US Stocks Rise Slightly as Bond Yields Fall; Moderna Jumps

US equity markets posted modest gains as declining Treasury yields encouraged investors to move toward riskier assets, according to market reports.

The shift reflects growing risk appetite among investors, who tend to favour stocks over bonds when yields fall and borrowing costs ease.

The Dow Jones Industrial Average opened higher and advanced by as much as 300 points during the session, buoyed by improved sentiment.

The rally was supported by news that the US Treasury Department had been purchasing government bonds, a move that was welcomed by markets and helped drive yields lower.

Shares of Moderna, the pharmaceutical firm, surged sharply, although the underlying reason was not detailed in available reports.

The gains occurred even as US stocks trade near their record highs, prompting renewed debate over whether current valuations still represent good buying opportunities.

Market participants remain split. Bullish investors argue that favourable conditions, including easing yields, justify further gains despite elevated valuations.

Bearish investors, by contrast, caution that stocks trading at record levels may be vulnerable to a correction, especially if economic conditions shift.

The debate between the two camps underscores broader uncertainty about the market's direction, even as short-term sentiment appears to have improved following the Treasury-related news.

Analysts note that such divergent views are typical when markets approach historic peaks, with both bulls and bears citing different economic signals to support their positions.
