چکیده مقاله :
شاخص کل بورس شرکتهای پذیرفته شده در بورس یکی از معیارهای مهم در ارزیابی اقتصاد کلان به شمار می رود. ازجمله عوامل مؤثر بر شاخص قیمت سهام نرخ ارز، قیمت نفت و رشد اقتصادی است. در این پژوهش به بررسی اثر نوسانات نرخ ارز، قیمت نفت خام و نرخ رشد اقتصادی بر شاخص کل بورس اوراق بهادار تهران، طی دوره زمانی 1397 -1388 با استفاده از داده های ماهانه پرداخته شده است. در ادامه برای محاسبه نوسانات نرخ ارز، قیمت نفت و رشد اقتصادی از روش خود رگرسیونی واریانس ناهمسانی شرطی استفاده شده است و سپس از طریق الگوی گشتاور تعمیم یافته مدل برآورد گردیده است. نتایج حاصل از برآورد مدل نشان داد که نوسانات شاخص کل بورس اوراق بهادار تهران تحت تأثیر نوسانات نرخ ارز، قیمت نقت خام و رشد اقتصادی قرار می گیرد و از بین آنها شاخص کل یک دوره قبل و نرخ ارز بیشترین تأثیر را بر شاخص کل بورس اوراق بهادار میگذارد.Investigating the Mechanism of Fluctuation Exchange Rate, Oil Price and Economic Growth on the Tehran Securities Exchange Nasser SeifollahiHamed SeifollahiThe overall stock market index of listed companies is one of the important criteria in assessing macroeconomics. Among the factors affecting the stock price index are the exchange rate, oil prices and economic growth. In this study, the effect of exchange rate fluctuations, crude oil price and economic growth rate on the total index of Tehran Stock Exchange, during the period of 2009-2018 using monthly data has been studied. Then, to calculate exchange rate fluctuations, oil prices and economic growth, the regression method of conditional variance variance was used and then it was estimated through the generalized model torque model. The results of the model estimate showed that the fluctuations of the total index of Tehran Stock Exchange are affected by exchange rate fluctuations, crude price and economic growth, and among them the total index of a previous period and the exchange rate have a greater impact on the overall stock market index.
