The Dangers of Holding on to Great Stocks
Someone emailed me a question about Activision (ATVI), a stock I put 100% of my portfolio into a little over 16 years ago (the stock went on to return 22% a year – but, of course, I didn’t hold on to it these last 16 years):
“Would it be fair to say that your returns would have been much better had you just put all your money into Activision at the time you initially bought it… and just sat on your butt until now? Let’s assume that this is a fair assessment for now.
So if we brought ourselves back to the year you bought it, early 2000s was it? If we looked at it with the models you currently possess but likely did not possess back then, could you have made a better allocation based on those models alone?”
The only “model” I can think of that would have improved my performance is not letting myself make any conscious sell decisions. In other words, just selling pieces of all the stocks I own in proportionately equal amounts to fund new purchases, never selling just to hold cash, etc.
I wrote an article discussing some of this. Overall, my sell decisions haven’t added much (if any) value to my investing record. My investment results are primarily a result of taking larger than normal positions in some stocks and then secondarily in picking the right stocks more often than I pick the wrong stocks.
With hindsight, I would have done as good or better while doing far less work if I’d just stuck with a stock like Activision that I once (16 years ago) had the conviction to put 100% of my net worth into it.
However, I think there is both: 1) A valuable truth and 2) A dangerous falsehood in this kind of thinking. Basically, what you’ve uncovered here is a good idea. But, a good idea can be taken to a bad extreme. And, I think the combination of 1) abusing hindsight and 2) going off the stock performance rather than the business performance can skew just how good and certain an idea Activision really was in September of 2001 (when I allocated 100% of my portfolio to it).
I couldn’t have foreseen that Activision would return something like 20% to 25% a year for the next 15-20 years. At the time, I thought I was able to foresee Activision could return 10% to 15% a year for the next 10-15 years though. Now, it’s true I thought this thought with enough “certainty” that I was willing to put 100% of my portfolio into the stock. But, I didn’t go “all in” on Activision believing I could make 20% to 25% a year. I did it believing I could make 10% to 15% a year (with greater confidence than I had in any other stocks).
Since 2001, Activision’s capital allocation has turned out to very good, or very lucky – or some combination of the two. Should …
