The current stock market is the most dangerous stock market I have seen in my 34+ year career as a financial markets professional. This includes 1987, 1999-2000 and 2007-2008. The run-up in stocks has been largely a product of momentum-chasing hedge fund algos on behalf of the large universe of sophisticated hedge funds which are desperate for performance. In the context of the obviously deteriorating economic fundamentals, the performance-chasing game has become a combination of FOMO – “fear of missing out” – and the Greater Fool Theory – praying someone else will pay more for the stock than you just paid. There’s also likely some official intervention going on as well per the chart below.
