Warren Buffett’s Partnership Letters and My Investing Thought Process
“You can’t predict. You can Prepare.”
-Howard Marks
I have been reading all of Warren Buffett’s old partnership letters the past week or so. These letters are the letters he wrote to his Investors yearly (and then semi-annually) from 1957- 1970 before winding down his partnerships to eventually run Berkshire. I was inspired to do so because I have also been rereading The Snowball by Alice Schroeder’s for the past month, and it’s awesome how it takes you back to the beginning and goes year by year in Warren’s life as the snowball was building up and starting to roll downhill. There are a few books I re-read every year, and The Snowball is one of them. (Also on that list is Poor Charlies Almanack, another book I highly recommend.) The partnership letters are too long to embed in this post, but if you go to this link you should be able to pull them yourself:
Although Warren invests completely differently now, there are still a lot of takeaways you can pull for yourself from his writings. One thing I found interesting is on page 20 in his 1961 letter where Warren goes over his different types of Investment Categories. I’ll let him explain:
“The first section consists of generally undervalued securities (hereinafter called “generals”) where we have nothing to say about corporate policies and no timetable as to when the undervaluation may correct itself. Over the years, this has been our largest category of investment, and more money has been made here than in either of the other categories. We usually have fairly large positions (5% to 10% of our total assets) in each of five or six generals, with smaller positions in another ten or fifteen. Sometimes these work out very fast; many times they take years. It is difficult at the time of purchase to know any specific reason why they should appreciate in price. However, because of this lack of glamour or anything pending which might create immediate favorable market action, they are available at very cheap prices. A lot of value can be obtained for the price paid. This substantial excess of value creates a comfortable margin of safety in each transaction. This individual margin of safety, coupled with a diversity of commitments creates a most attractive package of safety and appreciation potential. Over the years our timing of purchases has been considerably better than our timing of sales. We do not go into these generals with the idea of getting the last nickel, but are usually quite content selling out at some intermediate level between our purchase price and what we regard as fair value to a private owner. The generals tend to behave market-wise very much in sympathy with the Dow. Just because something is cheap does not mean it is not going to go down. During abrupt downward movements in the market, this segment may very well go down percentage-wise just as much as the Dow. Over a period of …
