Also, I'd respectfully suggest that if you have to ask this kind of question, your chances of beating the market based on stock valuation insight are rather slim.
This felt unnecessarily rude. The OP didn't even say he was looking to buy the stock or make any investing decision (and actually literally said that he doesn't plan to buy individual stocks), but rather that he was just trying to learn more about how companies are valued.
You're probably right. A willingness to learn should be supported, not shot down, but I worry that a little knowledge can be a dangerous thing, especially when it comes to investing in individual stocks. Doing cursory "analysis" by looking at things like P/E ratios can give an investor the false belief that a stock is a "good value" when in fact more savvy investors have priced a stock "cheaply" because it is, in fact, high risk.
I'll modify my original statement by saying, doing good fundamental analysis is extremely hard. Like any skill, it takes years of hard work to do it well, and a demonstrated mastery (even without the ability to consistently pick winners) will land you a mid-six to seven figure salary on Wall St. If you're up for a lot of work and study, then have at it, especially if you hope to parlay your knowledge to a career into finance.
Ultimately, I feel like this kind of question is akin to "how do I diagnose my wife's illness?". You can offer some pointers about using WebMD, but the right answer is that you need to go to medical school.
