5. Conclusions
The paper improves available literature by emphasizing the RiskMetrics performance on Romanian financial
market over the last financial crisis. We used daily financial data starting with January 1st, 2001 until December 31st,
2012 for three indices: BET, BET-C and BET-FI. We start the study with the empirical estimation of the decay
factor through two types of functions: squared error loss function (RiskMetrics’ methodology) and check error loss
function (Gonzalez-Riviera et al. (2007) methodology).
