For fun I asked the Microsoft Bing AI this:

What are the investment risks of putting 75% of our net worth in Berkshire Hathaway?

That's a good question. Investing in Berkshire Hathaway (BRK.A or BRK.B) has many potential benefits, but also some risks that you should be aware of.

Some of the benefits are:

Berkshire Hathaway is a diversified conglomerate that owns many successful businesses in various sectors, such as insurance, energy, railroads, utilities, consumer goods, and technology. This reduces the exposure to any single industry or market downturn.

Berkshire Hathaway is led by Warren Buffett, one of the most respected and successful investors of all time. Buffett has a track record of delivering exceptional returns for shareholders over the past 50 years. He also has a clear succession plan in place, with Greg Abel as his likely successor as CEO.

Berkshire Hathaway has a strong balance sheet, with $145.4 billion in cash and equivalents as of March 31, 2023. This gives the company ample liquidity and flexibility to weather any economic shocks, pursue attractive acquisitions, or buy back its own shares.

Some of the risks are:

Berkshire Hathaway is a large and complex company that may face regulatory challenges or scrutiny from authorities. For example, it may be designated as a systemically important financial institution (SIFI) by the Federal Reserve, which could impose stricter capital requirements and oversight.

Berkshire Hathaway may miss out on some growth opportunities or trends that are outside its core competencies or circle of competence. For example, Buffett has admitted that he was late to invest in technology companies like Apple (AAPL) or Amazon (AMZN), and that he made a mistake by selling his airline stocks during the COVID-19 pandemic.

Berkshire Hathaway may suffer from a loss of reputation or trust if Buffett or his successors make any ethical lapses or poor investment decisions. For example, Buffett recently faced criticism for his involvement in the failed Kraft Heinz (KHC) merger, his support for Chevron (CVX) over a climate change proposal, and his silence on some social issues.

Ultimately, investing in Berkshire Hathaway depends on your risk tolerance, time horizon, and investment goals. You should do your own research and consult a financial advisor before making any investment decisions.
