Deep Analysis

1. Market Summary and Overview

As of Monday, October 12, 2026, 12:28, the BIST 30 (XU030) index is trading at 15.044.55 points, recording a 0.67% loss compared to the previous close, while the BIST 100 (XU100) is down 0.65% at 12.185.97 points. The USD/TRY exchange rate is almost unchanged at 49.33 (+0.03%), while XU030's daily performance in dollar terms, net of the exchange rate effect, is calculated as -0.69%. Although selling pressure dominates the market overall, notable divergences include Vakıfbank (VAKBN) standing out with strong buy signals in the banking sub-sector and TR Anadolu Metal's (TRMET) structural trend remaining intact in Metals & Mining. On the macro front, Türkiye's annual consumer inflation for September 2026 came in at 29.73%, producer inflation (PPI) lagged at 27.38% annually, and the policy rate is held steady at 37.0%; real rates remaining in positive territory constitutes one of the key arguments supporting domestic equity demand, although weakening global risk appetite (VIX 14.84, DXY 102.21) and Brent crude trading around 104.72 USD/barrel keep import cost pressure alive. Portfolio performance has lost 6.77% since the September 6, 2026 start, relatively less than the XU100 (-13.32%) and XU030 (-9.47%) benchmark indices, though the cash-heavy positioning (portfolio 93.234 TL) reflects market neutrality.

Index Structure and Breadth

The 0.67 per cent decline in the XU030 can be explained by the fact that almost all of the index’s weighted shares (THYAO, GARAN, AKBNK, KCHOL, SAHOL) issuing ‘STRONG SELL’ or ‘SELL’ signals; the index’s one-sided downward movement also indicates a weakening of breadth indicators (the number of advancing versus declining shares). The fact that the XU100 fell by a relatively smaller margin than the XU030 (0.65 per cent vs 0.67 per cent) may be a sign that selective buying demand continues in mid- and small-cap shares; however, the fact that only two shares (VAKBN, TRMET) are generating a ‘STRONG BUY’ signal in the technical screening data suggests that market breadth is narrowing.

Effects of Foreign Exchange and Commodities

The fact that the USD/TRY exchange rate has remained stable at 49.33 indicates that, within the framework of the CBRT’s management of its foreign exchange reserves (60.33 billion USD, as at 8 October) and the real effective exchange rate index (105.45, September data), indicating that the exchange rate is being maintained within a controlled band. The rise in the price of gold to 4.216 USD per ounce (+1.43 per cent) and the increase in the price of gold per gram to 6.653 TL can be explained by a combination of the weakening US Dollar Index (DXY 102.21) and falling oil prices (Brent 104.72, WTI 91.85); this situation presents a positive outlook for gold mining and precious metals portfolios, whilst painting a mixed picture for the margins of Tüpraş (TUPRS) and the petrochemical sector (PETKM, ENKAI).

2. Sector-Based Evaluation

Banking: The Leadership Advantage and Selective Differentiation

The banking sector is experiencing a sharp divergence between VAKBN's "STRONG BUY" (short/medium/long EMA: BUY, Wave Trend: BUY, Pearson r: 0.76, Channel 40%) and major banks such as Garanti BBVA (GARAN), Yapı Kredi (YKBNK), Akbank (AKBNK) and İş Bankası (ISCTR) giving "SELL" / "STRONG SELL" signals. While VAKBN's momentum direction is upward with RSI 54.29, MACD +0.21, Stochastic 66.45% and CCI +87.09; AKBNK (RSI 45.50, MACD -0.72, CCI -57.02), ISCTR (RSI 46.88, MACD -0.10, CCI -51.19) and YKBNK (RSI 50.70, MACD 0.00, CCI +17.95) have negative or neutral momentum indicators. This shows that rather than a judgment on the entire sector, stock picking based on asset quality and credit growth (36.32% annual, August data) differentiation is required.

Metals & Mining: Structural Strengthening Under TRMET’s Leadership

TRMET, with its +15.8% return over 60 days, "BUY" overall signal (medium/long EMA: BUY, Wave Trend: BUY, Channel 41%, r: 0.20) and oscillator confirmation (RSI 50.47, MACD -0.94, Stoch 50%, CCI +39, ADX 17.45), is the sector's only "strong" stock. In contrast, Ereğli Demir Çelik (EREGL) gives a technical "SELL" (overall) while giving a "BUY" signal on oscillators (RSI 50.80, MACD -0.31), creating a divergence; Kardemir (KRDMD) remains in the "SELL/NEUTRAL" zone under both methodologies. The critical level for the sector is Chinese demand data and the course of global steel prices; TRMET's 41% position within its regression channel supports the medium-term validity of the trend.

