If you want to talk about the most magical phenomenon of the year in the US stock market, then the "Monday halo" will undoubtedly be on the list. On Monday, the S&P 500 index closed with another positive line - up 0.7%, and the Nasdaq Composite Index, which is concentrated in technology stocks, rose 1.1%. In fact, many Wall Street traders are now accustomed to the rise of US stocks on Monday: before the fall on November 13th, the S&P 500 index had 19 consecutive Monday highs, including even the uneasy times when the Israeli-Palestinian conflict broke out.
