When the company that produces the Standard & Poor’s 500-stock index announced this month it would exclude the corporate parent of Snapchat from its benchmark market measure, the move was cheered by advocates of better corporate governance.
It was seen as an overdue response to a disturbing trend, particularly in tech: Founders, when they take a company public, do whatever they can to maintain control, even when they own relatively small stakes.
In the case of Snap Inc., it had issued only non-voting shares in its March initial public offering — as far as it gets from many investors’ ideal of all shares having equal voting power.
But it’s far from clear that the stand taken by S & P will have much effect, even though inclusion in the index boosts a stock price by five percent on average.
“There is a lot of evidence that company management won’t care,” said Chris Jones, the former chief investment officer for asset management giant BlackRock’s domestic equity business.
Jones, now a member of the investment committee at Irvine, Calif., investing startup Acorns, said the new rules might persuade some small companies to change how they plan to go public. That’s not so for big, well-known businesses in which investors are clamoring to invest.
“When Uber comes public, they’ll come with some kind of differentiated structure,” he said.

The S & P rules say that companies with more than one class of stock will not be eligible to join its benchmark S & P 500, MidCap 400 and SmallCap 600 indexes, which track large, mid-size and small companies, respectively. Companies already included in the indexes, however, will be able to remain.
The announcement followed a similar rule change by FTSE/Russell, which plans to exclude companies from its indexes, including the Russell 3000, if they severely limit the voting rights held by ordinary shareholders.
Over the past decade and a half, numerous companies — including Google, Facebook, Workday and LinkedIn — have gone public with two classes of stock. One, owned by founders and early investors, carries outsize voting rights — often 10 votes per share. The other, sold to everyone else, has just one vote per share.
When Snap went public in March, it took things one step further, selling shares to the public that came with no voting rights at all. That prompted S & P, FTSE/Russell and another index manager, MSCI, to ask investors whether Snap’s non-voting shares or shares of other companies with little or no voting power should be included in their indexes.
Most investors, according to the results of polling released by FTSE/Russell, said the indexes should include only companies that give ordinary shareholders meaningful voting rights.
When companies are included in major indexes, investment funds that seek to match the returns of a particular index are forced to buy shares — something some investors don’t like.
Aeisha Mastagni, an investment officer at the California State Teachers’ Retirement System, told the Los Angeles Times this spring that investing in Snap would encourage “bad behavior” but that the huge pension fund would nevertheless have to buy Snap shares if they were included in the Russell 3000.
Forced-buying by index-tracking funds is one of the big benefits of index inclusion, especially as index funds have become more popular than ever. Vanguard, a pioneer in index fund investing, has seen hundreds of billions of dollars flow into its index-tracking funds over the past few years.

Still, there’s much more cash in actively managed funds, meaning there’s plenty of capital that can be invested in companies shut out of major indexes — and that the benefits of being included in the indexes may not be enough to persuade company founders to give up more control.
If companies don’t heed the new rules and continue to go public in ways that will keep them out of the big indexes, it eventually could make the indexes less attractive to investors.
For decades, the S & P 500 has been used as a gauge of what the U.S. stock market is doing. And index funds that track the S & P 500 are billed as a way to essentially invest in the whole market, or at least in the largest public companies.
But imagine if S & P had issued its new rule years ago and that companies such as Facebook and Google parent Alphabet never became part of the S & P 500.
According to an April report from investment firm State Street Global Advisors, if those and other companies with dual-class share structures were excluded from the S & P 500, the index’s returns would have fallen from 86.5 percent to 84.6 percent over the past decade. That’s because businesses such as Facebook and Alphabet have had outsize growth, boosting the index’s overall return.
