Prepare to catch as the markets' levitation trick fails

Paul Amery explains how to bet against the market with an inverse exchange-traded fund (ETF) and tips one fund to buy now.

Investors who bet on falling prices get a bad rap. Bullish company executives, motivated by options-based pay, dislike those who query their firms' share prices. Regulators get twitchy whenever the phrase short selling' pops up. And no one likes a nay-sayer. Nonetheless, those betting on periodic declines have history and facts behind them.

Markets can overshoot to the upside as easily as they become undervalued. It's clear that one of the (unspoken) objectives of quantitative easing (QE) is to protect banks by inflating a whole range of asset prices, from government bonds, to shares, to residential and commercial property. If this levitation trick fails, watch out and be ready to benefit.

Inverse exchange-traded funds (ETFs) allow you to profit from a decline in a market index. Their price moves in an inverse direction to that of the benchmark. If you buy an inverse ETF on the FTSE 100 and the index declines 5% in a day, your ETF should rise 5% (or thereabouts inverse ETFs' prices reflect a small adjustment for interest rates and the cost of shorting). Leveraged ETFs work in the same way, but they double (or treble) the daily price change.

The key thing to note about these funds is that they rebalance their index exposure each day. This means that, over longer time periods, you'll find that the return on an inverse or leveraged ETF diverges from the equivalent multiple of the underlying index. The more volatile the underlying index and the higher your leverage factor, the greater the return divergence.

As a result, you shouldn't hold a leveraged fund for more than a day or two. However, simple inverse ETFs (those offering one times the inverse of the index return) suffer much less from this return drift'. So investors shouldn't rule out holding them in accounts that would otherwise be long-only' such as Sipps or Isas.


ETF provider db X-trackers offers the broadest range of inverse ETFs, covering a variety of indices. Not all are heavily traded, so ask your broker to quote a bid and offer (buy and sell) price. An illiquid product will suffer a wide spread. If, like me, you're in the camp of those who think US equities are overvalued, the db X-trackers S&P 500 inverse daily ETF (which I own, LSE: XSPS) is a useful tool.

The firm's inverse trackers for American, British and eurozone government bonds are also worth considering.
