An Important Shanghai Rally Amid Terrible Economic Surprises

An important threshold

When big rallies in the Shanghai Composite failed, fewer than 90% of stocks on the exchange had managed to rise above their 200-day averages. When more than 90% did so, the rallies lasted long-term, at least over the past 17 years. That just happened again.

It’s also been a good sign when the Shanghai Composite rallies at least 30% off its low, especially when it's able to hold its gains over the next couple of weeks.

Optimistic economists

Economists in the U.S. have been too positive about our prospects. Over the past couple of months, economic reports have come in below expectations, to a worsening degree. The Citi Economic Surprise Index just hit “terrible” levels for the first time in years.

The ends of similar streaks have been bad for the dollar and good for the assets that tend to rise when it falls.


The S&P 500 fund, SPY, gapped up and closed at a new 100-day high but well below its open. Of the 14 other times that’s happened, it added to gains over the next four sessions 4 times.

Burst bonds

On March 27 we saw that optimism on bond funds like BND was extremely high, and the Backtest Engine suggested a high likelihood of weak returns over the next week. Now that it has pulled back, the Optimism Index on BND is below 35. Other times it cycled like this, it rebounded the next day all 8 times but was mixed after that, with gains 3 times and losses 5 times two weeks later.
