Minute log returns use consecutive same-day closes; the high--low range is $\log(H)-\log(L)$ per one-minute bar; bars exist only for minutes with at least one reported trade. Prices are unadjusted for splits; the pilot is descriptive and imposes no corporate-action screens.31\end{tablenotes}32\end{threeparttable}33\end{adjustbox}34\end{table}
