Mad Money Machine

Levered ETFs are Toxic. Here’s Why.

Leveraged Exchange Traded Funds (ETFs) such as FAZ, FAS, and SKF are designed to multiply the DAILY PERCENTAGE change of the underlying index by factors of 2 or 3. They are thus toxic to your wealth and must not be held. Here’s a simple explaination of why. Take the FAS which is the 3X of XLF, the Financials fund. When XLF rises 1% in a day, the FAS is supposed to rise 3%. When things are going your way, everything is fine. But when the XLF drops, very bad things happen to FAS.

Have a look at this table:
FAS vs XLF

On day 1, XLF rose 10% so FAS rose 30%. Great, you’re in the money.

But on day 2, XLF dropped back down to its starting price of $10.00, a decline of 9.09%. The bad news is that FAS declined 3X this amount or -27.27%. This takes its share price down to $9.45 instead of the $10 that you might expect.

So whereas XLF is unchanged after 2 days, FAS is down 5.45% after those same two days.

Why? The power of daily compounding instead of cumulative compounding. The leveraged ETFs are structured in a way that they compound on daily percent changes, not cumulative price changes. The day 2 decline of FAS should only be 23.08% to take it back to its original $10.00 per share price. But because it is 3X of XLF’s daily change, instead it declines 27.27%.

Said another way, the leveraged ETFs operate on the daily percent change not on the price of the underlying index.

Definitely not a buy and hold type of ETF! Not even for one day. Traders: set tight stops!
