Unseasoned Security

See: Seasoned Issue. One that is unseasoned...is a new issue. It hasn't had time to trade or set real trading patterns or have Street inspection as to how it trades in a bad market, a good one, or a weird one where a bomb goes off in Moscow instead of Riyadh, and Israel and Qatar play handball together.

Unseasoned. New. Maybe newly IPO'd (and not PO'd). Add a bit of salt if it's bland.
