You can follow the latest updates on the market here in our daily live blog.Update: 9:53 a.m. ETRussell 2000, Nasdaq Turn Negative In Early TradingAfter starting the trading session up about 0.40%, the Russell 2000 (-0.08%) and Nasdaq Composite (-0.02%) are now in the red. Here's the latter as of this morning, per TradingView: Much of this decline seems to be led by modest declines across the tech industry; in software, electronics, and communication services. Both large names like Broadcom (-2.39%) and small names like Soundhound (-3.2%) are among the decliners.Still, the U.S. markets are looking in pretty good shape, with data from FinViz advising that over half of equities are advancing this morning -- even despite the tepid start to the day.Maybe the brightest spot is in financials. The S&P 500's Financial Sector just hit an all-time high, continuing a recent rally. That's happening even as the S&P 500 (+0.13%) and Dow (+0.09%) have faced declines from their opening prints.Update: 9:34 a.m. ETOpening BellHappy opening bell (to those who celebrate.) The U.S. markets are now open for the last full trading week of 2025.This morning, the Russell 2000 (+0.43%) is continuing a days-long streak spurred by rate cut optimism and a healthy catch-up trade in small caps. As of today, it's up more than 15% year-to-date, putting it ahead of the Dow -- and on similar footing with one-time large cap leaders.Speaking of large-caps, the Nasdaq (+0.37%) and S&P 500 (+0.33%) aren't far behind the Russell, trailed by lagging Dow (+0.26%). Notably, all four equity benchmarks are lagging out of the gate -- but perhaps none worse than the Nasdaq. We'll be keeping an eye on it this morning, particularly since tech has been struggling in recent sessions.Starting the week, the 10YTreasury (-3.9 bips to 4.157%), 20Y Treasury (-3.7 bips to 4.784%), and 30Y Treasury (-3.5 bips to 4.823%) are all seeing declines in yields this morning. The nearer it is, the bigger the fall.In continuous contract land, Silver is 2.9% higher this morning at $63.805, joined by a rising Gold (+0.68% to $4,357.80). In energy futures, Natural Gas (-1.26% to $4.061) and Brent Crude (-0.41% to $60.87) are both declining, continuing a recent trend.Update: 8:31 a.m. ETPremarket Movers: Doximity, Lumentum, Zillow Group, ServiceNowAs we head towards the market open, here are the stocks making the biggest moves, per data from MarketWatch: Update: 8:31 a.m. ETA.M.
