Short Summary
Main recommendation: Investors who want returns above what a diversified stock portfolio offers should use leverage on a well-diversified portfolio rather than concentrate in riskier stocks, but only with strong caution about the downside and behavioral risk. The video argues that borrowing to invest can boost expected returns and, for young investors, improve stock exposure over time, while warning that losses, callable loans, margin calls, and leveraged ETF decay can make results far worse than expected.
Key Points
- Concentrating in the riskiest small, cheap stocks reduces reliability and adds uncompensated company-specific risk, so the video prefers leveraging a diversified portfolio instead.
- Leverage magnifies both gains and losses: a 10% gain on $100,000 borrowed alongside $100,000 of your own cash becomes 20%, but a 50% loss becomes a total wipeout.
- Ayres and Nalebuff (Yale) argue young investors can borrow to invest and gradually reduce leverage, gaining more consistent stock exposure over their lifetime.
- Leveraged ETFs are designed to match a multiple of an index's return only over a single day, so volatility and daily resets can erode long-term returns, and they carry higher costs.
- Behavioral risk is the biggest challenge: leverage amplifies the tendency of investors to sell at the worst times.
Details Worth Noting
- Concrete instructions:
- Start with a well-diversified portfolio you consider optimal for risk-adjusted returns before considering leverage.
- If borrowing, prefer the cheapest secured debt: a home equity line of credit or traditional mortgage against a home with significant equity. Be aware the home equity line of credit is callable and the bank can change its terms at any time.
- Avoid unsecured lines of credit, as the video says their interest rate is likely to be too high relative to expected return for investing in a diversified portfolio. Do not use a credit card for a leveraged investment.
- If using a margin account, understand that a margin loan is limited to a set percentage of the account (example given: 50%). If the portfolio falls past that limit, you face a margin call and may need to add cash or have investments sold.
- Only borrow to invest in a taxable account with the intention of earning income. The video says interest on such a loan is tax deductible in Canada.
- If using leveraged ETFs, recognize they are built for single-day multiples and expect returns over longer periods to differ from the stated multiple.
- The video's example: a 2x leveraged S&P 500 ETF (SSO) has a 0.90% expense ratio, roughly 10 times an unlevered S&P 500 ETF like SPY.
- Research cited includes Frazzini and Pedersen (2011), finding high embedded leverage assets have lower expected returns, and Avellaneda and Zhang (2010), linking leveraged ETF time decay to the variance of the underlying asset.
- The speaker stresses that leverage can work for a young investor only if they can stay invested through a total wipeout, and recommends proceeding with caution.
Bottom Line
Leverage can raise expected returns on a diversified portfolio, but its losses, debt terms, margin rules, and leveraged ETF decay make it risky, and it is only sensible for investors who can stay invested through severe declines.
