Query: Decision-Making, Sub-Additive Recursive "Matching" Noise And Biases In
  Risk-Weighted Stock/Bond Index Calculation Methods In Incomplete Markets With
  Partially Observable Multi-Attribute Preferences   While Indices, Index tracking funds and ETFs have grown in popularity during
then last ten years, there are many structural problems inherent in Index
calculation methodologies and the legal/economic structure of ETFs. These
problems raise actionable issues of Suitability and fraud under US securities
laws, because most Indices and ETFs are misleading, have substantial tracking
errors and dont reflect what they are supposed to track. This article
contributes to the existing literature by: a) introducing and characterizing
the errors and Biases inherent in risk-adjusted index weighting methods and the
associated adverse effects; b) showing how these biases/effects inherent in
Index calculation methods reduce social welfare, and can form the basis for
harmful arbitrage activities.
