National Bank of Canada strategists are flagging a critical tension in US equity markets as the S&P 500 reaches new record highs in August. The index has been propelled by an exceptional second quarter earnings season, with companies delivering approximately 50 percent year-over-year earnings per share growth. However, NBC warns that valuation levels have now stretched to concerning territory despite the robust fundamental performance.

The warning comes as traders have pushed the benchmark index higher on the back of strong corporate results, creating a potential disconnect between price and underlying value. The combination of record highs and stretched valuations raises questions about sustainability of the rally, particularly if earnings momentum slows or economic conditions shift. Market participants across equities, derivatives, and ETF trading desks should monitor valuation metrics closely as positioning remains elevated.

Strong earnings have justified recent gains, but stretched valuations mean any disappointment in upcoming quarterly results could trigger sharp corrections, making risk management essential for current long positions.
