Today, China's Central Bank put 50,000,000,000 RMB ($6.45 Billion) into their market to prop it up. It "only" lost 1.5% so, champagne all around. This, after making it against the law to sell your position for six months if you are a holder of more than 5% of any company. China has been cooking their books for years and their true growth has been nowhere near what they have been advertising. This is now coming home to bite them.
What is true for China, will soon be shown to be true for US "markets". Don't be standing near the exits. Trampling may be a problem.
Just go short and come out ahead.
Not much to worry about except exchange ‘circuit breakers’. And even then just break a law and get a phone call, cover the short and wait for the ride to begin again.
Oh and buy gold of course because gold is so valuable or something.
