Key Highlights

● Olin jumped on Friday, October 30, 2026, among S&P MidCap 400 gainers.

● It expects the Huntsman Merger to close in the first quarter of 2027.

● It beat third-quarter profit forecasts.

● Its fourth-quarter outlook came in light.

Olin (NYSE:OLN) jumped on Friday, October 30, 2026, rising sharply by midday, according to market data, and ranking among the gainers in the S&P MidCap 400. The company said it now expects its merger with Huntsman (NYSE:HUN) to close in the first quarter of 2027.

A clearer closing date can matter to investors in a pending merger, because it reduces uncertainty about when the combined company will take shape. Olin's update gave the market that timeline. The company did not,, give new details on the terms of the transaction, so the timing itself was the news.

Results beat, outlook lagged

Olin's third-quarter results also topped expectations. EBITDA came to $191 million, ahead of the $180 million analysts expected, according to market data.

The fourth-quarter outlook was weaker. Olin guided EBITDA for the final quarter of the year to $80 million to $100 million, below the $116 million consensus. The stock moved higher despite the light forecast.

Olin, based in Clayton, Missouri, produces chlor-alkali products and vinyls, epoxy resins, and ammunition through its Winchester brand. Huntsman, based in The Woodlands, Texas, makes specialty chemicals, including polyurethanes and advanced materials.

Materials hold up

Olin's gain came as the materials sector, which includes chemical makers, rose modestly on Friday. Six of the 11 sectors gained, led by energy, consumer staples and utilities, as investors moved money away from technology.

Other chemical stocks had mixed results. LyondellBasell rose after reporting third-quarter Net Income of $758 million, compared with a loss a year earlier, according to market data, while Eastman Chemical (NYSE:EMN) reported results and guidance that trailed forecasts.

A rough day for the market

The broader picture was bleak. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average lost 572.25 points to 51,770.31 and the Nasdaq Composite dropped 747.73 points to 25,437.00, its worst day since June. The Russell 2000 slid 47.37 points to 2,811.84, though small caps finished the week higher.

Intel (NASDAQ:INTC)'s cash-burn warning and Amazon (NASDAQ:AMZN)'s negative trailing free Cash Flow drove a selloff in chip, AI and software stocks. Oil remained above $100 a barrel, with West Texas Intermediate crude settling at $104.12 after reports of tanker incidents near the Strait of Hormuz. Energy costs are a significant input for many chemical producers, and Natural Gas prices fell on the day, settling at $2.883. Gold dropped $132.50 to $3,898.90, a 52-week low.

"The market is much more broad than people generally want to give it Credit for," said an Investment strategist, according to market data. Olin's jump was one example of a stock outside the technology sector moving higher on its own news.

What to watch

The main focus will be the progress of the Huntsman merger toward its expected first-quarter 2027 close, including any regulatory or Shareholder milestones the companies announce. Investors will also watch Olin's fourth-quarter results against its EBITDA guidance range.

Energy prices and industrial Demand will shape the outlook for chemical makers. The October jobs report on Friday, November 6, will provide a read on the economy, and the Federal Reserve's December meeting is in view after this week's hold, with markets leaning toward a hike. The midterm elections on Tuesday, November 3, add another variable for industrial and Manufacturing stocks.
