Review SEC filings for detailed analysis of operations and financial performance. The best SEC filings to review are the 10K, 10Q and recent 8Ks.
The 10K is the annual filing that has several sections worth looking at including the Business Description (outlines the company's strategy including strengths and opportunities), the Risk Factors (describes things that might prevent that strategy from being executed including threats and weaknesses) and the Management's Discussion and Analysis of Financial Performance and Operating Conditions (does just what it says!)