Energy & Petrochemicals: Widespread Weakness

Tüpraş (TUPRS), Petkim (PETKM), Enka Construction (ENKAI) and Astor Energy (ASTOR) are trading on technical ‘SELL’ signals. Whilst TUPRS’s Pearson correlation of 0.80 indicates a strong downtrend (channel 6 per cent, RSI 44.81, CCI -105, ADX 29.78), ASTOR’s performance of -32.5 per cent over 60 days and "BUY ON DIP" Wave Trend signal (channel 28 per cent, r: -0.72) may signal an attempt at a technical rebound; however, with the MACD at -25.76 and the ADX at 36.09, the downtrend remains very strong. Brent crude trading below USD 105 may put pressure on the fundamental valuation models of these shares via refinery crack spreads.

Aviation, Tourism and Transport: Structural Sales Pressure

THYAO, Pegasus (PGSUS) and TAV Airports (TAVHL) are showing ‘STRONG SELL’ signals (THYAO: channel 63 per cent, r: -0.88, RSI 45.22, ADX 30.80; PGSUS: channel 7 per cent, r: -0.82, RSI 33.18, ADX 30.25; TAVHL: channel 36 per cent, r: -0.03, RSI 45.34, ADX 14.05) are the weakest links in the sector. THYAO’s return of -12.6 per cent over 60 days and PGSUS’s performance of -18.8 per cent, combined with expectations of a seasonal slowdown and uncertainty over fuel costs, are driving sellers into the market. TAVHL’s relatively stronger momentum, as indicated by a Stochastic reading of 56.29 per cent, may harbour potential for a short-term rebound due to the operational leverage effect; however, trend filters (EMA alignment: SELL) do not support this scenario.

Retail, Telecoms and Holding Companies: Broad-Based Diversification

BİM (BIMAS) and Migros (MGROS), with "STRONG SELL" signals (MGROS: channel 69%, r: -0.91, RSI 39.52, ADX 35.04), remain under pressure from slowing consumer spending (CPI food subgroup effect, retail sales 10.4% annual July data) and credit cost pressure in a high-interest environment. Turkcell (TCELL) and Türk Telekom (TTKOM), with "STRONG SELL" signals (TCELL: channel 54%, r: -0.69, RSI 45.10, ADX 24.87), are pricing in the risk of ARPU growth remaining below inflation. Koç Holding (KCHOL) and Sabancı Holding (SAHOL), with "STRONG SELL" signals (KCHOL: channel 3%, r: 0.62, RSI 42.83, ADX 28.49; SAHOL: channel 8%, r: 0.06, RSI 39.58, ADX 37.00), reflect the weakening of bank and energy portfolios within the holding structure.

Property and Other Items

Emlak Konut GYO (EKGYO) gives a technical "NEUTRAL" signal (short BUY, medium/long WAIT, channel 44%, r: 0.40) while receiving "BUY" confirmation on oscillators (RSI 52.19, Stoch 76%, CCI +83, ADX 13.59); this supports a short-term relative strength scenario driven by the inflation-indexed structure of rental income and low leverage. Anadolu Efes (AEFES) is in horizontal consolidation with technical "SELL" and oscillator "NEUTRAL" (RSI 50.16, ADX 24.36); Şişecam (SISE) and Aselsan (ASELS) continue in strong downtrends (SISE: channel 42%, r: -0.59, ADX 23.84; ASELS: channel 18%, r: -0.01, ADX 26.36).

3. Technical Visual Analysis

EMA Configurations and Trend Classification

The ‘short/medium/long’ EMA status in the scan data was used as the primary filter to classify the direction and strength of the trend. VAKBN By showing a ‘BUY’ pattern across all three levels (assuming EMA5 > EMA20 > EMA50), it indicates a strong upward trend. TRMET With a ‘BUY’ recommendation for the medium and long term and a ‘WAIT’ recommendation for the short term, this pattern points to a scenario of trend continuation following a pullback. In banking-heavy sectors GARAN, YKBNK, AKBNK, ISCTR and in holding companies KCHOL, SAHOL Almost all of the index-weighted shares show a ‘SELL’ pattern (short/medium/long); this technically confirms that the centre of gravity of the XU030 is shifting downwards. EKGYO By issuing a ‘BUY’ signal only in the short term, it indicates that the long-term trend has not yet been confirmed.

