ZYXI Short Interest Chart

The below chart depicts the ZYXI short interest history in graphical format, with the X-axis representing the historical ZYXI short interest date and the Y-axis showing the total amount of shares short as of each measurement date (ZYXI short interest measured twice monthly). The ZYXI short interest chart is interactive, meaning you can hover over any given data point to see the data values as well as days to cover information. Also refer to the ZYXI short interest data table below the chart itself. Open the ZYXI page at The Online Investor »

ZYXI Short Interest Data Table

This ZYXI short interest data is presented in table format, where each row represents one ZYXI short interest measurement on the indicated date (listed in the first column). The next column indicates the "days to cover" value which compares ZYXI's recent average trading volume against the total number of ZYXI shares sold short in the aggregate — in other words, take the "ZYXI shares short" column, and divide by the average trading volume, and you get the ZYXI days-to-cover reading. Finally, in the last column we show the change in number of shares of ZYXI that have been sold short, where a positive number means additional ZYXI shares were shorted during the period since the last measurement, while a negative value means that ZYXI shares were covered by short sellers during the period.
