Most of the value of the US equity market is held indirectly - through ETFs, mutual funds, pension funds, etc. This suggests that direct ownership is not particularly valued among the vast majority of investors. Have you calculated the size of the market for direct investors who value voting rights? And their patterns of trading?
My question doesn't make that assumption. It questions the size of your target market. You are proposing to "reward" certain investor behaviors but I am suggesting that the numbers indicate that the vast majority place NO value on the reward you are offering.
It seems clear to me that the vast majority of people who have an interest in having exposure to the equity markets do NOT value voting rights.
If more people valued voting rights, then more would hold the stock directly or would only invest through intermediaries who advertise that they behave as shareholder activists. But, comparatively speaking, not many investors do.
