Dow, Nasdaq Rise as Bond Yields Fall; Corning, Biotech Lead

US stocks climbed on Wednesday, with the Dow Jones Industrial Average and the Nasdaq Composite both posting gains as a decline in bond yields lifted growth-oriented sectors. Corning shares surged after the company reported strong demand for its optical fiber products, while biotech stocks broke out on positive trial data from several mid-cap firms. The move lower in Treasury yields provided a tailwind for equities, particularly for longer-duration names in technology and healthcare.

The drop in bond yields reflects a shift in rate expectations, with traders pricing in a higher probability of Federal Reserve rate cuts later this year. The 10-year Treasury yield fell below 4.20%, its lowest level in three weeks, as softer economic data and dovish Fed commentary weighed on the outlook for monetary policy. Lower yields reduce the discount rate applied to future cash flows, making growth stocks more attractive. On NowPrice, live rates and charts show the yield curve steepening slightly, with the 2-year yield declining more than the 10-year, suggesting the market is front-running a potential easing cycle.

Looking ahead, traders will focus on the upcoming personal consumption expenditures (PCE) price index report, the Fed's preferred inflation gauge, due later this week. A softer reading could reinforce the case for rate cuts and further support equities. Additionally, earnings from major tech companies next week will test whether the current risk-on momentum can be sustained. Key levels to watch include the 4.15% area on the 10-year yield; a break below could trigger further short-covering in bonds and extend the equity rally.
