Why it moves the price

Guidance is about the future, and valuation is entirely about the future. Raised guidance moves every forward estimate at once.

What separates a good call from a naive one

This is typically the single most powerful scheduled catalyst — stronger than the reported quarter itself. Check the quality: raising on genuine demand is very different from raising because of a buyback lowering the share count or a one-time tax benefit.
