This paper collects three different time-spans data (i.e. daily, weekly and monthly) between Jan. 2003 and Nov. 2013 with a total of 11 year span, and adopts the ordinary least squares regression and quantile regression proposed by Koenker and Bassett (1978) so as to analyze the impacts to gold price trends by oil prices, Dollar indices and S&P500. The empirical findings reveal that the impacts to gold investment returns by S&P500 and Dollar indices are significantly negative whereas impacts to gold investment return by oil prices are significantly positive. That is, scenarios like stock price with downward trending performance, weak Dollar performance as well as high oil price are the most important factors to push the gold trending upward. By the same token, it also signifies that gold is a kind of equity asset portfolio hedging and anti-inflation asset tools. Other than these, by information collected from three different time spans as well as the slope-equality test findings from quantile regression, this study can then provide useful information and serve as references to gold investors who are in the pursuit for daily, weekly and monthly investment returns.
