 8% from its equity valuation.
1. July Inflation Exceeds Forecasts
July’s consumer price index climbed 0.2% month-over-month and 3.5% year-over-year, compared with consensus estimates of 0.1% and 3.3%, respectively. Sticky service and shelter costs drove the upside surprise, stoking fears of a more hawkish Federal Reserve stance.
2. 10-Year Treasury Yield Spikes to 4.1%
In response to hotter inflation data, the benchmark 10-year Treasury yield jumped 10 basis points to 4.10%, marking its highest close since early June. The move increased borrowing costs and raised discount rates across growth sectors.
3. ARM Stock Plunges 6.43% on Rate Shock
Shares of ARM fell 6.43% as investors sold growth names vulnerable to rising rates. The drop reflects recalibrated cash-flow models that now incorporate higher financing costs.
4. Valuation Impact Could Reach 8% Downside
