Abstract: If $ c > 1$ there are points $ T(\omega)$ such that the piece of a Brownian path $ B,X(t) = B(T + t) - B(T)$, lies within the square root boundaries $ \pm c\sqrt t $. We study probabilistic and sample path properties of $ X$. In particular, we show that $ X$ is an inhomogeneous Markov process satisfying a certain stochastic differential equation, and we analyze the local behaviour of its local time at zero.
