Ποια επενδυτική στρατηγική ασφάλισης λειτουργεί καλύτερα ;
In this master thesis we will state the sense and usefulness of portfolio insurance. We will outline the potential advantages as well as limitations when deciding to implement such strategies. We will take a close look at some well known insurance strategies and how to properly implement them, as well as some basic facts that an investor should know in order to be able to understand how each strategy works. An optimal portfolio will be constructed according to Markowitz Portfolio theory, in which we will separately apply the previously analyzed insurance strategies. This will be accomplished with real data from 01/01/2022 – 16/12/2022, a time period where the stock market experienced a large downward trend. Afterwards, the results from the implementation of each strategy will be evaluated. According to them, we will draw some conclusions as to which strategy secures the value of the portfolio most effectively under similar economic conditions to those of the 2022 market and we will mention some factors, which can affect the effectiveness of these strategies.
