Ever wonder what the ROI would have looked like if you held onto all the post-1983-breakup components of AT&T? Birinyi Associates ran through the numbers, but only after plotting the taxonomy of mergers, divestitures, and acquisitions.
They say it best:
What was once a dominant American long distance telephone company now spans a panoply of wireline, wireless, domestic, international, and cable businesses.
They concluded, after some serious abuse of a Bloomberg terminal, that you have realized a 400% appreciation. The S&P over the same period returned 777%. There is an outstanding question if their analysis took into account dividends and subsequent re-investment of those dividends. I’ll update the post when this becomes clear.
I’m grateful for the analysis, but it really calls for a better graphical representation…. consider the famous map by Charles Joseph Minard that captures the fate of Napoleon’s army in the 1812 campaign. I couldn’t find a high resolution image anywhere, but a copy is available for sale here.
Anyone want to do the same with the taxonomy of mergers, market cap of each component company, and … something else?
