Is EUR/JPY A Leading Indicator For Stocks (Strategy)? (Backtest, Performance, Setup, Rules)

Traders are always on the lookout for patterns and indicators that can help them predict future stock market returns. The one we are going to present to you today involves the economic relationship between stocks and currencies: is EUR/JPY a leading indicator for stocks?

Why would the EUR/JPY be a leading indicator for stocks?

There is a popular belief that EUR/JPY is highly correlated with stocks, especially European stocks. The basic idea behind it is that whenever the CAC 40, for example, rises, we can probably expect the euro to rise as well, as investors need to get a hand on some euros to buy stocks.

However, whenever the economic situation worsens, or traders are fearful, we usually see investors take their money out of the stock markets, which causes the CAC 40 to drop in value.

Because the Yen is considered to be a safe haven amongst the major currencies, investors sell the Euro and “hide” in the Yen. As a result, EUR/JPY falls.

The idea makes sense, but that is not enough to say it works. Here is the 1-year rolling correlation between a European ETF (VGK) and EUR/JPY:
