Mergers and acquisitions shift ownership from retail to professionals, with risks reversing when deals break. Analyzing AMED, CPRI, and SAVE highlights concentration trends, arbitrage opportunities, and downside risks. This research provides actionable insights into professional ownership patterns during M&A activity and post-deal disruptions.

When M&A deals are announced, ownership changes.

Professionals evaluate these deals and are experts on regulatory issues, deal structures, deal spreads, etc. They translate the deals into returns on capital.

Retail investors often receive a windfall return from the deal but generally do not understand or care about its details. They were long on the company, hoping for a return, which they have now realized.

What typically happens is a migration from retail and non-professional investors to professionals.

When the deal breaks, the process reverses: arbitrageurs (arbs) sell the company, and regular investors buy it. (Example: CPRI, SAVE)

Here are some graphs showing the concentration of ownership after a deal announcement, which shows the institutional ownership.

For AMED, concentration increased when the deal was announced, then fell when the DOJ sued but did not block the deal.

The graph shows that 15% of the company changed hands as a result of the deal. This also gives an indication of how much could be at risk if the deal breaks.

The CPRI graph shows a similar pattern, although that deal actually broke, and the concentration fell by 10%.

Spirit (SAVE) was involved in a three-way deal with Frontier (ULCC) and JetBlue (JBLU), where JBLU became the higher bidder.

The concentration increased with the JBLU deal in July 2022 and then collapsed when the deal fell through in March 2024.

After these two deals collapsed, there were very few professionals remaining in the stock.

In EDR, the concentration jumped with the deal announcement

The change in concentration can be used to estimate the size of the arbitrage position, which is useful for assessing the risks and potential downsides of the deal.

Ownership trends in M&A offer key insights into market behavior and risk assessment. Professionals dominate post-announcement ownership, while deal breaks see a reversal to retail investors. Examining AMED, CPRI, and SAVE reveals how concentration changes highlight arbitrage opportunities and potential downsides, equipping investors to better navigate M&A complexities.
