Warren Buffett's company Berkshire Hathaway is sitting on a record amount of cash — should you follow his lead? Here's why everyday investors should think twice

Why over-investing in cash can be a bad idea

Although Buffett kept billions safe from potential loss this year, the Oracle of Omaha made clear that he doesn't believe cash is king.

"Berkshire will never prefer ownership of cash-equivalent assets over the ownership of good businesses, whether controlled or only partially owned,” he wrote in his 2024 letter to shareholders.

The problem with cash is that your potential return on investment is very limited. Even if you put money into a high-interest savings account or guaranteed investment certificate, it's unlikely you'll earn more than 5% annual interest, and it'll probably be much less. Given that the S&P 500 has consistently produced average annual returns above 10% in its history — despite the volatile nature of the stock market — choosing cash investments cuts your growth potential.

Let's not forget inflation can siphon the buying power of cash and lower the value of any returns. So, while putting money into cash can make investors feel safer during turbulent times, you might also end up losing ground if inflation is high.

How to decide where to put your money

So, where should your money go instead?

CNBC reported data from J.P. Morgan Asset Management that shows a traditional portfolio with 60% in stocks and 40% in bonds consistently outperforms cash in the long run. This is based on putting 60% of your money into an S&P 500 index fund and 40% into the Bloomberg US Aggregate Bond Index.

From 1995 to 2024, the performance of this 60/40 portfolio would beat cash on a one-month basis 65% of the time. On a six-month basis, it beats cash 75% of the time, and when looking at performance over a year, that number climbs to 80%. Finally, over a time horizon lasting 12 or more years, the 60/40 split portfolio outperformed cash 100% of the time.

A similar 60/40 portfolio also beat out a diversified portfolio of 11 different asset classes during the stock runup in 2024, according to Morningstar research cited by CNBC. The 60/40 portfolio gained 15%, while the diversified portfolio gained only 10%. However, as President Donald Trump's trade policies have shaken up the markets, diversified portfolios have so far done better this year, in large part because the price of gold is up more than 30%.

In times of uncertainty, many people feel comforted by holding cash. It may be wise, in such cases, to build up an emergency fund and keep it in a high-interest savings account. But if you already have enough cash socked away for a rainy day, consider putting that money in a portfolio and riding the waves.

Berkshire Hathaway can afford to have billions sitting on the sidelines earning low returns, waiting for an opportune time to make use of their cash. But you don't have to follow suit and miss out on potential gains. Even if the market continues to be volatile, a portfolio with a long-term outlook can help weather the storm and put you in a good position for recovery.
