Mohnish didn't publish his, saying that it would be more beneficial for one to develop his or her own. I would agree with this, because each investing style and process is somewhat unique. Moreover, the process of building the list is beneficial because it gets you thinking about what you value when you buy a stock.
Nevertheless, I thought I'd share mine. This is really nothing special. And it's not nearly as detailed as Mohnish's 88-question checklist. It's just meant to basically reaffirm my thesis and help me make sure I've covered the basics. Another difference I have with Pabrai is that my checklist is used after I've spent some time looking at the investment opportunity, but not before doing a lot of detailed research. I think he mentions that he runs his checklist right before making a "buy or not buy" decision.
So without further comments, here is the screenshot of my checklist. I'd love to hear any thoughts or recommendations, or if you have your own checklist, feel free to share/comment:
The basic idea behind my checklist is to focus on the three basic categories of risk: Valuation risk, Leverage risk, and Business risk. All risk can be traced to one of these three areas, and using a checklist can help you mitigate these risks.
Last Two Questions Are Key
The final two questions really help me stay focused on prioritizing investment opportunities. I think about the risk and the downside first, but once that is handled, in order to make money you still need upside. Asking the simple question: "Will this stock double?" has had a surprisingly helpful effect. It also allows me to toss aside mediocre opportunities so I can focus more on the best risk-reward scenarios. By the way, this question was also something I learned from Pabrai.
The last question is another very basic one, but again, it's quite helpful: "Would I buy more?" It forces me to think about the fact that I'm buying a business and not just speculating on an increase in stock price. If the answer to this question is: "no" (assuming the thesis hasn't changed), then you may want to pass on the investment.
There is no science to any of this. The idea is to simply implement something to get you thinking about everything that is important to you when you make an investment. I just started using a formal checklist, and I'll probably add to this over time, including more qualitative questions, but for now, this seems to be helpful in organizing my thoughts and prioritizing opportunities.
