So here is a question:

What is Apple's stock price?

First: Is this a full question, or would we need to add something like: What is Apple's stock price at the moment?

Second: What is the subject and verb of the question? Is the subject "Apple's stock" and the verb price, or is "Apple's stock price" the subject? I'm confused.

  • The verb is "is" (as in "to be"), the subject is "price", "Apple's" and "stock" are modifying "price". Commented Sep 10, 2013 at 0:32

The verb to be is a copula here. With copulae, we usually analyse the first constitutent as the subject, the second one as the subject complement.

  • What = subject

  • is = main verb

  • Apple's stock price = subject complement

Within the noun phrase Apple's stock price, the word price is the head; stock modifies price; and Apple's modifies stock price.

Your "at the moment" is possible, but unnecessary, because it is assumed either way.
