One of the simple way is by creating a group based on values of your field "Number of Shares Of..".
First of all create a calculated field to generate the bins manually. This is how your formula should look like:
INT([Your variable]/[bin])*[bin]
Then, on this calculated field create a group. Select the members that you want to group (34000K+), and then click the Group and name it whatever you want.
Finally, you can use this created group in the column shelf.
