Underlying instrument
Both commodities and financial instruments (shares, bonds, currencies,
indices, etc.) can underlie derivatives contracts.
Some underlying instruments, such as commodities, shares, bonds, or
currencies, can be physically delivered, while others - so-called notional
underlying instruments - cannot. Notional underlying instruments are
standardized and assigned certain attributes so that they can serve as
benchmarks. For example, the Bund future is a contract on a notional
instrument which represents a classic Federal Government Bond, with an
interest rate of six percent and a maturity of ten years. Indices are another
type of notional underlying instrument. An option on DAX® is a contract on the
stock portfolio which represents the DAX® shares with their relative
weightings.
Underweight
Market participants speak of underweighting when buying or selling a
particular type of investment (e.g. shares, bonds and warrants), a region or
sector, ultimately changing the weighting of their depot. This weighting is
usually stated in percent. The additional purchase of securities lends the
respective type a stronger weight in the portfolio.
Analysts often use these terms to express their recommendations to either buy
(overweight) or sell (underweight) shares.
Underwriting bank
A company that lists on the exchange can enlist the help of an IPO underwriter. It overtakes project management and organizes numerous tasks that have to be completed prior to an IPO. These include the creation of a time plan or getting in touch with analysts. An IPO underwriter represents solely the interests of the IPO candidate.
