| Mar 16, 2014 at 22:29 | comment | added | meh | I don't understand what the paper has to do with finance. I scanned it and I can say that I didn't see anything interesting from a finance point of view. It offers nothing on how this arrangement could be used. I think he could just as easily take temperature readings from different cities for his data points. There may be somebody drinking rum in the tropics based on this idea. However, I have never heard of anyone caring about that particular data point. Some of the authors introductory remarks suggest to me that he is not that familiar with stock trading. | |

| Mar 16, 2014 at 3:08 | comment | added | Douglas Zare | I don't think that the changes in ordering of the prices in a stock market capture the most important changes. Note that unless there are fixed points (which get decorated with whether the price increases or decreases), every stock price could have gone up, or all could have fallen. Wouldn't this be important? This information isn't present in the permutation. In addition, economists normally say that the nominal prices aren't important, that a split shouldn't change anything, but it would change the permutation. This paper doesn't seem connected to understanding the stock market. | |