Wave Trend (WT) and Reversal Signals

The Wave Trend oscillator is an effective tool for identifying overbought and oversold levels and reversals within a trend. VAKBN andTRMET " Whilst the ‘AL’ signal indicates momentum in line with the trend direction; EKGYO, PETKM, GUBRF, TRALT, ENKAI, FROTO, SISE, SASA, ASTOR, EREGL, AEFES " Although it is giving an ‘AL’ signal, it is at odds with the general trend filters (EMA sequence: SELL/WAIT) (bearish divergence / risk of a false buy signal). ASTOR Although the “BUY ON DIP” signal was triggered by the price approaching the lower band of the channel (28 per cent) and the WT rebounding from the oversold zone, it should not be forgotten that, with a Pearson r of -0.72 and an ADX of 36.09, the trend remains very strongly bearish. TUPRS, BIMAS, KRDMD, GARAN, KCHOL, YKBNK, AKBNK, ISCTR, SAHOL, TOASO, ASELS, TAVHL, TTKOM, TCELL, PGSUS, THYAO, MGROS " It confirms the trend direction with a ‘SAT’ signal.

Regression Channel Positions and Pearson Correlation (r)

The percentage position within the regression channel (0% = lower band, 100% = upper band) shows the price's relative location against the trend.VAKBN 40%, TRMET 41%, EKGYO 44% trade above the average band, indicating a trend-supported structure. In contrast,TUPRS 6%, BIMAS -2%, KCHOL 3%, SAHOL 8%, TOASO 26%, PGSUS 7% trade in the lower quartile of the channels or below the lower band (negative value); for these stocks, "bottom fishing" attempts are unconditionally risky unless the channel is retested and the EMA alignment turns to "BUY". The Pearsonr coefficient gives the direction and strength of the relationship between price and time (linear regression).VAKBN r: 0.76 ( strong positive trend),TUPRS r: 0.80 ( strong negative trend - consistent with the 6% channel position),THYAO r: -0.88, MGROS r: -0.91, PGSUS r: -0.82, SISE r: -0.59, SASA r: -0.62, ASTOR r: -0.72, EREGL r: -0.74 values indicate that these stocks are in strong negative correlation with their time series (i.e., in a continuous downtrend). EREGL for the channel is 78% (near the upper band) but r: -0.74 (strong negative trend) contradiction shows that the price has fallen from past highs and pulled back to the upper part of the channel, yet the trend is still downward; this is a "lower high" formation.

4. Oscillator and Momentum Readings

RSI (14) Dynamics

When the RSI 50 level is taken as the trend demarcation line; VAKBN (54.29), TRMET (50.47), EKGYO (52.19), EREGL (50.80), YKBNK (50.70), AEFES (50.16), GARAN (50.02) are trading above or very close to the 50 level, indicating that at least short-term momentum is not negative. KRDMD (48.13), PETKM (47.88) are just below 50. All remaining stocks (especially PGSUS 33.18, SASA 35.85, ASTOR 36.24, MGROS 39.52, SAHOL 39.58, BIMAS 40.78, FROTO 41.35) are at or below the 40-45 band; although these levels fall under the "oversold" definition, the high ADX values (trend strength) (e.g., SAHOL 37.0, MGROS 35.0, ASTOR 36.0) indicate that the RSI can remain in these zones for a long time and that signaling a "bottom" may be premature.

MACD (Moving Average Convergence Divergence)

The MACD histogram and line measure the acceleration of momentum. VAKBN (+0.21) stands out as the only stock with a positive MACD value. EKGYO (0.00), YKBNK (0.00), AEFES (-0.20), GARAN (-0.49), KRDMD (-0.30), PETKM (-0.30) are moving in a narrow band around the zero line, reflecting trend uncertainty. AKBNK (-0.72), TUPRS (-1.31), ENKAI (-1.27), FROTO (-1.29), SISE (-0.88), KCHOL (-1.57), GUBRF (-13.84), ASTOR (-25.76), MGROS (-12.40), ASELS (-7.62) stocks with deeply negative MACD values show that sellers are in control and that every rebound will be seen as a selling opportunity.

Stochastic%K,EKGYO (76.29%), VAKBN (66.45%), AEFES (55.90%), TAVHL (56.29%), TCELL (52.96%), TRMET (50.08%) at levels; EKGYO andVAKBN ( except for VAKBN's approach to the upper band, the others are in the neutral zone. PGSUS (7.38%), MGROS (15.73%), BIMAS (13.73%), FROTO (16.30%), KCHOL (19.54%), THYAO (20.27%), TOASO (27.90%), SASA (24.85%), ISCTR (35.50%), ENKAI (31.84%), SISE (28.62%), ASELS (29.31%), TTKOM (25.51%), SAHOL (24.97%) % are in the oversold zone, trading below 20 or around 30%; however, as noted above, strong ADX values remind us that these signals may be "sell continuation" (trend following) signals rather than "buy" signals. In CCI (20) values, VAKBN (+87.09), EKGYO (+82.96) + are approaching the 100 level, creating short-term overbought risk (possibility of a pullback); SAHOL (-159.77), PGSUS (-130.86), KCHOL (-121.30), BIMAS (-119.45), TUPRS (-105.30), ASELS (-99.20), MGROS (-82.15), TRALT (-77.47), TOASO (-77.37), FROTO (-69.67), TTKOM (-64.42), ENKAI (-63.00), ASTOR (-63.17), SISE (-52.64), ISCTR (-51.19), SASA (-57.88), AKBNK (-57.02) stocks such as these have fallen below -100, confirming strong downward momentum.

