underly

Meaning "less than something should be". It's the opposite of "overly".
It's one of those words that you know isn't necessarily proper English, but you still find slipping into your sentences every so often.

I am so underly protective, but I know my girl won't mess around

underlying stock

(FINANCE) a stock whose price movements determine the value of a financial derivative. For example, when a hedge fund manager writes a call option for Citigroup (NYSE:C) at 4.25/share, C is the underlying stock.

"Underlying" can be used to refer to other things besides stocks; for example, commodities, currencies, or bonds.

A put option rises when the spot price of its underlying stock declines.
