Blast from the past, here is an excellent post by Marcus Brutus on CYOE and Yahoo's ratings
============================

Yahoo! uses Zack's "average" or consensus recommendation for the rankings. Therefore, since the average recommendation for CYOE is a strong buy (or 1), then CYOE is ranked with the (as of this moment)11 companies within the Telecom equipment sector with that average ranking.

Rather than listing 11 companies at the same "rank", Zack's further segments the rankings by the number of analysts who contributed to the ranking. So, the company which is ranked #1 (INTL) above the two companies which are tied at a ranking of #2 (ACSC, TTN) is considered higher because 6 analysts issued an average of 1 (i.e., all call it a strong buy) versus 4 each tracking the latter two companies. The five remaining companies with an "average" recommendation of "1" have only 1 analyst tracking each of them. Therefore these five companies share the #4 ranking slot.

The next ranking group starts with an average of 1.2 and is given the #9 ranking.

This is the process used to calculate intra-sector rankings and why CYOE, with a single analyst (who is with a market maker in CYOE) issuing a strong buy recommendation 2 quarters ago, is in the top 10 on this list. IMHO, unless a consensus recommendation has several analysts (after eliminating the market makers because their recommendations are suspect), these rankings are pseudo-science and meaningless. I know, I know, given my history of support for CYOE it's hard to figure out why I think that. My views regarding CYOE aside, as a statistician, this ranking approach is seriously flawed when evaluated for making investment decisions.
