Which Stocks Overreacted To The Midterms?
Part of our midterms guide. Start here: what the vote really changes for your money.
What Does Everyone Already Know?
Democrats won the House and the Senate. The Dow rose about 3% on Wednesday, its best day since April 2025, and the S&P 500 about 1.6%. Underneath, the moves were violent: many health insurers and hospitals jumped about 9% to 13%, AI power stocks fell about 7% to 14%, and defense stocks fell about 3% to 7%. Wall Street’s read: gridlock, with a Democratic tilt.
What Did The Vote Actually Change?
For this year’s earnings, almost nothing. The new Congress takes office on Jan. 3, the President keeps his veto, and Democrats lack a filibuster-proof Senate. Every contract signed, every budget passed and every order booked before Wednesday still stands. So we asked one question of each big mover: what share of its next two years of profit can this result actually reach, and how soon?
| Stock | Move, Wed | Profit the vote can reach | Verdict |
|---|---|---|---|
| Vertiv (VRT) | −13% | under 5% | Overreacted |
| Centene (CNC) | +13% | 0% until a deal | Overreacted |
| Lockheed (LMT) | −7% | under 5% | Overreacted |
| GE Vernova (GEV) | −9% | under 5% | Overreacted |
| Tenet (THC) | +10% | small | Mixed |
| Vistra (VST) | −14% | 10%–25% of 2028 | About right |
| GEO Group (GEO) | about −2% | near 0% for now | Right by the close |
| Oscar (OSCR) | +9% | most, if a deal | Underreacted |
Several of the biggest moves came in the stocks the vote reaches least.
The ranking runs backwards from what you’d expect. GEO Group, whose detention business was the most obvious political target, opened down about 7% and finished down only about 2%. Vertiv, whose order book nobody in Washington can touch, finished near its low of the day.

“Profit the vote can reach” is our rough estimate of the share of each company’s next two years of operating profit that the new Congress, or a newly elected governor, could change, given a veto and a Jan. 3 start. It is a judgment, not a measured figure. Vertiv and GE Vernova: most of 2027 is already in backlog (GE Vernova $197 billion; Vertiv’s orders more than doubled in Q3); only new Texas orders not yet booked are at risk. Vistra: as of August it had sold 94% of its expected 2027 output at fixed prices but about 72% of 2028, so a slower Texas build-out reaches 2028 earnings. Lockheed: contracts already signed stand; Congress can only trim the growth of the $1.5 trillion 2027 request. GEO: the 2025 law already paid for detention expansion; Democrats can’t claw it back past a veto. Centene and Oscar: the vote only helps if Obamacare subsidies come back, which needs the President’s signature and may well wait for the 2027 debt-limit talks. Centene’s marketplace members fell to about 3.4 million from 5.8 million a year earlier, so the subsidy question reaches a smaller slice of its business than it did. Oscar is built around Obamacare plans. Tenet: part of its move follows a strong third quarter and a higher outlook.
Why Did The Most Political Stock Barely Move?
Because by the close the market had done the math. GEO’s detention contracts are funded by money Congress already approved in 2025, and the new Congress can only shape future budgets. GEO had also already fallen 10% in the month before the vote and was 14% below its 52-week high at Tuesday’s close; CoreCivic was down 7% for the month. The fear was priced before Wednesday. GEO reports its third quarter this morning, and that call, not the vote, is the real test of whether contracts are still growing.
What Did Our Data Say Before The Vote?
That many of Wednesday’s movers had already made their political bet. At Tuesday’s close:
| Stock | 1-month return | 12-month return |
|---|---|---|
| Vertiv (VRT) | −6% | +23% |
| Lockheed (LMT) | +26% | +34% |
| Centene (CNC) | +7% | +96% |
| Oscar (OSCR) | +5% | +84% |
| GEO Group (GEO) | −10% | +67% |
| Coinbase (COIN) | −21% | −56% |
| Robinhood (HOOD) | −24% | −42% |
Lockheed’s drop gave back a fraction of a 26% month. Centene’s pop came on top of a near-double.
Vertiv is the cleanest overreaction. It rose 5.2% on election day itself and was already 37% below its 52-week high; Wednesday’s fall took back that rally and more, with no reported change to its orders. Lockheed’s Wednesday loss, about 7%, is small next to the 26% it gained in the month before the vote. Centene was up 96% over 12 months and only about 5% below its high before it jumped again. Coinbase and Robinhood are the opposite case: they were already 54% and 40% below their highs, after the crypto market-structure bill stalled in a 49–50 Senate vote in September. A Democratic Congress could push that bill to 2027 or later, but investors appear to have stopped counting on it weeks ago.
Which Stocks Underreacted?
Fewer than overreacted, and the clearest case is Oscar. Oscar gets most of its business from Obamacare plans, so it has the most to gain if subsidies come back, more than Centene, whose largest business is Medicaid. Oscar rose about 9% on Wednesday, less than Centene’s 13%: the market paid more for the indirect bet than the direct one. Vistra is the other honest case: its fall matched a real change, a Texas governor-elect who wants to pause new data centers, in Vistra’s home state and biggest market. That fall wasn’t an overreaction. It was the market repricing 2028.
What Should You Do This Week?
1. Sort your movers into two lists. For every stock you own that moved 5% or more on Wednesday, write one line: did this company’s earnings change, or only its odds? Most will land on the “odds” list. Those are the ones not to trade on the headline.
2. Use limit orders, not market orders. If a policy pop pushed a position past your target weight, place a limit order to trim back to target at or above Wednesday’s close, rather than selling into Thursday’s open. If a policy drop took a stock you wanted below your planned buy price, place a limit buy at that price and let the market come to you. Say Vertiv was on your list at 20% below its October level: set that limit and walk away.
3. Wait for the numbers that matter. GEO reports this morning; Vistra reports Friday, Nov. 6. Those calls will tell you more about the businesses than Wednesday did. The risk of waiting: a stock that rebounds fast leaves without you. The risk of rushing: you trade a vote that changed nothing in the business.
This is education, not personal advice.
What’s The Bigger Idea?
We call it Sell the thesis, not the price. A price that moves on a vote tells you what other investors now expect; a business that changes tells you something about the company. On Wednesday, the vote moved prices by 10% or more and changed almost no one’s earnings for this year. The investors who act well on days like that ask the same question before every trade: what changed in the business?
Most of Wednesday’s biggest moves were overreactions. Vertiv, GE Vernova and Lockheed fell, and Centene rose, on things the new Congress can’t do before 2027 or without the President. GEO, the most political stock, was right-sized by the close. The one move that matched a real change in earnings was Vistra’s, because Texas power is where the result actually reaches profit, in 2028. We think the Obamacare insurers could give back part of the pop by year-end if no subsidy deal takes shape.
