Buffett's 1988 Letter to Shareholders:

Berkshire Hathaway Book Value Per Share: $2,974.52

Quotes:

"Even honest and well-intentioned managements sometimes stretch GAAP a bit in order to present figures they think will more appropriately describe their performance. Both the smoothing of earnings and the “big bath” quarter are “white lie” techniques employed by otherwise upright managements."

"Moreover, our experience with newly-minted MBAs has not been that great. Their academic records always look terrific and the candidates always know just what to say; but too often they are short on personal commitment to the company and general business savvy. It’s difficult to teach a new dog old tricks."

"We are just the opposite of those who hurry to sell and book profits when companies perform well but who tenaciously hang on to businesses that disappoint. Peter Lynch aptly likens such behavior to cutting the flowers and watering the weeds."

"To evaluate arbitrage situations you must answer four questions: (1) How likely is it that the promised event will indeed occur? (2) How long will your money be tied up? (3) What chance is there that something still better will transpire - a competing takeover bid, for example? and (4) What will happen if the event does not take place because of anti-trust action, financing glitches, etc.?"

"Berkshire’s arbitrage activities differ from those of many arbitrageurs. First, we participate in only a few, and usually very large, transactions each year. Most practitioners buy into a great many deals perhaps 50 or more per year. With that many irons in the fire, they must spend most of their time monitoring both the progress of deals and the market movements of the related stocks. This is not how Charlie nor I wish to spend our lives. (What’s the sense in getting rich just to stare at a ticker tape all day?) The other way we differ from some arbitrage operations is that we participate only in transactions that have been publicly announced. We do not trade on rumors or try to guess takeover candidates. We just read the newspapers, think about a few of the big propositions, and go by our own sense of probabilities."

"The preceding discussion about arbitrage makes a small discussion of “efficient market theory” (EMT) also seem relevant. This doctrine became highly fashionable - indeed, almost holy scripture in academic circles during the 1970s. Essentially, it said that analyzing stocks was useless because all public information about them was appropriately reflected in their prices. In other words, the market always knew everything. As a corollary, the professors who taught EMT said that someone throwing darts at the stock tables could select a stock portfolio having prospects just as good as one selected by the brightest, most hard-working security analyst. Amazingly, EMT was embraced not only by academics, but by many investment professionals and corporate managers as well. Observing correctly that the market was frequently efficient, they went on to conclude incorrectly that it was always efficient. The difference between these propositions is night and day."

"Naturally the disservice done students and gullible investment professionals who have swallowed EMT has been an extraordinary service to us and other followers of Graham. In any sort of a contest - financial, mental, or physical - it’s an enormous advantage to have opponents who have been taught that it’s useless to even try. From a selfish point of view, Grahamites should probably endow chairs to ensure the perpetual teaching of EMT."
