Sentiment on Wall Street is shifting from anxiety to hope. After a pullback driven by concerns over an AI bubble, U.S. equities have rebounded to near record highs. Beyond the continued enthusiasm for AI, a series of key factors are providing momentum for the rally.
Anxiety has given way to hope, a reflection of the current state of Wall Street.
The U.S. stock market has rebounded to near record highs, recovering from a downturn triggered by concerns that the excitement over the artificial intelligence boom had outpaced its potential profits.
Optimism about artificial intelligence has proven resilient. However, other critical factors are also driving the stock market higher. Below are several reasons why investors anticipate this rally may continue further:
Stock valuations may not be as bad as they seem
By some metrics, such as the traditional price-to-earnings ratio, U.S. stocks currently appear very expensive. Even so, these ratios remain below the peaks reached during the internet bubble of the 1990s. Moreover, from other perspectives, stock valuations appear less extreme.
Many Wall Street analysts believe the best way to assess stock value is to compare their yields with those of ultra-safe government bonds. The additional premium reflects the compensation investors receive for holding assets with significantly higher risk.
One widely used version of this metric is known as the 'Excess CAPE Yield,' which takes the average earnings of S&P 500 companies over the past decade and adjusts both those earnings and the yield on 10-year U.S. Treasury bonds for inflation.
As of November, this indicator stood at 1.7%. By historical standards, this is low, suggesting that high stock prices have narrowed the return advantage of equities over bonds. However, this level is not unprecedented and has risen from 1.2% in January, thanks to a cooling labor market and declining yields on 10-year Treasuries driven by the Federal Reserve's renewed interest rate cuts.
Economic growth supports corporate earnings
Ultimately, the performance of the stock market is closely tied to the near-term outlook for consumer spending.
At present, there are indeed some concerns about the U.S. economy. Employment growth has slowed significantly, and the unemployment rate has risen slightly—enough to prompt the Federal Reserve to cut interest rates.
However, investors and economists remain less worried. Many believe that the slowdown in employment growth is largely due to a sharp decline in immigration. Moreover, holiday spending got off to a strong start, and weekly initial jobless claims remain at low levels.
All of this should benefit companies' profit margins. Analysts expect 2026 to be another good year for tech companies, even as they make massive investments in artificial intelligence infrastructure.
Do not follow the tech giants blindly
Tech companies, including NVIDIA, Microsoft, and Meta Platforms, have become such significant components of the S&P 500 Index that any doubts about the future of artificial intelligence could lead to declines not only in tech stocks but also across the entire index.
Nevertheless, the substantial gains of tech giants do not mean poor performance by other types of stocks. The Russell 2000 Index, which reflects small-cap stock performance, hit a record high last week. The equal-weighted S&P 500 Index is also near its historical peak, raising hopes that a tech-centric sell-off would not have catastrophic consequences.
"Tech giants dominate headlines and drive all investment flows and analyses, but other companies are steadily progressing," said Michael Antonelli, market strategist at Baird.
Inflation expectations remain anchored
One ongoing concern for investors is that inflation remains well above the Federal Reserve's 2% target, with the Fed's preferred metric sticking at 2.8% according to the latest reading.
Stubborn inflation may make it more difficult for the Federal Reserve to continue cutting interest rates. If the Fed insists on lowering rates, investors might lose confidence in its commitment to maintaining price stability, sending shockwaves through the markets.
However, investors believe that inflationary pressures are easing. After surging earlier this decade, inflation expectations have stabilized. This can be observed from the spread between nominal government bond yields and Treasury Inflation-Protected Securities (TIPS) yields — a gap on Wall Street known as the breakeven inflation rate.
Improved long-term economic growth prospects
Investors also have a macro-level reason to feel optimistic. Regardless of how the economy performs in the coming months, its health appears much better compared to the more than a decade following the 2008-09 financial crisis.
For years, the Federal Reserve kept short-term interest rates at zero — equivalent to negative real (or inflation-adjusted) interest rates — in an effort to jumpstart stagnant economic growth. Investors and economists had feared a new era of 'secular stagnation' that could harm financially conservative savers and make it harder for the Fed to combat recessions.
The negative yields on 10-year TIPS once indicated that investors expected interest rates to remain extremely low for the foreseeable future. However, these yields have now stabilized at pre-crisis levels.
Analysts attribute this partly to higher inflation and larger federal budget deficits, but also to hopes for stronger economic growth — supported by private sector investments in areas such as artificial intelligence infrastructure and renewable energy.
"For many investors, when real yields are positive, whether investing in equities or fixed income, you will have greater overall investment confidence," said Thanos Bardas, Senior Portfolio Manager and Co-Head of Investment Grade Bonds at Neuberger Berman. "It seems the economy is operating at or above its potential level."
