S&P 500 Has More Than Doubled Since Michael Burry’s January 2023 Warning

The S&P 500 has reached another record high, putting the U.S. stock market more than 90% above where it stood when investor Michael Burry posted his now-famous “Sell” warning in January 2023.

The milestone has revived one of the most closely watched debates on Wall Street: how much weight should investors place on the warnings of high-profile market bears, particularly when those warnings arrive years before a major market move actually develops.

The S&P 500 closed at 7,757.64 on Friday, August 7, 2026, setting a new record. The index has gained roughly 90.3% from its January 31, 2023 closing level of 4,076.60, when Burry issued his brief warning.

That means the frequently repeated claim that the S&P 500 is “up more than 100%” since Burry's January 2023 warning depends on how the starting point is defined. From the end of 2022, when the index closed at 3,839.50, the S&P 500 has indeed more than doubled. But measured from the January 31, 2023 close associated with Burry's “Sell” post, the gain is below 100%.

The distinction matters, especially when a market statistic is being used to judge whether a prediction was right or wrong.

Still, the broader story is striking.

An investor who sold the S&P 500 at the end of January 2023 would have missed one of the strongest multi-year advances in the history of the benchmark.

Michael Burry’s “Sell” Warning Became a Market Meme

Burry became famous after his successful bet against the U.S. housing market before the 2008 financial crisis, a story later portrayed in the film “The Big Short.”

His reputation as a contrarian investor has made his public comments particularly influential.

On January 31, 2023, Burry posted a single-word message on social media: “Sell.”

The warning came after the stock market had already staged a powerful rebound from its 2022 lows.

The S&P 500 had gained about 6.2% during January 2023, while the Nasdaq Composite had jumped more than 10%. Investors were increasingly optimistic that inflation was cooling and that the Federal Reserve could eventually slow its aggressive interest-rate increases.

Burry's warning therefore stood out.

But the circumstances surrounding the message were more complicated than the meme that eventually developed around it.

In a later explanation, Burry said his January 2023 message was related to the banking crisis he believed was developing. He had been monitoring banks closely and had held a short position against Silicon Valley Bank.

As the crisis unfolded, several U.S. banks failed or came under severe pressure.

Burry later acknowledged that his “Sell” message had been wrong and said he eventually withdrew the warning after believing authorities had successfully intervened to stabilize the banking system.

That context has frequently been omitted when the original post is discussed online.

The Market Did the Opposite

Instead of collapsing, the U.S. stock market embarked on a remarkable long-term advance.

The S&P 500 recovered from the banking crisis and continued higher through the remainder of 2023.

The rally accelerated in 2024 and continued through 2025 and into 2026, with the index reaching successive records.

By August 2026, the benchmark had climbed to more than 7,700 points.

The latest record close of 7,757.64 represents an extraordinary change from the 4,076.60 level recorded on January 31, 2023.

For investors who interpreted Burry's warning as a signal to exit U.S. equities entirely, the opportunity cost would have been substantial.

The lesson, however, is not necessarily that Burry's concerns were irrational.

It is that market timing can be extraordinarily difficult.

Why the S&P 500 Continued Rising

Several forces helped drive the S&P 500 higher after Burry's warning.

One of the most important was the changing outlook for monetary policy.

The Federal Reserve had spent 2022 and much of 2023 aggressively raising interest rates to fight inflation.

Those rate increases created significant pressure on technology companies, growth stocks and other assets whose valuations depend heavily on future earnings.

As inflation began to moderate, investors increasingly anticipated that the Federal Reserve would eventually move toward a less restrictive policy.

Lower expected interest rates can support equity valuations because future corporate earnings become more attractive when discounted at lower rates.

That helped create an environment in which investors were willing to pay higher prices for stocks.

The Artificial Intelligence Boom Changed the Market

Another major force was the explosive growth of artificial intelligence.

The AI boom transformed investor expectations around technology companies.

Companies involved in semiconductors, cloud computing, data centers and AI infrastructure became some of the strongest performers in the market.

Nvidia emerged as one of the most important beneficiaries.

