When Gold Gaps Up Or Down (Gold Gap Strategy)

Gold gaps up and down a lot, much more than stock indices. Based on the size of the gap in gold, we develop a gold gap strategy.

Previously I have only day traded stocks and traded SPY/ES. Over the last couple of months, I have also had a look at GLD, the ETF that tracks the gold price (GLD resembles the price of gold bullion). I’m not a gold bug, instead, I prefer to invest in real estate to hedge for monetary inflation, but GLD has a low correlation with the stock market and that’s what attracts me.

Because gold is a 24-hour market, and GLD only trades on the exchange in regular hours, there are a lot of gaps up and down. Unlike SPY, it has a tendency to not revert to the mean. A mean reversion strategy is less likely to work on gold than on stocks.

First, let’s look at some characteristics of GLD:

  • c2c: accumulated profits from close to the next days close
  • c20: accumulated profits from close to next days open
  • o2c: accumulated profits from open to close on the same day (daytrade)

The period is from its inception in 2006 until the present. We can clearly see the gain coming from holding overnight, just like you do at night trading in stocks. However, when GLD gaps up significantly and also opens above the high of the last several days, it tends to rise even more during the day towards the close.

Over the whole period, GLD has on average gapped up/down 0.64% (ignoring if it’s up or down). This is quite much and more than double the average gap compared to SPY.

Here is a potential gold gap strategy:

Based on the above we try to construct a gold gap strategy:

  • GLD must open above the high of the last 5 days.
  • GLD must gap up at least 1.5 times the 25 day average of the opening gap.
  • Buy on open, exit on close.

A very simple strategy which gives this result:

P/L in % #fills #wins Avg
25.77379 151 91 0.17

The average winner is 0.58% and the average loser is -0.45%. There are 20 winners above 1% and just 10 losers worse than -1%.

The average gain from open to close over this period is 0.01%, so this is a lot better.

Here is the profit curve:

Actually, GLD has a bigger chance of gapping yet again the next day. On average GLD has gapped up 0.07% over the whole period. The next day GLD has gapped up on average 0.12%, a lot more than average.

The P/L improves if we hold GLD longer, but in my opinion with a lot more at risk. Perhaps holding until the next days open is worth it, it boils down to the risk appetite of the trader. In this case, the average gain is 0.29% per trade.

If we turn it upside down and go short we get this profit curve:

This has been a bull market, so clearly, there is something valuable in this strategy/setup (?).

The above was just an example, but we are confident you can develop many interesting setups by looking at gaps in gold.
