Morgan Stanley has joined Bank of America in issuing warnings about potential obstacles to a summer stock rally, according to Business Insider. Andrew Sheets, the global head of fixed income research at Morgan Stanley, identified three key risks that could derail the historically strong summer season for equities. The bank noted that July has been the best month for equities since 2014, with the S&P 500 gaining every July since then, but recent market volatility suggests this trend may face challenges.
Bank of America Securities strategist Michael Hartnett has issued a stark warning about current market sentiment, according to the latest Bloomberg fund manager survey. The bank's Bull & Bear Indicator has reached an extreme bull reading of 9.4, which the team advises investors to reduce equity and high-beta exposure. Asset allocators have become extremely bullish, with cash levels falling to an 'uber-low' level of 3.6% of assets from 4.1% last month, representing a typical warning sign for markets. The survey shows global equity allocation increased to a net 42% overweight, from a net 38% last month, with investors adding exposure through healthcare, industrials and consumer discretionary stocks while reducing holdings in energy, communications and consumer staples.
Morgan Stanley identifies Federal Reserve rate hikes as a key risk to the summer rally, with markets pricing in an 82% chance the Fed will hike rates at least once by the end of the year, according to the CME FedWatch tool. As reported by Business Insider, Sheets noted that the idea that the Fed will hold on interest rates steady through the end of the year is a key pillar upholding the bull market. The bank warns that the risk is that this assumption is just wrong, perhaps soon, with markets showing higher expectations for rate increases to combat inflationary pressures.
Morgan Stanley's analysis reveals potential risks to the AI investment boom that has been driving market gains. The bank's base case projects AI investment to rise from around $800 billion in 2026 to around $1.2 trillion in 2027, but warns that second-quarter earnings could show more hesitation to spend due to recent underperformance of AI-focused stocks. The Magnificent Seven stocks, which make up some of the largest AI spenders, dropped 13% from their May peak through their trough in June as investors took profits, with the Roundhill Magnificent Seven ETF now trading relatively flat for the year. The market's most crowded trade is being long semiconductor stocks, according to 82% of investors in the BofA survey, while massive AI capex by hyperscalers is viewed as the most likely source of a credit event by 48% of respondents.
The latest data shows positioning on US equities remains at its highest level since December 2024 at a net 24% overweight, as reported by Bloomberg. However, recent market action reveals the Nasdaq 100 has seen big swings in recent weeks, and is about flat from where it began the second half after a strong second quarter. This volatility comes as investors face a slowdown in AI capex and potential rate hikes from the Federal Reserve, creating a challenging environment for the traditional summer rally that has historically benefited equities. Despite the cautious warnings, 48% of respondents said AI stocks aren't in a bubble, while 61% don't expect an AI hyperscaler to announce a cut to capex this year, reflecting continued investor optimism about AI sector prospects.
