if ur intention is invest aka hold lama-lama (15/30/45yrs), my experience told me data (peg, nta, fcf & etc) is a very first defense, dy is second as ur cash flow for spending or derivatives, company prospects would be the key for my decision.

for speculative play; peg, mkt theme & vol would be my priority

tat is 4 my speculative play, 4 long term investment, i never bother on the vol
