Warren Buffett and his mentor — Benjamin Graham — on what is now attributed to Charlie Munger as "sit on your ass investing".
Inactivity ≠ Assiduity
While Munger's "assiduity" quote has nothing to do with the inactivity principle, the idea of trading as little as possible is common among Value Investors.
"Lethargy bordering on sloth remains the cornerstone of our investment style."
"Inactivity strikes us as intelligent behavior."
"1) Investors, overall, will necessarily earn an average return, minus costs they incur; 2) Passive and index investors, through their very inactivity, will earn that average minus costs that are very low; 3) With that group earning average returns, so must the remaining group – the active investors. But this group will incur high transaction, management, and advisory costs. Therefore, the active investors will have their returns diminished by a far greater percentage than will their inactive brethren. "
"While enthusiasm may be necessary for great accomplishments elsewhere, on Wall Street it almost invariably leads to disaster."
"It is no difficult trick to bring a great deal of energy, study, and native ability into Wall Street and to end up with losses instead of profits."
"Since the most profitable customers want speculative advice and suggestions, the thinking and activities of the typical firm are pretty closely geared to day-to-day trading in the market. Thus it tries hard to help its customers make money in a field where they are condemned almost by mathematical law to lose in the end."
Inactivity is thus one of the hallmarks of Value Investors. Buffett's baseball analogy of no called strikes is another great example of this principle.
Buffett: Activity Is Overrated
Given below are videos of Warren Buffett and Ajit Jain's 2011 interview in India, in which Buffett says "activity is overrated". Some of the other important points made during the interview are:
- Getting to choose who you associate with is a luxury.
- A life free of mistakes is a life of inaction.
- Have the willingness to walk away from things that others think are simple.
- Have the discipline to say no and not follow the crowd, do your own research.
- The stock market is a game stacked in your favor, just don't play it too often.
- Volatility is the Value Investor's friend.

Seth Klarman on Inactivity
In the following video, Seth Klarman — chief executive of the Baupost Group — explains why they have a holding period of three to five years; citing an anecdote from Tweedy, Browne Company LLC which too has its roots in Graham Value Investing.
"In 1968, Tom Knapp and Ed Anderson, also a Graham disciple, along with one or two other fellows of similar persuasion, formed Tweedy, Browne Partners, and their investment results appear in Table 2. Tweedy, Browne built that record with very wide diversification. They occasionally bought control of businesses, but the record of the passive investments is equal to the record of the control investments."
