25.06.2019: True to the old stock market saying, “sell in May and go away”, the month of May turned out to be very difficult for the global stock markets. At the beginning of May, a tweet from the US President once again caused problems. Contrary to the general expectation of an early settlement in the trade dispute between the US and China, President Trump threatened to raise again tariffs on certain Chinese imports. China promptly responded with its own tariff increases for US exports to China. As a result, the S & P 500 Index fell 4.5% and Chinese stocks more than 7% at the beginning of May.
