It means absolutely nothing technically, but it does cause a short term spike in value because companies only do this when they are doing extremely well. So it is a confidence check. Small investors can now buy individual shares of the stock and there are some small changes as a result of companies that are part of the Dow Jones, and other stock groupings. In the short term the volatility will likely increase, expect single digit up/down fluctuations every day for a bit. This is all my experience, thoughts, etc. AMZN is a great stock. Most people are not aware of the key assets of the company.
