The blue wave pushed the S&P 500 to its best day in three months, and it still left a trail of red tickers behind it. On Wednesday, Nov. 4, the day after Democrats took both the House and the Senate, investors repriced three big policy bets in a single session: tariffs and AI hardware, energy and permitting, and drug pricing. The scoreboard is not what most people expected.

For context, Yahoo Finance closes show $SPY up 1.65% on the day. $XLF (financials) gained 3.51% and closed at a new 52-week high. Now for the policy bets.
Bet #1: Tariffs and China, so sell the chips? Not quite
The easy story is that a Democratic Congress means a fight over tariffs, and that this hits semis and industrials. The real picture is messier.
According to J.P. Morgan Asset Management, the effective U.S. tariff rate has already fallen to about 10.6%, down from roughly 30% after “Liberation Day.” J.P. Morgan says the Supreme Court struck down the emergency-power tariffs in February, and the administration has since leaned on Section 301. It also says a Democratic Congress “will be limited in its ability to lower tariffs on its own,” and that overriding a veto would take about a dozen Republican senators. In other words, the President still holds the tariff pen.
So why did chips drop? $SMH fell 2.75%, and Investor’s Business Daily reported that the Philadelphia Semiconductor Index fell 3.1%, after sliding as much as 5.1%, to its lowest level since late April. The pressure came from data centers, not trade. CNBC noted that Texas’s Democratic governor-elect has promised a data center moratorium. It also reported that Micron fell 7%, CoreWeave slid 9.9%, and Vistra lost 13.8%. Quartz, citing a Wells Fargo estimate, said Texas holds 27% of planned U.S. data center gigawatts.
Industrials were split. $XLI slipped 1.09%, and defense names took the hardest hit. CNBC reported Lockheed Martin -6.9%, Northrop Grumman -4.5% and RTX -2.4%. Airlines rallied 6% to 8% on the “affordability trade.”
Opinion: The tariff trade is a head fake. Congress can hold hearings, but it can’t easily take the tariff pen away. The real political risk to the chip trade is the local fight over data centers: power bills, water and zoning. Watch the state houses, not just Capitol Hill.
Bet #2: Energy permitting, oil and uranium
This is where the tape got violent. $XLE fell 4.74%, and the exploration-and-production ETF $XOP fell 6.39%. But permitting wasn’t the main driver. Reuters (via Yahoo Finance) reported that Brent fell nearly 9% to settle at $94.62 a barrel, after President Trump acknowledged that the Iran war had played a role in his party’s defeat. In a separate Reuters wrap, Brent was down nearly 20% for the week so far.
On permitting itself, J.P. Morgan says bipartisan permitting reform “could help by accelerating new power generation and transmission.” It also warns that local moratoriums and tougher permitting rules could delay data center projects and raise their costs. Clean energy was the clear winner on the day. CNBC reported gains of 4.6% for First Solar and 4.9% for NextEra Energy.
Uranium didn’t get a blue-wave bounce. $URA slipped 1.06%, and Cameco ($CCJ) fell 1.21% on the day it held its third-quarter call. A Zacks recap of the call said Cameco narrowed its 2026 production guidance to 19.5 to 20.5 million pounds. Meanwhile, Crux Investor, citing TradeTech, reported that the long-term uranium contract price hit a record $99 per pound on Oct. 31.
Opinion: Uranium is the oddest chart in this group. The commodity is at a record, and the miners are falling. If data center power demand slows, as the market traded on Wednesday, the nuclear-for-AI premium shrinks with it, even though reactors still need fuel.
Bet #3: Drug pricing, with $LLY and $UNH
You’d expect a Democratic sweep to hit pharma and managed care. It didn’t. Eli Lilly ($LLY) rose 0.61%, and UnitedHealth Group ($UNH) gained 1.22%. Hospitals went much further. CNBC reported that HCA Healthcare rose 10.3% and Centene 12.6%. Not every healthcare name rallied, though: the Reuters wrap had CVS down 12.5%.
Why the calm in pharma? A Trefis analysis argues that the toughest pricing moves already came from a Republican White House. It says drugmakers that signed price deals are exempt from a 100% tariff on patented drugs through January 2029. It also says Medicare pays $245 a month for Zepbound and Wegovy under the Lilly and Novo deals, while patients pay $50, through a pilot that ends in December 2027. A lasting benefit would need Congress, which makes it upside for Lilly rather than risk. Trefis also flags Nov. 30, 2026 as the deadline for Medicare’s next round of negotiated prices, and says Lilly’s Trulicity is on that list.
The real fight could land on insurers and on the deals themselves. KFF Health News reports that Democrats plan to investigate the undisclosed drug-pricing deals tied to tariff relief. They also plan to push to reverse cuts to the ACA and Medicaid. KFF also notes that limits on pharmacy benefit managers have support from both parties.
Opinion: For $UNH, more Medicaid and ACA money is a tailwind, but PBM reform is the knife. For $LLY, the obesity-coverage pilot could turn into the best bipartisan deal of 2027, or a hostage in the next budget fight.

From the Proprietor
Opinion: Everyone set up for the textbook trade: Democrats win, so sell pharma, buy green, fight tariffs. The tape had other ideas. Pharma shrugged, insurers rose, chips sank on data center politics, and oil got crushed by a war narrative. The lesson is to stop trading the party label and trade the specific lever each party can actually pull. In this Congress, that means subpoenas, budgets and permitting, not tariffs.
What to watch
- Nov. 30, 2026: Medicare’s next list of negotiated drug prices (per Trefis), including Lilly’s Trulicity.
- Texas data center policy under the incoming governor: watch $SMH and power names.
- Iran-war diplomacy and oil: $XLE and $XOP are trading on peace odds now.
- Any bipartisan permitting bill: watch $URA, $CCJ and the utilities.
- Uncalled Senate races in Alaska and Mississippi (per Reuters and NBC News).
