GM,

No, I do not know of one site that has all the info in one place.

People using P&F are a small, but elite, group in the investor/analyst spectrum. It always gives me a chuckle when I think that Chartcraft doesn't have a website or an email address.

RE: 100 minimum stocks in a group

From what I've read of Tom's writings, I have not seen a specifically defined reason for the number 100.

Statistics theory, the central limit theorem specifically, says that a population only has to be greater than ~30 members to allow that population to be treated as having a normal distribution and all that that implies. From observing some of the key percentage points that Tom uses, it appears that these coincide with some of the key percentage points of the normal distribution.

But, I will ask Jan to ask Tom to reference or clarify the reasoning behind the 100 stock population requirement. O.K., Jan?
