Citadel’s Rubner sees stronger setup for US stocks in Q4

US equities achieved record highs in 2023, according to Citadel's Scott Rubner, who highlighted a more favorable framework for the fourth quarter. September's market reset led to a reduction in market excesses, including decreased positioning, leverage, and retail activity, as well as a slowdown in systematic strategies. Rubner emphasized that the starting point for Q4 was materially healthier.

Corporate earnings are the cornerstone of his bullish outlook, with the market transitioning from macroeconomic factors to individual company performance. Earnings estimates have been rising, with corporate profits reaching record levels. The S&P 500's composition reveals extreme concentration, with the top 10 stocks accounting for about 40% of the index.

Despite this, the index can continue to perform as the average stock struggles. Corporations authorized a record $1.3 trillion in buybacks through September, with windows reopening in mid-October and activity expected to pick up in November. By Q3, US equity CTA positioning had shifted more than three standard deviations from heavily long to below neutral, leaving systematic strategies with room to rebuild exposure if price trends stabilize.

Approximately $1.9 trillion flowed into US ETFs year-to-date, surpassing last year's record pace, primarily driven by third-quarter inflows of $771 billion. Mega-cap technology stocks remain buoyed by earnings, index concentration, and passive flows. Rubner suggested that if bond yields decline, sensitive sectors such as small caps, utilities, homebuilders, biotech, and non-profitable technology could experience stronger performance.
