We designed this table to show that even though the underlying index is back to 1,900 in five days, returning 0% in total gain, the ETF is down 1.1% by the end of day 4.
It works like this because ETFs are designed to track daily returns, not mirror longer-term performance of the underlying index, and because of how cumulative returns work. If one share of the ETF costs $100 at the beginning of the period and the market dropped 5%, we should expect double the drop. Our share would now be worth $90. If the next day it reverses and goes up 5%, we should expect double the increase. We would be right in doing so, but our share would be worth $99 now, not $100—because it increased 10% above the $90 closing price the day before.
Leveraged ETFs Are for Traders, Not Investors
If a trader is smart and lucky, she or he would buy the ETF at the beginning of day 3 at $96.43, sell at $109.84, and realize a gain of 14%. But if one bought at day 0 and held until the end of our period, one would lose money even though the underlying index ended up flat.
In general, no one can predict where an ETF will end up because it’s impossible to tell in advance what pattern the underlying index will follow. In practice, it means that an ETF only partially tracks the underlying index; its performance also depends on its own past results.
The ideal case for investing in an ETF (we assume it’s long the market) would be to buy it at the beginning of a multi-day, uninterrupted uptrend. In that case, it would come very close to doubling the market’s performance. But such winning streaks are impossible to forecast, and short-term trading like this is not our focus.
We don’t recommend leveraged ETFs in our portfolio because they’re geared for traders, and we take a longer-term perspective. We are investors.
