The Globe and Mail reports in its Wednesday, Nov. 26, edition that Cogeco left the INK Canadian Insider Index when the rebalancing took effect on Nov. 21. The Globe's guest columnist Ted Dixon writes that Rogers Communications joined the index. Current index member Quebecor kept its place. Cogeco stock was down 8.6 per cent in the six months leading up to Oct. 31, which was the valuation date for the rebalancing. There was no public market insider activity over that time. Negative price momentum and the reticence of insiders to increase their interests in the company, even as shares were getting cheaper, were the two key factors at play in pushing Cogeco out of the index. The factors working against Cogeco's index membership have been helping Rogers Communications. In the six months leading up to Oct. 31, Rogers Class B shares were up 52.7 per cent, and executive chair Edward Rogers spent more than $45.8-million buying stock in the public market. Rogers's adjusted earnings attributable to shareholders were $1.37 per diluted share, off 4 per cent from the comparable period a year earlier. Despite the profit dip, investors seemed encouraged to hear that Rogers also reaffirmed its full-year 2025 guidance.
