Buffett: Stocks Can Sell at Silly Prices

The Efficient Market Hypothesis (EMH) has long been a cornerstone theory in understanding stock market behaviour. It posits that at any given moment, stock prices accurately reflect all available information about a company. This theory gained significant traction during the 1970s, buoyed by the rapid expansion of the Information Age, which revolutionized data storage and exchange.

In an era where even casual investors wield valuation tools that would have seemed like science fiction to traders of the past, one might assume that market efficiency has reached unprecedented levels. However, Warren Buffett challenges this notion, noting that the market is mostly efficient but not completely efficient.

Buffett contends that in some cases the market is far from efficient. Contrary to the belief that stock prices consistently reflect a company’s true value, Buffett argues that market inefficiencies are inherent. He asserts that stocks often become mispriced due to various factors.

Speaking at the 2012 Berkshire Hathaway Annual Meeting, Buffett referenced Benjamin Graham’s seminal work, “The Intelligent Investor.” In particular, he highlighted Chapter 8, which introduces the concept of “Mr. Market.” According to Graham, Mr. Market is an erratic and unpredictable figure, prone to irrational behaviour akin to a “psychotic drunk.” Buffett emphasizes that investors should view Mr. Market as a partner rather than an advisor, seizing opportunities when prices deviate from intrinsic value.

In essence, Buffett’s perspective underscores the importance of recognizing and capitalizing on market fluctuations, leveraging them to make sound investment decisions, especially when stocks in rare instances sell at “silly prices.”
