Rhumbline Advisers Boosts Stakes in Cummins, Altria, and Fortinet During Q3

Rhumbline Advisers has increased its equity positions in Cummins Inc. (CMI), Altria Group (MO), and Fortinet Inc. (FTNT) during the third quarter. The investment firm raised its stake in Cummins by 3.5%, bringing the total value of its holding to approximately $118.94 million. Additionally, Rhumbline expanded its investment in Altria Group by 1.9%, now controlling more than 2.7 million shares of the tobacco giant. Despite recent insider selling activity at Fortinet, the firm acquired an additional 28,165 shares in the cybersecurity company. These adjustments reflect a broader strategy of institutional portfolio rebalancing based on quarterly performance metrics. While institutional accumulation is typically viewed as a positive signal, these incremental moves are considered lagging indicators of past market activity.
