[BRIEFING.COM] The S&P 500 (+0.26%) is in second place on Monday afternoon, up about 17 points.

Briefly, S&P 500 constituents Western Digital (WDC 114.90, +8.02, +7.50%), The Trade Desk (TTD 50.43, +3.29, +6.98%), and Kellanova (K 81.99, +4.05, +5.20%) pepper the top of the standings. WDC rises after multiple analysts raised price targets, citing an emerging multi-year HDD upcycle fueled by AI-driven data center demand, supply shortages, and stronger pricing power, while Kellanova advances amid reports the company may get clearance from the European Union for its Mars deal.

Meanwhile, Devon Energy (DVN 35.59, -1.40, -3.78%) is one of today's worst performers, slipping as today's fall in crude oil prices dents the stock.
