Large flourishing capitals on a signature

What does it mean when there are large flourishing capitals on a signature?

Large capitals are a sign of good self esteem … until they become overly large. Then they become egotism.

So if the capitals are large, but within a reasonable proportion to the rest of the writing, good self esteem is shown.

If they are gigantic, and way out of proportion to the rest of the signature, then this is someone who is puffing themselves up unrealistically.
