stocks, stump, shares, stock, counter for small plants
株 centers on a rooted base or unit: a tree stump, a plant stock, a share of stock, or a counter for plants. The common thread is something that grows from or is counted as a distinct rooted entity.
株 combines 木 (tree) with 朱, which likely contributes the sound and may relate to a red stump or base. The character originally referred to a tree stump or root, and later extended to shares and counters.
A tree 木 with a red 朱 mark on its stump: that stump is the base from which new shoots grow, just like a stock or share.
For シュ, imagine a shoe stuck on a stump: shoe -> シュ, and the stump is the base of the tree.
