The Financial Post reports in its Tuesday edition that history shows that the global economy and markets move in cycles, not straight trend lines, and contrarian investing is rooted in these patterns. A Financial Times of London, in a look ahead to 2025, says the hot investment theme of one decade typically gets overcrowded, sowing the seeds of its own demise, and does not stay hot the next. Columnist Ruchir Sharma says here we are halfway through the 2020s, and the hot bet of the 2010s -- big U.S. tech -- is still paying off. In the past, the list of global top 10 companies by market cap has changed dramatically with each new decade. Now, seven of the 10 are holdovers from the 2010s, including Apple, Microsoft and Amazon. The trends of the past 15 years are stretched thin amid the growing manias for America and artificial intelligence, which are supercharged by excessive U.S. stimulus, the gamification of investing and the rise of algorithmic trading and passive money managers. Creative destruction has been a defining and necessary feature of capitalism since its roots in the 18th century. Mr. Sharma is betting on a return for contrarian investing, starting with a shift away from the U.S. and its top tech companies.
