Consider a random walk on $\mathbb{Z}$ with triangular drift and jumps that are standard normals. That is,
$$
\begin{cases}
RW_{t+1} = RW_t - d + \epsilon_t, \quad t \geq 0,\\
RW_{t-1} = RW_t - d + \epsilon_{t-1}, \quad t \leq 0,
\end{cases}
$$
where $\epsilon_t$ are iid standard normals.

Using Skorohod embedding, we can think of $W_t$ as the values of a Brownian motion with triangular drift at integer time points:
$$
RW_t = B_t - d |t|, \quad \text{for $t \in \mathbb{Z}$}
$$
where $B_t$ is a standard Brownian motion (and equality is in distribution). This tells me that
$$
\max_{t \in \mathbb{Z}} RW_t \leq \max_{t \in \mathbb{R}} (B_t - d|t|)
$$
(in the sense of stochastic domination), and the difference between them is not too large (~max of a Brownian bridge with different endpoints?).

Question: is something similar true for $\arg\max$, the location of the maximum? That is, is it true that
$$
\arg\max_{t \in \mathbb{Z}} RW_t \quad \text{ is not too far from } \quad
\arg\max_{t \in \mathbb{R}} (B_t - d|t|) ?
$$
(Stochastic domination seems unlikely.)

Note that this might have nothing to do with probability -- it might be a question about how continuous the $\arg\max$ functional is.
