As far as stops --- amateurs & beginners tend to think that this is a successful technique. It isn't.
Based on a lot of testing, I agree.
Unhappily, I learned it in one lesson.

There are lost of different investing strategies in the universe.
Whether you're Warren Buffett or somebody listening to (ugh) Cramer, there is a trigger for a purchase and a trigger for a sale.
The trigger might be simple or complex, and may or may not involve a stop loss.
Each entire combination of rules has to be considered as a set when discussing whether something "works" or not.

As far as I know adding stop losses does not improve results on any quant screening
approaches similar to those discussed here, based on a lot of research.
Stops may add value when you're using hand selected stocks by some
"expert" on the internet, or in other situations, I don't know.
Different questions, different answers.

Based on the evidence, for what we do here, if you use stops you'll do worse.
If you don't believe the output of testing, don't use this family of approaches at all.
