Around the World, This Indicator Peaked Last Week

Globalization brings benefits. However, globalization leads to a correlation in stock market movements. Now, there’s nowhere to hide in a bear market.

Globalization brings benefits. Free trade makes more products available to consumers and reduces costs.

However, globalization also increases business cycle correlations. If the United States enters a recession, for example, production of low-cost goods in other countries declines. Now, those countries suffer recessions at the same time as the U.S. Most will also recover at the same time.

Stock market trends reflect business cycles. A growing economy should produce a strong stock market, while economic contractions bring bear markets. Increased globalization led to an increased correlation in stock market movements. Now, there’s nowhere to hide in a bear market.

That makes a recent sell signal in major U.S. and global stock market indexes even more alarming.

Crash Season

At the end of last week, the seasonal trend turned bearish in almost all major market averages around the world.

The chart above shows the seasonal trend of the SPDR S&P 500 ETF (NYSE: SPY). The vertical line on the chart shows where we are now. The trend’s annual peak occurred last week, on July 21.

Seasonal trends are found with mathematical techniques like the Fourier Transform. These same tools have many applications beyond the stock market, like reducing background noise in cellphone calls. So, the math is well-understood and useful.

Seasonal trends are common in financial markets. As one example, a seasonal trend almost completely explains why so many stock market crashes happened in September and October.

Farmers harvest crops in the fall. In the late 1800s, they sold the harvest for cash at local granaries. Crops flowed to markets where grains were processed, usually by rail. Cash changed hands at each stop.

Before computers, banks in the Midwest needed physical cash to start this process. Banks back East sent cash to them, usually at high interest rates. Eastern banks then had little cash since cash was limited under the gold standard of the time.

This was a problem. Wall Street also needed access to cash to function. If Wall Street’s need for cash suddenly spiked while cash was making its way back from the Midwest, the risk of a market crash increased. This often happened.

Market crashes in the autumn of 1903 and 1907 led to calls for change. The Federal Reserve was created to solve this problem.

Markets Around the World

The Fed has solved many problems, but it didn’t completely remove seasonal trends from the stock market. These trends are still visible in markets around the world. And, at the end of July, they sync up in a bearish fashion.

The FTSE All-World Index is shown in the next chart. Charts of major Asian markets along with European and North American markets show a similar trend. Again, the blue line shows where we are now.

Seasonalities are just tendencies. They aren’t absolute rules markets follow precisely. But we know that global stock markets are weak on a seasonal basis for the next two weeks.

This might not be the ideal time to add money to index funds. Only targeted trades based on multiple indicators should be considered in this environment.

    I guess I don’t understand the chart. It looks like the next two weeks are still strong performers and we should be more worried about the last couple weeks in August, or late Oct, or all of Nov. According to how I read both charts, we’re at the begining of declining positive returns, but still among the highest of the year.

    If the world markets are the cat’s moew — which one of the nations are protected when world markets fail? All of them? None of them? One or Two? Come on! If the world markets goes into a recession, all nation’s will suffer.

    I’m sorry it’s taken me so long to respond. With seasonal charts, the important factor is the direction of the trend. When the trend is down, it’s likely that stocks will be weak. When it’s negative, it means we have almost always seen weakness at that time in the past. To be more technical than most people want to read — the chart’s line is the detrended price over time. There are a number of ways to detrend data but the simplest is probably to use log prices and average the log values for a given period (for example the first week of the year, the second week of the year, etc). By removing the trend, we take away upward or downward bias in the price history that’s associated with fundamentals. They should help us see the effect of money flow on price, even if we don’t know the source of the flows. Seasonals should be used as one tool in analysis but they are surprisingly useful. I say surprisingly useful because the trend reversals are known in advance and you’d honestly expect the trend to be arbed away, but it’s not.
