A simple investment principle
Knowing nothing is better than acting on a false indicator
Details are a swamp. Stay away.
Every decision is two part. Do this and as a result, don’t do that.
Be sure investing behaviour matches how the score is actually measured.
Don’t build monoculture portfolios
Understand context before you make crucial decisions
Uncertainty is the constant
Beware of easy answers
The short run must work or else
