The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage. The products or services that have wide, sustainable moats around them are the ones that deliver rewards to investors. –Warren Buffett (1999)

The most important thing to me is figuring out how big a moat there is around the business. What I love, of course, is a big castle and a big moat with piranhas and crocodiles.” Warren E. Buffett (1994)

  2. Hi, John.

    I am a fan of you blog. Congratulations on your work. Is is a great resource for new investors.

    My question is: do you have any recommendation on sizing of holdings? It is not a topic much covered in the investment world. In general the focus is on what to buy/sell, but not how much of it.

    Thank you in advance
