Stocks Are at Record Highs, but Things Will Only Get Harder From Here

Wall Street entered 2024 betting the year would go perfectly, but an up-and-down start for stocks and bonds suggests the going won’t be easy.

Stocks have climbed to records, driven by cooling inflation that has spurred investors to anticipate as many as six interest-rate cuts. Falling rates often boost share prices by reducing the relative appeal of bonds and making it cheaper for companies and consumers to borrow, lifting corporate profits.

But despite Friday’s record close in the S&P 500, the rally in major indexes has stalled in recent weeks—the benchmark index is up less than 2% from where it was a month ago—while the labour market and economy show few signs of slowing. Bond yields have ticked up in the new year after falling sharply at the end of 2023.

This dynamic is prompting some analysts and portfolio managers to warn that further stock gains might be halting because the rate cuts that are widely expected to power the market higher might not arrive as quickly as bullish investors had wagered.

“Clearly, the consensus is that inflation is under control and we’re heading for a soft landing,” said Doug Fincher, a portfolio manager at New York City-based hedge fund Ionic Capital Management. “It’s certainly possible—but a lot of that is priced in.”

The S&P 500 is up 1.5% this year, but analysts see more signs of caution under the hood.

Investors have retreated this year from shares of banks, smaller companies and real-estate firms that posted big gains during the fourth-quarter rally, which was kicked off by investor belief that the Federal Reserve had pivoted in November to a rate-cutting stance. Bond yields, which rise when prices fall, have climbed as traders have pared back bets that Fed officials will start cutting rates in March.

There is a greater than 50% chance the central bank keeps rates where they are at its March meeting, according to the CME FedWatch tool. At the start of the year, traders expected rates to end December around 3.85%. Now they expect closer to 4.1%, per futures contracts tied to the fed-funds rate.

Behind those moves: data showing persistent economic strength that could lift inflation. Treasury yields, a benchmark for borrowing costs, surged last week after Fed governor Christopher Waller cautioned against rushing to cut rates. Yields’ climb continued after data on retail sales, housing starts and unemployment filings all beat economists’ projections. The 10-year U.S. Treasury yield finished the week at 4.145% after starting the year at 3.860%.

Traders are now betting inflation will average above 2.4% over the next five years, the highest level since November, based on swap contracts tied to the consumer-price index.

The Russell 2000 index of small-cap stocks—which gained 22% in the last two months of the year—is down 4.1% in January. Speculative stocks have taken a beating; both Rivian and Coinbase have lost more than 25% after rising during the Fed-pivot rally. A KBW index of regional banks, which added 31% in November and December, has slid more than 3%. Shares of real-estate and utility companies are down even more, also having surged in those months.

The Bloomberg Barclays aggregate bond index, which soared in the final months of last year, is down 1.4% to start 2024.

“People tried to front-run the rate cuts by buying long-duration assets, like tech stocks and bonds,” said Nancy Davis, founder of asset management firm Quadratic Capital Management. “What if the Fed doesn’t cut that much or that quickly? Those people get hung out to dry.”

The Atlanta Fed’s GDPNow model shows the economy likely grew at a 2.4% inflation-adjusted pace in the fourth quarter. That is nowhere near the conditions that have historically necessitated rates coming down 1.5 percentage points—which traders were betting on heading into 2024.

The extra compensation investors receive for buying high-quality corporate bonds over Treasurys is slimmer than before the Fed began raising rates, now around a percentage point. Credit spreads on junk bonds are similarly tight, signalling little concern over company defaults. Leveraged loans—used to fund private-equity buyouts or finance poorly rated companies—are in such high demand that companies are slashing their borrowing costs.

Some investors believe a strong economy could still boost stocks.

Sophia Drossos, an economist and strategist at Stamford, Conn.-based hedge fund Point72, expects robust consumer spending—and a proactive Fed—to help avert a recession and prop up corporate profits. The strong underlying U.S. economy “means risky assets can benefit,” Drossos said.

Not everyone is optimistic. Some fear new sources of inflationary pressure, such as trade disruptions from the Houthi attacks in the Red Sea and a drought in the Panama Canal.

And technical factors also could undermine the market gains. Interest-rate bets often represent investors protecting their portfolios against the risk of a recession or crisis that requires sudden rate cuts. Without a major slowdown, investors might remove those hedges, raising market rates. That could tighten financial conditions and disrupt stocks without any fundamental changes to the economic outlook.

But considering the strength of the economy, many doubt rate cuts will be as aggressive as investors hoped just a few weeks ago, threatening one of the rally’s biggest pillars of support.

