PT Buana Artha Anugerah Tbk (STAR) Stock Analysis 2026: Is This Indonesian Investment Holding Worth Buying?
 |
| PT Buana Artha Anugerah Tbk (STAR) |
Worldreview1989 - PT Buana Artha Anugerah Tbk (IDX: STAR) has become an unusual small-cap Indonesian stock story. The company has moved away from its historical trading business toward investment management and holding-company activities, while its earnings have increased sharply in 2025 and 2026.
For U.S. investors looking at Indonesian equities, however, the most important question is not simply whether STAR's earnings are growing. The bigger question is whether those earnings are sufficiently recurring and cash-backed to justify the stock's valuation and extreme price volatility.
Important name change: In 2026, the company became PT Calculus Global Ventures Tbk, formerly PT Buana Artha Anugerah Tbk. The stock ticker remains STAR. The company's June 2026 financial statements explicitly identify it as PT Calculus Global Ventures Tbk, formerly PT Buana Artha Anugerah Tbk.
Investment view: Speculative / High Risk — not a conventional value stock.
What Is PT Buana Artha Anugerah / Calculus Global Ventures?
The company was originally established as PT Star Asia International in 2008 and later became PT Star Petrochem. It went public in 2011. Historically, the company operated as a large trading business involving yarn, cotton and fiber.
The business model subsequently changed. According to the company's own corporate history, starting in 2018 it developed an investment-manager business through a subsidiary, and in 2019 the listed company changed its name to PT Buana Artha Anugerah Tbk.
The company's website describes its focus as investment management, particularly asset management, through its subsidiaries.
This makes STAR fundamentally different from a traditional industrial or consumer company.
For an American investor, it is more useful to think of STAR as a small Indonesian investment/holding company with asset-management exposure rather than as a conventional operating corporation.
2026 Name Change: Why Investors Should Pay Attention
The company's February 2026 extraordinary shareholders meeting included proposals involving changes to the articles of association, company name and board composition.
The company subsequently became PT Calculus Global Ventures Tbk.
The February 2026 shareholders meeting was attended by shareholders representing approximately 83.595% of voting shares, and the resolutions concerning the company's articles of association received overwhelming approval.
The June 2026 financial statements now use the name PT Calculus Global Ventures Tbk, formerly PT Buana Artha Anugerah Tbk.
For investors, this creates an important distinction:
STAR is still the relevant ticker, but searching only for "Buana Artha Anugerah" may cause investors to miss newer corporate disclosures.
STAR Financial Performance: 2025 Was a Major Improvement
STAR's reported financial results improved dramatically in 2025.
| Metric | FY 2024 | FY 2025 | Change |
|---|---|---|---|
| Revenue | Rp4.06 billion | Rp6.62 billion | +63.0% |
| Net income | Rp4.23 billion | Rp22.95 billion | +441.8% |
| EPS | Rp0.88 | Rp4.78 | +442% |
| Operating income | -Rp4.45 billion | -Rp1.39 billion | Improved |
The financial database compiled from company filings shows revenue rising from approximately Rp4.06 billion in 2024 to Rp6.62 billion in 2025, while net income jumped from Rp4.23 billion to Rp22.95 billion.
At first glance, these numbers look extremely attractive.
A U.S. investor might see:
Revenue +63%
Net income +442%
EPS +442%
and conclude that STAR is experiencing explosive growth.
That conclusion, however, requires caution.
The Biggest Financial Question: Why Is Net Income So Much Larger Than Revenue?
This is arguably the most important issue in the STAR investment thesis.
FY2025 revenue was approximately Rp6.62 billion, while net income was approximately Rp22.95 billion.
That produces a reported net margin of more than 300%.
This is obviously not a normal operating margin for a conventional business.
Investing.com reports the same unusual relationship, with FY2025 revenue of approximately Rp6.62 billion and net income of Rp22.95 billion.
For an American investor accustomed to evaluating companies such as JPMorgan, BlackRock, Berkshire Hathaway or Charles Schwab, this should immediately trigger a deeper examination of non-operating income, investment gains, fair-value movements and other accounting items.
The key question isn't:
"Did STAR make Rp22.95 billion?"
The better question is:
"How much of STAR's Rp22.95 billion profit is recurring cash-generating operating profit?"
That distinction could determine whether the stock deserves a premium valuation.
2026 Earnings: Still Strong, But Quality Matters
The company's 2026 earnings continued to show strong reported profitability.
For the second quarter of 2026, STAR reported approximately Rp3.88 billion of net income, up around 74% year over year according to compiled earnings data.
For the first quarter of 2026, reported net income was approximately Rp4.91 billion, versus approximately Rp2.79 billion in the comparable period of 2025, with EPS rising from about Rp0.58 to Rp1.02.
That means the earnings trajectory remained positive.
However, the company also continues to exhibit an unusual relationship between revenue and profit.
The latest financial data show approximately:
TTM revenue: Rp7.7–8.3 billion
TTM net income: around Rp24.5 billion
TTM EPS: approximately Rp5
Operating income: still negative in some reported periods
Operating cash flow: weak/negative
The financial data compiled from company filings show FY2025 operating income remained negative at approximately Rp1.39 billion, despite net income of Rp22.95 billion.
