In this paper, we investigate the implications of measurement errors in the daily published stock prices on the creation and management of efficient portfolios. Using stochastic simulation techniques and the Markowitz Mean Variance approach in the creation of the weights of the various stocks of...

In this paper, we examine the effects of data collection frequency on the computation of the Consumer Price Index (CPI). Using stochastic simulation techniques, we conclude that the frequency of data collection has a considerable effect on CPI values. Our findings confirm the need for high...

In this paper we test the effects of temporal aggregation (disaggregation) on the efficiency of portfolio construction using the mean variance optimization approach. Using Monte Carlo techniques and empirical data from the Athens Stocks Exchange we confirm that the use of temporally aggregated...
