This is completely and definitionally true in the context of trading, but keep this definition on a leash because if you apply it outside a purely financial context it tends to smuggle wealth-weighted objectives into your thinking, and regardless of whether or not you think that's moral you probably want to be aware of it. Example: feeding orphans is zero "value" because they can't pay you but merging the banks into a mega-bank to raise fees and collect bailouts has extreme "value" because it can make a bunch of obscenely rich shareholders even more obscenely rich and they can carve you off a mighty slice.
Due to this mismatch I keep both definitions in my pocket: Wealth Weighted Value for finance, People Weighted Value for more colloquial settings or moral analysis. "Exchange Value" is a good quasi-synonym for WWV if you want something less confrontational.
