I first heard about Jason Zweig on his preface of one of Ben Graham's books and that got me curious. This is a short summary of the value investing principles and behavioral biases when it comes to personal and private investment decisions. Seasoned value guys will already know but these things are always good to remember.
My main random take aways are as follows : Investing is simple but not easy. Don't take risk that is not necesary. Don't take risk that is unlikely to be rewarded. Don't invest money you cannot loose (dont leverage). Think twice. Always have one year of living expense at the bank. Be aware of the risks to your income streams, curreny, job sector, skill obsolesence. Don't invest where you work. Build up your human capital. That reminded me that WB keeps repeating: invest in yourself. I have always been a big believer in continous education myself and couldn't agree more. I wished he had stressed how even more so this has become in an era of accute specialisation and rapid change which can leave many people on the sideline. I believe the risk today is that the gap with those who don't get that will grow ever bigger. Focus on risk vs reward. Invest to own businesses. Preserve a margin of safety in case things don't turn out as expected. Favor passive indexing as same thing as owning the whole economy of your country. No risk of missing out or failing to cherry pick. Save as much as possible. Be careful of people who want to sell something to you. Engaging names for products and fancy tickers for fancy stocks are marketing tactics. Always be cautious.
Women are better investor. Why? less bragging, less competitive, more cautious, more sensible, trade less frequently, expect lower return, realistic, more concerned, wait before taking action. Bottom line ask your wife to review your investing ideas and in general your life decisions I would even add. My wife says I don't do enough of that, but I think she exaggerates lol.
Be careful of the behaviroal biases: framing, cognitive ease, priming, halo effect. Remember the importance of score cards. Sleep over decisions before taking them. Dont listen to promises of quick wealth. Be scpetical. Don't fall in fools traps.
He also talks about a book "how to lie with statistics" which I saw in Bill Gates' reading list. I think I'll add it to the priority list.
