NEW YORK (TheStreet) -- Last week the Shanghai Composite plunged 13.5%. The reasons cited in media reports include a Chinese crackdown on buying stocks on margin or a huge wave of IPOs. These are two of the four warning flags for stock markets around the world.
Let's explore whether or not the Shanghai Composite is a bubble ready to pop. Then let's look at one of the popular Chinese ETFs to trade, the iShares China Large-Cap ETF (FXI).
Here is the list of serious concerns. These are apparent in the U.S. markets and in some markets around the globe.
- Huge share buyback programs
- A heavy calendar of IPOs
- NYSE margin debt at an all-time high at the end of April
- M&A activity at an all-time monthly record in May
As of the end of May, Chinese companies have raised $29 billion in initial public offerings since the beginning of 2015, vs. $15 billion in the U.S.
In China, margin debt recently reached a record $358 billion at the end of April, which is 3.6% of the stock market cap. In the U.S., NYSE margin debt totaled $507 billion at the end of April -- a record -- but a lower 2.3% of the $22 trillion stock market cap.
Another warning is too much euphoria by individual investors in China. As this bubble inflates, millions of new trading accounts have been opened each week. This number peaked with 1.9 million new accounts opened in May.
The Shanghai Composite did not trade on Monday and had a roller-coaster ride on Tuesday. Last Friday, this index had a close of 4,478.36. On Tuesday the range was 4,264.77 to 4,577.93, with a close of 4,575.12, up 2.2% on the session.
At Tuesday's low, the index was 17.6% below the multiyear intraday high of 5,178.18, set on June 12, but was still up 31.8% year to date. At the close on Tuesday, the loss off the high was cut to 11.6%. This type of volatility is typical of a market in a longer-term topping-out pattern.
Let's look at the weekly chart for the Shanghai Composite, courtesy of MetaStock Xenith.
Looking from left to right, the Shanghai Composite had a parabolic bubble that began to inflate in May 2006 from its 200-week simple moving average, then at 1,397.29. This rise of 338% ended with an all-time intraday high of 6,124.04, set in October 2007.
This popped bubble bottomed at 1,664.93 in October 2008, before the U.S. stock market set its lows in March 2009. The decline for the Chinese index totaled 72.8%, compared to 57.7% for the Standard & Poor's 500 (SPY). The re-inflated bubble for the Shanghai Composite reached a multiyear intraday high of 5,178.18 on June 12, up 211% vs. 220% for the S&P 500. At the recent highs, the Chinese index is 15.4% below its prior bubble peak, while the S&P 500 is 35.5% above its prior peak.
Let's look at the Fibonacci Retracements, which are the horizontal lines on this graph. Notice how 38.2% of the Crash of 2008 was tested at 3,364.65 in July to August of 2009 and not again until January to February 2015. The major portion of the re-inflating bubble has been within the gain of 41.4% year to date. The index has been trading back and forth around the 61.8% retracement of 4,416.92 since the week of April 24.
The weekly chart cannot yet confirm a market top. A close this Friday below its key weekly moving average of 4,556.51 will shift the weekly chart to negative if the momentum reading declines below the overbought threshold of 80.00. This reading is projected to decline to 81.29 this week from 87.82 on June 19.
