Definition of Equity Premium Puzzle (EPP)§
The Equity Premium Puzzle (EPP) refers to the paradox whereby historical stock market returns significantly exceed those of supposedly “risk-free” Treasury bills by an estimated 5% to 8%. While this premium should reflect the additional risk investors take on by investing in equities over safe government bonds, its magnitude raises eyebrows and challenges common financial theories. It’s as if investors were once convinced that stocks were like roller coasters: exhilarating and terrifying all at once!
| Equity Premium (EPP) | Risk-Free Rate (Treasury Bills) |
|---|---|
| Excess return received for investing in stocks over T-bills. | The guaranteed return provided by government securities without any risk. |
Examples of the Equity Premium Puzzle§
- If you invested $10,000 in stocks instead of T-bills at a historical equity premium of 6% over 30 years, you might end up with $57,435 in stocks versus about $57,280 in T-bills! 🤑
- Consider a context where risk-averse investors prefer stable returns from T-bills, but given the massive returns from stocks, one must question: Are they actually risk-averse, or just amusingly optimistic? 🤔
