Stocks Are Crashing—That’s a Great Reason to Sit Tight
The sudden sell off in Japanese equities and a surge in the VIX suggest the current rout is being exaggerated by trend chasers

The red numbers in your 401(k) today might appear to vindicate warnings about an artificial-intelligence bubble and infirm economy. But don’t tilt your portfolio toward full pessimism just yet.
The S&P 500 was down 3% Monday, with the Nasdaq falling even further. Investors have been selling the year’s best performers, concerned that disappointing second-quarter results from big technology companies such as Alphabet , Tesla and Intel are a sign that the AI frenzy is a fad. Also, consumer discretionary stocks have become the worst-performing sector in the S&P 500, as lacklustre labour-market reports have raised worries that the Federal Reserve made a mistake by waiting until September to cut interest rates.

Overseas, the Stoxx Europe 600 closed almost 5% below where it was a week ago, whereas the Swiss franc, a common haven asset, is up roughly 4%. The most eye-popping moves happened in Asia, though, where the Nikkei 225 plunged 12.4% Monday in the worst trading session since Oct. 20, 1987—the day that followed Wall Street’s infamous Black Monday.
Yet it is precisely the breakneck speed with which Japanese equities tumbled that should give most investors a reason to remain calm.
As a guideline, sudden market selloffs are less dangerous than those that unfold progressively over time. This is because investors who rationally price in bad economic data often do so slowly, as it trickles in. Flash crashes, conversely, are often a sign that some tidbit of bad news made speculative bets go awry, triggering a cascade of trades, many of them automated.
Japan is particularly prone to such reversals because interest rates there are so low that many investors use them to fund higher-yielding investments in other currencies. Whenever markets get jittery, these “carry trades” tend to unravel, pushing up the yen and hitting Japanese stocks, many of which are diversified exporters that do better when global growth accelerates. Amplifying this tendency, Japanese stocks had this year become extremely popular among global investors.

The timing of the rout also points a finger at the Bank of Japan , which last week decided to tighten monetary policy for the first time in 17 years with the explicit goal of boosting the yen. Investors who rushed to cover their bets then triggered the reversal of stretched trades elsewhere, including in the U.S.
One of the most striking features of the S&P 500 for most of this year has been its extremely low volatility. Until July, the Cboe Volatility Index, or VIX, was at 2019 levels, and kept sliding lower even as investors made big changes to their monetary-policy forecasts.
While the VIX is often dubbed Wall Street’s “fear gauge,” the options contracts it is based on often themselves influence volatility. Whenever investors make bets against market swings, as they have recently in the U.S. by buying lots of structured products , the banks that sell those options are forced to take the other side. These hedges then suppress volatility in the stock market.
The flip side is that whenever a panic breaks through this feedback loop, volatility skyrockets. As the stock market opened Monday, the VIX hovered above 50, making it the highest weekly jump since the onset of the pandemic, though it later fell below 40.
This suggests the selloff is disproportionate, especially looking at the historical record: 87% of the time, investors who bought the S&P 500 on days when the VIX closed at 30 or higher ended up making money a year later.
The second-quarter reporting season has brought mostly good news, with 78% of the S&P 500 firms that have reported so far beating analysts’ earnings estimates—compared with a 74% 10-year average. Both AI-related companies and the rest are reporting net income above what was forecast a month ago. Overall, the U.S. economy still looks robust: The unemployment rate has gone up because the labor force has expanded.
Also, looking at S&P 500 returns since 1994 shows that selling based on the previous day’s falls is a bad strategy. Electing to move into cash after large monthly declines fared better, but still less well than sitting tight.
This isn’t to say that concerns about an economic slowdown or high tech valuations aren’t warranted. Investors have reasons to diversify away from the AI trend or swap more cyclically exposed stocks for more “defensive” names. Indeed, selling out of stocks after particularly exuberant days and months has historically tended to be a winning move. But hindsight is a terrible guide to investing your savings.

