Tuesday was the second day in a row when the weakest stocks on a technical basis posted the biggest gains, while some of the highest-ranked issues took it on the chin. Low quality is suddenly back in vogue and high quality is getting sold. Looking at the components of the S&P 100 (OEX), the 20 largest gainers included 10 stocks that are within the lowest 20% for technical ranking. We are using www.stockcharts.com and their proprietary technical ranking (SCTR) to measure strength or weakness. A few more of the biggest daily winners are in the lowest 30% of all issues. About half of the largest winners came from Healthcare and Consumer Staples. Healthcare is the weakest sector in 2025, while both Healthcare and Consumer Staples are the two weakest S&P 500 sectors over the past three months. Out of the 11 weakest stocks in the OEX on Tuesday, eight have SCTRs in the top 20%, most of which were IT stocks, with a couple Industrials thrown in to the mix. Over the past three months, Information Technology has a big lead, with a 35% surge, while Industrials are second, with a gain of 22%. We are seeing the most damage in the hottest industries, including some of the highflying AI stocks, quantum-computing stocks, and drone stocks. Some of these stocks had gone parabolic and a number of them came public recently. So a good dose of profit taking certainly makes sense. The FOMO and YOLO trades are great when they are working, but you better have a finger on the sell button or massive gains can disappear just as fast as they occurred. (Mark Arbeter, CMT)

What do many investors do on the first day of a new quarter? The opposite of what everyone was doing over the past couple of months. They sell the winners (in this case mega-cap Information Technology plays and Utilities that are benefiting from the buildout of AI and data centers) and buy stocks that have been ignored in recent months. On the flipside, the end of a quarter can feature something familiar to any cagey long-term market participant and is called "window dressing," when "smart money" portfolio managers and mutual funds raise their stakes in stocks that have outperformed during the quarter and cut their positions in stocks that have underperformed. In this strategy, the overall holdings in a portfolio look more attractive. The best sector on Tuesday was Materials (XLB), rising 2.6%. Reviewing the technical ranking of the 11 sectors in the S&P 500, XLB sits in the middle. But the industry within the XLB that did the best was paper, which has one of the lowest technical scores possible. Aluminum also had a good day and also has a low technical score. Healthcare (XLV), with a very weak score, was in second place -- and, within the sector, the very weak healthcare providers industry led. Information Technology (XLK) and Communication Services (XLC) were the only two losing sectors and they, of course, have very strong technicals. Semiconductors, with a very high technical score, was the weakest industry in IT, while internet stocks were the weakest as some of the strongest individual stock charts were sold. (Mark Arbeter, CMT)
