The S&P 500 reached a new record high in August, driven by robust earnings performance in the second quarter. According to FX Street, the index's gains were supported by approximately 50% year-on-year growth in earnings per share (EPS) during Q2.

This significant earnings growth reflects strong corporate profitability, which has contributed to positive investor sentiment in US equities. The National Bank of Canada (NBC) has also noted the strength of these earnings results, reinforcing the market's upward momentum.

For Japanese investors, the S&P 500's record performance underscores the resilience of US markets amid global economic uncertainties, highlighting opportunities for portfolio diversification into US equities and related FX trades.
