Competition: What caused May 6 stock market collapse?
AnalyticBridge competition: investigate the spectacular stock market collapse of May 6, 2010
From: Vincent Granville
Date: May 16, 2010
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
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?