“You’d think the wheels would have to come off to see that number of cuts,” said Fincher.

For decades, the world’s computing power has quietly expanded at an astonishing pace.

From the first transistor developed at Bell Labs in 1947 to modern processors containing billions and even trillions of transistors, each generation of technology has been faster, smaller and more powerful than the last.

But according to quantum physicist and technology entrepreneur David Reilly, that era of effortless progress is beginning to slow.

Reilly, CEO of Sydney-based Emergence Quantum and Professor of Physics at the University of Sydney, says the computing infrastructure underpinning modern economies is approaching fundamental physical limits.

And that could have enormous implications for finance, artificial intelligence and global investment.

Speaking at an industry event organised by Kanebridge International, Reilly said many critical parts of modern society depend on computing and the infrastructure used to process information.

The slowdown behind the tech boom

For years, the technology industry relied on a steady improvement known as Moore’s Law, where the number of transistors on a chip doubled roughly every two years.

More transistors meant more computing power, allowing faster software, smarter devices and ever-larger data systems.

Today, however, those gains are slowing.

“It feels to me very innate that I’m going to just find that next year there’s going to be another breakthrough,” Reilly said.

“But if you look at the data…there’s a slowing down, a roll off in performance that started some 10, 20 years ago.”

Rather than making chips dramatically faster, manufacturers are now largely increasing computing capacity by packing more transistors onto each processor.

The approach works, but it comes with growing complexity, higher costs and increasing energy demands.

The brute-force race for AI

That challenge is already visible in the massive data centres being built to support artificial intelligence.

In the race to dominate AI, companies are constructing vast computing facilities that consume huge amounts of electricity and water. Reilly described this expansion as a “brute force” approach driven by the global competition to develop advanced AI systems.

Yet the demand for computing power continues to accelerate.

Artificial intelligence, advanced robotics, healthcare research, pharmaceuticals and cybersecurity all require far more processing capacity than today’s systems can easily deliver.

The question now facing the technology sector is whether traditional computing can keep up.

Enter quantum computing

That is where quantum computing enters the conversation.

Unlike conventional computers, which process information using binary switches that represent ones and zeros, quantum computers exploit the unusual behaviour of particles at the atomic scale.

Reilly describes them as a fundamentally different type of machine.

“So a quantum computer is a wave computer,” he said.

Instead of processing information through simple on-off switches, quantum systems can use wave-like properties of particles to process many possible outcomes simultaneously.

Those waves can interact in complex ways, reinforcing correct solutions while cancelling out incorrect ones. In theory, this allows quantum systems to tackle certain types of problems dramatically faster than classical computers.

What it could mean for finance

The concept may sound abstract, but its potential applications are significant.

Quantum computers are expected to transform areas such as materials science, chemical modelling and pharmaceutical development.

They could also help solve complex optimisation problems in logistics, finance and risk management.

For financial institutions in particular, the technology could offer new tools for detecting fraud, analysing market behaviour and optimising portfolios.

But the shift will not happen overnight.

“One message to take away is that quantum is not going to suddenly solve all of your problems,” Reilly said.

Instead, he said quantum systems will likely complement existing computing technologies as part of a broader and more diverse computing ecosystem.

Why data centres may soon “go cold”

One key change already emerging is how computing systems are physically designed.

Many next-generation technologies, including quantum processors, operate far more efficiently at extremely low temperatures. As a result, future data centres may rely heavily on cryogenic cooling systems to manage heat and energy consumption.

Reilly believes that the shift will gradually reshape the computing industry.

“Over the next five years, you’re going to see data centres go cold,” he said.

“And as that happens, they almost drag with them new compute paradigms.”

Emergence Quantum, the company he co-founded, is focused on developing technologies to support that transition, including cryogenic electronics and integrated hardware platforms designed for quantum computing and energy-efficient systems.

A new technological era

For investors and businesses, the technology remains in its early stages. But the scale of global interest is growing rapidly.

Governments, research institutions and technology companies are investing heavily in quantum research, betting it could become a foundational technology for the next generation of computing.

For Reilly, the moment feels similar to earlier technological turning points.

In the 19th century, new discoveries in thermodynamics helped drive the development of steam engines and the Industrial Revolution. In the 20th century, advances in electromagnetism led to radio, television and eventually the internet.

Quantum physics, he suggests, could represent the next chapter in that story.

“Today we have, as a society, in our hands new physics that we’re just beginning to figure out what to do with,” Reilly said.

“But I think it’s an exciting time to be alive and watch what happens over the coming decades.”
