Questions & Answers

Q: Why is cash considered a poor long-term investment?

Cash is unpredictable in terms of its expected return and has historically been more likely to lose purchasing power compared to stocks and bonds. It offers lower expected returns and does not provide a hedge against falling expected returns.

Q: What is the risk-free asset for a long-term investor?

While many investors consider cash as the risk-free asset, for long-term investors, a long-term inflation index bond is a better option. The stable coupon payments of the bond can offset short-term price fluctuations.

Q: Why do stocks and bonds have higher expected returns than cash?

Stocks and bonds command a risk premium above the return on cash to compensate investors for taking on risk. They are expected to generate higher returns in most environments.

Q: Is it recommended to hold onto cash until a market drop and then invest in stocks?

Buying the dip strategy, holding onto cash until a market drop, generally trails investing a lump sum in stocks. Stocks and bonds have historically shown higher expected returns than cash, making it more beneficial to stay invested.
