Tracking ability of metal exchange traded funds (etfs)

Tracking ability of metal exchange traded funds (etfs)

Abstract

Exchange Traded Funds (ETFs) são fundos de investimento transaccionados em bolsa que foram criados recentemente e têm vindo a crescer bastante nos últimos anos. Apesar do extenso número de investigações sobre este assunto, existem poucos dedicados ao estudo de Commodity ETFs e à sua aptidão como investimento alternativo em commodities. Assim, de forma a conhecer a sua viabilidade como investimento e a sua capacidade em replicar o benchmark, foi analisado uma amostra de 27 ETFs de metais, transaccionados na NYSE Arca. O foco desta tese é a capacidade de replicação semanal dos ETFs, avaliados através de regressão linear, testes de tracking error e indicadores de análise de performance. Depois, é ainda testado o mispricing potencial, a fim de perceber se os ETFs são transaccionados pelo seu “preço justo”, ou se os seus preços tendem a se desviarem do seu NAV. Os resultados da regressão linear e do tracking error mostram que a maioria dos ETFs têm alfas negativos, contudo são todos estatisticamente não diferentes de zero. Além disso, apresentam correlações fortes e baixos desvios em relação aos seus benchmarks, onde os físicos têm os valores mais baixos. Em relação à performance, não é possível eleger a melhor estratégia, visto terem sido obtidos resultados mistos. Ainda, de acordo com a análise de mispricing a maioria dos ETFs são transaccionados a prémio, onde todos os físicos são transaccionados a um preço superior ao seu NAV.

Exchange Traded Funds (ETFs) are investment funds traded in stock exchanges that have recently been introduced and have been growing significantly over the last few years. Despite the vast number of research studies on this topic, there has been a certain lack of attention directed to Commodity ETFs and their suitability as an alternative investment in commodities. In order to understand their viability as an investment and their capacity in tracking their benchmarks, this study analyzes a sample of 27 metal ETFs, traded on the NYSE Arca. The focus of this thesis is the weekly tracking ability of ETFs, evaluated through a linear regression, tracking error tests and performance analysis indicators. Then, it is also tested the potential mispricing to understand if the ETFs are traded at their “fair prices” or if their price tend to deviate from their net asset values (NAV). The linear regression and the tracking error results show that most ETFs have negative alphas, although not statistically significant. In addition, they also show strong correlations and low deviations from the benchmarks, where the physically-backed have the smallest values. Regarding the performance, it is not possible to elect the better strategy, due to the mixed results obtained. According to the mispricing analysis, most of the ETFs are traded at premium, where all the physically-backed are traded with a price higher than their NAV.
