What a month August has been so far, with the S&P 500 Index up more than 7%, for the best August since 1984. Not to be outdone, this is the first time in history August saw two separate 6-day (or more) win streaks. Last, with one day to go, the S&P 500 has gained 16 days so far this month, for the most since 16 in April 2019. Meanwhile, it is the most up days for any August since 2003.
