Çalışmada enflasyon, faiz oranı, döviz kuru, sanayi üretim endeksi ve petrol fiyatları faktörlerinin BİST-100 endeksi üzerindeki etkisi çok faktörlü regresyon modeli ile araştırılmış; endeks ile faktörler arasındaki karşılıklı nedensellik ilişkisinin tespitine yönelik Johansen eş bütünleşme testi, vektör hata düzeltme modeli ve Granger nedensellik testi uygulanmıştır. Sonuçta döviz kuru değişkeni BİST-100 üzerinde açıklayıcılığa sahip tek faktör olarak bulunmuştur. Sanayi ve döviz kurunun BİST-100’deki değişimlerin tahmin edilmesinde kullanılabileceği ancak tersinin geçerli olmadığı, BİST-100’ün yalnızca petrol değişkeni için Granger nedenselliğine sahip olduğu görülmüştür.

Anahtar Kelimeler

Makroekonomik faktörler, hisse senedi getirileri, çok faktörlü modeller, eş bütünleşme, vektör oto regresyon, Granger nedensellik

THE EFFECTS OF MACROECONOMIC FACTORS ON STOCK MARKETS: AN APPLICATION IN BORSA ISTANBUL

Öz

In this study, the effects of factors on BIST-100 index that are inflation, interest rate, exchange rate, industrial production index and oil prices are investigated by a multifactor regression model; Johansen co integration test, vector error correction model and Granger causality test are performed in order to determine the mutual causality relation between factors and stock market index. As a result, exchange rate is found as the only factor that explains BIST-100. Industry production index and exchange rate can be used to predict changes in BIST-100 but opposite is not valid; BIST-100 Granger causes only oil price factor

Anahtar Kelimeler

Macroeconomic factors, stock returns, multi factored models, co integration, vector auto regression, Granger causality
