Stock Market Today Live, October 28: Vertiv Soars After Raising Forecast, Enphase Sinks
Vertiv was up 16.2% in pre-market trading at 9:01 a.m. ET after orders at its existing businesses more than doubled and it raised its sales forecast. Enphase was down 20.4% after citing soft home solar demand, higher rates and a lost tax credit, before the Fed’s 2 p.m. decision. Most big movers had news of their own, by our count.
The short answer. Vertiv, Amphenol and other suppliers of data center equipment rose after their own results, while Enphase, Boston Scientific and Logitech fell after theirs. Enphase said higher interest rates and the expired federal tax credit were holding back its core US home solar market. The rate link matters beyond its shareholders because the Fed decides on rates this afternoon, though the Fed cannot bring back the tax credit. By our count, 26 of the 30 stocks on StockTitan’s 9:00 a.m. ET movers board had their own release since Tuesday’s close, while index futures were mixed.

Wendy’s jumps on a reported Trian offer, Amphenol rises and Boston Scientific sinks
Stock index futures were still mixed about 45 minutes before the open, Yahoo Finance reported, with Dow futures lower and S&P 500 and Nasdaq 100 futures higher. The same live page reported, citing The Wall Street Journal, that Nelson Peltz’s Trian Partners has made a takeover offer for Wendy’s. Wendy’s was up 15.6% at 9:01 a.m. ET and has put out no release on StockTitan.
Amphenol, a maker of connectors and sensors, was up 6.8% at 8:58 a.m. ET after record results. Ultra Clean, which supplies parts for chipmaking machines, was up 13.6% at 9:01 a.m. ET after record quarterly revenue.

Its chief executive called this “a challenging year” for the company, which first reported a cybersecurity incident in August. PROG Holdings, a lease-to-own payments company, was down 13.7% after cutting its outlook for the year and saying it is “taking a more cautious view of the consumer.”
8:08 a.m. ET
Flex, ProPetro and Axogen join the gainers as more results land
Stock index futures stayed mixed shortly before 8 a.m. ET, Yahoo Finance reported, with Dow futures lower and S&P 500 and Nasdaq 100 futures higher.
More companies reported before the bell. Flex was up 8.7% at 7:55 a.m. ET after raising its forecast for the fiscal year. ProPetro was up 12.7% at 7:59 a.m. ET after reporting growth at its power generation business. Axogen was up 18.3% at 8:02 a.m. ET after raising its sales forecast for the year.

7:03 a.m. ET
Vertiv soars and Enphase sinks as futures wait on the Fed
Stock index futures were split early on Wednesday, with Nasdaq futures higher and Dow futures lower, Reuters reported, as memory chip stocks rose after SK hynix’s results.
The two largest moves that came with company results were Vertiv’s and Enphase’s. Vertiv was up 16.0% at 7:03 a.m. ET after raising its forecast for the year, and Enphase was down 17.7% after forecasting lower fourth-quarter sales. Logitech and Robinhood also fell after their results; the movers section below has their moves.
The Fed announces its interest rate decision at 2 p.m. ET, at the end of its October 27 and 28 meeting. Reuters reported that expectations lean heavily toward a pause after the Fed raised rates last month.
Biggest stock movers today and why
By 9 a.m. ET, most stocks on StockTitan’s movers board had put out a company release since Tuesday’s close, as more results came out before the bell. For each mover below we give the company’s own news, or say plainly that we found none on StockTitan.
By our count, 26 of the 30 stocks on StockTitan’s live movers board at 9:00 a.m. ET had a company release since Tuesday’s close. At 6:31 a.m. ET it was 9 of 22. With index futures mixed, the morning’s big moves were mostly in single stocks with news of their own.
A release does not prove what moved a stock. NXP and New Oriental fell after reports that give no reason for a fall, and Terrestrial Energy’s only release gave the date of its results. The biggest gainer, Braiin, up 42.6% at 9:01 a.m. ET, had no company news on StockTitan.
LCI Industries, a supplier of components to the recreation and transportation markets, rose after it confirmed an unsolicited cash offer of $101 a share from Monomoy Capital Partners. Its last trade at 9:01 a.m. ET was 4.5% under that offer, by our calculation. LCI’s board still recommends the all-stock merger with Patrick Industries it agreed in June.
Two more companies fell after their reports. Logitech was down 11.4% at 8:50 a.m. ET. Its holiday-quarter forecast includes a $70 million to $80 million hit from an incident that shut a chip supplier’s plant, by the company’s account. The plant opened again in September, and Logitech expects the impact to be largely resolved by its fiscal fourth quarter.
Robinhood was down 5.9% at 9:01 a.m. ET. Its third-quarter report showed crypto revenue down 55% from a year earlier and diluted earnings per share down 16%, while total revenue reached a record.