That is a major analytical warning sign.
Cash Flow Is More Important Than EPS
One of the most useful lessons from U.S. equity analysis is:
Earnings are an accounting measure; cash flow tells you whether the business is actually producing cash.
STAR's historical cash-flow data deserve close attention.
For FY2025, operating cash flow was approximately negative Rp2.67 billion, while free cash flow was also negative.
This creates a significant divergence:
Net income: +Rp22.95 billion
Operating cash flow: -Rp2.67 billion
That does not automatically mean the earnings are fraudulent or incorrect.
It does mean investors should investigate the composition of earnings before assigning a high recurring earnings multiple to the company.
For STAR, earnings quality may be more important than earnings growth.
Balance Sheet: One of STAR's Strongest Features
The balance sheet looks considerably more conservative than the income statement.
Financial data show approximately:
Total assets: Rp540.8 billion
Total equity: Rp538.0 billion
Cash and investments: Rp536.6 billion
Total debt: approximately Rp1.0 billion
This produces an extremely low debt-to-equity ratio.
That is a significant positive.
In simple terms, STAR has a large asset/equity base relative to its operating revenue.
This means the company may be better analyzed as an asset-backed investment holding company rather than using only conventional operating-company metrics.
STAR Stock Price in August 2026
STAR has been extraordinarily volatile.
As of August 19, 2026, one market-data source showed the stock around Rp440, after closing at Rp418 on August 18. The reported 52-week range was approximately Rp36 to Rp895.
Another market-data source reported a market capitalization of roughly Rp2.0 trillion around August 18–19, 2026.
That is an enormous price range for a relatively small company.
For a U.S. investor, the lesson is straightforward:
STAR should not be treated like a low-volatility dividend stock.
It behaves much more like a speculative small-cap equity.
Valuation Analysis
Let's use an approximate share price of Rp440 and approximately 4.8 billion shares outstanding.
At Rp440:
Estimated market capitalization ≈ Rp2.11 trillion
Using FY2025 EPS of approximately Rp4.78:
P/E ≈ 92x
Using approximately Rp5 of TTM EPS:
P/E ≈ 88x
These are very high earnings multiples for a company with only several billion rupiah of annual revenue.
A market-data source reported approximately 4.8 billion shares outstanding, while the company's securities are registered through Indonesia's central securities depository.
This creates an important contradiction:
The bullish argument
If STAR can transform its asset base into substantially higher recurring earnings, today's valuation could potentially be justified by future growth.
The bearish argument
If a large portion of current earnings is non-recurring, investment-related or accounting-driven, the market may be assigning an excessive multiple to a very small operating business.
A Simple Scenario Analysis
Rather than predicting one exact target price, it is more useful to model several scenarios.
Assume normalized EPS eventually reaches:
| Scenario | Normalized EPS | P/E Multiple | Illustrative Value |
|---|---|---|---|
| Bear | Rp2 | 15x | Rp30 |
| Conservative | Rp3 | 20x | Rp60 |
| Base | Rp5 | 20x | Rp100 |
| Bull | Rp8 | 25x | Rp200 |
| Very Bullish | Rp10 | 30x | Rp300 |
These are illustrative valuation scenarios, not price targets.
At a market price around Rp440, the stock would require either:
much higher sustainable EPS,
a very high valuation multiple,
substantial asset monetization,
or a combination of all three
to justify the current market capitalization.
That is why valuation is currently one of STAR's biggest weaknesses.
What American Investors Would Like About STAR
There is limited English-language retail-investor discussion specifically focused on STAR, so it would be misleading to claim that there is a large body of U.S. investor reviews.
However, when the company is evaluated through the lens of issues commonly emphasized by U.S. investors, several positives stand out.
1. Strong recent earnings growth
Net income increased dramatically in 2025, while EPS also rose sharply.
2. Very low leverage
The company has a very small debt position relative to equity.
3. Large asset base
STAR's assets and equity are disproportionately large compared with its operating revenue.
4. Corporate transformation
The transition from its historical trading business toward investment/holding activities could potentially unlock value if management deploys capital effectively.
5. Potential catalyst from the new corporate structure
The transition to Calculus Global Ventures could represent a new strategic chapter for the company.
What Would Concern American Investors?
This is where STAR becomes much more controversial.
1. Extreme share-price volatility
Independent market analysis has highlighted substantial weekly volatility, with STAR at times moving much more aggressively than typical Indonesian stocks.
The 52-week range of roughly Rp36–Rp895 reinforces this point.
2. Earnings quality
The company generated much more net income than revenue.
That makes the composition of earnings critical.
3. Negative operating cash flow
FY2025 operating cash flow was approximately negative Rp2.67 billion despite reported net income of Rp22.95 billion.
4. High valuation
At approximately Rp440 per share, STAR's implied P/E is extremely high relative to normalized small-cap valuation multiples.
One third-party relative valuation model estimated a much lower fair value based on peer P/E multiples, although such models should be treated as reference points rather than definitive intrinsic values.
