How to Understand The Small-Stock Rally

Small stocks so far this year have beaten their large-capitalisation brethren by a wider margin than they have in more than two decades, raising questions about what is driving the outperformance and what it means for the overall market ahead.

The year-to-date return for small-caps through the end of February was a remarkable 25 percentage points greater than that of large-caps (as measured by the 20% of stocks with the smallest market caps vs. the comparative quintile of the largest). While it isn’t unexpected for small-cap portfolios to beat large-caps over time—a long-term tendency that Wall Street analysts refer to as the “size effect”—what is unusual is the magnitude of the outperformance. It has averaged just 0.9 percentage point over all two-month periods since 1926, according to data from Dartmouth professor Ken French.

You have to go back to January and February of 2000, at the top of the internet-stock bubble on Wall Street, to find a two-month stretch in which the small-caps beat the large-caps by more. Their margin of outperformance over those two months was 41 percentage points.

Any parallel to the top of the internet-stock bubble is ominous, to be sure. But there are several idiosyncrasies to small-caps’ recent performance that stand in the way of drawing any straightforward analogies to the frenzy in small stocks that heralded the 2000 tech-stock crash.

Indeed, according to several researchers, small-caps’ recent strength may actually be something else in disguise—that is, it may have to do with factors other than just size, such as the battle between growth and value stocks.

That doesn’t mean there is nothing to worry about in this bull market, where valuations are stretched thin for many stocks. But it does mean that investors who are focused solely on the small-cap/large-cap divergence could be missing the bigger picture.

Here’s why.

1. Value versus growth

One distinction that is crucial for understanding the relative strength of small-caps this year has to do with where small- and large-cap stocks lie on the growth-versus-value spectrum. Small-cap stocks currently are far closer to the value end of the spectrum than large-caps, meaning they are trading for lower prices relative to their net worth.

A stock’s place on this spectrum is defined by its ratio of price to per-share book value, with the highest ratios at the growth extreme and the lowest at the value extreme. Consider the Russell Microcap Index, which contains the smallest 1,000 stocks in the broad-market Russell 3000 index. Its average price-to-book ratio was 2.5 as of the end of February, according to Russell Indexes. That compares with a 4.2 ratio for the Russell 1000 Index (which contains the largest 1,000 stocks) and a 5.7 ratio for the Russell Top 50 Mega-Cap Index (which contains the largest 50 stocks).

These are significant differences, according to Kent Daniel, a finance professor at Columbia University and a former co-chief investment officer at Goldman Sachs. He says that, on average, small-cap growth stocks tend to underperform the market, while small-cap value stocks tend to outperform. Since 1926, he says, the smallest-cap stocks closest to the growth end of the spectrum have lost 3.3% annualized, while the smallest most value-oriented stocks have gained 13.3% annualized.

This pattern has been especially strong in recent months, making it difficult to determine what accounts for small-caps’ relative strength this year. But Prof. Daniel says there is the distinct possibility that it is really a “value effect masquerading as a size effect.” If so, a bet on small-cap relative strength continuing is really a bet that value will outperform growth.

That bet may pay off in coming months, he says, and value could continue to outperform growth for many years. But he also says that value stocks have lagged behind growth stocks for at least a decade now, and while there have been numerous predictions of a value resurgence over that time, it hasn’t happened—at least not yet.

2. Sector bets

The benchmark indexes for small-caps and large-caps have different sector weightings, which also makes it difficult to gauge whether the recent relative strength of small-caps is actually due to company size.

Consider the information-technology sector. The ETF benchmarked to the largest 50 stocks currently has a 38.6% weighting to this sector, more than three times the 12.7% weighting of the Russell Microcap Index.

Conversely, the microcap index has more than 10 times the weighting of the largest-50-stock ETF to the industrials sector (11.7% versus 0.8%) and more than double the allocation to the financials sector (17.6% to 7.1%).

These differences are a big part of small-caps’ year-to-date performance, since industrials and financials have each outperformed the information-technology sector. It was just the opposite for calendar 2020, and sure enough, the smallest stocks lagged behind the largest last year.

Until there are small-cap and large-cap benchmarks with the same sector weightings—Prof. Daniel says he is unaware of any currently—it will be difficult to determine what is driving small stocks’ relative strength. If it is being caused by differences in sector weightings, however, it is likely to persist only if the sectors in which the small-caps are overweight continue outperforming.

3. Is the small-cap effect real?

This discussion also points to a more fundamental question that many researchers have been asking in recent years: Does the small-cap effect even exist, in and of itself? That is, do smaller firms really have higher returns than larger firms, on average, over long periods?

Andrea Frazzini, a principal at AQR Capital Management and an adjunct professor of finance at New York University, has concluded that it exists only among a very narrow group of stocks. He says that some of the relative strength of small-caps in recent months traces to speculative fervour for stocks outside that narrow group, making it risky to bet that it will continue.

According to his research, small-caps are a good bet to outperform the large-caps only if you limit your focus to companies with high financial quality. By financial quality he means firms that are profitable, have robust profit growth and a stable earnings stream and a high dividend-payout policy, among other characteristics. Many of the small companies that have performed the best so far this year don’t qualify.

Companies that have been bid higher in recent weeks through social-media investor campaigns—such as GameStop and AMC Entertainment—are two obvious examples, but they are hardly alone in not qualifying for Prof. Frazzini’s high-quality category. Nearly half of the 2,000 companies in the Russell 2000 small-stock index, for example, lost money in 2020.

Prof. Frazzini’s research therefore suggests that, if you want to bet on a continuation of recent small-cap relative strength, you should focus on small stocks that score high on various measures of financial strength, safety and quality. And don’t sweat the comparisons to that internet-stock frenzy of 20 years ago.

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.

Intrafamily loans

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.

Asset gifts

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?”

Disclaimers

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.
