Foolish take
Intuitive Surgical fell by 10% in the three months between June and September. The stock dropped on the back of tariff concerns, uncertainty around Medicaid cuts, and increasing pressure from competitors. It is hard to know, but Abner Herrman & Brock's sale of 30% of its position could have been driven that somewhat lackluster performance.
The firm reduced its holdings during Q3: before Intuitive Surgical's October earnings report which went a long way to reassure investors. The company's Q3 results beat analyst expectations on both revenue and earnings. Numbers of procedures worldwide were up 20% year on year and there's strong demand for its latest da Vinci 5 model.
AHB also slightly pared back its positions in Intuitive's competitors, Stryker (SYK 0.17%) and Abbott Laboratories (ABT +0.19%). It isn't a dramatic shift, but it may show AHB is a little less positive about healthcare technology companies. At the same time, the firm also increased its exposure to big tech stocks like Nvidia, Microsoft, Amazon (AMZN +11.86%), and Tesla (TSLA +2.21%).
