چکیده

صندوق­های کالایی یکی از انوع صندوق­های قابل معامله در بورس هستند که دارایی پایه آن­ها به جای سهام، محصولات کشاورزی، انرژی و یا فلزات می­باشند. این صندوق­ها به روش­های مختلفی نظیر نگه­داری فیزیکی کالا، قرارداد آتی کالای منفرد، سبدی از قراردادهای آتی کالاها و یا خریداری سهام کالاهای مختلف، سرمایه­گذاران خود را در مقابل بازار انواع کالاها قرار می­دهند. طی سال­های اخیر، این ابزار مالی با ایجاد مزیت­های فراوان به یکی از گزینه­های مهم سرمایه­گذاری در بین معامله­گران تبدیل شده است. با وجود این تحولات، شواهد کمی در ادبیات فعلی در مورد رفتار معاملاتی سرمایه­گذاران این صندوق­ها گزارش شده است. هدف از این مقاله، بررسی وجود معاملات بازخورد در رفتار معامله­گران صندوق­های کالایی زعفران در ایران می­باشد. به این جهت از داده­های روزانه دو صندوق زعفران موجود در بورس کالای ایران یعنی سحرخیز و نویرا، طی دوره زمانی 14/10/1399 الی 30/08/1401 و مدل معاملات بازخورد سنتانا-وادوانی (1992) استفاده شده است. نتایج حاصل نشان داد که نوسان بازدهی صندوق­های زعفران نسبت به اخبار مثبت و منفی متقارن می­باشد. با وجود بازار رسمی با هم­پوشانی کامل برای معاملات دارایی پایه، معامله­گران صندوق­های زعفران توجهی به انحراف قیمت بین صندوق­ها و خالص ارزش دارایی­ آن­ها ندارند. نتایج حاصل از برآورد مدل معاملات بازخورد نشان داد که علائمی از وجود معاملات بازخورد در هیچ کدام از صندوق­های زعفران دیده نمی­شود و معامله­گران این صندوق­ها توجهی به بازدهی گذشته آن ندارند. به نظر می­رسد بازار این صندوق­ها از کارایی برخوردار می­باشد که این موضوع را می­توان با خاص بودن دارایی پایه زعفران و سرمایه­گذاران این صندوق­ها در ارتباط دانست.

چکیده [English]

Commodity Exchange Traded Funds (ETF) are one type of ETF that underlying assets are agricultural products, energy or metals instead of stocks. These ETFs expose their investors to the market of various commodities in different ways, such as physical commodity, futures of single commodity, futures of baskets commodities, equities with exposures to commodities in various forms. In recent years, this financial instrument has become one of the important investment options among several people by creating many advantages. Despite these developments, scarce evidence exists in the current literature on the feedback trading of ETF investors. The objective of this paper is examination of feedback trading in behavior investors of Saffron ETF in Iran. For this purpose, daily data of two Saffron ETF for January 3, 2021 - Novenber 11, 2022 and Sentana and Wadhwani (1992) model was used. Empirical analysis suggests that volatility of fund return is symmetrical against the news. Despite a formal market with full overlapping for the underlying assets, Saffron ETFs investors do not notice about the difference between ETFs' market prices and their Net Asset Value (NAV). The results of the feedback trading model show that there is no evidence of feedback trading in Saffron ETF. It seems that the market of Saffron ETF is efficient, which can be related to the specificity of the underlying assets and the investors of these ETFs.
