KEY TAKEAWAYS
Due diligence is a systematic way to analyze and mitigate risk from a business or investment decision.
An individual investor can conduct due diligence on any stock using readily available public information.
The same due diligence strategy will work on many other types of investments.
Due diligence involves examining a company's numbers, comparing the numbers over time, and benchmarking them against competitors.
Due diligence is applied in many other contexts, for example, conducting a background check on a potential employee or reading product reviews.
