On The Two That Got Away
“The investment shown by the discounted-flows-of-cash calculation to be the cheapest is the one that the investor should purchase – irrespective of whether the business grows or doesn’t, displays volatility or smoothness in its earnings, or carries a high price or low in relation to its current earnings and book value.”
(Read Warren Buffet’s 1992 Annual Letter to Shareholders)
Lately, I’ve been thinking a lot about Fisher and Munger and their influence on Buffett. If I have not said it before, let me say it now: I believe both men’s influence on Buffett’s investment decisions have been overstated. I do not mean that as a slight to either man. They both have impressive records of their own, and they both offer a lot for investors to study. Phil Fisher and Charlie Munger are two of the greatest investment thinkers of all time. Besides, this post is not about the influence these men had on Buffett. This post is about investment mistakes I have made – mistakes I would not have made had I heeded the advice of Fisher, Munger, or Buffett.
This post is, at least in part, the result of the time I spent at Jason Bond’s blog over the weekend. That may not be obvious; nevertheless, it is true. I’m currently working on a three part podcast series on spotting great companies. I’m also in the process of reviewing two books: Phil Fisher’s “Common Stocks and Uncommon Profits and Other Writings” and Charlie Munger’s “Poor Charlie’s Almanack”. Obviously, these projects are closely related. That fact has been reinforced by two activities I engaged in this week: rereading Warren Buffet’s annual letters and visiting Jason Bond’s blog. Having done these things, I knew I had to write this particular post today.
Two weeks ago, I posted “On Blogs as Public Records”. In that post, I wrote:
“We’ll go over my mistake. Think of it as an autopsy. We’ll determine the cause of my error, and look to prevent it from creeping into our thinking in the future.”
Not surprisingly, both of the biggest mistakes of my investing career have been errors of inaction. However, these errors were not passive. When analyzing decision making, inaction must always be considered an action. A choice is made in either case; whether the outside world sees the results of that choice or not is irrelevant to an analysis of one’s own judgment – or misjudgment.
Three years ago, I failed to buy shares of Building Materials Holding Company (BLG). A year ago, I failed to buy shares of PetMed Express (PETS).
In each case, the stock was clearly undervalued. In each case, I did an intrinsic value analysis and compared the margin of safety to all possible alternatives. In neither case, did I find a possible alternative that had a margin of safety even remotely comparable to that of the stock being considered.
I will spare you the details of my analyses. It is …
