Key Factors

Shiller identifies several structural factors that contributed to the stock market boom from 1995 to 2000 and again from 2002 to 2005:

Capitalist explosion and ownership society – Encouraged stock investing and entrepreneurial spirit
Cultural and political changes – Favored business success and incentivized stock purchases through tax cuts
New information technology – Suggested a new era justifying the stock market boom
Monetary policy and the Feds – Removed perceived risk by intervening in the surging stock market
Perceived effects of the Baby Boomer generation – Influenced political reception and inflated the market
Sureg in Business Medis – Increased interest in the stock market
Overoptimistic analyst estimates – Contributed to inflated stock prices
Growth of defined-contribution pension plans – Increased exposure to stocks
The surge in Mutual Funds – Fed the stock market bubble
Benign Inflation – Created the illusion of wealth and prosperity
Explosion of trade volume – Kept the bid in the bubble
Increase in gambling – Encouraged risk-taking behavior

Conclusion

Financial markets display characteristics of both randomness and patterns. The technical analyst’s (investor’s) job is establishing and maintaining a trading discipline, understanding technical analysis, adapting to changing conditions, and continuously innovating to maintain above-average returns.
