# Locally riskfree asset

A self-financing portfolio h is **locally risk-free** if

dV^{h}(t)=k(t) V^{h}(t)dt,

where k is an adapted process. If h is locally risk-free then k(t) should equal the short rate r(t) for all t in order to avoid arbitrage opportunities.

dV

where k is an adapted process. If h is locally risk-free then k(t) should equal the short rate r(t) for all t in order to avoid arbitrage opportunities.
