Leveraged and inverse ETFs: the decay problem

The lesson in plain words

The same lesson as the slides above, written out in full.

1. One day, amplified

Welcome. Leveraged and inverse ETFs look simple on the label, and that is exactly why they trip people up. Today we will walk through how they really work, where the value quietly leaks away, and why we treat them as a caution rather than a holding to keep.

• A leveraged ETF aims to deliver a multiple, often 2x or 3x, of an index's return.
• An inverse ETF aims to move opposite to the index, so it rises when the index falls.
• The promise is a single trading day, not a week, month, or year.
• Both use borrowing and derivatives inside the fund to reach that multiple.
• Understanding the daily reset is the key to seeing the risk.

A quick note: This is financial education only, not financial advice. All numbers are illustrative and simplified to teach the idea. Always do your own research and consider your own circumstances before making any decision.

2. The daily reset

Here is the piece most people miss. The 2x or 3x only applies to a single day, and each morning the fund resets its exposure against wherever the price is now. String several days together and the results compound off shifting bases, so what you get over a week can look nothing like a simple double or triple of the index.

• The multiple is only promised over one day, measured open to close.
• At each new open the fund rebalances so it is 2x or 3x its current value again.
• This means your exposure is calculated off a fresh base every morning.
• Over multiple days the returns compound, and compounding is where paths diverge.
• The label multiple almost never equals the multi-day result you actually earn.

3. Volatility decay

This is the heart of the problem. A 10 percent fall needs about an 11 percent rise to get back to even, and leverage magnifies that asymmetry. So when a market chops sideways, the index can end exactly where it began while the leveraged fund quietly finishes lower. Hold it for weeks in a whippy tape and the drag adds up.

• In a choppy market, a down day then an up day can leave the index flat.
• The 2x fund falls harder first, so it needs a bigger gain just to recover.
• That gap on the way back is volatility decay, and it compounds daily.
• The choppier the market, the more the leveraged fund bleeds versus its multiple.
• Decay works against both leveraged and inverse funds held beyond a day.

4. A caution, not a core holding

Beyond the decay, there is a deeper issue. The leverage inside these funds is funded by borrowing that carries interest, which is a real ethical concern for us. That is why our approach leans on shares you truly own and long options with risk defined from the start, and why a bearish view is expressed through long puts rather than short-selling. Treat leveraged and inverse ETFs as something to understand, not something to hold.

• These funds rely on borrowing inside the wrapper, and that financing carries an interest cost.
• Built-in leverage plus interest raises a clear ethical concern around riba.
• For a bearish view we prefer long put options, never short-selling.
• Our own approach favours defined risk: long options and shares you actually own.
• With those, the most you can lose is known in advance, and there is no daily decay to fight.
