The firm holds a broad mix of securities and uses research and analysis to find pricing inefficiencies in individual assets or broad sectors. Omnicom position may not be in its top five, but it is also not an insignificant holding.
Omnicom has struggled this year, in part due to decreased PR spending by governments and businesses. Some analysts see this as a buying opportunity, highlighting solid growth potential. In particular, there's optimism around Omnicom's $13 billion merger with Interpublic (NYSE:IPG). The acquisition has been in the pipeline for some time, but Omnicom recently said it expected to complete by the end of this year.
Omnicom also plans to launch OmniPlus, which leadership describe as a "next-generation marketing operating system." It will use generative AI to analyze and generate insights on campaign performance and consumer behaviors. Rockingstone does not hold positions in other major advertising and communication firms. Opening a position in Omnicom could signal that it sees an opportunity.
