UBS warns that CTA positioning could sharply amplify any market downturn. With a major U.S. options expiration approaching on Dec. 19, markets are heading into a dense cluster of risk events — the Fed decision on Wednesday, nonfarm payrolls on Dec. 16, and the CPI report on Dec. 18. UBS analysts say that given current positioning and the size of outstanding options, even a small pullback could morph into a much steeper decline. Their analysis shows that a drop in the S&P 500 to around 6,500 — about 5% below current levels — could trigger a critical downside inflection point. UBS’s proprietary model, built to track macro hedge fund behavior around expiration, highlights major sensitivity near 6,850. If the index weakens toward 6,500, commodity trading advisors (CTAs), who follow momentum-driven, algorithmic strategies, would be forced to sell into the decline, accelerating the move lower. The Dec. 19 expiration carries unusually heavy risk, with large open interest at the 5,000, 6,000, 6,850, and 8,000 S&P 500 strikes. Because CTAs rely on systematic trend-following and delta hedging intensifies into expiry, their positioning can significantly exaggerate market swings. December’s expiry is even more consequential because it caps both the quarter and the year. UBS finds CTAs have recently added risk but remain skewed toward selling. A slide toward 6,500 would likely force them to unload increasing amounts of futures to manage directional exposure. In Europe, CTAs are very long Eurostoxx 50 near 5,700, and a move toward 5,600 could trigger heavier selling. UBS also highlights other areas of sensitivity: CTAs are near max short the Japanese yen ahead of the Dec. 19 BOJ meeting, heavily long the Chinese yuan, and holding notable long positions in U.S. 10-year Treasurys that could come under pressure if yields rebound toward 4.25%.

How Homeowners and Buyers Can Still Beat High Mortgage Rates With Two Smart Moves Mortgage rates are rising sharply even though the Federal Reserve is widely expected to cut rates this week — a break from the usual pattern. Typically, when markets anticipate Fed cuts, the 10-year Treasury yield falls, pulling 30-year mortgage rates down with it. This time, the opposite happened. On Monday, the average 30-year mortgage rate jumped nine basis points to 6.36%, its highest level in two weeks, according to Mortgage News Daily. The 10-year Treasury also climbed to 4.17%, signaling that markets aren’t reacting the way they normally do ahead of a rate cut. Jeffrey Ruben, president of WSFS Home Lending, said the 10-year and 30-year yields “are not behaving as they traditionally would,” pointing to two main reasons: Fed Cuts Aren’t Pushing Mortgage Rates Lower The spike in mortgage rates works against the Trump administration’s goal of reducing borrowing costs to revive the housing market. High prices and elevated mortgage rates continue to sideline buyers, while homeowners are still waiting for the right moment to refinance and ease monthly expenses. Despite multiple Fed cuts in 2025, the 30-year fixed mortgage rate hasn’t dipped below 6% all year. Its lowest point was 6.13% in September and October — and it hasn’t been under 6% since February 2023. Two Practical Mortgage Moves You Can Make Right Now Even in this tough rate environment, homeowners and buyers still have options to lower monthly housing costs: 1. Consider an Adjustable-Rate Mortgage (ARM) ARMs offer much lower initial rates compared to 30-year fixed loans. As of Nov. 28, the average 30-year fixed rate was 6.32%, while the five-year ARM averaged just 5.4%, according to the Mortgage Bankers Association. While ARMs carry some risk, they can help buyers secure a lower entry rate. If mortgage rates fall in the next few years, borrowers can refinance into a lower, fixed-rate mortgage later on. 2. Ask Your Lender for a Rate Modification Homeowners can also request a rate adjustment from their lender. A rate modification lowers your existing mortgage rate without refinancing — meaning your loan terms stay the same and your credit isn’t affected. Lenders often agree because it keeps the loan with them rather than losing the borrower to another lender.

Byron Wien, who died in 2023, was one of Wall Street’s most influential strategists. During his long tenure at Morgan Stanley, he became famous for his annual “10 Surprises” list — predictions he believed had better than a 50% chance of happening, even though the market assigned them odds below one-third. Several firms have attempted to continue Wien’s legacy, and U.K. research house Variant Perception has now embraced the tradition for a second straight year, sticking to Wien’s original 50% likelihood vs. 33% consensus framework. Their big-picture view for next year: the economy should hold up reasonably well. Variant Perception expects U.S. nominal GDP to grow more than 5%, a mix of real growth and inflation. Historically, that environment has supported equities, put a floor under yields, and boosted the U.S. dollar — trends already visible over the past two months. This also tends to be the point in the cycle where earlier declines in oil, the dollar, and yields begin to revive manufacturing. Still, despite a constructive macro backdrop, Variant Perception warns that stretched valuations and thin risk premiums in both credit and equities are a challenge. That’s why they favor rotations into emerging markets, value stocks, and other laggards. In their words: there’s a “valuation problem,” not a “macro problem.” Here are their ten surprises for the coming year: The capex story is especially noteworthy. With tariff policies mostly set, bank lending surveys show easier commercial lending standards and stronger loan demand. Corporates may also tap newly favorable tax rules — including full bonus depreciation and immediate R&D expensing. Combined with last year’s declines in oil, the dollar, and yields, these factors typically provide a tailwind for manufacturing. But this rebound may not lift employment. Variant Perception sees similarities to the 2002–2003 era, when productivity gains and easy Fed policy drove a “jobless recovery.” Their oil outlook also deserves attention. While consensus expects a supply glut, the firm believes the balance of risks points to a highly volatile oil market in 2026. They stress that this isn’t contrarian for its own sake — just where the data leads.

Kostin sees opportunities in consumer and healthcare stocks, as well as companies positioned to drive more revenue from AI. Goldman Sachs chief equity strategist David Kostin is set to retire after 31 years, and he’s been inundated with one question on his way out: Is the market in a bubble? His retirement, announced in September, was discussed further in a newly released firm podcast. Ben Snider will succeed him as the firm’s fifth chief equity strategist in more than five decades, while Kostin remains as an adviser. Kostin said that while market analysis has evolved from picking individual winners to selecting groups of stocks based on factors such as balance-sheet strength and global exposure, the core framework is unchanged from 30 years ago: the economy, earnings, valuation, and money flows. “Those are the four legs of the table when identifying opportunities,” he said. For now, Kostin is encouraged by steady VIX levels and a strong third-quarter earnings season heading into 2026. On the question of an AI bubble, he argues that public markets are not in one. Large AI-linked companies trade around 30 times earnings—high, but far below the 40x valuations seen after COVID or the 50x levels of the dot-com era. IPO activity is also far more subdued compared with 1999 and 2021.The private markets, however, tell a different story: rising valuations and vendor financing pressures point to unsustainable pricing. Looking ahead, Kostin highlights several opportunity areas. He sees promise in consumer stocks, noting that middle-income households should benefit from next year’s tax reforms despite concerns about rising unemployment. He also points to healthcare stocks, which are trading at 30-year valuation lows relative to the broader market. Finally, he favors companies that can leverage AI to boost revenue rather than rely solely on cost-cutting. Goldman’s S&P 500 target for next year is 7,600—slightly above MarketWatch’s Wall Street estimate of 7,500.
