I was retrieving some quotes from Yahoo finance today, and I received some very strange values. Consider the following query:
which retrieves the quotes for the Jarden corporation, starting at 2013/03/01, up to 2013/04/01. Now at the dates 2013/03/18 and 2013/03/19, there is a sudden price drop of about 20 dollars. This price drop is not visible on the Yahoo finance website (http://finance.yahoo.com/echarts?s=JAH+Interactive#symbol=JAH;range=1y), or any other financial source for that matter.
Therefore, I think the quote data has to be wrong. Another fun fact if you were to take the price retrieved from the API at 2013-03-18 (the last incorrect price), multiply it with 2/3, you arrive at the price displayed on the website (64.24 * 0.6666666667 = 42.16).
Does anyone have even the slightest idea of what is going on here?
