Get the BookThe Core Thesis
Malkiel introduced the "Efficient Market Hypothesis" to the masses. It states that asset prices reflect all available information. Therefore, it is impossible to consistently "beat the market" because any pattern you find has already been exploited by someone faster than you.
Since you can't beat the market, you should join it. Buy broad-based index funds.
Key Takeaways
- Castles in the Air: Malkiel debunks bubbles throughout history (Dutch Tulips to Dot-coms). Human psychology creates booms and busts, but they are unpredictable.
- Technical Analysis is Voodoo: Looking for patterns in charts ("Head and Shoulders") is pointless. Past price movements do not predict future movements.
- Asset Allocation: Your age should determine your risk. Own more stocks when young, more bonds when old.
⚡ The Lifecycle Plan
Malkiel suggests shifting your portfolio as you age:
- Mid-20s: Aggressive. 90% Stocks / 10% Cash/Bonds.
- Late 30s/40s: Growth. 80% Stocks / 20% Bonds.
- Mid-50s: Balanced. 65% Stocks / 35% Bonds.
- Late 60s+: Income. 40-50% Stocks / 50-60% Bonds/Cash.
