DD
Due diligence
When you're discussing stocks or other investments, DD stands for "due diligence." Financial advisors, finance forum posters, and investment-related websites often tell investors to perform their own DD before buying in to any company.
What, exactly, DD involves is up for debate (see the Reddit example pictured below). However, doing your due diligence on a company and its stock typically includes:
- Investigating the company's balance sheet, cash flow, and management
- Comparing the company with its competitors
- Assessing the company's strengths and weaknesses
- Considering industry and worldwide trends that may affect the company
- Examining the company's short- and long-term growth
Only after you've completed all these tasks (and potentially, a few others) have you performed your due diligence.
