Asia & Australia – Weekly Performance Review
Bill Cara
For the Week Ending August 19, 2025
Investment Analysis
Regional Performance Summary
The Asian telecommunications and utility sector shows mixed performance across timeframes, with Indonesian telecommunications giant Telkom Indonesia emerging as the clear outperformer across all metrics. Weekly performance was modest overall, with gains ranging from 4.09% to losses of -1.83%. Monthly performance shows greater dispersion, while year-to-date results reveal significant divergence between winners and laggards.
Strongest Performers Analysis
Telkom Indonesia (TLK) dominates all performance tables, posting the strongest weekly (+4.09%), monthly (+18.65%), and year-to-date (+22.19%) returns. The company's AT/INV/Total scores of 50/140/190 represent the highest combined technical rating in the portfolio, signaling strong momentum across multiple timeframes. This performance aligns with positive developments in Indonesia's telecommunications sector, where digital transformation initiatives and strong broadband adoption continue to drive growth.
Tenaga Nasional Berhad (TNABY) shows consistent but modest gains across timeframes, with balanced technical indicators (AT: 7, INV: 0, Total: 7) suggesting neutral momentum despite positive fundamentals.
Weakest Performers Analysis
PTT Exploration & Production (PEXNY) exhibits significant weakness across all metrics, with particularly concerning monthly (-11.82%) and year-to-date (-26.39%) declines. The company's severely negative AT/INV/Total scores of -50/-150/-200 indicate persistent technical deterioration, likely reflecting headwinds in the energy exploration sector.
Airports of Thailand (AIPUY) shows the worst year-to-date performance (-40.2%), though recent stabilization is evident in weekly performance (+0.35%). Mixed technical signals (AT: 20, INV: -20, Total: 0) suggest a potential bottoming formation.
Anomaly Detection
One monthly anomaly was detected: Telkom Indonesia's 18.65% monthly gain exceeds the 12.5% threshold, flagged as "Monthly Anomaly" in the dataset. This exceptional performance coincides with positive sentiment toward Indonesian telecommunications infrastructure investments and digital economy expansion initiatives.
Technical Signal Analysis
Based on AT/INV/Total methodology:
BUY Signal: Telkom Indonesia shows strong alignment across all technical dimensions with a Total score of 190
HOLD Signals: Tenaga Nasional Berhad with neutral but stable indicators
SELL Signals: PTT Exploration & Production with severely negative indicators across all timeframes
Regional Outlook
The Asia-Pacific telecommunications sector continues to benefit from digital transformation trends and 5G infrastructure investments. Indonesia's market leadership position and strong domestic demand support the positive momentum in companies like Telkom Indonesia. However, energy-related equities face ongoing challenges from commodity price volatility and shifting energy policies across the region.
Investor Considerations
Monthly Anomaly Alert: Telkom Indonesia's 18.65% monthly surge warrants monitoring for potential reversion or continuation patterns. While fundamentally supportive factors exist, the magnitude of the move suggests elevated volatility risk.
Sector Rotation Signals: The pronounced divergence between telecommunications (positive) and energy exploration (negative) performance suggests ongoing sector rotation within Asian markets. Investors should monitor for potential reversal patterns or continuation of current trends.
Regional Risk Factors: Asian markets face ongoing geopolitical tensions and trade policy uncertainties that could impact telecommunications infrastructure investments. Currency fluctuations and regulatory changes in key markets like Indonesia and Thailand present additional consideration factors.
Technical Deterioration Warning: PTT Exploration's severely negative technical profile (-200 Total score) suggests potential for further downside momentum. The company's positioning near multi-year lows requires careful risk management for existing positions.
Airport Sector Recovery: Airports of Thailand's stabilizing weekly performance amid severe year-to-date weakness may signal early stages of sector recovery, though confirmation through improved technical indicators is needed.
Bill Cara Perspective
The Asian telecommunications landscape presents a compelling divergence story, with Indonesian market leader Telkom Indonesia demonstrating exceptional momentum across all measured timeframes while traditional energy plays like PTT Exploration continue their descent. This performance differential reflects broader structural shifts favoring digital infrastructure investments over conventional energy exploration assets.
Telkom Indonesia's commanding technical position, supported by strong domestic demand and a favorable regulatory environment, positions the company for continued outperformance. The monthly anomaly flag, while noteworthy, appears justified by fundamental improvements in Indonesia's digital economy trajectory and the company's market-leading position in Southeast Asia's largest telecommunications market.
Conversely, the persistent weakness in PTT Exploration highlights the challenges facing traditional energy exploration companies amid global shifts toward renewable energy sources and changing investment priorities. The company's technical deterioration across all timeframes suggests institutional selling pressure continues unabated.
The neutral positioning of Tenaga Nasional Berhad and Airports of Thailand reflects broader uncertainty in their respective sectors, with utility and aviation industries navigating post-pandemic recovery patterns and evolving regulatory frameworks. These positions warrant close monitoring for potential breakout or breakdown signals.
Regional telecommunications infrastructure investments remain attractive given Asia's continued digital transformation and 5G deployment cycles. However, investors must remain cognizant of geopolitical risks and currency exposure when positioning in these markets.
