Edward Quince (EQ): Howard, your memos have repeatedly sounded the alarm on the use of leverage, particularly in times of low-risk perception. Why do you characterize leverage as the ultimate two-edged sword?
Howard Marks (HM): Leverage doesn’t add value or make an investment better. It merely magnifies the gains and losses. Volatility combined with leverage equals dynamite. The temptation is clear: leverage is a way to let you bet more than your capital, and it can turn an inadequate 6% return into a handsome 10% on your capital.
EQ: But when it goes wrong, the consequences seem catastrophic, disproportionate even to the original mistake. You’ve used a very vivid analogy to illustrate this downside risk.
HM: That’s right. Levered portfolios face a downside risk to which there isn’t a corresponding upside: the risk of ruin. We must "never forget the six-foot-tall person who drowned crossing the stream that was five feet deep on average”. To survive, you have to get through the low points, and the more leverage you carry, the less likely you are to do so. The presence of debt is precisely what creates the possibility of default, foreclosure, and bankruptcy.
EQ: We see this pattern repeated across crises, from Long-Term Capital Management to recent credit crunches. Why does the market continue to use it excessively?
HM: Leverage pushes routine risks into something capable of producing ruin. When risk aversion is at cyclical lows, people will invest anyway, even if the reward for taking incremental risk is skimpy. Investors often use leverage to try to wring acceptable results from low-return investments. The fundamental risk is that highly leveraged positions are subject to margin calls or can’t bar the door against capital withdrawals, which can lead to a downward spiral of forced selling.
EQ: So, when is the right time to use leverage, if ever?
HM: Leverage should only be used on the basis of demonstrably cautious assumptions. We believe it can be wise to use leverage to take advantage of high offered returns and excessive risk premiums, but it’s unwise to use it to try to turn low offered returns into high ones. The riskier the underlying assets, the less leverage should be used to buy them. Conservative assumptions on leverage will keep you from maximizing gains but possibly save your financial life in bad times.
The Edward Quince Takeaway
Treat leverage as a tool for magnification, not a silver bullet for guaranteed returns. Understand that increased debt narrows the range of outcomes you can endure. Prioritize the security of your capital—and your survival—by maintaining sufficient prudence and adhering to a Margin of Safety, especially when combined with volatile assets.
