Democratic "blue wave" sweeps Congress, and one election rewrites Wall Street's trading logic.
Bank of America chief investment strategist Michael Hartnett, in the latest "Flow Show" weekly report, characterizes the 2026 midterm elections as a historic turning point marking the "peak in AI stock concentration," and lays out a trading list completely opposite to that of the past two years.
Overnight, Three Major "Bullish Convictions" Come Crashing Down
This summer, Wall Street was obsessed with four "won't happens": the Fed won't hike, Democrats won't sweep, AI capex won't be cut, and the economy won't recession.
Reality slapped each one in the face.
Hartnett directly calls it out in the report: "Wall Street's summer bullish convictions were 'no landing,' 'no hikes,' 'no cuts,' 'no sweep.' According to BofA's July global fund manager survey, 70% of investors believed the Fed wouldn't hike before the midterms, 80% believed Democrats wouldn't sweep, and 90% believed AI capex wouldn't be cut."
Now, the Fed already hiked in September, Democrats completed their sweep on Tuesday, and with multiple newly elected Democratic governors pledging to pause data center construction, the conviction that "AI capex won't be cut" is also hanging by a thread.
He says, "The only remaining bullish conviction is the expectation of 'economic boom' — this is the most optimistic moment for fund manager sentiment since February 2022." The implication: this last domino is also on a countdown.
"AI Peak": At the Same Waterline as the Internet Bubble
Hartnett makes the historic significance of this election very clear:
The Democratic tsunami... marks an electoral shift from "populist capitalism" to "populist socialism," with future tax and regulatory direction pointing upward rather than downward (bearish for earnings per share), and 2027 policy will aim to improve affordability and redistribute wealth, which will hit the K-shaped consumption boom, the AI capex boom, and the "too big to fail" Wall Street narrative.
He provides a chart: the market cap share of the top ten AI giants touched a peak of 41% on election night, matching the tech stock concentration during the 2000 internet bubble and only slightly below the historic extreme of 44% in the 1989 Japanese stock market. Hartnett explicitly pins this peak to the 2026 midterm elections.
Hyperscalers: Burning Cash Faster Than Imagined
Supporting this judgment is a set of increasingly ugly financial figures.
Hartnett lists hyperscaler capex and free cash flow projections in the report:
Capex: $239 billion in 2024, $412 billion in 2025, $820 billion in 2026, $1.3 trillion in 2027
Free cash flow: $239 billion in 2024, $191 billion in 2025, negative $63 billion in 2026, negative $252 billion in 2027
Notably, just a week ago, Hartnett's 2027 projections were capex of $1.2 trillion and free cash flow of negative $180 billion. Within seven days, the capex expectation was revised up by $100 billion, and the cash flow gap widened by $72 billion.
Meanwhile, hyperscaler global debt issuance surged from $20 billion in 2024 to $110 billion in 2025, and has already reached $297 billion year-to-date, far exceeding Goldman Sachs' early-year forecast of a $250 billion full-year ceiling.
Hartnett's conclusion: the bond market wants AI capex and issuance pace to slow down. And this is precisely the logic behind suppressing AI "builders" (chips, emerging cloud companies) while ultimately benefiting AI "users'" balance sheets — which is why he wrote "tech bonds outperform tech stocks" in his midterm election trading list.
Chip Stocks: Cheaper, But Not Cheap Enough
The Philadelphia Semiconductor Index (SOX) has now fallen 17% below its 200-day moving average, after having been 74% above it at the peak.
Hartnett points out that since 1996, truly good buying opportunities typically appear when the index is 20% to 25% below the 200-day moving average. In other words, those saying "wait one more hour and buy chip stocks" may need to wait a few more Thursdays.
Nvidia closed Friday at $186.64, and TSMC ADR closed at $375.44, both having broken below the key support levels Hartnett previously identified ($200 and $400).
Biggest Theme: Buy Gold, Wait for the Debt Ceiling Crisis
Hartnett's core macro trade this week points to Washington:
Buy gold... The new Congress is sworn in on January 3, and the U.S. hits the $41.1 trillion debt ceiling on February 1 (based on the current 12-month debt growth rate); in the three months before the 2011 and 2023 debt ceiling political battles, gold rose 12% and 17% respectively.
Currently, U.S. debt stands at approximately $40.5 trillion, with the debt ceiling at $41.1 trillion. With a new Democratic Congress facing a Republican White House, if the historical patterns of 2011 and 2023 repeat, gold starting from around $4,000 could reach the $4,500 to $4,700 range at the peak of the debt ceiling battle.
Midterm Election Trading List
Hartnett's specific directions are:
Gold > oil, falling yields, tech bonds > tech stocks, consumer stocks > energy stocks, small caps > monopoly stocks, long Europe, long Chinese tech stocks
His tactical stance is equally clear: "Maintain risk aversion until three conditions are met: central banks stop hiking (41 hikes in the past six months), the 10-year Treasury yield falls below 4.5%, and oil drops below $80 per barrel."
However, last Friday's nonfarm payrolls data showed 165,000 new jobs, far exceeding market expectations, with the unemployment rate falling to 4.1%. San Francisco Fed President Daly immediately indicated that further rate hikes may be needed, the 10-year Treasury yield closed near 4.85%, and oil prices are still hovering above $90 per barrel. Of the two data conditions Hartnett set, one has already failed, and the other will be decided by this Tuesday's CPI data.
Fund Flows: Record Buying, But Direction Is Already Shifting
In the week ending Wednesday (mainly before Thursday's crash), fund flows showed:
Cash inflows of $140.4 billion, the seventh-largest single-week inflow in history
Global equity inflows of $89.2 billion, with cumulative inflows of $265.6 billion over the past four weeks, a record
Chinese equity inflows of $34.5 billion, with cumulative inflows of $85.9 billion over the past four weeks, a record (the "national team" stepping in)
Emerging market bond outflows of $6.1 billion, the sixth-largest single-week outflow in history
Notably, $317 billion flowed into passive funds over the past four weeks, meaning a massive amount of capital went directly into the top ten AI giants that Hartnett says "already peaked on election night."
Recession "Canaries": One Has Already Fallen
Hartnett sets three recession warning indicators — as long as they hold, the S&P 500 won't crash: the bank ETF (IXG) holds $125, the small/mid-cap ETF (MDY) holds $666, and the high-yield bond ETF (JNK) holds $92.
Currently: IXG is at $130.05, safe; JNK is at $92.70, just $0.70 above the warning line; MDY is at $657.82, having already broken below $666.
Three "canaries," one has already fallen. The S&P 500 is currently less than 1% away from the trigger line (7,323 points) for Hartnett's "global breadth rule" buy signal.
