The main U.S. stock indexes ended Thursday with losses. At closing Dow Jones lost 0.73%, S&P 500 - 0.88%, NASDAQ - 1.02%.

The shares of Alphabet, the parent company of Google, continued their negative trend yesterday after collapsing on Wednesday and reaching 9% during the trading. The reason was the unsuccessful advertising campaign of its new chat-bot, which, according to Reuters, provided incorrect information about historical facts in a video clip. That mistake on Wednesday cost the company $100 billion - investors doubted its success, fearing its lack of competitiveness compared to Microsoft. The latter recently unveiled a similar project that impressed with the accuracy of the chatbot's answers. Yesterday, Alphabet's stock fell more than 4 percent further.

European stock exchanges finished on the plus side, rising 0.33% to 0.96%, buoyed by financial reports from U.S. companies, Prime reported. The growth was not prevented by negative statistics from Germany, which showed an increase in inflation in January to 8.7%.
