On Friday US markets ended up in a session that was again marked by high volatility, thus completing the worst week for stock markets since January 2016. During the session, the S&P ranged from a loss of 1.80% to a appreciation of 2.10%. The magnitude of the S&P oscillation becomes sharper when compared to the fact that in 2017, the American index recorded about 150 consecutive sessions with oscillations of less than 1%. The day was totally dominated by market factors, which replicated the movements of the previous sessions. During the day, there were some selling associated with automatic programs and the foreclosure of positions held by investors who had resorted to financing to buy stocks. Also during the day, there was a buyer interest, a bit hesitant, but that prevailed in the last half hour of the session. The recovery at the end of the day is positive, but it is still not enough to assert, always with a dose of uncertainty, that marked the end of the recovery. It was not yet possible to identify who were the buyers who conducted the indexes to positive territory in the last part of the day. There is an aphorism on Wall Street that indicates that markets never touch the lows on Fridays. However, from a technical point of view, for a recovery to gain a more solid and lasting dimension, it would be important for the S&P to close, with a strong volume, above 2638 (which corresponds to Friday’s high).
