&gt; Can you expand on this? Do you mean the incentive is to push for a constantly higher price because you have to hold on to it?<p>Thinking at a macroscopic level, in an open market, the price of a security isn&#x27;t just &quot;what people are willing to pay for it&quot; (contra great-GP), but rather the balance of what people are willing to sell it for and what people are willing to buy it for. When you prevent one half of that price-discovering mechanism from occurring (selling), you can expect an imbalance -- at least for the market as a whole... for specific, individual companies this may be a second-order effect.