Why are AI infrastructure stocks up today
Makers of power gear and memory chips for data centers reported big orders or record sales overnight, and their shares rose before the open. TE Connectivity slipped despite higher orders, so the reports did not lift every supplier.
Vertiv makes the power and cooling equipment that keeps data center servers running. Its third-quarter sales rose 61%, and organic orders, which leave out acquisitions and currency swings, more than doubled from a year earlier. Chief executive Giordano Albertazzi said the industry is “in the middle of the largest infrastructure buildout,” and the company put a number on it by raising its sales forecast for the year by $650 million.
At $242.30 at 9:01 a.m. ET, the jump had added about $13.0 billion to Vertiv’s stock market value, by our estimate.
The memory makers moved together. SK hynix said quarterly revenue passed 100 trillion won for the first time, with operating profit equal to 80% of revenue. It expects demand for memory to outrun supply through 2030. Micron was up 3.2% at 9:02 a.m. ET, and Yahoo Finance reported chip stocks kept rising after SK hynix’s report, with Micron and Samsung also higher. We covered the Korean results in our SK hynix earnings article.
Sellers of power equipment and services joined the rally after 7 a.m. ET. Flex expects sales in its Cloud and Power Infrastructure segment, which it plans to spin off, to grow 75% to 85% this fiscal year. ProPetro, an oil and gas services company that also supplies power from natural gas generators, said that power business is negotiating several hundred megawatts of data center work.
Parts makers followed before 9 a.m. ET. Amphenol reported sales up 65% from a year earlier, or 37% leaving out acquisitions and currency swings, and record orders. Its chief executive credited “continued exceptional organic growth in the IT datacom market,” and its shares were up 6.8% at 8:58 a.m. ET. Ultra Clean, which supplies parts for chipmaking machines, reported record quarterly revenue. Its chief executive said the company is positioning itself to gain from the chip industry’s AI-driven growth.
The power grid side reported as well. GE Vernova said third-quarter orders reached $29.3 billion, led by equipment for its Power business, and it agreed to acquire the grid equipment maker Trench Group for $9.0 billion. Its shares were up 0.3% at 8:59 a.m. ET, according to StockTitan real-time Nasdaq data.
Not every supplier rose. TE Connectivity, whose chief executive tied its industrial growth to customers’ AI investments, reported orders up 29%. Its shares were still down 2.1% at 8:56 a.m. ET, in very light trading, according to StockTitan real-time Nasdaq data.
Why are solar stocks down today
Enphase, which makes the small inverters and batteries used on home rooftops, said home solar demand is soft and forecast lower sales. SolarEdge, another solar equipment maker, was down 10.4% at 8:57 a.m. ET, and we found no company release from it on StockTitan since Tuesday’s close.
Enphase said its US revenue rose about 3% from the second quarter, “a smaller than anticipated increase due to soft residential solar demand.”
Its forecast of $225 million to $255 million for the fourth quarter sits below the third quarter’s $293.3 million. The outlook also assumes that sell-through, a sales measure the release names without defining, will be 10% lower than in the third quarter.
Enphase was direct about why its home market is weak. “Our core U.S. residential solar market continues to face headwinds from higher interest rates and the expiration of the Section 25D federal tax credit,” the release said, referring to the federal tax credit for home solar. Higher rates make a rooftop system costlier to finance, and the company named them on the day the Fed decides where rates go next.
