Stock Market Muliplier Effect

   With the marvelous performance of the US stock market, I wanted to understand the fundamentals of how it creates wealth. One very simple little example is shown here.
   1) Consider a company that has 100 shares outstanding at a current price of $10. The market capitalization of that company is $1000 (100 * $10).
   2) I want to buy a share in that company and I'm willing to pay $11 for that share. Now the market capitalization of that company is $1100 (100 * $11).
   3) The value of all the shares has increased by $100 although I added only $1.
   4) The stock market has a multiplier equal to the number of shares outstanding!
   5) Most companies have more than a million shares outstanding and a good number have more than a billion shares outstanding.
   6) It still stuns me - if I'm willing to pay $1 more for a share, all the other stockholders feel that the value of each of their stocks have gone up by $1.
   This multiplier effect has an element of a pyramid scheme.
