BIST 30 basket — last 9 days +0.48%
Equal-weighted basket of 30 stocks, normalized to the first seen price.

1. Market Summary and Overview

While the BIST 30 index is experiencing a strong recovery at the 16.369 resistance level, a significant change in market dynamics is being observed. The "cash protection" and "cautious stance" approach that dominated in previous weeks is evolving into a more selective buying strategy as technical signals strengthen. As the index recovers from its previous weakness, the momentum increase in leading stocks indicates a slight rise in market risk appetite.

Across the market, the effect of the "Up Step Rule" is beginning to be felt. However, for this upward movement to be sustainable, it is essential for the 16.369 level to be broken decisively and for volume to be directed to this area. Current data shows that the market is in a process of "exiting the oversold zone" but has not yet entered the "overbought zone". At this point, the most critical strategy for investors is to manage portfolio risk by selecting only stocks with technical signals and strong fundamental data.

Among the highlighted developments, the strong performance of the energy and banking sectors stands out. The outperformance of companies like Tüpraş and Akbank supports the index, while BİM stock in the retail sector proves its resilience to inflation. This picture offers investors the opportunity to stay in "safe haven" stocks while emphasizing the need to be cautious in stocks that increase risk appetite.

2. Sector-Based Evaluation

Market dynamics clearly show sector-based differentiation. The Energy and Petrochemical sector has gained strong momentum along with rising global energy prices and Germany's economic measures against China. Tüpraş (TUPRS) stands out as the leader in this sector with a 90% 60-day return. In the petrochemical sector, companies like Petkim (PETKM) and Şişecam (SISE) show resilience even under inflation pressure.

The banking sector is recovering as local financial conditions ease and resource support is provided to Halkbank. Akbank (AKBNK) and Garanti BBVA (GARAN) are market leaders, while Vakıfbank (VAKBN) also shows recovery signals. However, a cautious approach is required due to overall volatility in the sector.

In the retail sector, BİM (BIMAS) proves its resilience to inflation, while companies like Migros (MGROS) and Astor Energy (ASTOR) show weakness. In the automotive sector, Tofaş (TOASO) shows recovery signals, while Ford Otosan (FROTO) and Enka İnşaat (ENKAI) give strong buy signals.

In the Metal & Mining sector, companies like Kardemir (KRDMD) and Ereğli Demir Çelik (EREGL) are strengthening along with industrial production. In the defense sector, Aselsan (ASELS) is seen as a safe haven stock.

3. Technical Visual Analysis

5. Risk Map and Scenarios

Changes in market dynamics require new risk management strategies for investors. Under current market conditions, managing portfolio risk is the most important point due to high volatility and uncertainty. Particularly, fluctuations in energy prices and global recession expectations are creating risks in industrial and energy-intensive sectors.

Leverage should be avoided and cash ratios should be kept high. Stop-loss levels should be strictly adhered to; especially for stocks like THYAO (290 TL), BIMAS (415 TL) and KCHOL (210 TL), stop-loss rules must be followed to the letter.

In bearish scenarios, there is a possibility that the index will test the 16.369 support level. In this scenario, it is necessary to increase the cash ratio in the portfolio to remain flexible and to be prepared against geopolitical risks. Investors should balance risk/reward by selecting only stocks with strong technical and fundamental data.
