Purpose This paper aims to identify a possible mismatch between the theory found in academic research and the practices of investment managers in Brazil. Design/methodology/approach The chosen approach is a field survey. This paper considers 78 survey responses from 274 asset management companies. Data obtained are analyzed using independence tests between two variables and multiple regressions. Findings The results show that most Brazilian investment managers have not adopted current best practices recommended by the financial academic literature and that there is a significant gap between academic recommendations and asset management practices. The modern portfolio theory is still more widely used than the post-modern portfolio theory, and quantitative portfolio optimization is less often used than the simple rule of defining a maximum concentration limit for any single asset. Moreover, the results show that the normal distribution is used more than parametrical distributions with asymmetry and kurtosis to estimate value at risk, among other findings. Originality/value This study may be considered a pioneering work in portfolio construction, risk management and performance evaluation in Brazil. Although academia in Brazil and abroad has thoroughly researched portfolio construction, risk management and performance evaluation, little is known about the actual implementation and utilization of this research by Brazilian practitioners.

In The Beginning

The Finnish commercial property market internationalised rapidly in the beginning of the 21st century. According to the portfolio theory and previous research on international property investments, the main motivation factor driving international real estate investments is the possibility to reach diversification benefits. The paper discusses the diversification benefits offered by the Finnish property market in its early years of internationalisation. As international real estate investors in the Finnish property market include investors with both real estate only, as well as mixed‐asset portfolios, the diversification benefits are studied both in terms of a Finnish mixed-asset portfolio, as well as international real estate portfolio. Santruka XXI a. pradžioje Suomijos komercinio nekilnojamojo turto rinkoje sparčiai vyko tarptautiniai procesai. Remiantis portfelio teorija ir ankstesniais tyrimais apie tarptautines investicijas i nekilnojamaji turta, pag rindinis veiksnys, kuris skatina tarptautines nekilnojamojo turto investicijas ‐ tai galimybe gauti diversifi kacijos teikiama nauda. Darbe aptariama, kokia nauda siūle Suomijos nekilnojamojo turto rinka ankstyvaisiais internacionalizacijos metais. Kadangi kai kurie Suomijos nekilnojamojo turto rinkoje veikiantys tarptautiniai nekilnojamojo turto investuotojai užsiima tik nekilnojamuoju turtu, o yra ir tokiu, kurie turi mišraus turto portfelius, diversifi kacijos nauda nagrinejama ir pagal Suomijos mišraus turto portfeli, ir pagal tarptautini nekilnojamojo turto portfeli.
