Friday will likely be the year's biggest stock market volume day with big action in Apple, JP Morgan
FTSE Russell is rebalancing the large-cap Russell 1000 and the small-cap Russell 2000 indexes, which happens only once a year. Last year's reconstitution on June 23 saw nearly 5 billion shares change hands, the second busiest day of 2017. A little-known indexing event on Friday will likely result in the year's biggest volume day, with large trading and potential price swings in well-known names like Apple, Microsoft, J.P. Morgan, and Grubhub.
