TY - JOUR T1 - Negative Beta Equity Securities as Insurance JF - The Journal of Wealth Management SP - 69 LP - 73 DO - 10.3905/jwm.2021.1.156 VL - 24 IS - 4 AU - Tom Arnold AU - Terry D.

However, equity securities with negative betas are relatively rare and simply determining that an equity security exhibits a negative beta is not enough for determining if the negative beta equity security will perform in the desired manner. Negative betas can, at times, be attributed to causes that diminish those securities' usefulness as insurance. Some of these causes are explored in this article. ER -
