Market consensus has become overwhelmingly bullish, which is precisely the risk signal that most concerns Bank of America.
The latest Bank of America 'The Flow Show' report on fund flows indicates that for the week ending July 8th, global equity funds attracted another $56.6 billion in inflows, with tech fund inflows on pace to set a new annual record. Simultaneously, the bank's Bull & Bear Indicator remained at 9.5, firmly within the extreme optimism zone, with its "sell signal" having been triggered for several consecutive weeks.
Bank of America's chief investment strategist, Michael Hartnett, believes the market is currently betting on "four no's": the US economy will not experience a hard landing, the Federal Reserve will not hike rates, AI capital expenditure will not be cut, and Democrats will not sweep the midterm elections. It is these four consensus points that are supporting the continued rise in risk assets, but a disappointment in any one of them could become the catalyst for a market reversal.
Among all risk indicators, Hartnett specifically highlighted the Japanese market. He argues that Japanese bank stocks remain the "canary in the coal mine" for global risk appetite: if Japanese government bond yields rise further and rapidly, causing bank stocks to weaken, it could signal the start of a correction cycle for global risk assets.
Bull & Bear Indicator Flashing Red: "Everyone is All-In"
Bank of America's Bull & Bear Indicator held at 9.5 this week, well above the 8.0 threshold that triggers a "sell signal." Historical data shows that over the past 24 years, the indicator has issued 17 sell signals, after which the global ACWI index has on average declined 2%-3% over the following 2-3 months, with a hit rate of about 60%. In extreme cases, the maximum drawdown reached 15%-20%.
Examining the sub-indicators, market sentiment appears almost universally at extreme optimism levels: hedge fund positioning is at the 81st percentile; global equity fund flows are at the 88th percentile; bond fund flows are at the 84th percentile; and fund manager positioning has reached the 100th percentile. The only indicator still in neutral territory is global market breadth.
Concurrently, Bank of America's global flow trading model has also maintained a sell signal for eight consecutive weeks.
Global Funds Continue Rushing into Equities, Tech on Track for Record
Capital continues to chase risk assets. For the week ending July 8th, global equity funds saw net inflows of $56.6 billion, marking the fourth-largest weekly inflow this year. Within this, tech funds alone attracted $18.8 billion. If the current pace is maintained, the full-year 2026 net inflow for tech funds could reach $183 billion, setting a new historical record.
Regional fund flows also reflect a recovery in risk appetite: US equity funds regained net inflows of $25.1 billion; Chinese equity funds saw $9.0 billion in inflows, the largest since last December; while European equity funds experienced outflows for the 13th consecutive week. Meanwhile, investment-grade bonds attracted net inflows for the 14th straight week, and bank loan funds recorded their largest weekly inflow since February of last year.
Notably, cash has not exited the market. Money market fund assets have climbed to a new record high of $7.9 trillion, still attracting $39.5 billion in inflows for the week. This suggests significant capital is both chasing risk assets and maintaining ample "dry powder" to await new allocation opportunities.
Japanese Bank Stocks Emerge as Key Global Warning Signal
Compared to US tech stocks, Bank of America is paying closer attention to the Japanese market. Hartnett points out that over the past three years, Japan's 10-year government bond yield has risen from around 0.5% to nearly 3%, while Japanese bank stocks have surged approximately threefold over the same period, becoming one of the world's best-performing sectors.
In his view, Japanese bank stocks effectively reflect the global liquidity and yield environment. If Japanese government bond yields continue to climb rapidly and begin to pressure bank stock performance, this shift could signal a reversal in global risk appetite, serving as an early "canary" signal for a broader global equity market adjustment.
Market Rally Rests on "Four No's"
Hartnett summarizes the current market's optimistic expectations as the "four no's."
First, the US economy will not have a hard landing, implying continued support for corporate earnings and a continued investor preference to "flee bonds, embrace stocks."
Second, the Federal Reserve will not resume hiking rates, at least before the midterm elections, with global central banks overall maintaining a dovish bias. So far this year, global central banks have implemented 34 rate cuts versus 21 hikes.
Third, AI capital expenditure will not be cut. The market consensus expects global tech giants' AI capital expenditure to reach approximately $800 billion in 2026, rising further to about $1 trillion in 2027, which remains a key support for tech stock valuations.
Fourth, Democrats will not sweep the US midterm elections, meaning no drastic changes to fiscal, tax, and other policies.
Consensus Breakage Would Present Contrarian Trading Opportunities
Hartnett also emphasizes that what is truly worth watching is not what the market currently believes, but which consensus points are most likely to be broken.
If the US economy ultimately shows significant cooling, with non-farm payrolls persistently weakening, long-term bonds, defensive consumer staples, high-dividend stocks, and large-cap tech stocks could all begin to outperform the market again.
If the Federal Reserve is forced to resume rate hikes, then the US dollar and yield curve flattening trades would become the primary beneficiaries. Hartnett notes that current US CPI and unemployment are both around 4.2%, a combination that has occurred only a handful of times in the past century and has almost always been followed by rate hikes and market turbulence.
If AI capital expenditure begins to contract, it would directly impact the market's core investment thesis. In that scenario, the software sector and large tech platforms might hold up relatively better, while the Philadelphia Semiconductor Index (SOX) could face greater valuation pressure. Bank of America suggests that narrowing debt financing capacity, deteriorating cash flows, and continued layoffs at tech giants could all be precursors to an AI investment cool-down.
Political risks are also not to be ignored. If Democrats ultimately sweep the midterm elections and Republicans lose control of the Senate, the market might begin pricing in scenarios of constrained fiscal expansion, a weaker US dollar, and declining US Treasury yields.
