Excess volatility and investment trusts

Andrew Adams

    Research output: Working paper

    Abstract

    The variance of returns to investment trust shareholders may be split into three components - variance of net asset value (NAV) returns, variance of discount returns and twice the covariance between NAV returns and discount returns. Using historical data, the relative importance of each of these components is estimated for different return intervals, different periods of observation and different sub-sectors. There is clear evidence of excess volatility of trust share returns compared with NAV returns. Since Big Bang in 1986, there has been a significant ‘double whammy’ effect, meaning that discounts tend to widen when NAVs fall and narrow when NAVs rise. Overall, the results are consistent with the noise trader model.
