There’s two parts of how the sale would effect the price. One effect is trust in the business due to it’s shareholders, which could definitely be dealt with yes. The other effect though would be a massive amount of shares entering the market place, which would have purely mechanical outcomes. 30 billion dollars of amazon stock would be about 10 million amazon stock. About 4 amazon stock is traded daily, so that would be 2.5 days of total average amazon stock entering the market over some period of time. This means higher competition between people selling the stock to find people willing to buy it, which would lower the price. The quicker the stock was sold off, the more dramatic this effect would be. 10 million stock also represents about 1/50th of all amazon stock in existence. Another 4/50th’s of that stock also belongs to Bezos. Increasing the amount of stock available to the general populous by a not insignificant amount would also lower the price of the stock, although probably not very dramatically. In the end, those effects probably wouldn’t be too major. I’m actually surprised that so much of amazon’s stock gets traded every day, I wasn’t expecting 4 million stock to be traded daily. Still, it would have an effect that means Bezos couldn’t liquify his position in just a day or two even with a good explanation.
