Deep Analysis

1. Market Summary and Overview

As of 26 Ekim 2026 Pazartesi, saat 12:31, the BIST 30 (XU030) index is trading at 13,912.06 and records a 0.27% increase compared to the previous close; the BIST 100 (XU100) trades at 11,128.89 with a 0.11% appreciation. The Dollar/TL parity retreated 0.13% at the 49.67 level, bringing the indices' dollar-based performance to the 0.40% level. Although a slight recovery in global risk appetite during the day and Brent oil holding at 111.70 USD/varil supported the energy-heavy index, the pressured course in banking and holding shares caps the index's upside. On the macro front, Türkiye's annual consumer inflation for Eylül 2026 came in at 29.73%, while the policy rate was kept at 36.0% by the decision dated 22 Ekim; real rates remaining in negative territory and the budget deficit rising to 532.2 milyar TL'ye in Eylül indicate that financial conditions remain tight. Although the 10.1% year-on-year growth in retail sales in Ağustos signals resilience on the demand side, the 1.86% year-on-year decline in industrial production in the same period reflects weakness on the production side. Portfolio performance remains at %-14.87 since 6 Eylül 2026 and exhibits serious underperformance against the dollar, gold, time deposits, and index benchmarks.

2. Sector-Based Evaluation

Energy and Petrochemicals

Tüpraş (TUPRS) shares trading at 365.75 TL with a daily 1.39% increase and its strong 28.2% performance in 60 days constitute the sector's only bright spot; Wave Trend (WT) buy signal and the long-term trend being in "BUY" position indicates the technical structure remains intact. Petkim (PETKM) and Astor Enerji (ASTOR) meanwhile maintain weak trend structures with 60-day losses of %-6.0 and %-45.4 respectively, with daily changes of 0.66% and 9.96% (ASTOR recovery attempt); even though both stocks' WT indicators give a "BUY AT DIP" signal, the overall trend remains in the "SELL" zone. Enka İnşaat (ENKAI) is included in this group due to its energy activities, but remains under selling pressure with a 14.5% 60-day loss and proximity to the channel lower band (11%).

Banking and Holdings

While all banking index components (GARAN, AKBNK, ISCTR, YKBNK, VAKBN) give a "STRONG SELL" signal, channel positions remain at negative (VAKBN %-15, AKBNK %-3, ISCTR %-5) or low positive (YKBNK 8%, GARAN 10%) levels; Pearson correlation coefficients (r) hovering near zero or negative (AKBNK -0.30) prove they move out of sync with the index. Despite their holding structures, Sabancı Holding (SAHOL) and Koç Holding (KCHOL) trade nearly flat over 60 days (SAHOL +0.2%, KCHOL +0.9%) with "SELL" and "STRONG SELL" signals; this suggests that banking margin pressure in their core companies and declines in automotive subsidiaries (TOASO, FROTO) weigh heavily.

Automotive and Aviation

Ford Otosan (FROTO) and Tofaş (TOASO) are in a deep correction with 60-day losses of %-16.6 and %-18.8 respectively; even though both give a WT "BUY AT DIP" signal and RSI levels (FROTO 30.28, TOASO 26.93) have entered oversold territory, MACD and CCI indicate continuation of negative momentum. In the aviation group, THYAO (Türk Hava Yolları), TAVHL (TAV Havalimanları) and PGSUS (Pegasus) show 60-day performances of %-18.4, %-3.1 and %-20.7 with a "STRONG SELL" signal; THYAO's channel position at the 1% level (very close to the regression channel's middle) indicates the price is at a trend decision point.

Metal, Mining and Chemicals

Ereğli Demir Çelik (EREGL), Kardemir (KRDMD), TR Anadolu Metal (TRMET) stand out in the metal group with 60-day losses of %-23.9, %-8.4 and %-17.4; EREGL is in a deep downtrend with weak trend strength, with a channel position of %-33, CCI -347.72 and ADX 16.05. In the chemicals and fertilizer sub-sector, Gübre Fabrikaları (GUBRF) and Sasa Polyester (SASA) are in oversold territory with 60-day losses of %-30.7 and %-38.5 respectively and RSI levels of 22.02 / 26.22; however, CCI values (GUBRF -228.95, SASA -153.65) and MACD negativity indicate that technical recovery attempts have not yet begun.

