How to know if a stock is fundamentally strong?

How can I determine if a stock is fundamentally strong? Is there a specific formula or set of criteria to follow? What financial indicators should I be looking at? How important is it to consider the company's earnings, revenue growth, and profit margins? Are there any other factors, such as industry trends or management team, that should also be taken into account? Can you provide some practical tips or strategies for conducting fundamental analysis on a stock?
