In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
Widow-and-orphan stock: a stock that reliably provides a regular dividend while also yielding a slow but steady rise in market value over the long term.

In trading bonds and other fixed income securities, various measures of bond duration are used analogously to the delta of an option. The closest analogue to the delta is DV01 , which is the reduction in price (in currency units) for an increase of one basis point (i.e. 0.01% per annum) in the yield , where yield is the underlying variable; see ...
The purpose of Bollinger Bands is to provide a relative definition of high and low prices of a market. By definition, prices are high at the upper band and low at the lower band. This definition can aid in rigorous pattern recognition and is useful in comparing price action to the action of indicators to arrive at systematic trading decisions. [3]
