10 years of rising fluctuations in global stock prices

If we look back at history, we can confirm that there have been 10 years of upward fluctuations in global stock prices.

1950s: German stock boom
1960s: US stock boom
1970s: Gold boom
1980s: Japanese stock boom
1990s: US dot com stock boom
2000s: BRICs boom
2010s: GAFAM boom

It has been repeated over and over again that a boom is born and then disappeared in a 10-year cycle in the global stock market. This may be because if one theme continues to be bought for 10 years, new buyers will not appear, and institutional investors will begin to relinquish their holdings thinking that no further returns can be expected.

There is also a possibility that people think of 10 years as a break in an era and unknowingly change their investment strategies.

In any case, if we look back on history, there is no such thing as a boom that lasts forever, so I don't think anyone will look at US high-tech stocks, starting with GAFAM, in the future.
