 Some 53 years ago I worked on the crisp files [CRSP ] and formulated a hypothesis. Stocks breaking through the round #s 10 and 100 tended to outperform the market. I didn't trust my results at the time as I was just learning to program and my stump tailed macaque distracted me from work on the 7094 [IBM 7094 ] which had a 24 hour turn around if you made the slighted typographic mistake on your program. The results while very alluring were overwhelmed by the fact that many of the companies reaching the criteria did so in battalions in years like 1933 or 59 or some such. I wasn't agile enough at the time to perform a Mann Whitney test of the performance of these companies versus randomly selected counterparts at the same time. However, the study would be worthwhile to do, if one had an exact as is, with no retrospective file. Perhaps someone will do it correctly and see how it did relative to my hypothesis and the related hypothesis of the J. Livermore who departed from life at the Sherry Netherlands because of excessive vig.
