Summer or a prime time to withdraw—BofA Hartnett: If Mag7 capital expenditures are cut, broader pullbacks may be difficult to avoid

Author: Wall Street Insights

U.S. Bank’s Chief Investment Strategist Michael Hartnett has once again raised a warning flag. After successfully calling the market bottom in March this year, he said that today’s extremely crowded positioning and bubble-like sentiment have pushed the market into a new high-risk zone, and that exiting risk assets in the summer may be the best move.

Bank of America’s latest survey of fund managers shows that its proprietary “Bull & Bear indicator” has risen to an extreme level of 9.6, the highest in history. Hartnett warned that the optimal summer strategy right now is to “retreat from risk assets and shift to duration, defensive assets, high-dividend stocks, and the U.S. dollar,” rather than adding positions on dips. Meanwhile, he listed the Mag7 ETF (ticker: MAGS) as a key watch item: if MAGS falls below $65, it will drag down the entire cyclicals complex; if it breaks above $70, it would signal a re-entry.

In Hartnett’s view, the biggest tail risk this time is that once mega-cap tech companies announce cuts to AI capital expenditures, and that move fails to lift Mag7 to new highs, “the resulting sharp negative shock to growth and asset prices will catalyze large-scale shorting across banks, broker-dealers, and industrial stocks”—a broad market breakdown.

Extreme positioning triggers warning signal

In his latest “Flow Show” report, Hartnett said Bank of America’s Bull & Bear indicator hit 9.6, the historical extreme, meaning the market is in a state of “extreme positioning.” Under his framework, this signal historically corresponds to the best strategy: avoiding risk rather than adding.

This week’s latest EPFR fund flow data confirms the assessment: equities recorded $55.8B in net inflows, bonds saw $20B in inflows, and money market funds logged $119.6 billion in large-scale net outflows, the biggest weekly outflow since April 2026. Meanwhile, the technology sector posted $48.8 billion in cumulative inflows over the past three weeks, setting a record high; emerging market stocks had $25.0 billion in inflows in one week, the highest since April 2025.

Hartnett admitted that the fund-manager survey itself has almost no direct signal value for predicting market direction, but its value lies in revealing how concentrated current consensus is—providing a reference point for contrarian moves.

Four “no” supports for optimism, but risks are building

The July survey shows that investors’ optimistic sentiment is based on four core assumptions: the economy does not hard-land, the Fed does not hike, AI’s mega-scale capital spending is not cut, and Democrats do not sweep the midterm elections in Congress.

Hartnett describes this combination as “no landing, no hike, no cut, no sweep,” and said this is the fundamental reason the market has almost no short positions left. Expectations for macro prosperity are currently at the highest level since February 2022; bank stocks in the U.S., Japan, the U.K., and Europe have all reached multi-year or even multi-decade highs, which is the most direct expression of the “prosperity trade.”

However, Hartnett believes the logic for a contrarian trade is already in place precisely because everyone is betting on prosperity: go long long-duration Treasuries, defensive assets, and high-dividend stocks, while shorting industrials and banks.

Three contrarian signals broken down one by one

Signal one: 54% expect “no landing”—contrarian buy long Treasuries and defensive stocks.

When the mainstream is betting on a soft landing, or even no landing, Hartnett believes the risk-reward is better for positioning in long-duration Treasuries and defensive sectors.

Signal two: 83% expect the Fed will not hike—contrarian go long the U.S. dollar.

The survey shows 83% of the responding fund managers believe the Fed will not hike before the midterm elections in November, but Hartnett pointed out that U.S. CPI, following the current trend, would rise to 3.9% by the end of 2026 (3-month moving average of 0.3%). At the same time, the Strait of Hormuz is blocked again, and U.S. crude oil inventories are at a 45-year low (only 43 days of supply). And investors’ year-end oil price expectation has slumped from $86 per barrel to $71 per barrel. He believes that if the Fed unexpectedly hikes rates, the best response is still to go long the dollar.

Signal three: 61% expect AI capital expenditure won’t be cut—contrarian short chip stocks.

This is the most crowded consensus trade right now. AI capital expenditure is still growing rapidly, and 61% of respondents think mega-scale cloud computing providers will not announce cuts to capital expenditure before the end of 2026. However, Hartnett noted that the free cash flow of mega-cap firms has started turning negative, while financing pressure in the bond market continues to rise—Oracle credit default swap spreads have risen from 59 basis points in September to 87 basis points, nearing the prior peak. The relative performance of the recent “long MAGS, short SOX” strategy suggests that a cut in capital expenditure may be approaching—or already close.

Semiconductors: crowded positioning, technical pressure

The technical pattern in the semiconductor sector has clearly worsened. The Philadelphia Semiconductor Index (SOX) is currently trading only a 33% premium to its 200-day moving average, down from 76% on June 3—an overbought level exceeded only by the March 2000 technology bubble top. SOX is down 20% from its peak, while the triple-long semiconductor ETF (SOXL) is down 55% from its peak.

Although prices have retreated significantly, there has been virtually no de-risking in terms of positioning. According to Hartnett’s statistics, this week the eight major semiconductor ETFs combined still recorded $2.3 billion in net inflows, bringing cumulative inflows since the start of the year to $46.0 billion, accounting for 31% of assets under management. Over the past three weeks, the tech sector’s total inflows set a record at $48.8 billion; Hartnett described this as “institutional, all-out momentum chasing.”

Capital flows: cash outflows hit a record; clear signs of overheated sentiment

The latest EPFR fund flow data further confirms the market’s extremely optimistic mood. This week, stocks received $55.8B in net inflows, bonds saw $20B in inflows, gold received only $0.50 billion, crypto posted a small net outflow of $0.10 billion, while cash recorded a historic $119.6 billion net outflow—also the largest weekly cash withdrawal since April 2026.

Looking in detail, investment-grade bonds recorded net inflows for the 15th consecutive week, with $9.5 billion in inflows in a single week; emerging market stocks received $25.0 billion in inflows, the biggest since April 2025; technology posted $15.6 billion in inflows in one week, a record for cumulative inflows over the past three weeks; and financials received $2.7 billion in inflows, the biggest since January 2026.

For Hartnett, cash flowing into stocks and technology at this scale is exactly the backdrop behind the Bull & Bear indicator reaching an extreme level—also the core reason he advises investors to stay cautious in the summer and prioritize retreat over adding positions.
