This guide explains the subject in a clear, comparable framework. Prices and conditions change over time; verify current sources before acting.

01

The index is not the whole market

The BIST 100 is a weighted basket, so a few large constituents can move it while most shares travel the other way. Read advances versus declines and turnover alongside the headline percentage.

02

Find the sector leadership

Banks react to rates and regulation, exporters to FX and external demand, airlines to energy costs, and industrials to input prices. Whether a move is broad or led by one sector provides context about its durability.

03

Nominal, currency and real views

A rise in lira terms may look different in dollars or after inflation. The nominal move can describe a day, but medium-term analysis should separate currency, dividends and inflation.

04

Verify flows and headlines

Foreign ownership data, fund flows, credit conditions, company news and disclosures can affect pricing. Ownership statistics may not match the timing of an intraday move, so state the reporting period and publication time.
