How to Become a Better Analyst – One Hour at a Time
Geoff here.
Over at Portfolio14, there is a good question about spending time researching new stocks as opposed to just adding to the same old positions:
Charlie Munger always says diversification is diworsification. My dilemma here is whether I should diversify in order to reduce my exposure to one single company. No matter how high my conviction is, there are always “unknown unknowns”. There is also this unhelpful thought urging me to divest: “Earning outstanding returns requires hardwork. If I keep on adding to just the same old position and not spending time to dig deep into other companies, I’m not working hard enough.”
This is a great question to ponder. On the one hand, I agree that diversification often leads to diworsification. On the other hand, it is important to practice, practice, practice:
A little over a year ago, Geoff Gannon wrote a post where he gave readers the salient financial information of company, but didn’t give the ticker/name of the company. He then had readers guess the stock price. It was an amazing little experiment derived from a quote of Warren Buffett where WEB goes on to say he likes to guess the stock price before looking at the actual price when he analyzes investments.
As always, WEB was well ahead of his time. Much work and study from behavioral finance/economics, like that of Daniel Kahneman, discusses the effects anchoring has on each of us. If we see a stock price before valuing the company, we will unconsciously fix our valuation near the actual price.
Ever since Geoff’s original post I have been fascinated by the experiment. I even went as far as making an Excel program that would randomly generate ticker from the Russell 3000, display the financial information with ticker and price hidden. I could then go about valuing the company and check my work to see how I was doing.
What’s the solution here?
Be Focused in Your Buying – But Omnivorous in Your Research
Should you buy a lot of different stocks? Analyze a lot of different stocks but don’t buy them? Or take the Peter Lynch approach and buy tiny amounts of many stocks just to keep them on your radar – then only load up on the ones you really love?
It’s a tricky question. To gain experience you need to do something similar over and over again. But it can’t be exactly the same. Otherwise, you will become experienced just at that one task. If you become an expert at analyzing Microsoft (MSFT) – you will know how to analyze Microsoft, not how to analyze stocks generally.
Use Real World Examples to Master Abstract Concepts
There’s another complicated issue that has to do with patterns.
I think two of the surest signs of real mastery of a subject are:
- Ability to talk fluently about the subject in everyday language without use of jargon; ability to use short sentences; having
