ABSTRACT This paper characterizes the complete class of time‐invariant portfolio insurance strategies and derives the corresponding value functions that relate the wealth accumulated under the strategy to the value of the underlying insured portfolio. Time‐invariant strategies are shown to correspond to the long‐run policies for a broad class of portfolio insurance payoff functions.

ABSTRACT In this paper, we examine the stock price reactions to announcements of new security offerings by Real Estate Investment Trusts (REITs). REITs offer a unique setting in which to study these events because they do not pay taxes at the firm level. Theory suggests that the net tax gain to corporate borrowing is unambiguously negative for a REIT. Contrary to some recent studies, however, we find a positive stock price reaction to debt offerings, while the negative equity‐issuance effect is preserved. Further empirical evidence lends support to signalling as the explanation for the positive significant debt‐issuance effect.
