Summary
The overall smart money picture reveals a nuanced positioning. While institutional ownership remains exceptionally high, there has been a notable reduction in the aggregate percentage of shares held over the past four quarters. Concurrently, the flow analysis indicates a mild accumulation trend, suggesting a potential shift in the composition of institutional holders, where a greater number of funds may be initiating or increasing positions despite a net reduction in the overall institutional stake. This institutional signal, however, diverges sharply from insider activity, which shows significant net selling. The low conviction score further suggests that the stock is not a high-concentration holding for most institutional investors.