Retail, Telecom and Others

BİM (BIMAS) and Migros (MGROS) retail stocks show 60-day performances of -0.2% and %-29.4 respectively with a "STRONG SELL" signal; MGROS is seen to be in a strong downtrend with RSI 25.21, CCI -136.1 and ADX 47.52. Türk Telekom (TTKOM) and Turkcell (TCELL) telecom stocks also show 60-day losses of %-13.4 and %-13.7 with a "STRONG SELL" signal; TTKOM's CCI -219.24 and RSI 28.48 levels indicate the price is leaning on the channel lower band (% -12). Şişecam (SISE) maintains a weak structure with a %-20.1 loss in the glass sector, while Türk Altın (TRALT) maintains a weak structure with a %-19.0 loss.

3. Technical Visual Analysis

EMA Alignments and Trend Structure

The "short/medium/long" columns in the scan data reflect the status of EMA alignments; in the vast majority of the market (27 stocks), short and medium-term EMAs are in a "SELL" position. Only TUPRS gives a "BUY" signal in the long-term EMA alignment, while SAHOL, ASELS, KCHOL, EREGL, TRMET, KRDMD remain in a "WAIT" or "SELL" range; this indicates that long-term trends have not yet turned, pointing to structural strength only in TUPRS. Channel positions (percentage position within the regression channel) show the price's relative place to the trend: TUPRS at 21% below the channel mid-band but with upside potential; SAHOL 48%, ASELS 41%, TAVHL 42% trading above the channel mid-band and in a position to test resistance. Banking stocks (VAKBN %-15, AKBNK %-3, ISCTR %-5) and metal stocks (EREGL %-33, KRDMD %-20, TRMET %-15) are near or below the channel lower band; although these levels appear technically "cheap", momentum confirmation (WT or MACD crossover) is required for a trend reversal.

Wave Trend (WT) and Pearson Correlation (r)

The WT indicator generates only a "BUY" signal for TUPRS, and a "BUY AT DIP" signal for ENKAI, FROTO, ASTOR; while giving a "SELL" signal for the remaining 26 stocks. The "BUY AT DIP" signal indicates that the price may attempt a reaction leaning on the channel lower band, but reminds that the trend has not changed, and it may only be a correction of an overshoot (oversold). The Pearson correlation coefficient (r) measures the index-stock relationship; TUPRS (r=0.39), VAKBN (r=0.40) tend to move in the same direction as the index with positive correlation. In stocks like ASELS (r=-0.59), FROTO (r=-0.78), ASTOR (r=-0.93), THYAO (r=-0.87), PGSUS (r=-0.86), MGROS (r=-0.91), strong negative correlation shows these stocks move opposite to the index and do not reduce index risk in portfolio diversification; on the contrary, selling pressure may continue even during index declines.

Diverging Stocks and Structural Differences

TUPRS fits the "structural strength" profile as the only stock in the dataset with both a long-term EMA "BUY" signal, a WT "BUY" signal, and a positive Pearson correlation (r=0.39); its 28.2% return in 60 days confirms this divergence. On the other hand, stocks like ASELS, SAHOL, despite giving a WT "BUY" signal, weaken the reliability of this buy signal with a long-term EMA "SELL/WAIT" and negative Pearson correlation; this situation carries a "false positive" risk.

4. Oscillator and Momentum Readings

RSI and Oversold Region Analysis

According to TradingView oscillator data, 14 stocks have RSI below the 30 level: GUBRF (22.02), MGROS (25.21), SASA (26.22), TOASO (26.93), EREGL (27.25), AEFES (27.21), PGSUS (28.75), TRALT (28.60), TTKOM (28.48), SISE (28.91), TRMET (29.30), KRDMD (29.29), THYAO (31.19), TCELL (31.51). These levels fall into the "oversold" definition in classic technical analysis; however, ADX values (GUBRF 49.4, MGROS 47.5, THYAO 45.4, FROTO 42.7, PGSUS 43.5) hovering above 25 prove the trend is strong and that RSI can remain below 30 for a long time. Therefore, RSI below 30 should be read not as a "buying opportunity" but as a "trend continuation strength" indicator.

