Stocks turned in a mixed performance on Thursday, as Broadcom led the Nasdaq lower, the S&P 500 and Dow Jones Industrials were higher, and now all of Wall Street has (maybe) moved on and is awaiting the latest jobs data.

To date, 2026 has been a volatile year for stocks. The major indices started the year by moving higher, but that changed with the onset of the war with Iran on February 28. As oil prices began to climb rapidly, stock prices fell inversely. The Mag7 were out, but now seem to be back in (or at least most of them). AI was in and remains in. Of note, this is President Trump's second year in office, and typically, the second year of a presidency is weak for stocks. Meanwhile, inflation is slowly-and-steadily inching higher again and interest rates haven't budged since the Federal Reserve's last rate cut in December. In 1Q26, the S&P 500 fell 4.3%. In the Argus universe of more than 500 public companies, the average share-price decline was 0.3%, and the median decline was 2%. The following stocks are the top-10 and the bottom-five performers from the Argus universe during 1Q. Among the winners, we note that five are from Information Technology, two from Materials, two from Energy, and one from Healthcare. Why do we study past performance? We want to know which stocks weathered the storms that were presented, the mix of sector performance, and the emergence of new names in the performance derby.

Wall Street is focused on rotation. Mag7 was in, now is out, but remains "in mind" for most investors. So which companies and which sectors are rising to the top so far this year in what has been a volatile start to 2026? We used our Argus screening tool to see which stocks are trading the most above their 52-week low. The sectors and companies that appear below give us clues about which sectors are weathering the current rocky conditions the best, and which might continue to do so if conditions remain challenging. The results show that there has been rotation, but often within the Information Technology sector, as IT remains the group with the most companies represented. Here are the stocks in the Argus coverage universe that are riding the rotation merry-go-round, with the percentage above their 52-week low also noted.
