Beat the S&P 500 with stocks whose indexes crashed: Rob Arnott

In a Report titled “Rejected: The Benefits of Termination” In an article co-authored with Forrest Henslee, he said that stocks faraway from indexes ultimately outperform, while newly added stocks underperform.

“As it turns out, getting dumped from an index can have impressive benefits, just as a relationship breakup can sow seeds for personal growth,” they wrote. “Dumped companies and their shareholders perform surprisingly well on average, even better than the stocks they replaced.”

While the variety of stocks included within the index initially increases sharply, especially between the date a change is announced and the date it takes effect, the momentum quickly fades, in response to the report.

In the 12 months following the change, recent additions to the S&P 500 lagged the market by 1 to 2 percent from 1990 to 2022. In contrast, stocks exiting the S&P 500, Russell 1000 and Nasdaq 100 outperformed the broad market index by greater than 5 percent annually over the subsequent five years.

Because so many funds are based on widely followed indices, the deleted stocks are subject to massive selling pressure, which frequently results in significantly lower prices than before the choice.

“This sets the stage for an impressive recovery,” the report says.

An investor who holds a portfolio of shares of sold securities and has optimized it for the five years after the cancellation would have multiplied his assets by an element of 74 between the start of 1991 and the tip of 2023, the institute estimated.

Only a Nasdaq 100 investor could have achieved this performance, but he would have needed to endure heartbreaking downturns. Meanwhile, value investors within the S&P 500, Russell 1000 and Russell 2000 could be behind by 55 to 65 percent.

To be certain, the dumped stocks haven’t beaten the key indexes over the past decade, as the present growth-dominated bull market has put severe pressure on value and small-cap stocks, Arnott and Henslee noted.

“But the dominance of growth is likely to end, and when that happens, almost anything should beat the S&P 500 and Nasdaq-100,” they added.

To test these findings on today’s market, the consulting firm launched the Index of Research Partner Deletion (NIXT).

The company buys sold stocks from the market capitalization-weighted top 500 and top 1,000 indices, holds them for five years and rebalances them annually to attain equal weight.

“Over the past 30 years, stocks have recovered well after an index crash,” the report says. “We are curious to see whether they maintain this resilience in the decades to come.”

The NIXT fund builds on previous findings by Arnott, who expected in December 2020 that Tesla would lag behind the S&P 500 within the 12 months following its inclusion within the index.

Just six months later, the S&P 500 had risen 17 percent, while Tesla stagnated and shares of the divested company Apartment Investment and Management rose 44 percent.
