تأثیر سیستماتیک صرف ارزش در توضیح بازده سهام (فاما و فرنچ، 1992 و 1993) مدت طولانی است که ادبیات مالی و اقتصاد را به کنکاش واداشته است. در حالی که مطالعات اخیر (پتکوا و ژانگ (2005) و چوی (2013)) شواهدی از داده ‏های آمریکا برای رفتار متفاوت شرکت‏ های رشدی و ارزشی نشان می‏ دهند، اما دلایل و منابع این رفتار متفاوت را نشان نمی‏ دهند. علاوه بر این، مشخص نیست که آیا چنین اختلافاتی همچنان در بازارهای سرمایه کشورهای دیگر وجود دارد یا خیر. لذا در این پژوهش ریسک اهرمی و ریسک تجاری (هر دو بر مبنای بتای شرطی) سهام رشدی و ارزشی با استفاده از تکنیک‏ های پارامتریک و ناپارامتریک برای دورۀ زمانی 1378 تا 1396 در میان شرکت‏ های پذیرفته شده در بورس اوراق بهادار تهران با هم مقایسه شد. در این مطالعه شرایط ثبات و بحران بازار و اقتصاد با استفاده از اندازه و نوسانات صرف ریسک بورس اوراق بهادار تهران مشخص شد. همانند مطالعات قبلی (بعنوان مثال چوی، 2013) نتایج مطالعه نشان داد که بتای شرطی (اهرمی و تجاری) در شرایط ثبات اقتصادی تفاوتی ندارد. از طرف دیگر میان ریسک اهرمی و تجاری سهام رشدی و ارزشی در شرایط بحران اقت...

The size and process of the stock price indices are among the most important factors affecting the decisions of the investors in the financial markets. In order to predict the market, different techniques have been used, the most common of which are regression methods and ARIMA models. However, these models have been unsuccessful in the practical prediction of some series. <br />In the present research, in order to predict the total index of the stock, the Feed Forward Neural Network model with the law of back propagation was used in three networks with different input models, and the results of the model were compared to the result of multi – variable regression models and ARIMA models. <br />The results indicated that the neural network method showed considerably fewer RMSE errors than RMSE errors in other methods, and that in Tehran stock market short – term prediction within a shorter interval is more suitable than long – term prediction within a longer interval.
