Wall Street Flips to Bullish as Midterm Elections Remove a Key Overhang
TREE NEWS reports: With the US midterm elections now settled and Democrats winning control of both chambers of Congress, major Wall Street trading desks are collectively issuing buy signals to clients. The removal of political uncertainty triggered a sharp market rally: the S&P 500 jumped nearly 2% in a single day, the Dow surged over 3%, and the VIX volatility index posted its largest one-day drop since April 2025. Technology and communication services led gains, while oil prices plunged more than 8% and consumer sectors also performed strongly.
In the wake of the results, JPMorgan, Nomura, HSBC, and Citadel Securities have all published bullish reports with a strikingly consistent thesis: institutional positioning had been heavily reduced ahead of the vote, short interest sat near five-year highs, and seasonal patterns combined with the reopening of corporate buyback windows create favorable conditions for a year-end rally.
Positioning Reset and Short Squeeze Fuel Upside
The core of the bullish case is that investors had already completed a massive de-risking ahead of the election, providing ample "fuel" for a rebound. Hedge funds steadily cut US equity exposure and added shorts before the November vote, with short positions approaching five-year highs; systematic investors also compressed positions in tandem. JPMorgan noted that October's hedge fund deleveraging and AI position liquidation had created a more favorable backdrop for US equities. The bank's US market intelligence team, led by Andrew Tyler, maintained a tactical bullish stance and recommended a "barbell strategy" of tech and cyclical stocks, with a slight tilt toward cyclicals.
Citadel Securities' Scott Rubner wrote in a client note: "With the election over and volatility likely to normalize, there is considerable room for investors to rebuild risk exposure. We believe the path of least resistance for US equities into year-end is higher." Citadel data shows that systematic trend-following strategies (CTAs) currently hold a net US equity position of about negative 3.3 standard deviations, the 10th percentile since 2018 and the lowest since March 31, down sharply from positive 1.7 standard deviations three months ago. Once the market sustains key technical levels, trend-following strategies could trigger systematic buying.
Retail and Buybacks Provide Structural Support
Demand-side signals are also positive, with retail investors and corporate buybacks forming a synergistic effect. Citadel Securities data shows that since October 5, retail investors have net bought US equities for 22 consecutive trading days, accumulating nearly $33 billion—the sixth-longest and fifth-largest buying streak since 2017, with average daily buying 40% above the past year's average. Notably, this buying occurred while the S&P 500 fell about 2% over the same period. Year-to-date, retail net buying has reached $251 billion, surpassing the full-year record set in 2021.
On the corporate buyback front, as the Q3 earnings blackout windows close, buyback demand is returning en masse. Citadel Securities estimates that in mid-October only about a quarter of S&P 500 market cap was in a buyback-eligible state, but by election day that ratio had risen to about two-thirds, and is expected to reach 85% by November 9. As of November 2, new buyback authorizations this year totaled $1.5 trillion, exceeding the previous full-year record. October alone saw $166 billion in new authorizations, more than double the historical monthly average.
Tech Valuations Compressed, Offering Attractive Entry
Beyond technical factors, the sharp contraction in tech valuations is a key basis for institutional bullishness. Citadel Securities data shows the Nasdaq 100's price-to-earnings ratio has fallen to 19.1x, the lowest since October 2022 and a 24% discount to January's peak; relative to the S&P 500, the Nasdaq's premium is just 5%, the lowest since January 2017 and well below the 10-year average of about 20%. Semiconductor valuations have compressed even more dramatically, with the S&P 500 semiconductor constituents' P/E ratio down to 13.8x, a 45% drop from January's peak and the lowest since July 2022, trading at a 25% discount to the S&P 500—the deepest since December 2018.
This valuation reset comes amid continuously upward-revised earnings expectations. Since June 30, forward EPS estimates for memory, AI infrastructure, and semiconductors have been raised by 32%, 31%, and 30% respectively, yet their P/E ratios have compressed by 50%, 36%, and 35%. In the Q3 earnings season so far, 83% of companies have beaten estimates, above the historical average of about 75% and among the top ten strongest readings since 2005. HSBC Chief Multi-Asset Strategist Max Kettner said: "This is not just a repair of October's decline; it's essentially buying everything across the board."
Policy Gridlock May Ease AI Infrastructure Regulatory Concerns
The market has begun digesting the policy implications of Democratic control of Congress, with some investors seeing mixed effects on AI investment. Nomura cross-asset strategist Charlie McElligott noted that Wednesday's rally partly reflected investors unwinding hedges after the election, with VIX futures and the VVIX index both falling sharply, indicating that protective demand built up around election uncertainty and AI worries is rapidly fading.
He wrote that the market believes the election result will lead to "a forced slowdown in US data center construction, thereby easing concerns over an infinite arms race' prisoner's dilemma' in hyperscaler capital expenditures," reducing credit and equity financing pressures needed for the AI boom. Fidelity Global Macro Director Jurrien Timmer also noted that a Democratic blue wave may limit data center expansion, "which could benefit dominant hyperscalers and core members of the 'Mag 7'." JPMorgan strategist Nikolaos Panigirtzoglou cautioned that hedge funds, after a painful October selloff, may need several weeks of market stabilization before rebuilding AI exposure.
Anthropic IPO Seen as Key Catalyst for Full Tech Bullishness
Beyond these multiple positives, institutions are awaiting what is seen as the "ultimate clearing event" for tech sentiment. HSBC's Kettner said: "For me, the real clearing event is the Anthropic IPO. Once the Anthropic IPO is announced and successfully completed, I think that's when you can go fully long tech and sell the defensive assets that rallied sharply in October." The deal is expected to be one of the largest IPOs in history and carries important signaling value for repairing overall tech sentiment.
Historical data also supports a year-end rally. Citadel Securities data shows that since 1950, the S&P 500 has risen in every 6-month and 12-month period following midterm elections, with a median 12-month gain of 14.5%. The fourth quarter of midterm election years is historically the strongest quarter in the US presidential cycle, with the S&P 500 averaging a 5.6% gain versus 2.9% across all years. This year, entering the post-election phase, the market lags the typical midterm-year seasonal trajectory; historically, nearly 60% of midterm-year Q4 lows occur in October, followed by a median gain of nearly 10% into year-end.
Key Takeaways for Investors
- Political uncertainty has been removed, and institutional positioning is light—creating conditions for a year-end rally.
- Retail buying and corporate buybacks provide structural demand support, with buyback authorizations at record levels.
- Tech valuations have compressed significantly even as earnings expectations rise, offering an attractive entry point.
- Gridlock in Washington may ease regulatory pressure on AI infrastructure, benefiting dominant tech platforms.
