# How to write below \bullet in Latex [duplicate]

I have to write something under the symbol \bullet in Latex. Is it possible? I'm using the class beamer. Here it is an example of a frame:

\begin{frame}
\begin{itemize}
\item<1-> Products Market\mbox{}\\ \footnotesize{where $p_{i,t}=u_{i,t}$, with $u_{i,t}\sim u[0,2]$}
\vspace{0.5cm}
\item<2-> Credit Market \mbox{} \vspace{0.2cm} \\ \footnotesize{where \hspace{0.1cm} $\bullet_{bank} \xrightarrow{loan} \bullet$}
\vspace{0.5cm}
\item<3-> Interbank Market\mbox{} \vspace{0.08cm} \\ \footnotesize{where \hspace{0.1cm} $\bullet \xrightarrow{loan} \bullet$}
\end{itemize}
\end{frame}


In particular I want to write "bank" under the bullet, whilenow it is only in subscript.

Thanks
