Bell Stock has fallen from $73.41 in 2022, to a low of $43.09 in July, but has since rebounded to 46.95. A lot of the BCE stock story, is an interest rate story. As Interest rates rose, the dividend on BCE became less attractive, and people sold off. When the dividend was 5.4%, and you could get a GIC for the same rate, the stock wasn't very attractive. Now that the yield is 8.5%, and rates are falling, you'll likely see BCE buyers come back to the table.
