unload shares

Hi forum!

This is my first posting in this forum, and I would appreciate if you help me with the following translation:

When investors unload shares or the market falls, prices can drop rapidly.

My attempt would be:

Cuando los inversionistas se deshacen/se despojan de las acciones o el mercado colapsa, los precios pueden caer rápidamente.

Thanks in advance for your help,

Hola diddy bienvenida, buena traducción.
