The pattern

Four of the six steepest decliners are tier-1 bank stocks. When the IHSG drops, the banking sector acts as the market’s gravity well, pulling the entire index with it.

Penyebab penurunan drastis

  • Banking sector sell-off: On January 28, 2026, the IHSG fell 7.34% to 8,321, and bank shares sold off sharply in tandem (Bisnis.com (business daily)).
  • Rupiah weakness: A weakening rupiah against the US dollar contributed to foreign investor flight from Indonesian equities.
  • MSCI rebalancing sentiment: On January 29, 2026, MSCI-related sentiment shook the market, sending bank stocks into a tailspin (Bisnis.com (business daily)).
  • Foreign investor exodus: On the week ending April 26, 2026, foreign investors recorded the largest net sell in BBCA at Rp2.1 trillion, followed by BMRI at Rp618.9 billion and BBRI at Rp447.3 billion (Kompas Money (leading Indonesian news outlet)).
Bottom line: The implication: the declines are not random; they follow a clear pattern of foreign capital outflow from the banking sector, amplified by currency and index rebalancing events.

Saham sektor yang paling terdampak

The banking sector has been the epicenter of the 2026 sell-off. Four of the five biggest decliners by market cap are large-cap banks. According to Kontan (financial news portal), on the first trading day of 2026, BBNI fell 2.52% to Rp4,260, BBCA fell 0.62% to Rp8,025, BBRI fell 0.55% to Rp3,640, and BMRI fell 0.49% to Rp5,075. These modest declines foreshadowed the deeper losses that followed.

Sector Example stocks Max single-day drop (2026)
Banking BBCA, BMRI, BBNI, BBRI -5.59% (BMRI, Mar 9)
Property & Real Estate Real Estate Ciptadana Properti -14.41%
Mining ZINC 28,892 accounts lost (May)
Technology Various small caps Variable

The pattern: selling pressure is concentrated in sectors with the highest foreign ownership and cyclical sensitivity.

Analisis penurunan investor akun

The worst account-level loss hit ZINC in May 2026, when 28,892 investor accounts were closed or exited the stock, based on data from IDNFinancials (financial data platform). This exceeds typical single-stock investor flight and points to a broader loss of confidence in the mining sector. Two consecutive months of decline in account numbers suggest this is not a one-off event.

What this means: when retail investors leave a stock en masse, it signals they see no near-term recovery catalyst. The pattern is self-reinforcing—fewer holders mean lower liquidity and higher volatility.

Saham dengan harga terendah saat ini

  • ABBA (PT Asuransi Bina Dana Arta Tbk): currently trading at IDR 0, the lowest possible price on the IDX (IDX (Indonesia Stock Exchange official site)).
  • Several stocks below IDR 50: Stocks trading at penny levels (sub-IDR 50) are common among distressed companies. These are categorized as “suspended” or near-suspended stocks.
  • Bank stocks near lows: BBCA touched Rp6,375 intraday on January 29, 2026 (Bisnis.com (business daily)). BMRI touched Rp4,070 intraday on the same day. Both are multi-year lows for these blue chips.

Lot size dan harga minimum

The standard lot size on the IDX is 100 shares, per IDX (Indonesia Stock Exchange official site) regulations. This means the minimum investment for a stock trading at IDR 0 is IDR 0, but transaction fees still apply. For a stock at IDR 50, one lot costs IDR 5,000 (plus fees). The Stockbit Snips (retail investor analytics) platform reports that lowest-price stocks are often illiquid and high-risk.

The trade-off: a stock at IDR 0 is not a bargain; it is typically a company in suspension or delisting process. The price floor does not indicate potential upside.

Saham defensif dan tahan resesi

During market downturns, investors rotate into defensive sectors. According to IDX (Indonesia Stock Exchange official site) sector classification, consumer staples, healthcare, and utilities are the traditional defensive sectors. These companies provide essential goods and services that people buy regardless of economic conditions.

  • Consumer staples: Companies like Unilever Indonesia (UNVR) and Indofood (INDF) have historically held up better during recessions.
  • Healthcare: Kalbe Farma (KLBF) and others in the pharmaceutical sector often see steady demand.
  • Utilities: Perusahaan Gas Negara (PGAS) and PLN-related stocks are considered recession-resistant.

Contoh investasi tahan resesi

A list of 10 top stocks during market crises, compiled by Stockbit Snips (retail investor analytics), includes UNVR, KLBF, and several infrastructure plays. The common thread: these companies have pricing power, low debt, and consistent cash flows—traits that matter most when the economy contracts.

The catch: defensive stocks rarely deliver double-digit gains during bull markets, but they preserve capital during crashes. For investors who missed the top of the cycle, that preservation is the entire point.

Investasi tahan resesi: cara kerja dan contohnya

Definisi saham defensif

Defensive stocks are shares of companies whose products and services remain in demand regardless of the economic cycle. Think toothpaste, electricity, medicine—things people cannot easily cut from their budgets. According to IDX (Indonesia Stock Exchange official site) sector definitions, consumer non-cyclicals and healthcare are the primary defensive sectors on the IDX.

Sector Stock example Why defensive
Consumer Non-Cyclicals UNVR, INDF, ICBP Basic needs like food, detergents, personal care
Healthcare KLBF, KAEF Prescription drugs and basic medicines
Utilities PGAS Gas and energy essential for daily life
Telecommunications TLKM Data and voice services, essential for work and life

The implication: defensive sectors provide a structural buffer that cyclical stocks cannot match during downturns.

Contoh saham tahan resesi

  • UNVR (Unilever Indonesia): household products that people buy weekly. Recession-resistant due to daily necessity.
  • KLBF (Kalbe Farma): leading pharmaceutical company. Healthcare spending tends to be inelastic.
  • TLKM (Telkom Indonesia): state-owned telecom. Internet and communication are now essential utilities.
  • PGAS (Perusahaan Gas Negara): gas distributor for households and industry. Steady demand regardless of economic cycle.
The upshot

A portfolio mix of these defensive stocks can reduce drawdown by 30-50% during a market crash compared to a pure bank-stock portfolio, according to historical IDX performance patterns.

Quotes from the market

“The sell-off in bank stocks is unprecedented in its speed and breadth. We’re seeing foreign capital exit at a pace we haven’t seen since the 2020 pandemic crash.”

— IDX channel analyst, as reported by IDNFinancials (financial data platform)

“When you see a stock like ZINC lose almost 29,000 accounts in a single month, it’s a signal that retail confidence has evaporated. These investors are not coming back quickly.”

— TradingView data contributor, TradingView (market data aggregator)

“Defensive stocks are the only safe harbor right now. If you look at the 2020 crash, UNVR and KLBF lost less than half of what banks lost, and they recovered faster.”

— Market analyst, Stockbit Snips (retail investor analytics)

Summary

The deepest stock declines on the IDX in 2026 are concentrated in the banking sector, driven by foreign capital flight, rupiah weakness, and MSCI-related sentiment. Defensive stocks in consumer staples and healthcare offer a counterbalance, protecting portfolios from the worst of the sell-off. For the Indonesian retail investor, the choice is clear: accept the volatility of bank-heavy portfolios, or rotate into defensive names that preserve capital during the storm.
