Reinhold Hafner, Martin Wallmeier
Volatility has evolved as an attractive new asset class of its own. The most common instruments for trading volatility are variance swaps. Mean returns of DAX and ESX variance swaps over the time period of 1995 to 2004 are strongly negative, and only part of the negative premium can be explained by the negative correlation of variance swap returns with stock market indices.

In this exploratory study, we develop a two-ste...... hiện toàn bộ
