Why Did the Market Drop So Fast? Making Rational Sense of an Irrational Market

As the late George HW Bush once said, “What is it about August?”

The markets are off to a rocky start to begin the month. After finishing the month of July with a +1.57% day, the S&P 500 fell -1.37% on Thursday and -1.8% on Friday, before opening down -4% on Monday. This is certainly not the start investors would have hoped.

Reasons for the Decline

There have been a few different proposed “reasons” behind the decline in the first few days of August. Perhaps it is nerves from the upcoming election. We will know the US Presidential candidates and their running mates in the coming few days. This selloff could be a reaction to both the polls and speculative policies. Some may also attribute the selloff to the Federal Reserve being too slow to lower rates. Last week’s economic data showed that payrolls increased lower than expected, and the unemployment rate hit a 3-year high.

The selloff to open Monday’s trading has been widely credited to global concerns. As a reaction to poor job reports in the US, the Nikkei index (Japan) tumbled over the weekend, declining by -12%. Part of this decline could be due to an unwinding “carry trade.” One popular investment strategy in the last few years has been borrowing foreign currency, such as the yen, for cheap and investing elsewhere at a presumably higher yield. In the last week, however, the yen has surged in value relative to the US dollar, causing investors to devest from Japanese assets and signal a “risk off” environment.
