What happens when your halal stock turns non compliant?

What actually happens when a halal fund has to sell a stock?

If you invest in an Islamic fund, there is some piece of mind knowing there is a shariah body overlooking it: what happens when a company you already own stops being Shariah-compliant? Does the fund sell it immediately? Do you lose your gains? And is there anything you need to do yourself?

As you can imagine, in finance and islamic finance, it's not quite black and white, and it varies depending on which fund you are in. I think there are four things to consider when it comes to this topic. I've tried to use examples to help illustrate these too.

1. Is it sold immediately?

Not necessarily, and the reason why depends on what caused the company to fail its screen in the first place.

There are two types of failure. The first is a business activity failure. Imagine a tech company that was previously just a software business, generating clean, permissible revenue. It then acquires a conventional lending arm, and suddenly a significant chunk of its income comes from interest. That is a qualitative change, and under MSCI methodology (which governs funds like the HSBC MSCI World Islamic ETF, HSBC MSCI EM Islamic ETF, and Invesco MWIM), a business activity shift like this triggers removal at the next index rebalancing event. It is as close to immediate as a passive fund gets.

The second type is a financial ratio failure. Think of a company that has slowly taken on more debt over time, nudging it closer and closer to the leverage threshold. Under S&P and Dow Jones methodology (which governs Invesco IGDA, Wahed DJIW, and the Schroder Islamic Global Equity Fund), a company does not get removed the moment it crosses the line. It only fails if it breaches the threshold for three consecutive review periods. That could mean staying in the fund for the better part of a year before it is formally removed.

For Wahed's funds specifically, there is an additional rule worth knowing: if a non-compliant stock is discovered to have been included in error, it must be removed within two business days of that discovery. That is one of the tighter timelines in the industry. Source: Wahed Prospectus (SEC filing) - https://www.sec.gov/Archives/edgar/data/1683471/000089418919002369/lift-waheed_485a.htm

2. Is there a holding period?

Yes, in practice there almost always is, even if no one calls it that.

Think of it like a planning application. The moment someone objects does not mean the building comes down that same day. There is a process, a timeline, and a defined window before anything changes.

For passive index funds, that window is the rebalancing schedule. MSCI, FTSE, and Dow Jones all review their Islamic indexes quarterly. So if a company fails its screen in month one, the fund (whether that is the HSBC MSCI World Islamic ETF, Invesco IGDA, or the Wahed S&P 500 Shariah UCITS ETF) may continue holding it until the next scheduled review, at which point the index removes it and the fund follows.

On top of that, MSCI's consecutive review buffer means a stock can technically remain in HSBC and Invesco MWIM funds across multiple quarters if the breach is borderline, before it crosses the threshold that triggers formal removal.

For individual investors picking stocks directly, a commonly cited practitioner rule gives 90 days to exit a stock that has become non-compliant. But it is worth knowing this is a market norm and board-level guidance, not a hard rule from AAOIFI or any index provider.

3. What happens to the gains?

This is where it gets really interesting, and where the timing of non-compliance matters enormously.

Picture this. You are holding a company that has been in your fund for three years. It has grown well, and your position is up 40%. Then the company fails its Shariah screen. What happens to that gain?

The answer depends on when the gain was made. Profits that built up while the company was still compliant can generally be kept. But any gains made after the date the non-compliance was formally announced must be donated to charity. It does not matter whether the overall investment is profitable. Even if you are down on the position as a whole, gains earned during the non-compliant window still need to be purified.

This is documented in the Foresters Financial product that invests into the Schroder Islamic Global Equity Fund, which explicitly states that purification of potential investment gains where companies become non-compliant is likely to result in payments to UK registered charities approved by the Shariah Supervisory Board.

The fiqh logic behind this is clear. SeekersGuidance notes that where the rightful owner of unlawful funds cannot be identified, scholarly consensus directs those funds to charitable causes. In a market context, there is no single counterparty to return the gain to, so charity is the default.

It is about the nature of the income during that period. Source: Borsa Istanbul Review, Dec 2022 - https://doaj.org/article/e212925e2df44f1aa14f553906dc311f

4. Does further purification still need to happen?

Yes, and this is perhaps the most overlooked part of halal investing. Purification is not a one-off event triggered only when a stock fails. It is an ongoing obligation, even for companies that remain fully compliant.

Here is why. Most Shariah-compliant companies still have a small amount of income that comes from impermissible sources, usually below the 5% threshold that keeps them in the compliant category. Think of a large consumer goods company that earns 3% of its revenue from a finance subsidiary. It passes the screen, but that 3% still needs to be cleansed. The investor is expected to donate that proportion of their returns to charity.

How the funds handle this varies considerably, and this is one of the most practical differences between them.

The HSBC MSCI Islamic ETF range (World, EM, Europe, Japan, USA) handles it at the index level. MSCI applies a dividend adjustment factor to all reinvested dividends, reviewed annually, and builds the purification directly into its total-return calculation. As an investor in these funds, the cleansing largely happens before the return reaches you.

Invesco MWIM follows a similar approach. The MSCI ACWI Islamic M-Series index includes a dividend purification mechanism where a portion of dividends attributable to non-compliant income is deducted and donated to charity at the index level before it flows through to the fund.

Invesco IGDA takes a notably different position. Income accumulated in the fund is not purified before being reinvested. Instead, Invesco explicitly states that investors may wish to make their own donations using a dividend-based purging method. The responsibility sits with you, not the fund.

The Schroder Islamic Global Equity Fund includes dividend income purification as part of its structure, with non-compliant income donated to charity. The fund has Amanie Advisors appointed as its Shariah Adviser to oversee this process.

Wahed (both the S&P 500 Shariah UCITS ETF and the Dow Jones Islamic World UCITS ETF) takes a middle path. They screen holdings on an ongoing and annual basis and provide investors with clear annual reporting on what needs to be purified. Their Shariah Committee (Shariah Review Bureau) signs off on all returns. The expectation is that investors use this reporting to make their own charitable donations.

So what does this mean for you as an investor?

The key takeaway is that not all halal funds handle this the same way. Some do the work for you inside the fund. Others provide the data and expect you to act on it. And in every case, if a company you hold turns non-compliant, there are real obligations around timing, gains, and purification that matter.

If you are unsure which approach your fund takes, the first step is to check its prospectus or fund factsheet. The second step is to speak to someone who understands both the investment and the Islamic finance dimensions.
