With Bitcoin briefly surpassing $100,000 and the S&P 500 posting its best year since 2019, Bank of America’s strategist warns of a potential market overshoot.

U.S. stocks and cryptocurrencies are showing signs of overheating, with Bank of America Corp.’s Michael Hartnett warning of a potential “overshoot” in early 2025, Bloomberg reports.

The S&P 500’s price-to-book ratio surged to 5.3 times in 2024, nearing a peak of 5.5 seen during the dot-com bubble in March 2000. Hartnett cautioned that if the index approaches 6,666 points — about 10% above current levels — the rally could overextend. Yet, despite this, the bank’s bull-and-bear indicator shows no signs of excessive optimism among global investors, the report notes.

The S&P 500 has gained about 27% this year, which seems to be its best year since 2019. For Bitcoin (BTC), it seems that Trump’s support for crypto fueled optimism and gave confidence to investors seeking gains on risk assets, which helped drive Bitcoin past $100,000 earlier this week. With a market capitalization exceeding $2 trillion, Bitcoin now ranks as the 11th largest economy in the world, Hartnett noted.

The potential for a correction is not only being flagged by traditional market experts. Mike Novogratz, head of digital crypto bank Galaxy Digital, has also expressed caution amid Bitcoin’s surge. He warned that the crypto community is “levered to the gills, and so there will be a correction,” adding that leveraged stocks, such as MicroStrategy, could also experience significant downturns.

Placeholder partner Chris Burniske also urges a cautious approach, advising investors to balance optimism with realism to avoid overhyping market targets. Reflecting on past cycles, Burniske cautioned that Bitcoin’s brief surge past $100,000 may not be sustainable in the short term. He pointed to the 2021 bull market, where inflated expectations fell short, with Bitcoin capping out at $70,000 instead of the anticipated $100,000.
