Bank of America's Chief Investment Strategist Michael Hartnett, in the latest Flow Show report, presents a seemingly contradictory yet logically consistent market outlook: maintain short-term caution by recommending a retreat from risk assets, but from a long-term strategic perspective, keep a "long stocks, short bonds" allocation. The core logic is that U.S. policymakers view the stock market as a "too big to fail" systemic asset.

On the latest developments, the Bank of America Bull & Bear Indicator has risen from 9.4 to 9.7, reaching its highest level since the meme stock bubble in early 2021, reflecting extreme market optimism.

Meanwhile, Hartnett warns that the credit market is emitting increasingly bearish signals. Credit spreads and CDS for AI hyperscale data center operators continue to widen, while technology stock fund flows have turned net outflows for the first time in six weeks.

For investors, this dual-track judgment of "tactical bearish, strategic bullish" implies: in the short term, rotate towards defensive assets and duration assets, but there is no need to be overly pessimistic about the long-term market outlook—unless a key reversal signal of "rising yields, falling bank stocks" appears.

Bull & Bear Indicator Hits Five-Year High, Overheating Risk Rises

The Bank of America Bull & Bear Indicator has risen to 9.7, its highest reading in nearly five years. This is driven by factors such as massive inflows into high-yield bonds, narrowing spreads on global high-yield and AT1 risk bonds, and improved breadth in global equity indices.

Hartnett points out that historically, whenever the indicator reached similar extremes—whether in 2018, 2020, or 2021—market sentiment often reversed sharply from extreme optimism to extreme pessimism within the following year. He does not assert that history will repeat itself, but clearly warns that this pattern warrants attention.

Looking at this week's fund flows, nearly all asset classes recorded net inflows: cash saw $53.7 billion, equities $32.9 billion, bonds $23.1 billion, gold $0.9 billion, and cryptocurrencies $0.6 billion.

Among these, U.S. equities saw an annualized inflow of $652 billion, a record high, while investment-grade bonds saw an annualized inflow of $527 billion, also a record high.

Short-Term Tactics: Retreat and Rotation, Not Adding Positions

On the short-term operational level, Hartnett clearly states he remains in the "summer retreat/rotation, not adding positions" camp, advising investors to shift from risk assets to defensive assets (such as consumer staples), duration assets (like REITs, small caps, biotech), and the U.S. dollar.

His logic is that these assets are more resilient to tightening financial conditions and, compared to cyclical sectors like banks, industrials, and semiconductors, are less vulnerable to the market's consensus view of "no hard landing, no Fed rate hikes, no AI capex cuts, no Democratic midterm sweep" falling short.

On the macro data front, Hartnett had previously predicted that if July non-farm payrolls exceeded 125,000 and the unemployment rate was below 4.1%, then Fed Chair candidate Kevin Warsh might return to a hawkish stance at the Jackson Hole meeting on August 28. Conversely, if non-farm data fell below 50,000 and the unemployment rate exceeded 4.3%, it would benefit duration assets and defensive allocations.

The final released data showed mixed signals—non-farm payrolls significantly missed expectations, but the unemployment rate fell to 4.1%, partially offsetting the negative impact, although the labor force shrank by 264,000 people during the same period.

Long-Term Strategy: Policy Support Makes Stocks "Too Big to Fail"

From a strategic perspective, Hartnett maintains the core allocation of "long stocks, short bonds," arguing that policymakers have clearly signaled they will not allow a significant stock market decline. He notes that the U.S. economy is highly dependent on the wealth effect—U.S. household stock holdings have increased by $7 trillion so far this year, following increases of $9 trillion in both 2024 and 2025—and the AI data center capital expenditure boom.

Last week's coordinated foreign exchange intervention—aimed at ending what Hartnett calls the "poor man's LTCM" deleveraging event—further confirms this judgment: the U.S. government is always ready to step in to prevent tightening financial conditions from ending the boom and bubbles. He also adds that the Trump administration and Treasury Secretary Scott Bessent still have the yield curve control card to play.

On the earnings front, Hartnett acknowledges that EPS is the core engine of the current bull market, with 12-month forward EPS estimates revised up by 33%. This is partly due to approximately $35 billion in tariff refunds over the past three months, partially offsetting the roughly $75 billion tariff impact between May and July 2025.

Termination Signals and Tail Risks

Despite the long-term bullish outlook, Hartnett clearly identifies the conditions for the current bull market to end: once a "bond vigilante" sell-off event involving "rising yields, falling U.S. dollar" occurs, forcing a sharp fiscal policy pivot and driving asset allocation from stocks to bonds, this boom will come to an end.

For the reversal signal that investors are most concerned about—the "canary in the coal mine"—Hartnett gives a clear answer: "rising yields, falling bank stocks."

In the credit market, he notes that credit spreads and CDS for AI hyperscale data center operators continue to widen, as massive stock buybacks and cash flows are fading. He believes that if MAGS (tech giants) quarterly earnings per share exceed $70, it might eliminate the threat of "cheap computing power from China ending the AI capex boom."

Gold as a Hedge for Political Cycles and Midterm Elections

Hartnett concludes the report by broadening the perspective to a more macro political economy framework.

He points out that the populism of the 2020s has driven fiscal expansion, with U.S. nominal GDP growing from $20 trillion to $32 trillion over the past six years, a 63% increase, while the U.S. national debt is about to break $40 trillion.

In the political landscape, he characterizes the upcoming midterm elections as a battle between "populist capitalism" (reducing deficits through growth) and another political path (reducing deficits through wealth taxes).

In terms of market implications, a Republican hold on the Senate majority would be a positive factor; going long on consumer stocks is the best bet for Trump shifting focus to affordability for the people; and going long on gold is an effective tool to hedge against the tail risk of a "K-shaped" voter structure triggering a simultaneous sharp decline in yields, the U.S. dollar, and stocks by year-end.
