Options specialists on the buy side?

I know my question isn't incredibly well-informed (I'm new) but is there a reason no one seems to be responding? Do I need to refine the question in some way?

Options specialists on the buy side?

<t>"Options specialists on the buy side are most likely to find themselves in a risk management role where portfolio managers use them to help hedge against risk they, the managers, don't like"This was mentioned to me today.

The Phillips Curve (among other things)

<t>QuoteOriginally posted by: Traden4AlphaThe suspicion is mutual. Exaggerating, somewhat, Wall Street sees the economists as Ivory tower egg-heads that couldn't trade their way out of a paper bag. Economists see Wall Street as populated by a motley assortment of shysters and gamblers. At the heart ...
