You can follow the latest updates on the market here in our daily live blog.</p><h3>Update: 12:47 p.m. ET</h3><h2>Midday Movers</h2><p>It's that time of day again. Everyday around the midpoint of trading, we take a look at the best and worst-performing 20 stocks on the U.S. markets with at least a $2 billion market cap, our Midday Movers list. And with markets tilted to the downside right now, this list is definitely telling a clear story:</p><h3>Winners</h3><p>We'll start with the more diverse list of equities today -- the winners.</p><p>At the top of the market today is <strong>Immunome </strong>(+18.2%), a biotech company that just announced positive results from a phase 3 trial of a drug targeting Desmond tumors.</p><p>The winners today are definitely more varied than the losers (more on that in a second), but there are some common themes.</p><p>For one, apparel names <strong>Abercrombie &amp; Fitch </strong>(+6.2%) and <strong>American Eagle </strong>(+6%) are on the move today, joined by some other retail names like <strong>GameStop </strong>(+5%) and <strong>Wayfair </strong>(+4.9%).</p><p>Second are auto manufacturers like <strong>Vinfast </strong>(+8%), <strong>Tesla </strong>(+3.9%), and <strong>Rivian </strong>(+3.8%). While the Vietnamese EV firm seems to be surging on plans to increase its investment in Indonesia, the latter two seem to be jumping on self-driving and AI chatter.</p><p>Here is today's top 20:</p><figure><div><div><p><span><img src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/mSwMUWvNBkwpjfl44NfSeQ--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTMyMg--/https://media.zenfs.com/en/thestreet_881/ed192a71fe050fdc0d869b09b52d7e40?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="959" height="322" original-src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/mSwMUWvNBkwpjfl44NfSeQ--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTMyMg--/https://media.zenfs.com/en/thestreet_881/ed192a71fe050fdc0d869b09b52d7e40"/></span></p></div></div></figure><h3>Losers</h3><p>It's pretty clear cut where today's losers are at. (If you've been following this morning, you've seen the heat maps.)</p><p>At the bottom of the market is crypto miner <strong>Cleanspark </strong>(-15.2%). It's hardly alone. In fact, over half of the names on this list today are crypto-related -- take a look at those 'capital markets' names, plus <strong>Applied Digital</strong>, which bills itself an IT services company but owns a pretty hefty digital assets treasury.</p><p>Today's decline comes as the crypto market cap fell below $3 trillion, down 3% today. <strong>Bitcoin </strong>is now below $86K, while <strong>Ethereum </strong>is back below $3K.</p><p>Here's the bottom 20:</p><figure><div><div><p><span><img src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/SNZYNqBsMwEpZSj3dsqUcg--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTMyMw--/https://media.zenfs.com/en/thestreet_881/5e6eb674af87b3a96510506b53024927?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="959" height="323" original-src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/SNZYNqBsMwEpZSj3dsqUcg--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTMyMw--/https://media.zenfs.com/en/thestreet_881/5e6eb674af87b3a96510506b53024927"/></span></p></div></div></figure><h3>Update: 11:58 a.m. ET</h3><h2>In Focus: Russell 2000</h2><p>As we approach midday, things are definitely shaping up differently than how we started the day. Nearly two-thirds of U.S. issues (63%, 3,498 issues) are in decline now.</p><p>Many of those declines are coming from the <strong>Russell 2000</strong> (-0.61%), which started the day on a strong note, but is now suffering a similar fate to its tech heavy large cap compatriot, the <strong>Nasdaq</strong>.</p><p>Today, technology names are sagging -- specifically in software, hardware, and communication services. You can immediately identify that problem on the Russell 2000's heat map:</p><figure><div><div><p><span><img src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/lRXroSLfoEOmk4Xm8q2_9g--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTU1MQ--/https://media.zenfs.com/en/thestreet_881/5cdd2bc5a7869dc92558707e57cd5c1a?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="960" height="551" original-src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/lRXroSLfoEOmk4Xm8q2_9g--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTU1MQ--/https://media.zenfs.com/en/thestreet_881/5cdd2bc5a7869dc92558707e57cd5c1a"/></span></p></div></div></figure><p>Other pockets of red are also worth singling out; specifically, energy, which is in even worse shape than the tech sector amid sagging prices of energy commodities.</p><p>Picking up some of the slack are financials, consumer defense, and industrials names -- but they are largely outnumbered by other sectors and industries.