The company's extraordinary growth in demand for AI accelerators helped propel its market capitalization to historic levels and turned the semiconductor company into one of the world's most valuable corporations.

The AI investment cycle also benefited other major technology companies.

Large firms began spending enormous amounts on computing infrastructure, data centers and specialized chips.

That spending created a feedback loop.

Strong demand for AI infrastructure boosted the earnings of semiconductor and technology companies, which in turn supported the broader market's enthusiasm for continued AI investment.

By 2026, AI had become one of the defining themes of the U.S. equity market.

The S&P 500 Is Not the Same Market It Was in 2023

One reason the headline comparison requires caution is that the S&P 500 is a market-capitalization-weighted index.

That means the largest companies have a much greater influence on its performance than smaller constituents.

As mega-cap technology companies surged, their gains had an outsized impact on the overall index.

The result is that the S&P 500's record performance does not necessarily mean every company in the index has enjoyed similar gains.

Recent market data illustrates the distinction.

On August 7, the S&P 500 reached another record, but only a relatively small number of individual components were simultaneously hitting new 52-week highs during the session.

That does not mean the rally lacks breadth.

It means investors should distinguish between the performance of the overall index and the performance of individual stocks.

Earnings Have Supported the Rally

The market's rise has also been supported by corporate earnings.

Recent reporting indicates that S&P 500 companies delivered exceptionally strong earnings growth during the second quarter of 2026.

Barron's reported that earnings for S&P 500 companies increased by more than 50% year over year during the quarter, with a large majority of companies exceeding analyst expectations.

Strong earnings are important because rising stock prices are easier to justify when companies are generating higher profits.

This has helped distinguish the current market environment from periods in which equity prices rise primarily because investors become more speculative.

Still, strong earnings do not eliminate risk.

Investors continue to debate whether expectations surrounding AI, technology spending and future corporate profitability have become too optimistic.

Burry’s Warning Was Not a Prediction of the Entire 2026 Market

The biggest problem with using today's S&P 500 level as proof that Burry was simply “wrong” is that the January 2023 message was extremely short.

The word “Sell” did not identify a specific price target.

It did not establish a precise time horizon.

And it did not explicitly say that the S&P 500 would collapse.

Burry later explained that the post was connected to the emerging banking crisis rather than being a permanent call for investors to remain out of stocks.

By March 2023, he had changed his view.

He said the banking crisis could resolve quickly and later acknowledged that he had been wrong to issue the original “Sell” message.

That history makes the current comparison more complicated.

The viral version of the story suggests Burry told investors to sell stocks and then watched helplessly as the market doubled.

The actual sequence was more nuanced.

The Cost of Getting the Timing Wrong

Even so, the episode demonstrates one of the biggest challenges facing investors.

A bearish thesis can eventually prove correct while still producing poor investment results if the timing is wrong.

Markets can remain expensive longer than investors expect.

Economic risks can fail to trigger a market decline.

Central banks can intervene.

Corporate earnings can surprise to the upside.

New technologies can create entirely new growth opportunities.

And investor sentiment can remain optimistic despite warnings about valuations.

This is particularly important for long-term investors.

Someone who sells a diversified portfolio because they believe a correction is imminent must eventually make another decision: when to buy back in.

That second decision can be even harder.

If the market continues rising, investors may wait for a correction that never arrives.

Eventually, they may be forced to buy at even higher prices.

The S&P 500’s Record High Changes the Conversation

The latest record high adds another layer to the debate.

At 7,757.64, the S&P 500 is now almost twice the level recorded when Burry issued his January 2023 warning.

From January 31, 2023 through August 7, 2026, the index gained approximately 90%.

From the end of 2022, the gain exceeds 100%.

That distinction should be kept in mind when the statistic is repeated across social media.

The larger point remains unchanged: U.S. equities have performed extraordinarily well since the beginning of 2023.

What Investors Can Learn From Burry’s Warning

There are several lessons investors can draw from the episode.

The first is that even highly respected investors can get market timing wrong.

Burry's success during the housing crisis established a reputation for identifying risks before they become obvious.

But no investor has a perfect record.

