Çeşitli Endeks Fiyatlarının, Ayı ve Boğa Piyasası Dönemlerindeki Birlikte Hareketleri: Portföy Çeşitlendirmesi Önerileri

Year 2017, Issue: 632, 19 - 26, 01.10.2017

Abstract

Portföy çeşitlendirmesi, dönemine göre düşüşte olan sermaye piyasası durumlarından kaçınmak ve yükselişte olan dönemlerdeki pozitif havadan daha fazla yararlanmak için, yatırımcıların çalışmalarnda önem arz eder. Eğer gerekli portföy çeşitlendirmesi, bir portföyde sağlanmazsa, özellikle endekse bağlı türev araçlar, ayı piyasalarında negatif getiriye sebep olabilirler. Bununla birlikte, eğer portföy yapısı yeteri kadar iyi oluşturulmamışsa, boğa piyasası dönemlerindeki fiyat yükselişi trendinden yeterince yararlanılamayabilir. Bu yüzden, bu çalışmada, uluslararası portföy çeşitlendirmesinin getirilerinden faydalanabilmek için, belirli hisse senedi piyasası endeksleri, temel bileşenler analizi kullanılarak, üç farklı dönemde incelenmiş ve bu ampirik çalışmanın ardından çeşitli portföy çeşitlendirmesi önerilerinde bulunulmuştur. Bu üç dönem sırasıyla, 2008 yılı mortgage krizini içeren ayı piyasası, kriz sonrası dönemdeki boğa piyasası ve büyük para arzı döneminin sonu kabul edilen göreceli boğa piyasasıdır

Co-Movements of Various Indices’ Prices in Bear and Bull Periods: Portfolio Diversification Implications

Year 2017, Issue: 632, 19 - 26, 01.10.2017

Abstract

Portfolio diversification is investors’ crucial action to avoid negative market conditions or to gain more benefits from positive market conditions. Especially derivative instruments clung to various indices may cause negative returns during bear periods if required diversification is not provided on portfolio, and on the other hand, these instruments may cause to inadequately utilize from bull periods if the structure of a portfolio is not established well. Hence, in this study, to utilize the benefits from international portfolio diversification, certain international stock markets co-movements are investigated during three periods by using principal component analysis, and various portfolio diversification implications are generated after this empirical study. These periods are defined respectively a bear period which includes mortgage crises in 2008, a bull period as second period representing after the mortgage crises, a relatively bull period as third period representing the end of huge money supply to the market.
