Quite nervous Monday trading session in the U.S. stock market led to the positive closing of the major stock indices within a third of a percentage point. On the one hand, not bad corporate reports continued to support the bidders' optimism. On the other hand, the sharp moves of the SEC in the regulation of major crypto-players alerted markets and introduced some instability in the trading dynamics. The Financial and Real Estate sectors were the strongest during the trading session while the Health sector looked like an obvious outsider of the trades.
