Stock Market Bubble

Introduction to Stock Market Bubble

A Stock Market Bubble is a condition in stock market when prices for a stock or an asset rise excessively over a period of time. When a price for an asset outperforms the asset’s intrinsic value, a bubble rises. Basically, speculation is the major drive force to any bubble creation.

When investors are expecting prices to increase, they bid up for the price irrationally to maximize the utility of the market. This behavior lead investors to pay more and more for a security beyond what is expected. Another reason why bubble is created in a stock market is investors’ fear of missing out. When prices are volatile, everyone wants to invest and cash-in. This lead to excessive involvement in stock transaction, more and more people want to buy it, gearing up the prices of assets above its anticipated value.
