Value at Risk - The Square Root Rule

The SRR has come under serious assault from leading researchers focusing on its week theoretical basis: assuming i.i.d. asset returns. I performed an empirical test of the SRR on the 10-day horizon, the maximum horizon allowed by Basel, comparing SRR performance to d
