Thanks to MoneyWeek magazine for picking these.
Pound Cost Average your whole life and you’ll beat anyone who doesn’t
Only invest in things you can explain to a six year old
Every five to seven years people forget recessions happen every five to seven years
You’re twice as biased as you think you are (four times if you disagree with this statement)
Read more books and fewer articles
Read more history and fewer forecasts
Why visit your doctor once a year and check your investments once a day?
Be careful when reading how stupid investors can be and not thinking about yourself
Your circle of competence is smaller than you think it is
You’re only diversified when some of your investments perform a lot worse than others
Keep reading MoneyWeek! (I added this in as they’d only flagged nine!)
