The "Oracle of Omaha," Warren Buffett, doesn't keep his financial advice a secret. There are certain habits he's warned about, especially if you want to build long-term wealth.

While he's not known to give tips just for the 50+ crowd, much of his wisdom is especially useful for those soon to enter retirement. Read on to see what surprising money mistakes he's hoping you'll avoid—no matter your age or stage in life.

Set up eligible direct deposit - pocket up to $400

Set up an eligible direct deposit with SoFi Checking and Savings and you could earn a bonus of $50 or $400.1 Make the switch, set up eligible direct deposit, earn the bonus. It basically takes no extra work at all other than following these steps. 

Why people are switching: This account earns up to an insane 4.20% APY2on savings for up to six months (3.30% APY standard + 0.90% APY boost) on top of that $50 or $400 bonus.1 That's way better than the measly 0.38% APY (as of 06/15/26)3 national average savings accounts offer.

Never panic-sell

Do you know the difference between a temporary market-price decline and a permanent loss? Buffett has embraced a long-term ownership mindset, even mentioning to shareholders that major price drops are to be expected.

Practically speaking, selling after a market dip instead of holding can turn your unrealized loss into a realized one. This broad strategy is especially important for those over 50, who can be vulnerable to fear-based selling as they watch retirement account balances fluctuate.

Instead of making emotional decisions, consider safer, more accessible money for near-term spending. That way, it's less likely that you'll need to sell long-term investments in a downturn.

Never invest in what you cannot explain

According to Buffett, investors should look for an understandable business with an attractive price, favorable long-term prospects, and honest and competent management. This first criterion strongly suggests it's not a good idea to commit retirement assets to trendy investments alone.

The same goes for complicated private deals or shiny investment pitches without any clear explanation of how they work. This guideline doesn't require you to analyze individual stocks, however; if you don't want to evaluate companies in this way, diversified funds may be a more simplified route.

Never borrow to invest

In another letter to Shareholders, Buffett clearly states that "Berkshire shares should not be purchased with borrowed money," because a sharp decline could be disastrous for speculators using leverage.

While this isn't a condemnation of all types of borrowing, it does have relevance for older households. Taking on investment debt near retirement adds a required payment just as employment income becomes less likely. Fixed income, like Social Security, does more of the work. This leaves your assets (including investments) at risk of needing to be sold to pay the monthly bills.

Never try to predict the market

Market timing is simply moving money in and out based on what experts predict might happen in the short term. It's selling off stocks before they dip or buying up those that speculators see going up.

Buffett's advice via a shareholder letter repeatedly distinguished between long-term business value and short-term stock price fluctuations. While monthly and yearly stock movements can be erratic, they don't always capture the changes in intrinsic value.

So, prices do matter, but investing is built on price discipline. For those in their 50s, this can mean choosing age-appropriate allocations, automating contributions, and rebalancing where appropriate.

Never ignore costs and fees

Fees are one of the few investing variables a person can see and control—even without years of experience. Small fees may seem small in comparison to the entire portfolio but still reduce returns year after year.

In a shareholder letter, Buffett wrote that he had instructed the trustee for his wife's benefit to put 90% of the cash in a very low-cost S&P 500 index fund and 10% in short-term government bonds. He believed the trust's long-term results would exceed those of most investors—including pension funds, institutions, and individuals—who employ high-fee managers. This exact allocation may not work for you, but the general idea of reviewing expense ratios, advisory fees, and fund costs (especially in your 50s) makes sense for those in a wealth-building mindset.

Never invest money you may need soon

Buffett's shareholder letters frequently discuss how important it is to maintain liquidity and avoid financial structures that require forced action at the wrong time. Money needed for expenses soon shouldn't depend on the stock market being up on a particular day or month.

For those over 50, this principle has an important application. Near-term needs, such as planned retirement withdrawals or health-care out-of-pocket costs, should be separated from long-term investments and not stuck in assets you can't reach.

The right amount of accessible liquid buffer depends on your monthly expenses and fixed income, as well as your projected timeline for large projects or medical bills. This number can change as you age, so estimate generously to ensure you always have enough in the bank.

Bottom line

Buffett's advice for shareholders has a theme of staying patient and poised for opportunity. He discourages emotional, trend-based, or high-cost investments and stresses deliberate and well-thought-out risks with a long-term trajectory for success.

Even if you don't own Berkshire stock, you can benefit from this sage wisdom. The 50s make an excellent time to add up what you might be able to keep earning before you retire, and make the right moves to balance your investments for your upcoming retirement reality. If you need help, don't hesitate to enlist the help of an experienced professional planner.
