The next chart is a Daily ratio chart comparing the Shanghai Index with the S&P 500 Index. What I notice is that price on the Shanghai Index has held up a bit better than the S&P 500 inasmuch as the SSEC began to rally in late September, while the SPX has been in a slow decline since then. Price has not made a new low for the year on this ratio chart.
The next chart is the same ratio chart, but with the RSI, MACD, and Stochastics indicators added. As with the first chart, these indicators are still in decline, and the MACD histogram's decline is still accelerating...signs of recent comparative weakness of the SSEC to the SPX.
The 1-year percentage comparison chart below shows the net gains to date on the SPX versus the net losses on the SSEC.
The next percentage comparison chart below shows the net gains from November 7th to date on the SPX versus the net losses on the SSEC. While the SPX is attempting to rally from its recent lows, the SSEC has continued to decline and make a new (nearly) four-year low in the process. This chart is reflecting the recent comparative weakness of the SSEC to the SPX, as shown on the third chart above.