MACD, Stochastic and CCI Alignment

The MACD histogram is in negative territory for almost all stocks; the deepest negatives are in GUBRF (-34.14), ASTOR (-27.89), MGROS (-24.89), FROTO (-2.96), TOASO (-13.71). Stochastic %K (StochK) values are also generally below 20 (ENKAI 16.77, PETKM 11.73, ASTOR 9.31, TRMET 6.13, SISE 15.19, TRALT 11.02, TTKOM 14.81, TOASO 10.17, MGROS 7.36, FROTO 17.14, KRDMD 5.31, PGSUS 15.65, EREGL 1.03, AEFES 13.90, SASA 12.93, GUBRF 1.87); this confirms momentum is downward. CCI (Commodity Channel Index) values below -100 (most stocks between -150 and -350) show price is far below its average level and a strong downtrend prevails; EREGL's -347.72 CCI value is the most extreme reading in the dataset.

Trend Strength Differentiation with ADX

Stocks with ADX above 25 (GUBRF 49.4, MGROS 47.5, THYAO 45.4, PGSUS 43.5, FROTO 42.7, ENKAI 41.5, TRALT 40.9, ASTOR 38.0, KCHOL 35.9, SISE 35.4, SASA 35.3, ASELS 33.9, TOASO 33.5, TUPRS 33.4, AKBNK 33.3, SAHOL 36.2) are in a strong trend (up or down); taking oscillator-based counter-trend positions in these stocks is risky. Stocks with ADX below 25 (VAKBN 20.3, YKBNK 17.4, ISCTR 18.7, GARAN 19.6, TAVHL 14.3, PETKM 14.2, KRDMD 16.7, EREGL 16.1, BIMAS 26.5) are in a weak trend or sideways movement; in this group oscillators can give more reliable reversal signals but volume confirmation is essential.

5. Risk Map and Scenarios

Base Scenario: Sideways/Low Volume Pullback

XU030 may continue to trade in a narrow band between 13,800 - 14,000; the index, heavy on banking and holdings, will need a macro trigger (interest rate cut signal, clear downtrend in inflation, current account improvement) to break upward from these levels. If USD/TRY trades in the 49.50 - 49.80 band, the index's slight TL-based appreciation may limit its USD-based performance. In this scenario, while strongly trending stocks like TUPRS outperform, banking and metal stocks may drag the index down.

Optimistic Scenario: Technical Correction and Short-Term Recovery

If XU030 breaks the 14,000 psychological resistance with volume and targets 14,200 levels, a technical "bounce" (reaction) may be seen in stocks in the oversold region (EREGL, GUBRF, MGROS, THYAO, SASA). For this move, USD/TRY must fall below 49.50, Brent crude must hold above 110 USD, and VIX must pull below 18. Under this condition, ENKAI, FROTO, ASTOR giving WT "BUY AT DIP" signal may react first; however, for a trend reversal, MACD must cross above the zero line and the weekly close must stay above the regression channel middle band (approximately 13,950-14,000).

Pessimistic Scenario: Break of Index Support and Sell Wave

If XU030 breaks the 13,800 level (below previous close 13,874.24) on a daily close basis, a risk of deepening toward the 13,500 - 13,600 band (around the 60-day moving average) arises. In this scenario, "STRONG SELL" signals in banking stocks (VAKBN, ISCTR, AKBNK, YKBNK, GARAN) may play a role in pushing the index down. If USD/TRY tests the 50.00 level, foreign selling may accelerate. The ADX strong downtrend in metal (EREGL, KRDMD), chemical (GUBRF, SASA) and Migros (MGROS) stocks may accelerate in this scenario.

Divergence Strategies and Position Management

The negativity of the current portfolio performance (%-14.87) against benchmarks shows that position sizes should be reduced according to risk tolerance and cash ratio increased. For new entries, a "wait for confirmation" strategy (MACD crossover + WT BUY + volume increase) should be applied; "bottom fishing" entries (RSI below 30, CCI below -200) should only be done in trial sizes with tight stop-loss (e.g., 3-5% below entry). A Tüpraş (TUPRS) and selected holding (SAHOL - only if long-term EMA BUY comes) weighted, position-reducing approach in banking and metal is recommended.
