How does THY diverge from the index in dollars?
An airline earns a large share of its revenue in hard currency. The dollar chart shows whether THY actually separated from the BIST 100 underneath the lira records.
The same day, two numbers
At the 27 Oct 2026 close, THY (THYAO) stood at $5.08 in dollars and ₺253.00 in lira. The BIST 100 on the same close was $224.00 in dollars. A single day's price is not the story; the comparison that matters is the return.
The past year
Over the past year THYAO moved -27.7% in dollars and -14.2% in lira. Over the same stretch the index moved -13.3% in dollars and +2.7% in lira. Both dollar figures use the same rate, so the gap is the company's own performance, not the unit of measure.
Distance from the peak
THYAO's five-year dollar peak was $9.99 on 07 May 2024; the stock is 49.1% below that level. The index's dollar peak was $338.59 on 22 Jul 2024; the index is 33.8% below it. The two distances can be read in the same unit.
Today's summary
