Looking for top performers is always invoking survivor bias. It's a classic data snooping issue where the common sense approach is exactly wrong, but it'll sell a lot of books and it'll convince people who you know what you're doing as a stock analyst when it's just random luck.

Top 10 performers out of 16 or so analysts in the analysis is not survivor bias.
Sure it is, it was survivor bias when you selected the 16.
