Active shareholder investing means exercising the rights that come with owning shares instead of leaving them unused. Those rights are concrete: a share makes you a co-owner of the business, entitled to a share of its profits and a vote on how it is run. Most shareholders never cast that vote. Until recently, investors who owned index funds and ETFs had a fair excuse, because the fund manager voted on their behalf. That excuse has expired. Vanguard Investor Choice now covers 32 funds and roughly 22 million eligible investors, representing nearly $4 trillion in assets under management. The question is no longer whether you can act as an owner. It is what you want your ownership to mean.
A share is a legal claim on a business, not a ticket that pays out if the price rises. However small the stake and however far removed the holder, a shareholder is a co-owner. That is a matter of company law, not a figure of speech.
Ownership comes with three things attached. A claim on profits. A vote on governance. And association with everything the business does to produce those profits.
The third one is the one investors tend to skip. A company carries values, communicates them to employees and customers, and produces effects on the world that never appear on its income statement. A co-owner is connected to all three. Declining to have a view on them is not neutrality. It is a position, and it is the position most shareholders take by default.
No, and this is the strongest objection to the argument, so it deserves a direct answer.
When you buy shares of Chevron on the New York Stock Exchange, you buy them from another investor. Chevron receives nothing. No new capital reaches the company, and no project gets financed because of your purchase. That is correct, and it is worth stating plainly rather than talking around.
What it changes is the mechanism of financing. What it does not change is ownership.
After the trade settles you own a piece of the business. You receive its dividends. You hold its voting rights. You benefit from its profits regardless of how those profits were produced. None of that depends on whether your money reached the treasury.
The claim that buying on the secondary market ends your responsibility rules out far more than it intends. If it were true, financed emissions accounting would be incoherent, portfolio carbon footprints would measure nothing, and every stewardship program run by every asset manager would be built on a category error. The entire architecture of responsible investing rests on the premise that owning is a relationship, not a transaction. Either that premise holds or none of it does.
Causation and responsibility are separate questions. Your purchase did not cause the company's emissions. Your ownership makes you a party to them.
A shareholder has three responsibilities: keeping up with what the company does, reading the resolutions that arrive with the proxy, and voting them. None is demanding. None requires expertise, capital, or more than an hour a year. What they require is attention, and attention is the thing most shareholders never give. The three below are ordinary obligations of ownership, not activism.
Not quarterly earnings. What the business actually produces, where its revenue comes from, and what it leaves behind.
Every year, shareholders file proposals asking companies to disclose emissions, report on lobbying, or publish pay-gap data. Management files its own proposals on executive compensation and board composition. Both arrive in your proxy materials.
This takes minutes. Almost nobody does it. During the 2025 proxy season, more than 80,000 Vanguard investors made a policy selection through Investor Choice — against roughly 20 million eligible at the time, a participation rate near 0.4%.
The gap between what shareholders are entitled to do and what they do is where corporate accountability leaks away.
Management acts on the mandate its owners give it.
The mandate runs on a spectrum. At one end, profit at all cost, on the shortest horizon that shareholders will tolerate. At the other, building a durable business that makes things worth making and can still be defended in twenty years. Most companies sit somewhere between, and where they sit is not fixed.
Management reads that mandate from shareholder behaviour, not from shareholder opinion. Emissions reduction targets, capital projects that pay back over decades, supply chain investments that raise costs before they lower risk — all of these need owners who visibly want them and will hold the stock while they mature. Absent that signal, the quarterly earnings call is the only voice in the room.
Silence is read as a mandate too. It is read as consent to whatever the board is already doing.
Investors who own index funds and ETFs can now direct how their shares are voted. This is new, it is expanding quickly, and it removes the last structural reason for not participating.
The mechanism is called pass-through voting. Your fund manager holds the shares and casts the votes. Under a pass-through program, you select a voting policy in advance and your proportional share of the fund is voted according to it.
Vanguard Investor Choice is the largest retail proxy voting program in the world. Following its 2026 expansion it covers 32 Vanguard funds and approximately 22 million eligible investors, representing nearly $4 trillion in assets under management. Participating funds include the Vanguard 500 Index Fund and the Vanguard ESG U.S. Stock ETF.
Investors choose from a menu of five voting policies through a single election that then applies across participating funds.
Since March 2026, the program has run through Broadridge's ProxyVote.com platform, so investors who hold Vanguard funds at a third-party brokerage can participate without moving their account. Vanguard has stated it intends to extend Investor Choice to all its U.S. equity index funds by the end of 2027, which would take eligible assets to $6.4 trillion.
BlackRock launched Voting Choice in January 2022. As of 31 March 2026, index equity clients representing approximately $851 billion in assets under management were exercising it. The retail route is the iShares Core S&P 500 ETF.
Eligible investors in the U.S. retail fund select one of seven third-party voting policies, or BlackRock Investment Stewardship's own U.S. voting guidelines.
The gap between eligible and exercised is the notable figure here. Approximately $3.76 trillion of client index equity assets were eligible for Voting Choice as of 31 December 2025. Roughly $851 billion of that is being used.
State Street Investment Management's Proxy Voting Choice program now spans more than 600 funds across the United States, the United Kingdom, Luxembourg, and Ireland. More than 80 institutional clients globally have participated, representing roughly 10 percent of eligible institutional assets under management, while retail adoption among U.S. ETF and mutual fund investors rose 53 percent to over 29,000 shareholders.
Twenty-nine thousand shareholders. The infrastructure is built and almost unused.
If you make no selection, someone else's voting policy applies to your shares, and that policy has moved a long way in three years without asking you.
In the 2022 and 2023 proxy years, State Street supported 46% of environmental and social resolutions that had significant independent shareholder support. In 2024 that fell to 22%, against BlackRock at 12% and Vanguard at 0%. Across the 2025 proxy year, the three managers backed an average of 98.7% of management resolutions, up from 96.0% in 2023.
Vanguard's 0% was not a policy any investor selected. It was the one that applied by default.
Choosing a policy takes one election. Not choosing is also an election, made on your behalf, revisable by the manager without notice.
Ziggma does not vote your shares. Your broker and your fund manager run the voting infrastructure, and pass-through voting is the bridge between them and you.
What Ziggma does is the step that comes first. You cannot decide what you want from a company until you know what the company does.
Portfolio Checkup shows what you own across every connected account, with an Impact Score on each holding built on ACA Ethos data. Impact X-Ray breaks a fund open so you can see the underlying companies rather than a label. Global Warming Potential gives the temperature trajectory your portfolio is aligned to.
That is the raw material for a considered vote. Most investors reach the proxy without it.
