What is the meaning of "hold any stock"?

Hi! Would you please explain what is the meaning of “hold any stock”? I did not find
explanation anywhere. Thank you in advance! With kind regards, Oinas.

Without any additional context, I would say it means don’t release any more of that particular item from the place that it is so that it can be sold.

[color=blue]I came here looking for some good news, but I am not surprised that there is none. The phrase in question is an idiom that apparently is not in used in U.K. English.

[color=blue]“hold any stock” is an idiom that is usually used in the negative.
‘I don’t hold any stock in what he says.’ means means that I don’t believe what he says.
The following is a sentence I found online. “Personally I don’t hold any stock in the rumors.”

It is used in UK English, but without a context I did not read it as idiomatic.
Thank you. You are probably right that this definition is what was needed.
