I look at the PE as a final deciding factor. The start is always EBITDA, EPS. However, you may need to program some form of weighted score on the firm's management, likely a likert scale.. This cannot be overlooked as most stock prices are a factor of information hence a captain that disseminates it well shall aid the share price up. All the best!
