چکیده گسترده
معرفی:
ساختارهای درهم تنیده اقتصادهای امروزی باعث می‌شود تا تغییرات در یک بخش یا یک کشور به سرعت به بخش‌ها یا اقتصاد سایر کشورها گسترش یابد. شواهد تجربی نشان داده‌اند که بازارها از یکدیگر جدا نیستند و حرکت های آن‌ها در یک فضای جدا از یکدیگر صورت نمی ‌گیرد. جنبه‌های زیادی برای سرمایه‌گذاری وجود دارد که رایج‌ترین آن­ها سرمایه‌گذاری در صندوق‌های مشترک، صندوق تأمین عمومی، طلا و املاک و مستغلات است. قیمت سهام در بازار تعیین می­شود، جایی که عرضه فروشنده با تقاضای خریدار پاسخ می­دهد. ادبیات اقتصادی و مالی نشان می دهد که نوسانات ناشی از مسائل سیاسی بین­المللی (ارتباطات دولتی، بازار کار، جهانی شدن و کاهش رشد) همراه با مسائل مالی (اهرم، انگیزه­های ریسک بخش مالی و پولی) می­تواند کشورها دیگر و به ویژه شرکای سیاسی و تجاری را تحت تاثیر قرار دهد. بازار مالی نقش مهمی در جمع­آوری منابع مالی و به کارگیری آن­ها در پروژه های مختلف سرمایه­گذاری ایفا می­کند؛ زیرا مکانی است که تمام معاملات سرمایه به منظور سرمایه­گذاری یا تامین مالی در قالب مشارکت یا وام برای اوراق بهادار بلندمدت انجام می شود. از این­رو، برای این­که بازارهای مالی نقش اقتصادی مؤثری در ادغام پس‌اندازهای مختلف داشته باشند، باید اطلاعات مربوطه شرکت‌ها در دسترس باشد و دائماً در قیمت سهام آنها منعکس شود. عوامل و دلایل زیادی بر شاخص قیمت بازار سهام در کشورهای مختلف تاثیرگذار هستند. با وجود آن­که فاکتورهای موثر بر شاخص قیمت بازار سهام عمدتاً از یک رفتار نامتقارن و غیرخطی پیروی می­کند، عمده روش ­هایی که به بررسی این رابطه پرداخته­اند، خطی بوده است. این روش­ها نمی­تواند گویای برازش کاملی از مدل مورد بررسی باشد. مطالعات مختلف نشان داده است که رفتار قیمت سهام و به تبع آن عوامل موثر بر شاخص قیمت نیز عمدتاً رفتاری غیر خطی یا نامتقارن دارند که در بیشتر مطالعاتی که به بررسی عوامل موثر بر شاخص قیمت بازار سهام می ­پردازند، نادیده گرفته شده است.
 
متدولوژی:
در این مطالعه از رویکرد پس از وقوع و از داده های ثانویه استفاده خواهد شد. روش گردآوری داده های مطالعه نیز کتابخانه ای است. برای تجزیه و تحلیل داده ها نیز از رویکرد رگرسیون چندکی استفاده خواهد شد.
 
یافته­ها:
یافته­ های این مطالعه نشان داد که تاثیر تورم، نرخ ارز، نقدینگی، تولید ناخالص داخلی بر شاخص قیمت بازار سهام مثبت و معنی­دار بوده است. اثر تجارت خارجی بر شاخص قیمت بازار سهام نیز رد سطح 90 درصد معنی­دار بوده است. براساس سایر نتایج این مطالعه نیز اثر متغیرهای نرخ ارز و نرخ تورم بر شاخص قیمت بازار سهام نامتقارن بوده است. اثر متغیر تولید ناخالص داخلی، تقدینگی و تجارت خارجی نیز متقارن بوده است.
 
نتیجه:
این نتایج گویای این موضوع است که قیمت­ها به تنهایی نمی­توانند تمامی اطلاعات شاخص قیمت بازار سهام در این کشورها را توضیح دهند و متغیرهای کلان اقتصادی نیز نقشی موثر و تاثیرگذار بر شاخص قیمت بازار سهام رد این کشورهای دارند.

EXTENDED ABSTRACT
INTRODUCTION
The intertwined structures of today's economies make changes in a sector or a country quickly spread to the sectors or economies of other countries. Empirical evidence has shown that the markets are not separate from each other and their movements do not take place in a separate space from each other. There are many aspects of investing, the most common of which are investing in mutual funds, mutual funds, gold and real estate. Stock prices are determined in the market, where seller's supply meets buyer's demand. The economic and financial literature shows that fluctuations caused by international political issues (government relations, labor market, globalization and growth slowdown) along with financial issues (leverage, financial and monetary sector risk incentives) can affect other countries and especially to influence political and business partners. The financial market plays an important role in collecting financial resources and using them in various investment projects; Because it is a place where all capital transactions are done for the purpose of investment or financing in the form of partnership or loan for long term securities. Hence, for financial markets to play an effective economic role in pooling different savings, the relevant information of companies should be available and constantly reflected in their stock prices. Many factors and reasons affect the stock market price index in different countries. Despite the fact that the factors affecting the stock market price index mainly follow an asymmetric and non-linear behavior, most of the methods that have investigated this relationship have been linear. These methods cannot be indicative of a complete fit of the investigated model. Various studies have shown that the stock price behavior and consequently the influencing factors on the price index are mostly non-linear or asymmetric, which has been ignored in most of the studies that investigate the influencing factors on the stock market price index.
 
METHODOLOGY
In this study, the post-event approach and secondary data will be used. The method of collecting study data is library. Quantitative regression approach will be used for data analysis.
 
FINDINGS
The findings of this study showed that the impact of inflation, exchange rate, liquidity, gross domestic product on stock market price index was positive and significant. The effect of foreign trade on the stock market price index has also been significant at the level of 90%. Based on other results of this study, the effect of exchange rate and inflation rate variables on the stock market price index is asymmetric. The variable effect of GDP, competitiveness and foreign trade has also been symmetrical.
 
CONCLUSION
These results show that the prices alone cannot explain all the information of the stock market price index in these countries and macroeconomic variables also have an effective and influential role on the stock market price index of these countries.
