Özet
Cryptocurrencies,
especially in recent years, have gained popularity as an alternative
investment. In this regard, studies conducted in this field are important for
investors to make rational investment decisions. This study aims to investigate
whether Bitcoin can be used for diversification or hedging in stock markets. In
this context, the relationship between Bitcoin and BIST 100, S&P 500
indices has been examined. The Engle-Granger Cointegration Analysis has been
used to investigate the cointegration relationship, and the FMOLS and DOLS
methods have been used to estimate long-term coefficients. The study period has
been selected as the period from 02.11.2020 to 19.07.2022, during which Bitcoin
had a high trading volume. Additionally, this period has been divided into four
sub-periods, covering both bull and bear periods of Bitcoin. The research
results indicate that no cointegrating relationship could be found between
Bitcoin and BIST 100. However, a relationship has been found between Bitcoin
and S&P 500 during the 1. bull and 2. bear periods. During these periods, a
positive impact of Bitcoin on the S&P 500 has been found. In the study, it has been determined that
there is no cointegration relationship between Bitcoin and the BIST 100 index
for all periods, while for the S&P 500, there is no cointegration
relationship in three out of five periods. These findings provide strong
evidence, especially for BIST 100 investors, that by including Bitcoin in their
portfolios, they can achieve better-diversified portfolios.
