@expatsp: good question ... especially since I am in the middle of a portfolio re-organization (for myself and my wife) to better reflect how likely we are to rebalance and etc. !
Some background...
In general, before I buy
into a fund, I do a lot of research. I consider my asset allocation, role in portfolio, etc. I don't look at simple average returns without also considering downside / upside capture and cumulative returns. I used to go so far as to do a correlation and simulation exercise to determine if the candidate fund would add bang to buck while acting differently than my core 4-
5 funds. I like managers who know how to hold cash.
Before moving
out of a fund, I try to be very sensitive to my own biases and put the breaks on any temptation to jump in and out of funds. I want stuff I can buy and hold; I don't want to fall into the trap of "OMG I should be doing something all the time" and thus getting low investor returns because I can't leave well enough alone. I remain sensitive to the fact that solid active managers will underperform. I have held funds that have underperformed over 3 year intervals for example, and have gone on to deliver long-term above-average results. So, I want something more than just a bad stretch to make a move. I don't mind a concentrated portfolio, and philosophically am skeptical of crowd phenomena.
FAIRX fulfilled all of my buy criteria when I first became a shareholder in 2007. I resisted the temptation to go all-in during its heyday, and kept it at
5% of my portfolio, in a sleeve that I consider alternate approaches. I have not rotated into or out of the fund, and have made money on it since I bought in. Oddly enough, however, in holding FAIRX I would have done no better since 2007 than if I had bought and held a decent bond fund...
So, all that said...
I guess I have held on to FAIRX in large part because of the biases and philosophy noted above, and its small share of my total portfolio. But also I made a career change in 2011, and have increasingly had much, much less time for investing (because I have less time for anything). I was also insufficiently sensitive to the issues that LewisBraham notes above. I always had more of an emotional attachment to the FAIRX philosophy, then to Bruce himself. That said, I was ticked off by Bruce's AUM and publicity spree, as well as what might be considered flaws in personal judgement (Barron's piece), but just never got around to making a move, because I bought into his theses. Now, silly as it seems, the issue is identifying the suitable fund to rotate into given my current portfolio.
