Equities ended the week higher: SPY and DJIA rose 1% and NDX rose over 3%. Outside the US, Europe gained 1% and EEM gained 3%. The biggest mover was oil, which gained 12%.
The last two weeks have been remarkable. On August 17, SPY closed less than 1% from its all-time closing high. A week later it had lost 11%. And then three days later it had regained half of those loses, jumping 6%.
A drop that much, that quickly, is very rare. According to David Bianco, it has happened only 9 times in the more than 20,000 trading days in the past 80 years. All of these occurrences were precipitated by (perceived or real) political or economic crises.
