Charlie Munger's Investment Strategy | The Motley Fool (2024)

With an estimated net worth of "only" $2.5 billion, Charlie Munger didn't even crack the top 1,000 on Forbes' list of billionaires before he passed away in 2023. However, Munger was still a well-known, respected, and successful investor. He was vice chairman of Berkshire Hathaway (BRK.A -0.54%)(BRK.B -0.72%), having served as Warren Buffett's right-hand man for decades.

Here's who Munger was, his investing style, and some of his top holdings.

Who was he?

Who was Charlie Munger?

After serving in the military during World War II and subsequently earning his law degree from Harvard, Munger went on to practice law in California. Later, he was a partner at his own law firm and did some work in real estate development.

Like Warren Buffett, Munger was from Omaha, Nebraska. But the duo didn't meet as children. Rather, they were introduced by a mutual friend in 1959 while Munger was visiting from California. From there, the two struck up a friendship.

While Munger was always interested in investing, encouragement from his new friend Warren Buffett caused him to take it more seriously. According to a writeup by Buffett called The Superinvestors of Graham-and-Doddsville, Munger ran his own investment fund from 1962 to 1975, earning 19.8% annually compared to just a 5% annual return for the Dow Jones Industrial Average during this time.

In 1965, Buffett took control of the New England textile company Berkshire Hathaway. Then, in the 1970s, Buffett brought Munger on at Berkshire. Munger later became vice chairman in 1978.

During his long career, Munger held positions at other companies as well. He was chairman of conglomerate Wesco Financial Corporation from 1984 through 2011 -- a now wholly owned subsidiary of Berkshire Hathaway. He was also chairman of publishing and technology company Daily Journal Corporation (DJCO 0.68%) from 1977 through 2022. He was also on the board of directors at bulk grocery chain Costco Wholesale (COST 0.11%), a position he held from 1997 through 2023.

Investment approach

Charlie Munger's investment approach

Charlie Munger's investment approach was predicated on the assumption that good opportunities are few and infrequent. As he once said, "Life is not just bathing you with unlimited opportunities."

Therefore, Munger's process wasn't about finding as many good ideas as he could. On the contrary, he sought to eliminate bad and mediocre ideas first. This might seem like a backward approach, but he often spoke about the value of inverting one's thinking.

Munger's preference toward thinking in reverse was clearly illustrated when he said, "It's remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent."

Because he believed good opportunities are rare, Munger decisively seized opportunities when he finally saw them. Quoting his great-grandfather, Munger said, "When you get a lollapalooza, for God's sake, don't hang by like a timid little rabbit."

Consequently, Munger didn't share widely held views on diversification -- even holding 10 stocks risks being over-diversified, in his opinion. After all, if good ideas are truly rare, then why would one diversify a portfolio into dozens of things? The positive impact of the good ideas would only be diluted from all of the mediocre investments in the portfolio.

Munger employed a buy-and-hold investment strategy. When he found a good idea, he simply continued to hold that stock and allowed compounding to work for him. As he said, "The big money is not in the buying and the selling, but in the waiting."

Finally, Munger was known to be a value investor, but there is an important distinction to be made. Whereas many value investors look for whatever is cheap regardless of the quality of the business, Munger was willing to pay more for quality.

In his 2014 letter to Berkshire Hathaway shareholders, Buffett credited Munger with changing his perspective on value investing. Buffett quoted Munger as saying, "Forget what you know about buying fair businesses at wonderful prices; instead, buy wonderful businesses at fair prices."

To summarize the investment approach, Munger believed that good investment opportunities are few, and therefore, he concentrated his portfolio around only those few good ideas, provided he could buy them for a fair price. Then, after he bought these, he simply held on for the long haul.

In wrapping things up, I'll point out that Munger admitted that a diversified portfolio is right for many investors. Munger once said, "The idea of diversification makes sense to a point if you don't know what you're doing."

Of course, no one likes to admit any ignorance. However, the more concentrated your portfolio is, the greater the risk of permanent loss of capital if you're wrong. It's not a strategy to use flippantly.
