Index Mutual Fund Replication [PDF]

open access: yes, 2010
This chapter discusses the application of an index tracking technique to mutual fund replication problems. By using a tracking error (TE) minimization method and two tactical rebalancing strategies (i.e. the calendar based strategy and the tolerance triggered strategy), a multiperiod fund tracking model is developed that replicates S&P 500 mutual fund ...

Quantitative analysis of replication-related mutation and selection pressures in bacterial chromosomes and plasmids using generalised GC skew index

open access: yesBMC Genomics, 2009
Background Due to their bi-directional replication machinery starting from a single finite origin, bacterial genomes show characteristic nucleotide compositional bias between the two replichores, which can be visualised through GC skew or (C-G)/(C+G ...

Leveraged funds: robust replication and performance evaluation [PDF]

open access: yes, 2023
Leveraged and inverse exchange-traded funds seek daily returns equal to fixed multiples of indexes’ returns, but the ensuing rebalancing costs create a tension between a high correlation with the index and a low average deviation from the leveraged index’

The cytogenetic effects of black tea and green tea on cultured human lymphocytes

open access: yesBrazilian Archives of Biology and Technology, 2011
In this study, the cytogenetic effects of black tea and green tea were determined in cultured peripheral blood lymphocytes. Results showed that black tea and green tea induced the mitotic and replication indexes and decreased micronuclei.
