A Wall Street Journal report cited data from Goldman Sachs and other institutions showing a sharp reset in U.S. equity CTA positioning, with Rubner’s positioning Z-score falling from +2.35 at the end of August to -0.80. The move, more than three standard deviations in a month, suggests previously accumulated long exposure has largely been cleared out. At the same time, U.S. companies have authorized about $1.3 trillion in stock buybacks this year, with some programs expected to resume after October 15 as third-quarter earnings blackout periods end. Historical data also points to stronger buyback activity in November. Rubner’s seasonality data shows the S&P 500 has averaged a 5.6% gain in fourth quarters of U.S. midterm election years since 1930, compared with 2.9% across all years. Tech remains in focus as Nasdaq 100 futures approach 31,200 and the Philadelphia Semiconductor Index trades near record levels. Goldman, Morgan Stanley, and JPMorgan also flagged funding capacity, balance-sheet strength, semiconductor pricing, and AI demand as key factors, while oil remains another major variable for the quarter.

BlockBeats reported on Oct. 3, citing The Wall Street Journal, that data from Goldman Sachs and other institutions shows a sharp shift in CTA positioning in U.S. equities.

According to Rubner research, the positioning Z-score fell from +2.35 at the end of August to -0.80, a swing of more than three standard deviations within one month. The move suggests that previously built-up long exposure has been largely cleared.

At the same time, U.S. companies have authorized about $1.3 trillion in stock buybacks this year. Some of those programs are expected to restart after Oct. 15 as third-quarter earnings blackout periods end. Historical data shows buyback activity usually increases further in November.

On seasonality, Rubner data shows that since 1930, the S&P 500 has posted an average fourth-quarter gain of 5.6% in U.S. midterm election years, above the 2.9% average for all years in the fourth quarter.

In technology shares, Nasdaq 100 futures are nearing the key resistance level of 31,200. The Philadelphia Semiconductor Index has broken through short-term resistance and is approaching historical highs.

Goldman Sachs said bond issuance by hyperscale cloud companies could reach $420 billion by 2027, while interest expense would still account for a relatively low share of earnings. Morgan Stanley data shows those companies have net leverage of about 0.4x, with cash equal to 132% of debt.

Goldman also said pricing expectations for traditional memory and HBM, which had previously been revised down, are starting to recover. JPMorgan said the earnings outlook for semiconductor hardware remains relatively solid, while demand for Taiwan Semiconductor Manufacturing Co. AI accelerators stays strong.

Another major variable for the fourth quarter is crude oil. Goldman said the global oil inventory cushion has thinned materially, and a $100 oil price is not inconsistent with the current supply-demand balance.