ADX (Average Directional Index) Trend Strength

With the rule that ADX above 25 indicates "trend exists" and below 25 indicates "no trend/flat"; SAHOL (37.0), ASTOR (36.0), GUBRF (35.0), MGROS (35.0), TUPRS (29.78), THYAO (30.80), PGSUS (30.25), ENKAI (30.30), SISE (23.84 - borderline), ASELS (26.36), AKBNK (26.03), FROTO (26.48), SASA (26.81), KCHOL (28.49), TCELL (24.87 - borderline), TRALT (30.69) stocks are in a strong trend (mostly downward). VAKBN (12.72), TRMET (17.45), EKGYO (13.59), KRDMD (13.43), YKBNK (18.84), GARAN (23.60), AEFES (24.36), PETKM (11.70), TOASO (17.33), TTKOM (13.39) are below ADX 25; in these stocks, the trend is weak or in the formation stage. For VAKBN and TRMET, this indicates that the trend is still in its early stages or momentum is still being built; for stocks with SELL signals (GARAN, YKBNK, PETKM, etc.), it indicates that the trend may weaken and enter a horizontal consolidation (or that the strong downtrend is not confirmed by ADX, and price action is already sufficient).

5. Risk Map and Scenarios

Base Scenario (Baseline Scenario): Selective Distribution and Index Flattening

XU030 continues to trade in the 15.000 - 15.200 band. While strong-trend stocks like VAKBN and TRMET support the lower end of the index, THYAO, PGSUS, Banks (GARAN, AKBNK, ISCTR, YKBNK), Holdings (KCHOL, SAHOL), and Retail (BIMAS, MGROS) pressure the upper end with selling pressure. USD/TRY remains in the 49.00 - 49.50 band. With inflation data (September 29.73%) behind us and the TCMB policy rate held constant at 37%, the search for real returns may direct flows into equities, but this flow will focus only on "quality" and "trending" stocks (VAKBN, TRMET, possibly EKGYO). Invalidation Condition: If XU030 permanently breaks below 14,900 (on a daily closing basis) or permanently surpasses 15,350.

Optimistic Scenario: Technical Reversal with Banking Leadership

VAKBN's strong buying momentum (EMA alignment, WT, MACD+, RSI>50) pulls its sector peers (especially YKBNK oscillator giving BUY signal). XU030 breaks the 15.350 resistance (above the previous close of 15.145) with volume. If USD/TRY falls below 49.00, imported cost pressure decreases, and a technical rebound (oversold bounce) begins for TUPRS/PETKM/ENKAI. TRMET tests the 140 TRY resistance.Concrete Condition: If XU030 holds above 15.250 on a daily close and VAKBN breaks the 35.50 TRY resistance with volume.

Bearish Scenario: Global Risk-Off and Bank Selling

In the scenario where US 10-year Treasury yields rise (in the data set 5Y 5.02%, 30Y 5.60%), DXY moves above 103, and Brent trades above 110 USD; foreign portfolio outflows (portfolio performance already worse than the index) accelerate. In bank stocks (AKBNK, ISCTR, GARAN), "STRONG SELL" signals (EMA alignment, MACD-, deeply negative CCI) push prices below their 60-day averages (AKBNK 60d +2.3% but trend SELL; ISCTR 60d -3.3%). XU030 tests the 14.800 - 14.500 band.Concrete Condition: If XU030 breaks below 14.900 on a daily close and VAKBN falls below 33.50 TRY (if short-term EMA support breaks).

Diversification Strategy (Stock-Picking Focused)

While the index direction is uncertain (XU030 sideways without ADX equivalents), alpha generation is only possible through stock-specific selection.Long Position Candidates: VAKBN (trend confirmation), TRMET (momentum continuation).Short-Term Rebound (Counter-trend) Candidates (Risky): EKGYO (oscillator BUY, technical NEUTRAL), ASTOR (WT BUY at bottom, channel 28% - but trend VERY STRONG DOWN), EREGL (Oscillator BUY, Technical SELL - divergence).Definite Avoids: Stocks with ADX > 30, deeply negative MACD, CCI < -100, EMA alignment SELL (THYAO, PGSUS, MGROS, SAHOL, KCHOL, ASELS, FROTO, TUPRS, SISE, SASA, TTKOM, TCELL, TOASO). Stop-loss levels must definitely be defined as the lower band of the regression channel or the last bottom point.
