Lori Calvasina, the head of US equity strategy at RBC Capital Markets LLC, has issued a cautionary note regarding the outlook for US equities, suggesting that a sustained rise in benchmark Treasury yields to the 5% mark could significantly challenge current bullish sentiment. Calvasina points out that historically, such high yield levels tend to exert downward pressure on stock price-to-earnings (P/E) ratios. When risk-free rates climb this high, the present value of future corporate earnings decreases, making stocks relatively less attractive compared to fixed-income alternatives. This dynamic forces investors to re-evaluate equity valuations, potentially leading to a broad market correction or at least a significant slowdown in growth stock performance. The 5% threshold is viewed as a critical psychological and technical barrier that, if breached and held, could force a major reassessment of equity risk premiums across the board, dampening enthusiasm even among the most optimistic market participants.

Key Points:

- Benchmark US Treasury yields hitting 5% could challenge current bullish outlooks for US stocks.

- High yields typically depress stock price-to-earnings (P/E) ratios by increasing the discount rate on future earnings.

- Lori Calvasina of RBC Capital Markets identifies 5% as a critical level for equity valuation reassessment.
