Models for investing in the stock market...
abc3: I think the question is a good one, and I think it's clear you did a fair amount of research before writing your post. There are several other philosophies you could have included but didn't, and the three you chose are the only ones that I believe make sense.I suggest a broader approach to "The Warren Buffet Berkshire Hathaway model." Buffett is a value investor, and frequently cites other value investors who have started with similar assumptions (based on Benjamin Graham's work) but who don't necessarily place few bets (Buffett credits Philip Fisher, and also Munger, with making him a believer in concentrated portfolios).The value investors I recommend reading, in addition to Buffett, Graham, Fisher, and Munger, are Martin Whitman, Seth Klarman, and Christopher Browne. Browne's letters and studies are available for free on the Tweedy, Browne website, Klarman's book (Margin of Safety) can be found as a pirated PDF, and Whitman's books are relatively inexpensive (and his letters to shareholders are free). Also, in addition to reading shareholder letters by Buffett and Munger, be sure to check out Lowenstein's Buffett biography (and The Snowball, though it's not nearly as good; Janet Lowe's Munger bio is a waste of paper).
