Jason Zweig’s Rules for Investing

Coming up this week for our Masters in Business podcast, I am sitting down for a conversation with Jason Zweig.

One of my favorite books of his is Your Money & Your Brain. Buried within its appendix is a great list of common sense rules that are commonly ignored. Perhaps I can find a few questions here to go over this with him.

 

Jason Zweig’s Rules for Investing

1. Take the Global View: Use a spreadsheet to track your total net worth — not day-to-day price fluctuations.

2. Hope for the best, but expect the worst: Brace for disaster via diversification and learning market history. Expect good investments to do poorly from time to time. Don’t allow temporary under-performance or disaster to cause you to panic.

3. Investigate, then invest: Study companies’ financial statement, mutual funds’ prospectus, and advisors’ background. Do your homework!

4. Never say always: Never put more than 10% of your net worth into any one investment.

5. Know what you don’t know: Don’t believe you know everything. Look across different time periods; ask what might make an investment go down.

6. The past is not prologue: Investors buy low sell high! They don’t buy something merely because it is trending higher.

7. Weigh what they say: Ask any forecaster for their complete track record of predictions. Before deploying a strategy, gather objective evidence of its performance.

8. If it sounds too good to be true, it probably is: High Return + Low Risk + Short Time = Fraud.

9. Costs are killers: Trading costs can equal 1%; Mutual fund fees are another 1-2%; If middlemen take 3-5% of your cash, its a huge drag on returns.

10. Eggs go splat: Never put all your eggs in one basket; diversify across U.S., Foreign stocks, bonds and cash. Never fill your 401(k) with employee company stock.

 

Great stuff!
