SRI-KEHATI and ESG Investing on IDX: How Indonesia's Sustainable Stock Indices Work

What the SRI-KEHATI Index Actually Measures

The SRI-KEHATI index tracks 25 IDX-listed companies screened for sustainable and responsible investment practices, built jointly by the Indonesia Stock Exchange and the KEHATI Foundation since 2009. Unlike a plain market-cap index, it filters out firms tied to weapons, tobacco, alcohol, gambling, and serious environmental or labor violations before ranking the survivors by ESG performance across several weighted categories.

The index rebalances twice a year, in May and November, using audited financial statements plus a KEHATI-run sustainability questionnaire covering governance disclosure, environmental management, and community relations. A company that scores well financially but skips the questionnaire, or discloses too little, gets dropped regardless of size, which keeps the list genuinely screened rather than a large-cap proxy dressed up as an ESG product.

Because only 25 names make the cut, the index stays concentrated in large, liquid blue chips from banking, consumer goods, and telecommunications, sectors that tend to have the disclosure infrastructure to score well. That concentration makes it easy to track but means it behaves more like a quality-and-governance filter on large caps than a broad sustainability benchmark covering the whole exchange, small caps included.

How Companies Get Selected Into the Index

Eligibility starts with a market capitalization and liquidity screen similar to other IDX indices, since a company has to be tradable enough for the index to be investable in the first place. From that liquid universe, KEHATI applies negative screens first, automatically excluding sectors considered incompatible with sustainable investing regardless of otherwise strong financial performance or growth momentum.

Surviving companies then complete or are scored against KEHATI's ESG questionnaire, covering environmental policy, labor practices, community engagement, corporate governance, and business ethics. Each category carries a weighting, and companies are ranked by combined score, with the top 25 entering the index at each semi-annual review after the full ranking process finishes.

A company already in the index is not guaranteed to stay there indefinitely. Falling ESG disclosure quality, a controversy, or a drop in liquidity can bump a name out at the next rebalance, which gives management teams a real incentive to keep sustainability reporting current rather than treating it as a one-time compliance exercise done years ago.

Reading the ESG Screening Criteria in Practice

The environmental criteria look at energy use, waste management, and emissions disclosure relative to industry peers, not absolute environmental impact, since a bank and a plantation company cannot be judged on the same physical footprint. This relative scoring is a big part of why banks and telecom names dominate the final list every rebalance cycle rather than heavier industrial names.

Governance criteria weigh board independence, related-party transaction disclosure, and shareholder rights, areas where Indonesian corporate practice varies widely between family-controlled conglomerates and professionally managed public companies. A stock can pass environmental and social checks and still get excluded on governance concerns alone, which happens more often than most retail investors expect when they first study the methodology.

Social criteria round out the score by looking at labor conditions, workplace safety records, and how a company engages the communities around its operations, especially for mining, plantation, and manufacturing firms whose activities carry direct social impact well beyond the factory gate or the head office boardroom in Jakarta.

• Negative screen: excludes weapons, tobacco, alcohol, gambling, and adult entertainment outright
• Environmental score: energy intensity, waste handling, and emissions reporting versus sector peers
• Social score: labor practices, community programs, and product safety disclosure
• Governance score: board independence, related-party disclosure, and audit quality

SRI-KEHATI vs Other IDX Benchmarks

The IDX also runs the IDX ESG Leaders index and sector-specific indices like IDXHIDIV20, but SRI-KEHATI remains the oldest and most referenced ESG benchmark because of its independent, foundation-run screening process rather than a purely quantitative scoring model built entirely in-house by the exchange itself with no outside oversight.

Compared to LQ45 or IDX30, which select purely on liquidity and market capitalization, SRI-KEHATI trades some diversification for a values filter. Investors who want blue-chip exposure with an ESG tilt tend to use it as a starting universe, then layer in fundamental analysis before picking individual names to actually hold long term.

The overlap between SRI-KEHATI and LQ45 is still substantial, since both favor large, liquid names, so the practical difference for a portfolio shows up less in which sectors are represented and more in a handful of large caps that fail the ESG screen despite strong liquidity and earnings growth every quarter.

Why Foreign Funds Track This Index

Global ESG mandates increasingly require emerging-market allocations to pass some form of independent sustainability screen, and SRI-KEHATI gives foreign asset managers a ready-made, third-party-vetted list of Indonesian names that satisfy compliance teams without requiring separate in-house ESG research on every single company in the portfolio.

This foreign attention matters for price action. Index-tracking ETFs and mandate-driven foreign funds tend to buy in a block around each May and November rebalance date, which can create short-term demand spikes in newly added names and selling pressure in names dropped from the list at that particular review.

Watching the rebalance calendar alongside foreign flow data on IDX gives an investor a rough sense of when passive demand is likely to show up, separate from the fundamental case for owning a stock, and the two signals should never be treated as the same thing when building a position.

Building an ESG Tilt Into an IDX Portfolio

Using SRI-KEHATI as a starting screen rather than a buy list is the more disciplined approach, since index membership tells you a company passed a governance and disclosure bar, not that its valuation or growth outlook is attractive today. Fundamental work still has to happen after the screen, not instead of it, before any capital moves.

A practical approach pairs the ESG screen with valuation metrics like price-to-earnings ratio and return on equity, then checks dividend consistency over several years, since many SRI-KEHATI constituents are mature, cash-generative businesses that are better suited to income-focused portfolios than to aggressive growth allocations chasing rapid expansion.

Position sizing still matters even within a values-screened universe, since concentration risk does not disappear just because every holding passed an ESG filter. Spreading exposure across banking, consumer, and telecom constituents avoids over-reliance on any single sector's earnings cycle inside an already narrow 25-stock index with limited breadth.

• Start from SRI-KEHATI or IDX ESG Leaders as the eligible universe
• Filter by valuation and profitability rather than buying the whole index
• Track the May and November rebalance dates for passive flow effects
• Combine the ESG screen with normal fundamental and technical analysis

Limitations of ESG Scoring in Indonesia

Self-reported sustainability data is still common across Indonesian issuers, and questionnaire-based scoring inevitably rewards companies with the resources to produce polished ESG reports, which tends to favor large, well-capitalized firms over smaller companies that may have genuinely lower environmental impact but far weaker reporting capacity and a smaller compliance team.

There is also no independent auditing standard forcing every claim in an ESG questionnaire to be verified the way financial statements are audited, so scores should be treated as a useful starting filter rather than a guarantee of actual sustainable practice happening on the ground at every single operating site.

Investors relying only on index membership as proof of sustainable behavior can be caught off guard when a controversy surfaces between rebalance dates, since a stock keeps its index status until the next semi-annual review even if new information emerges that would otherwise disqualify it immediately from the list.

The Takeaway on Sustainable Investing on IDX

SRI-KEHATI gives Indonesian investors a credible, long-running way to screen for governance quality and disclosure discipline among IDX blue chips, backed by an independent foundation rather than the exchange marking its own homework on sustainability claims made by the very companies it lists on the board.

Treat it as a starting universe, not a finished portfolio. Layer valuation, profitability, and dividend analysis on top of the ESG screen, and track rebalance dates separately from your fundamental thesis so you are not confusing passive foreign flow with a genuine change in a company's underlying outlook.

For investors who care about both returns and responsible corporate behavior, SRI-KEHATI remains the most established reference point on the Indonesia Stock Exchange, and StockPilot's screening tools can layer fundamental and technical filters on top of that ESG universe in a single, structured research workflow.
