Pop Goes the Bubble? Think Of the Sharemarket As a High Chain Letter.

Every time a share is sold, someone else buys it. So the dollars that someone puts into the sharemarket to buy shares equals the amount the ex-shareholders takes out. Suppose there are more people who want to put dollars in than who want to take them out. The potential buyers will have to give an incentive to some shareholders to turn their shares into cash. That inducement is the price of the share going up. So if cash is trying to get into the sharemarket, the prices of shares rise: if cash is trying to get out, they fall. However, in the actual trading the amount of cash that gets in equals the amount that gets out.
