This is the largest one-day drop in history, and it is known as the flash crash. In 6 minutes Dow lost 600 points then recovered. The difference between high and low on May 6 was about 1,000 points, and Dow went below 10,000. Is it a technical glitch, foul play or natural cause?
To investigate this massive collapse, you are asked to:
- download publicly available daily stock prices (volume, open, low, high, close) for all stocks that are listed on the NYSE or Nasdaq (you can get the data from Yahoo Finance and download it using a web robot
-- there is about a few thousand stocks)
- is the collapse evenly spread among all stocks? Any abnormality? What would the worse drop (for an individual stock) be if the average is 10%, given the number of stocks in NYSE or Nasdaq?
