The past few weeks have seen technology stocks outperform. Over the past month (at Monday’s closing price), the Nasdaq Composite and Nasdaq 100 tech-heavy indices have gained +5.11% and +5.29% respectively, while the S&P 500 has limited its gains to +3.11% and the Dow Jones to +1.69%.

Recent weeks have brought several positive developments for the technology sector, including the Fed rate cut. Technology stocks usually perform well when interest rates are cut, and the market anticipates the US central bank will implement two more rate cuts by year’s end.

It should also be remembered that massive investments by Nvidia andApple in Intel, whose announcement led to a gain of over 40% for the share over the last two weeks, have boosted many chip industry stocks.

Technology stocks could therefore outperform over the coming weeks, especially as the positive seasonality of Q4, which is about to kick off, also favors an optimistic mood in which tech is used to being particularly comfortable.
