Leverage Magnifies Losses as Well as Gains

Margin and leveraged ETFs increase exposure relative to the money you put in. They magnify losses, add costs and can behave unexpectedly over several days.

Leverage increases your exposure relative to the money you put in. It works in both directions: gains and losses are both magnified.

Buying on margin

Buying on margin means borrowing from your broker. Interest adds to the cost, and the broker may require more collateral or sell your positions, sometimes without contacting you first. You can lose more than your cash deposit.

Leveraged and inverse ETFs

Many leveraged ETFs target a multiple of a benchmark’s daily return. Many inverse ETFs target the opposite of a daily return. Because they reset every day, results across several days can differ significantly from simply multiplying the benchmark’s overall change. Read the particular fund’s objective, because products differ.

Example Consider this example

Suppose an index rises from 100 to 110 and then falls back to 100. It’s back where it started. An idealized daily 2× fund starting at $100 would rise to $120, then lose about 18.18% and end near $98.18. That’s a loss, even though the index finished flat. This example ignores fees and tracking differences.

Three things shape how far a daily-reset fund’s result can drift from the simple multiple.

Volatility — choppy, back-and-forth days tend to pull a daily-reset fund below the simple multiple.
The path of daily returns — the same start and end points can produce very different fund results.
Fees and tracking differences — fees reduce results every day you hold, and tracking differences can push results further from the target.

Watch out

A leveraged ETF isn’t a shortcut to a dependable long-term return. A single-stock ETF also concentrates risk in one company. Beginners don’t need these products to start learning or building a financial plan.

Question 1 of 3 An index falls from 100 to 90, then rises back to 100. An idealized daily 2× fund starts at $100. What is it worth at the end, ignoring fees? Round to the cent.
Your answerdollars
Show answer
Answer: 97.78 dollars (anything within ±0.05 dollars counts).
Day 1: −10% × 2 = −20%, so $100 becomes $80. Day 2: 90 to 100 is +11.11%, and × 2 = +22.22%, so $80 becomes about $97.78. The index is flat, but the fund lost about 2.2%.
Question 2 of 3 When you buy on margin, the most you can lose is the cash you deposited.
TrueFalse
Show answer
Answer: False.
Margin is borrowed money. If prices fall far enough, you can lose your deposit and still owe the broker, plus interest.
Question 3 of 3 What do many leveraged ETFs aim to deliver?
A multiple of the benchmark’s return over any period you holdA multiple of the benchmark’s daily returnA promised minimum returnThe benchmark’s return with less risk
Show answer
Answer: B. A multiple of the benchmark’s daily return
Most target a multiple of one day’s return and reset daily. Over longer periods, results can drift far from the simple multiple. Check each fund’s stated objective.

Key takeaways

Leverage magnifies losses as much as gains.
On margin you can lose more than you deposit, and the broker can sell your positions.
A daily-reset fund can lose money over several days even when its index ends flat.

Key terms

Leverage: Controlling more market exposure than the cash you put up, through borrowing or derivatives like options. It magnifies gains and losses alike.
Margin: Money borrowed from your broker against your account, or the collateral a broker requires for positions such as short options.
ETF (exchange-traded fund): A fund that holds a basket of assets and trades on an exchange like a single stock. SPY, for example, tracks the S&P 500.
