Sequoia The Risks of Concentrated Investing

One of the wise advice given on risk management is we don’t have put all your money into one basket. If we have 100 stocks of a portfolio and equal 1% allocation to each company then erosion into any company will affect the entire portfolio by 1%. Whereas if we have a 10% allocation to the 10 companies then erosion to any one company will affect the entire portfolio by 10%.

When we have concentrated our portfolio to the winning businesses then we will be a winner and if we have concentrated our portfolio to the losers then we also are losers.

Mr. Buffett has closed his partnership in the year 1969 and suggested Mr. Bill Ruane manage the capital of partners so that Mr. Bill Ruane has set up the Sequoia fund. During the dot-com bubble, Sequoia fund has lost ~16.50% whereas the S&P 500 gained 21% and NASDAQ gained 86%. But after the dot-com bubble in the year 2002-2002, Sequoia fund has gained by 29% whereas the S&P 500 lost value by 38%.

In the year 2010, Sequoia fund has started acquiring a position to the Valeant Pharmaceuticals which becomes the second largest position. And in the year 2011, it becomes the largest position of the fund which has overtaken Berkshire Hathway which was the largest position in the 20 years.

In the year 2015, many consider Valeant business practice as an unethical and after that, it caught under accounting fraud. As Valeant was the largest position of the Sequoia fund, the fund lost 9.03% whereas S&P500 gained by 8.44%. Sequoia fund has bought again when Valeant fall by 50% and Sequoia fund becomes the largest shareholder of Valeant. But Valeant fall by 90% and Sequoia fund has to sell the entire position of the Valeant. Sequoia fund’s assets have fallen from around $9million+ to $5million. A single stock becomes a reason for the fall of their asset massively.

For avoiding such impact, we need to write down our assumption for buying a business so that we can take an exit when our assumption started getting wrong. This practice helps us to reduce the effect of endowment bias towards the stock which we hold. This also reduces the emotional bias towards the stock and help us to protect our capital. I always make a write up of the entry and exit reasons for the investment which help me for making a better decision and reduce my emotional bias. After all such activities, we need to be thankful for the role of luck which can support us. Concentration is good till we stay within our predefined process, assumptions, rules, etc. When we go out of any of the mentioned, we need to pay huge tuition fees for the concentration.
