Invested or not, 500,000 THB should not be a meaningful portion of a quality tourist's net worth.
You'll want to have instant access to liquid cash when you find yourself in a tough spot. Try hitting a local on your motorbike in a Thai part of town and see how gnarly things get without being able to settle things on the spot. The police will be involved before you can even explain them what stocks are. It all goes downhill from there.
Immigration knows this very well. Poverty = trouble. Quality tourism only.
