Sharp Decline in BIST 100 Drives Margin Calls to 3-Month High

XU100 fell 5.54% daily to 13,122.58, with RSI14 at 17.9, in oversold territory. MACD is negative and below the signal line, momentum is weak. Margin calls rising to a 3-month peak could increase forced selling and sustain downward pressure in the short term. However, oversold conditions may lead to rebound buying; nevertheless, the news flow indicates continued selling pressure. The 1-3 day outlook is downward, confidence 0.7.

AKBNK declined 6.25% to 65.2 amid a sharp drop in the BIST 100, with its RSI at 26.4 approaching oversold territory. Margin calls rising to a three-month high suggest that selling pressure may persist in the short term. MACD being below its signal line and in negative territory also confirms downward momentum. However, oversold conditions and possible bargain hunting could slow the decline. Nevertheless, the 1-3 day outlook is skewed to the downside as margin calls may create liquidity pressure.

ASELS shares declined 4.51% in the last 24 hours to 360 TL, with RSI14 at 28.4 approaching oversold territory. MACD is negative and below the signal line, and the price is trading below its 20 and 50-day moving averages, indicating a weak short-term outlook. The news headline notes that the sharp decline in the BIST 100 has pushed margin calls to a 3-month high; such margin call pressure typically increases selling pressure and raises downside risk in the short term. However, given that RSI is near oversold territory and some of the decline may already be priced in, rebound buying could emerge. Nevertheless, the overall outlook is bearish for the next 1-3 days.

The sharp decline in the BIST 100 and margin calls reaching a 3-month high indicate a decrease in overall market risk appetite and increased forced selling pressure. Although ATEN stock has risen 7.6% in the last 24 hours, this rise is not supported by an RSI approaching overbought territory (61) and a negative MACD signal. Margin calls often trigger additional selling in the short term, creating downward pressure on the stock. However, the stock trading above its SMA20 and SMA50 indicates that the medium-term trend is still positive. Therefore, I assess that short-term downside risk has increased, but the decline may be limited.
