1. Look past the stock to the underlying business.
2. View market fluctuations as opportunity to profit from the folly of others.
3. Invest with a margin of safety.
I think those three ideas, 100 years from now, will still be regarded as the cornerstones of sound investing. (Warren Buffett)
Buffett has used those principles that Ben Graham laid out six decades ago to great effect (turning about $100K into $50 billion), but he has no monopoly on them nor are they patented.
Hint hint. Wink wink. Nudge nudge.
What we're saying is that if everything you do as an investor is consistent with Graham's three cornerstone principles, you'll do more than fine. For fun, we try scrutinizing the investment advice you receive and see how they are so often ignored or violated outright.
