I have a question regarding the following part of the FAQ:
"Can I invest based solely on GrahamValue's screeners?
Filtering by automated statistical or quantitative analysis is only the first step of the investment research process.
When multiple complex and autonomous informational systems are interfacing with one another — for providing data, extracting analyses, processing payments and so on — there is always some room for the occasional technical error to creep in.
This is why it's imperative that one always do one's personal due diligence — and verify shortlisted stocks oneself — before making a final investment decision."
Does this mean that the most safe way is to perform the calculations myself as well, or it means that you recommend additional analysis?
Thank you in advance!