</p><h3>Update: 10:11 a.m. ET</h3><h2>NAHB Housing Index Comes In At 39</h2><p>The NAHB Housing Market Index data for December just released a few minutes ago, coming in at 39 -- the highest reading in eight months.</p><p>Econ hawks were looking for a repeat of last month's data, which came in at 38. That makes this showing a modest beat. However, as the index remains below 50, a sign that current and future conditions remain fairly pessimistic.</p><p>Nonetheless, that's four straight months of improving conditions in the housing market, which have been improved by current sales conditions (+1 pt) and future sales (+1 pt).</p><p>That could be in part because the use of incentives hit their highest percent since Covid in December, with 67% of homes offering some sort of sale incentive.</p><h3>Update: 9:53 a.m. ET</h3><h2>Russell 2000, Nasdaq Turn Negative In Early Trading</h2><p>After starting the trading session up about 0.40%, the <strong>Russell 2000 </strong>(-0.08%) and <strong>Nasdaq Composite </strong>(-0.02%) are now in the red.</p><p>Here's the latter as of this morning, per TradingView:</p><figure><div><div><p><span><img src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/LHYBbjGsXm2TTWXx4x.1pg--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTQ3NA--/https://media.zenfs.com/en/thestreet_881/9a39c20f8e6def9b8991f9f4405c065d?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="960" height="474" original-src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/LHYBbjGsXm2TTWXx4x.1pg--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTQ3NA--/https://media.zenfs.com/en/thestreet_881/9a39c20f8e6def9b8991f9f4405c065d"/></span></p></div></div></figure><p>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 <strong>Broadcom </strong>(-2.39%) and small names like <strong>Soundhound </strong>(-3.2%) are among the decliners.</p><p>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.</p><p>Maybe the brightest spot is in financials. The S&amp;P 500's Financial Sector just hit an all-time high, continuing a recent rally. That's happening even as the <strong>S&amp;P 500 </strong>(+0.13%) and <strong>Dow </strong>(+0.09%) have faced declines from their opening prints.</p><h3>Update: 9:34 a.m. ET</h3><h2>Opening Bell</h2><p>Happy opening bell (to those who celebrate.) The U.S. markets are now open for the last full trading week of 2025.</p><p>This morning, the <strong>Russell 2000 </strong>(+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.</p><p>Speaking of large-caps, the <strong>Nasdaq </strong>(+0.37%) and <strong>S&amp;P 500 </strong>(+0.33%) aren't far behind the Russell, trailed by lagging <strong>Dow </strong>(+0.26%).</p><p>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.</p><p>Starting the week, the <strong>10Y</strong><strong>Treasury</strong> (-3.9 bips to 4.157%), <strong>20Y Treasury </strong>(-3.7 bips to 4.784%), and <strong>30Y Treasury </strong>(-3.5 bips to 4.823%) are all seeing declines in yields this morning. The nearer it is, the bigger the fall.</p><p>In continuous contract land, <strong>Silver </strong>is 2.9% higher this morning at $63.805, joined by a rising <strong>Gold </strong>(+0.68% to $4,357.80). In energy futures, <strong>Natural Gas </strong>(-1.26% to $4.061) and <strong>Brent Crude </strong>(-0.41% to $60.87) are both declining, continuing a recent trend.</p><h3>Update: 8:31 a.m. ET</h3><h2>Premarket Movers: Doximity, Lumentum, Zillow Group, ServiceNow</h2><p>As we head towards the market open, here are the stocks making the biggest moves, per data from MarketWatch:</p><h3>Winners</h3><p><strong>Doximity </strong>(+5.8%), <strong>Lumentum Holdings </strong>(+4.8%), and <strong>MDU Resources Group </strong>(+3.6%) are atop the list of winning equities this morning. You could be forgiven if you have no familiarity with these firms whatsoever. In notable names, <strong>Las Vegas Sands </strong>(+3%), <strong>Micron Technology </strong>(+3%), and <strong>Amer Sports </strong>(+3%) are also making the cut this morning.</p><figure><div><div><p><span><img src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/xwtdQTZPUidru258sCIY_Q--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTY1MA--/https://media.zenfs.com/en/thestreet_881/808dbcdb660cd2dfe539f2ca48a91c13?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="960" height="650" original-src="https://imageproxy.pbkrs.com/https://s.yimg.com/ny/api/res/1.2/xwtdQTZPUidru258sCIY_Q--/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTY1MA--/https://media.zenfs.com/en/thestreet_881/808dbcdb660cd2dfe539f2ca48a91c13"/></span></p></div></div></figure><p>Losers</p><p>At the bottom of the market, <strong>Zillow Group </strong>(-6.2%) is declining on reports that Google is testing a real estate ad format of their own, which could threaten the real estate firm's dominance.
