Adam Smith tarafından literatüre kazandırılan ‘Homo Economicus’ kavramı, rasyonel ya da ekonomik birey anlamına gelmekte olup yatırımcıların kendi çıkarlarını maksimize eden kişiler olduğunu ifade etmektedir. 1776 yılında ortaya atılan kavram, 1950’li yıllardan itibaren geleneksel finans teorilerinde savunulmaya devam edilmiş ve yatırımcıların yatırım kararlarında rasyonel davrandığı belirtilmiştir. 1970’li yıllardan sonra ise yatırımcıların yatırım kararlarında birtakım anomali ve hevristikler nedeniyle rasyonel olmadığını savunan davranışsal finans kavramı, son yarım asır içerisinde önem kazanan bir konu haline gelmiştir. Davranışsal finans, yatırımcıların yatırım kararlarında birtakım psikolojik, biyolojik, sosyolojik, demografik ya da dışsal faktörler nedeniyle rasyonel davranamadığını savunmaktadır. Rasyonel davranamama sonucunda da yatırımcıların yatırım kararlarında hatalar yaptığı ifade edilmektedir. Davranışsal finans teorisine göre her birey rasyonel olarak kabul edilmemekte ve yatırımcı psikolojisinin yatırımlarda önemli bir etkiye sahip olduğu belirtilmektedir. Bu çalışmada, hava durumu verilerinin BIST TÜM (XUTUM) Endeksi fiyatlarını etkileyip etkilemediğinin tespiti amaçlanmıştır. Çalışma kapsamında, 05.01.2016-29.07.2022 tarihleri arasında XUTUM Endeksi fiyatları ile kış, ilkbahar, yaz ve sonbahar aylarına ait; bulutluluk süreleri ile maksimum, ortalama ve minimum sıcaklık verileri kullanılmıştır. Elde edilen veriler, Borsa İstanbul’un işlem gördüğü günler kapsamında düzenlenerek örneklem oluşturulmuştur. Çalışmada yöntem olarak ANOVA testi ile Regresyon Analizi kullanılmıştır. Çalışma sonucunda, ilkbahar mevsimindeki bulutluluk süreleri ile maksimum, ortalama, minimum sıcaklıkların ve yaz mevsimi maksimum, ortalama, minimum sıcaklıklarının, XUTUM Endeksi fiyatlarını etkilediği tespit edilmiştir. Elde edilen bulgular genel olarak değerlendirildiğinde, hava sıcaklığı verilerinin XUTUM Endeksi fiyatlarını dolayısıyla yatırımcı kararlarını etkilediği sonuçlarına ulaşılmıştır.

The concept of 'Homo Economicus', which was brought to the literature by Adam Smith, means rational or economic individual and states that investors are people who maximize their own interests. The concept, which was introduced in 1776, has continued to be defended in traditional finance theories since the 1950s and it has been stated that investors act rationally in their investment decisions. Behavioral finance, which was advocated after the 1970s and argued that investors are not rational due to some anomalies and heuristics in their investment decisions, has become an important issue in the last half century. Behavioral finance argues that investors cannot act rationally in their investment decisions due to some psychological, biological, sociological, demographic or external factors. It is stated that as a result of not acting rationally, mistakes are made in the investment decisions of the investors. According to behavioral finance theory, not every individual is considered rational, and it is argued that investor psychology has a significant impact on investments. In this study, it is aimed to determine whether weather data affects BIST ALL Shares Index prices. Within the scope of the study, between 05.01.2016-29.07.2022, BIST ALL Shares Index prices for winter, spring, summer and autumn; cloudy times and maximum, average and minimum temperature data were obtained. The obtained data was organized within the scope of the days when Borsa Istanbul was traded, and a sample was created. ANOVA test and Regression Analysis were used as a method in the study. As a result of the study, it has been determined that the cloudiness periods in the spring, the maximum, average, minimum temperatures and the maximum, average and minimum temperatures of the summer season affect the BIST ALL Shares Index prices. When the findings are evaluated in general, it is concluded that the air temperature data affects the BIST ALL Shares Index prices and thus the investor decisions.
