Why Due Diligence Matters

Stock Research Made Simple

Step 1: What Do They Actually Do?

  • Can you explain their business to a 10-year-old?
  • How do they make money?
  • Would you shop there or use their product?

Step 2: Are They Making Money?

  • Do they turn a profit every year?
  • Are profits going up or down?
  • Are they drowning in debt?
  • Do they have cash in the bank?

Step 3: Is the Price Crazy?

  • Are you paying too much for each dollar of profit?
  • How does it compare to similar companies?
  • Has the price doubled recently? (Warning sign)

Step 4: What About the Competition?

  • Is this industry growing or dying?
  • Who are the main rivals?
  • Is technology about to kill this business?

Fund Research Even Simpler

Step 1: What’s the Game Plan?

  • What do they buy?
  • What are they trying to do?
  • Does it match what you want?

Step 2: How Have They Done?

  • Good performance over 5+ years?
  • Better or worse than similar funds?
  • Did they crash harder in bad times?

Step 3: What’s It Cost?
