We wrote in the January Green Book that the S&P 500 Christmas Eve low did not have the “right look,” in that: (1) there had been no sign of “smart money” accumulation beforehand; and, (2) downside momentum was also at a new low for the entire correction. Smart money buying is measured by the Smart Money Flow Index, which evaluates trends in first half-hour market action (considered to be more emotional and news-driven), and the last hour of trading (viewed to be more informed and institutional in nature).