Strong family financial planning can help reduce taxes and support younger generations. From intrafamily loans and asset gifts to inheritance disclaimers, strategic cooperation can create meaningful financial benefits—when families have the trust and structure to make it work.
Happy is the family whose members—parents, grandparents and grown children—trust each other enough to cooperate on shared goals, especially financial ones. When that is truly the case, Uncle Sam’s tax rules can help as well.
This matters especially now that mortgage rates are above 7%, and many families are looking for ways to help younger members. If the elders have resources and are confident younger ones can cooperate, a family loan could make homeownership possible while providing the elders with a useful income stream.
Other strategies can actually lower taxes, such as when funding 529 plans or Roth IRAs, or when someone inherits a traditional IRA with required withdrawals larger than they will need.
Here are three strategies useful for functional families.
It is perfectly legal for families to lend money to a relative for a down payment or even a private mortgage.
But it is important not to cut corners, says Ryan McKeown, a CPA with Modern Wealth Enhancement in Minnesota. If the loan is for a down payment, be honest with the mortgage provider and have a formal agreement. The lender owes tax on the interest payments received.
If the loan is for a private mortgage, both sides should have legal representation with a formal written agreement, including payment terms. The lender owes tax on the interest, and the borrower often can deduct it if he or she itemizes.
To avoid IRS trouble, the interest rate shouldn’t be lower than the agency’s Applicable Federal Rate at the time of the loan. Currently that is about 5% for loans longer than nine years; about 4.5% for loans three to nine years; and about 4% for loans three years or less. Currently, traditional mortgage rates are generally above 7%.
In addition, the lender could use the $19,000 annual gift-tax exemption (described below) to forgive some or all of the interest or principal annually. If both lenders and borrowers are married, that is up to $76,000 a year. There is no tax for the borrower on such forgiveness, because it is from a gift.
If you’re going this route, McKeown advises against having a fixed plan to forgive the debt. Instead, do it in one-off letters specifying the amount—and keep careful records. Otherwise the IRS might try to treat the loan as a taxable gift.
Powerful tax-saving moves for families often use gift-tax provisions. Under current law, anyone can give anyone else up to $19,000 of assets annually, free of gift tax. That means a married couple with three grandchildren could give them a total of $114,000 in 2026.
The gifts can be cash or other assets, like stock. For noncash gifts, the cost basis—which is the starting point for measuring taxable gain after a sale—“carries over” to the recipient. So if someone buys $1,000 of stock and gives it away when it is worth $5,000, the recipient’s cost basis is $1,000. If the recipient later sells the shares for $8,000, the taxable gain is $7,000.
Here’s an example showing how gifts could save a family taxes. Grandma is a widow of modest means, while her child and spouse have prospered. The couple has two children, and they want to contribute $5,000 to a 529 college-savings plan for each—but they need to sell stock to do it. Their tax rate on the sale would be 18.8%, and they would need to sell about $11,000 of stock.
However, Grandma’s federal tax rate on the stock sale is 0%. If the couple gives $10,000 of shares to Grandma, she could sell them, pay no tax, and fund the grandchildren’s 529 plans. This saves about $1,000 of tax.
These moves are legal, and they could be used in other ways, such as to help a young person fund a Roth IRA.
But trust among family members is essential: Under the law, givers can’t put conditions on a gift. Grandma could use her stock proceeds to take a cruise, but she makes 529 contributions instead.
Mark Sellner, a retired tax attorney and CPA living in Sarasota, Fla., uses this strategy. His children sell stock he gives them and fund 529 plans for his grandchildren.
The family’s tax savings aren’t huge, but he likes other benefits. The sales by his children don’t boost his adjusted gross income, which in turn could raise his Medicare Irmaa premiums or his 3.8% surtax on net investment income.
Sellner doesn’t worry about his children using the funds for another purpose.
“There can’t be any strings attached to gifts. Of course, it is up to us to decide whether to make them in the future,” he says.
Two caveats: The “kiddie tax” applies to most children under age 24, and it is levied at the parents’ rate on investment income above $2,700 in 2026. Consider this before making gifts to a young person.
Investors who give away stock also forgo the step-up, an important provision that exempts assets held at death from capital-gains tax.
Sellner knows he’s losing a step-up, but says, “The children could use a little more now. Why should they wait 20 years to get it?”
A disclaimer is a highly useful strategy in which one heir renounces an inheritance in favor of another heir. Assuming family members cooperate, this can save taxes.
Here’s one example. Dad died and had a large traditional IRA that he left to Mom. She has enough assets and income to cover her expenses, and she lives in a state with a stiff estate tax. The inherited IRA would put her estate over the threshold.
Also surviving are three young-adult children. If Mom disclaims all or part of Dad’s IRA within nine months of his death, that amount could go directly to the children. They will have 10 years to empty the account, and the family as a whole will likely save estate and income taxes.
Disclaimers have many key details, especially regarding beneficiary documents. Although heirs have great freedom in choosing what assets to disclaim, the rules about who gets disclaimed property are rigid. It is best if the original owner names tiers of heirs so that if one disclaims, the next recipient is clear.
