A while back we wrote about how to make your own fund. The honest answer at the time was a spreadsheet, a screening app, and a lot of patience. That post ended with Amal's fund filter, which takes an existing ETF and strips out the non-compliant holdings.
Custom funds are the next step. You pick the stocks yourself, set the weights, and Amal treats the result like any other fund: screened on every save, invested on a schedule, rebalanced, charted against the market, and shareable with a link.
Key Takeaways
Amal's catalog is built around popular funds with the haram holdings removed. That covers most people, and it's still the fastest way to get a diversified halal portfolio.
But a filtered fund is still someone else's fund. There are a few situations where you want your own basket:
Until now the only way to do that on Amal was to buy the stocks individually and keep the weights balanced by hand. A custom fund does the balancing for you.
Open Create fund in the app and choose the custom builder. There are four steps.

You can also start from an existing fund. Pick an ETF or mutual fund from the catalog and its top 50 holdings come in, weighted like the original. Anything that fails your rules shows as blocked, and you remove it (or allow it) before you can save.
The summary panel next to the builder shows how many holdings are allowed by your rules and how many are blocked. Two toggles control the edge cases:
Doubtful is allowed by default and unrated is not. Your personal blacklist applies too, so a company you have excluded across your account is blocked here as well. A fund with a blocked holding can't be saved, so you can't accidentally build one that breaks your own rules.
The ratings come from the same screening methodology behind every Amal fund, certified by Amanah Advisors and re-audited yearly.
What happens if a stock goes non-compliant later?
Catalog funds sell the holding automatically. Custom funds don't. It's your fund, so we notify you and leave the decision to you. Compliance is re-checked every time you save, and rebalancing or editing the fund shows you the change before anything trades.
Once saved, a custom fund shows up alongside your other funds and gets the same machinery:
Every custom fund has a public page: performance against a benchmark, allocation and sector breakdowns, and a compliance badge on every holding. Returns are anchored to the date the fund was created, not a backtest window you picked after the fact.
Anyone with the link can copy the fund into their own Amal account in one click. Their copy applies their own blacklist and compliance settings before it saves, so your fund never overrides someone else's rules.
Copies stay linked to the original. When you edit your holdings, every copy picks up the change, and the share page shows how many people and copies a fund has. Someone who wants to run the same fund with two pots of money can hold up to ten linked copies.
Building, screening, editing and sharing are free on every plan, including a free account with no broker connected. Investing real money into a custom fund is a Pro feature.
Pro is a one-time payment for lifetime access. There is no subscription. It unlocks investing in custom funds, the full library of over 10,000 ETFs and mutual funds to filter, and priority support. Standard covers the guided Grow and Save portfolios if you would rather not pick stocks at all.
Selling and rebalancing are never gated. If your plan changes, you can always get your money out or bring your weights back in line.
