US Q4 short squeeze conditions are gradually taking shape: CTA positions retreat sharply, $1.3 trillion in buybacks poised to kick in.

BlockBeats news, October 3rd, according to WSJ, data from institutions such as Goldman Sachs show that U.S. equity CTA (trend-following quantitative fund) positioning has recently undergone significant adjustments. Rubner research shows that its positioning Z-score has dropped from +2.35 at the end of August to -0.80, a swing of more than 3 standard deviations within one month, meaning that the long positions accumulated earlier have been clearly unwound.

At the same time, U.S. companies have authorized about $1.3 trillion in stock buybacks this year, and some buyback plans will gradually restart after October 15th as the third-quarter earnings blackout period ends. Historical data show that buyback intensity usually increases further in November.

On seasonality, Rubner data show that since 1930, the S&P 500 has risen by an average of 5.6% in the fourth quarter of U.S. midterm election years, higher than the 2.9% average for the fourth quarter of all years.

On tech stocks, Nasdaq 100 index futures are approaching the key resistance level of 31,200 points, and the Philadelphia Semiconductor Index has broken through short-term resistance and is nearing a record high. Goldman Sachs expects that hyperscale cloud providers' bond issuance in 2027 may reach $420 billion, but their interest expenses as a share of earnings remain relatively low; Morgan Stanley data show that related companies' net leverage is about 0.4 times, with cash at about 132% of debt.

In addition, Goldman Sachs said that previously downgraded pricing expectations for traditional memory and HBM have begun to recover, while JPMorgan pointed out that the profit outlook for semiconductor hardware remains relatively solid, with strong demand for TSMC AI accelerators. Another major variable in the fourth quarter remains crude oil. Goldman Sachs believes that the global crude oil inventory buffer has clearly become thinner, and $100 oil is not inconsistent with the current supply-demand balance.
