Интересная статья, еще от 16.03 в которой один дядька предсказал повышенную волатильность последних дней:

Apple Enters The Dow Just When Good News May Be Priced Into The Stock's Recent High

price action over the next week could confirm a stock market correction given the FOMC Statement and Fed Chief Janet Yellen’s press conference on March 18 and Quadruple Witching on March 20.

Market weakness last Friday can be attributed to the possibility that the FOMC Statement released on March 18 will not include the word “patient” and thus investors will assume that the federal funds rate will likely be raised following the June FOMC meeting.

ТА стоков (просто интересно), который использует дядька:

A daily chart contains 50-day and 200-day simple moving averages. A weekly chart contains a five-week modified moving average, a 200-week simple moving average, and a 12x3x3 Weekly Slow Stochastic, which is a measure of momentum. Stochastic readings range from 00.00 to 100.00 where a reading below 20.00 is oversold and a reading above 80.00 is overbought.

A market or specific stock has a positive weekly chart given a weekly close above its five-week modified moving average with momentum rising above 20.00. A market or specific stock has a negative weekly chart given a weekly close below its five-week modified moving average with momentum declining below 80.00. Any other combination is neutral.