The second lesson is that a single market call should not automatically determine a long-term investment strategy.

A portfolio designed around long-term objectives is fundamentally different from a short-term trading position.

The third lesson involves diversification.

The S&P 500 itself provides exposure to hundreds of companies across different sectors, although its largest constituents can dominate returns.

Investors who diversify across asset classes and time horizons may be less vulnerable to the consequences of a single incorrect market forecast.

Valuations Still Matter

The fact that Burry's warning was early or incorrect does not mean investors should ignore valuation concerns.

The S&P 500 remains an expensive asset by many historical measures.

Technology companies command substantial valuations because investors expect continued earnings growth.

AI has created enormous optimism about future productivity and corporate profitability.

But expectations can change quickly.

If AI spending slows, economic growth weakens or corporate earnings fail to meet forecasts, high-valued stocks could face pressure.

This is why the debate around Burry remains relevant.

His warning is not useful simply because he predicted a crash.

It is useful because it raises a broader question: how much optimism is already reflected in today's stock prices?

A Strong Market Can Still Experience Sharp Corrections

Another important point is that a strong long-term trend does not mean markets move upward continuously.

The S&P 500 has experienced numerous corrections throughout the current bull market.

Investors who remained invested have generally benefited from the long-term advance, but they have also had to tolerate periods of substantial volatility.

This is normal for equities.

Markets can fall sharply even during long-term bull markets.

The existence of a record high therefore does not guarantee that the index will continue rising indefinitely.

It simply shows where the market stands today.

Coin Bureau and the Broader Market Discussion

The comparison between Burry's 2023 warning and the S&P 500's subsequent performance has also circulated among financial and cryptocurrency-focused commentators, including Coin Bureau.

The episode has particular relevance for market participants who follow both traditional equities and digital assets.

Crypto investors are often exposed to similar questions about market timing.

Bitcoin and other digital assets can experience extremely large rallies followed by sharp declines, making it tempting for investors to attempt to predict the precise top or bottom.

The Burry episode provides a reminder that even experienced investors can struggle to determine exactly when a major market move will occur.

The Bigger Story Is About Time Horizons

Perhaps the most important lesson from the S&P 500's rise is the difference between a market forecast and an investment strategy.

A trader may believe stocks are overvalued.

A long-term investor may reach the same conclusion but continue holding a diversified portfolio because they cannot know when the market will correct.

Those two positions are not necessarily contradictory.

Markets can be overvalued and continue rising.

They can also fall sharply without warning.

The challenge is determining how much risk an investor can tolerate while remaining committed to a long-term plan.

Burry's January 2023 warning provides a vivid example of what happens when a market call is made at the wrong moment.

The S&P 500 was already recovering from the 2022 bear market.

The banking system appeared fragile.

Inflation remained a major concern.

The Federal Reserve was still fighting price pressures.

From that perspective, there were legitimate reasons for caution.

But markets do not simply price current risks.

They price expectations about the future.

And the future turned out to be much more favorable for U.S. equities than many investors expected.

A Record That Puts an Old Warning in Perspective

The S&P 500's latest record has transformed Burry's 2023 “Sell” message into a historical market case study.

The index has climbed roughly 90% since the January 31, 2023 close associated with his warning and has more than doubled from its level at the end of 2022.

Burry himself later acknowledged that the original warning was wrong, putting the episode into clearer context.

The story is therefore not simply about one investor losing an argument with the stock market.

It is about the difficulty of forecasting markets with precision.

Interest rates changed.

Inflation changed.

Corporate earnings changed.

Artificial intelligence changed investor expectations.

And the U.S. economy proved more resilient than many feared.

Those developments combined to produce one of the strongest market advances of the modern era.

For investors looking back at January 2023, the temptation may be to conclude that the lesson is simply to ignore bearish warnings.

That would be too simple.

The more useful lesson is that even compelling forecasts need a time horizon, a defined thesis and an understanding of what could invalidate the argument.

Markets can move in unexpected directions for years.

And as the S&P 500's journey since January 2023 demonstrates, being early can look remarkably similar to being wrong when investors have to live through the difference.
