JPMorgan’s trading desk has shifted to a "tactically cautious" short-term outlook, warning markets may become "more volatile" over the next two to three weeks. The desk noted a sharp correction at the index level is unlikely, but more turbulence could hit sectors and individual stocks. On risk factors, it cited lingering Federal Reserve policy risks in September and beyond, adding that positioning signals currently provide no clear direction. Corporate credit bond issuance is likely to pick up again after the Labor Day holiday, and September is historically a month of higher seasonal volatility for U.S. stocks. Based on this assessment, JPMorgan’s trading desk advised investors to reduce net long exposure and consider adopting a market-neutral strategy. The desk explained that in a period of unclear directional calls and dense macro event windows, portfolios should reduce reliance on one-sided upside bets.

Goldman Sachs believes discussions around AI capital expenditure (capex) are far from over. As large tech firms continue to compete for computing power, land, electricity, and data center resources, the supply-demand imbalance in AI infrastructure is likely to persist through the first half of 2028, meaning investors will continue to see higher capex guidance in the coming years. Eric Sheridan, head of TMT research at Goldman Sachs, noted there remains a significant gap between current AI computing power demand and available supply, with storage prices, chip costs, and data center construction expenses all rising. Pressure points across the AI industrial chain have expanded beyond a mere GPU shortage to include memory, land, electricity, data center enclosures, and delivery lead times.
