Bank of America has issued a warning that the Nasdaq has reached a "bubble threshold," recommending hedging strategies to prepare for a potential pullback.
In a recent weekly report, the bank's derivatives team noted that despite the Federal Reserve's hawkish stance last week triggering a repricing of interest rates, the Nasdaq continued its upward trajectory. Its bubble risk indicator has now climbed to a critical threshold of 0.8, signaling a significant increase in near-term two-tailed risk.
The bank's derivatives strategists believe the momentum in technology trades, centered on artificial intelligence, remains strong. The market's resilience in the face of macroeconomic headwinds and geopolitical uncertainty is described as "precisely the typical characteristic of a bubble building up."
Concurrently, the Nasdaq 100 Index has surged approximately 32% since the end of March, nearly double the gain of the S&P 500 over the same period. This performance is creating valuation pressures that are unsettling some investors.
In response to this market environment, Bank of America recommends a relative value hedging strategy for clients to manage downside risks associated with the AI theme. This involves buying Nasdaq 100 index put options with a $600 strike price expiring in December 2026, while simultaneously selling S&P 500 index put options with an equivalent strike price.
Back-testing data shows this structure generated positive returns during both the 2000 dot-com bubble burst and the significant 2022 market correction, with a profit-to-risk ratio of about 4.3 times.
Bubble Risk Indicator Hits 0.8 Alert Level, Signaling Elevated Two-Tailed Risk for Nasdaq
Bank of America's Bubble Risk Indicator is a price-based quantitative tool. It maps bubble risk onto a continuous scale from 0 to 1 by integrating four dimensions of an asset: return, volatility, momentum, and fragility—where 1 indicates extreme bubble conditions and 0 suggests no bubble signs.
Historical data indicates that major asset bubbles, both during their formation and at their peaks, have been accompanied by high BRI readings.
The Nasdaq's BRI has now risen to the 0.8 level. The bank notes that once this threshold is surpassed, both near-term upside and downside risks increase substantially.
In contrast, while the S&P 500 has also shown resilient gains, its BRI level is significantly lower than the Nasdaq's, indicating a clear divergence in the degree of frothiness between the two indices.
At the sector level, the semiconductor industry is the primary driver behind the Nasdaq's elevated bubble readings. Stocks like Micron, AMD, and Intel rank at the top in BRI scores and carry significantly higher weightings in the Nasdaq 100 compared to the S&P 500.
Bank of America data shows that eight of the top ten US stocks with the highest BRI readings are overweight in the Nasdaq 100, directly contributing to the index's elevated price and volatility performance.
In terms of market themes, US TMT momentum trading, the European semiconductor and memory chip sectors, and Japan's corporate governance reform theme are all representative trading directions globally with currently elevated BRI readings.
Reflexive Market Dynamics Amplify Risks of Chasing Gains
The bank's strategists point out that current reflexive market mechanisms continue to create upside risks for US technology stocks.
Investors are competing to chase momentum while simultaneously fearing missing out on the wealth effects of the AI era. However, sharp corrections are a typical feature of bubble formation, and the associated risks cannot be ignored.
This year, new index rules for the Nasdaq allow large-cap IPOs to be included in the index rapidly, a mechanism not applicable to the S&P 500.
Bank of America believes this gives the Nasdaq a structural advantage over the S&P 500 in capturing AI-related IPOs, a feature likely to be reinforced in the coming months by AI-intensive public offerings.
It is against this backdrop of coexisting upside potential and downside risk that Bank of America advises clients to manage risk using the following combination of tools:
Utilize QQQ call spread options to gain asymmetric upside exposure with limited risk, while avoiding the high premiums of naked options due to rising volatility.
Employ hybrid structures like Nasdaq up/US rates up or Nasdaq up/EUR down, leveraging attractive entry points in implied correlations to achieve approximately 60% cost savings compared to plain call options.
Implement QQQ expanding put spread options, which dynamically reset the protective strike price as the market rises. Adding a "knock-in" condition can further reduce the structure cost by about 50%.
Hold Gamma long positions in stocks with high BRI readings to capture the high realized volatility that typically accompanies such frothy, volatile environments.
The specific hedging trade Bank of America highlights involves buying QQQ put options with a $600 strike price (approximately 14 delta) expiring in December 2026, while selling SPY put options with an equivalent strike price (approximately 9 delta).
The core logic of the strategy lies in the asymmetry of relative value.
The bank notes that at-the-money, the six-month implied volatility spread between QQQ and SPY is already higher than the realized volatility spread over the past three months. However, for out-of-the-money put options, the implied volatility spread between the two is relatively narrow, making downside protection for the Nasdaq more cost-effective relative to the S&P 500.
Historical back-testing supports this logic. An equivalent structure generated positive returns during both the 2000 internet bubble burst and the 2022 major correction, with a profit-to-loss ratio of approximately 4.3 times.
