Bubble Battle: China’s Shenzhen Vs. U.S. Tech In 2000

European equity markets were routed Monday after Greece instituted capital controls and declared a bank holiday. Germany’s DAX fell 3.6%, while Italy’s FTSE MIB was down 5.2%. Greece’s stock market will reportedly be closed for at least a week.

Yet despite the attention Europe will receive in the coming weeks, another crisis of greater significance may be taking shape.

In China, stocks are plunging at a breathtaking pace. Monday was particularly volatile. The Shanghai Stock Exchange Composite Index actually opened 2.5% higher, buoyed by China’s benchmark lending rate cut and lowered bank reserve requirement ratios. Gains were fleeting, however, as the Shanghai Composite plunged as much as 7.6% before paring losses to close down 3.3%.

The easing measures announced over the weekend are ostensibly aimed at supporting China’s deteriorating economy. But the timing of the moves suggests a desperate attempt to prop up Chinese equities. The Shanghai Composite was up 60% in 2015 as of June 12, but had suffered a 19% decline just before the interest rate cut.

Some believe China’s extraordinary stock market performance amounts to a speculative bubble. Others probably see a cheap market that got overheated and is poised to head even higher in the coming months.

Either way, the term “bubble” is completely overused nowadays. To figure out what’s going on in China, I compared today’s situation with a classic speculative mania – the U.S. technology-stock bubble.

In March 2000, the NASDAQ Composite Index had more than doubled in just one year and had risen an astounding 500% over five years.

During the tech bubble, the U.S. stock market reached its highest valuation ever. However, in comparing the tech bubble to China’s current situation, I’m only going to select U.S. technology stocks because they were the most egregiously overvalued. I’ll use the very peak of the U.S. stock market on March 10, 2000 as my reference point.

Simply put, the present-day equivalent of the NASDAQ is the Shenzhen Stock Exchange Composite, which has a higher percentage of technology stocks and is slightly smaller in aggregate market cap than its counterpart in Shanghai. As of June 12, 2015, the Shenzhen Composite was up an extraordinary 122% year to date.