5. Small operating scale
STAR's annual revenue remains only several billion rupiah.
That means even relatively small changes in investment gains or other income can dramatically affect reported earnings.
Ownership and Control
Ownership concentration is another factor investors should monitor.
Recent market data indicate that CALCULUS INVESTMENT PTE. LTD. holds approximately 32.19% of the company, while the remaining shares are held largely by the public.
This is important because a strategic shareholder can potentially influence:
corporate strategy,
capital allocation,
acquisitions,
subsidiaries,
management appointments,
and future business transformation.
For minority investors, however, concentrated ownership also means they should pay close attention to related-party transactions and corporate-governance disclosures.
Is STAR a Dividend Stock?
Not currently.
Available market data show a 0% dividend yield, and dividend databases do not show a meaningful current dividend history.
Therefore, investors should not purchase STAR primarily for income.
The investment thesis is much more dependent on:
capital appreciation + corporate transformation + asset value + future earnings growth.
STAR vs. a Typical U.S. Value Stock
An American investor might compare STAR with a familiar value-investing framework.
| Factor | STAR | Typical Mature U.S. Value Stock |
|---|---|---|
| Revenue scale | Very small | Large |
| Debt | Very low | Usually moderate |
| Dividend | None/limited | Often available |
| Earnings growth | Very high recently | Usually moderate |
| Earnings quality | Requires investigation | Usually easier to model |
| Valuation | Very high on EPS | Usually lower |
| Volatility | Extremely high | Generally lower |
| Liquidity | Limited | Usually much higher |
| Corporate transformation | Significant | Usually lower |
| Risk | Very high | Moderate |
This comparison explains why STAR should not be approached like Coca-Cola, Berkshire Hathaway, JPMorgan or another established U.S. blue-chip.
What Could Make STAR Bullish?
There are several potential catalysts.
Catalyst 1 — Recurring asset-management income
If the company's investment-management activities begin producing consistent fee income, earnings quality could improve.
Catalyst 2 — Better operating cash flow
This would be one of the most important signals.
If net income remains high and operating cash flow turns consistently positive, the market could gain confidence in earnings quality.
Catalyst 3 — Successful capital deployment
STAR's large asset base creates potential optionality.
Management could potentially deploy capital into businesses capable of producing recurring returns.
Catalyst 4 — Corporate transformation
The transition to Calculus Global Ventures may eventually produce a more clearly defined investment/holding-company strategy.
Catalyst 5 — Earnings growth
If EPS grows substantially faster than the share price, today's valuation could gradually become more reasonable.
What Could Make STAR Bearish?
The biggest risk is that the market is pricing in too much future success.
If:
investment gains decline,
non-operating income falls,
operating losses continue,
cash flow remains negative,
EPS declines,
or management fails to create recurring earnings,
the current valuation could compress dramatically.
The stock's enormous historical price range demonstrates how quickly sentiment can change.
A Better Way to Analyze STAR
For investors considering STAR, I would monitor these seven metrics every quarter:
1. Recurring revenue
Does revenue grow independently of investment gains?
2. Operating profit
Can the company generate positive operating income consistently?
3. Operating cash flow
Does cash flow eventually follow reported earnings?
4. Investment gains
How much of net income comes from investments or other non-core activities?
5. Book value
Is book value per share increasing?
6. EPS
Is EPS growth sustainable?
7. Valuation
Does the share price rise faster than intrinsic value?
These indicators are more important than simply looking at the headline net-profit number.
Investment Verdict for 2026
My rating: Speculative / High Risk
I would not classify STAR as an obvious value investment at around Rp440.
The company has several attractive characteristics:
Positive
Strong reported earnings growth
Very low leverage
Large asset/equity base
Potential corporate transformation
Asset-management exposure
Significant potential upside if recurring earnings improve
But the negatives are equally important:
Negative
Very high valuation
Extremely volatile share price
Small revenue base
Weak/negative operating cash flow
Large gap between revenue and reported net income
Earnings quality requires deeper analysis
No meaningful dividend thesis
Limited English-language investor coverage
The strongest bullish argument is future transformation.
The strongest bearish argument is valuation versus sustainable operating earnings.
For a conservative U.S. investor, that makes STAR difficult to justify at its current valuation.
For an aggressive investor who understands Indonesian small-cap stocks and is willing to accept substantial volatility, STAR could be viewed as a special-situation/speculative transformation story.
Bottom Line: Is PT Buana Artha Anugerah (STAR) a Buy?
For conservative investors: No.
For income investors: No.
For traditional value investors: Not yet.
For speculative investors: Potentially interesting, but only with strict risk management.
The key question for the next few quarters is not whether STAR can report another large profit.
It is:
Can STAR convert its unusual earnings growth into sustainable operating profits and positive cash flow while maintaining or increasing book value?
If the answer becomes yes, the investment thesis becomes considerably stronger.
If the answer remains no, the stock's high valuation and extreme volatility could represent substantial downside risk.
For U.S. investors, the most appropriate approach is therefore to treat STAR as a speculative Indonesian small-cap investment rather than a conventional growth or value stock.
