Duration (finance) – the weighted average time until the various cash flows from a security, such as a bond, are received; Duration (music) – an amount of time or a particular time interval, often cited as one of the fundamental aspects of music; Duration (philosophy) – a theory of time and consciousness first proposed by Henri Bergson
Duration (French: la durée) is a theory of time and consciousness posited by the French philosopher Henri Bergson. Bergson sought to improve upon inadequacies he perceived in the philosophy of Herbert Spencer , due, he believed, to Spencer's lack of comprehension of mechanics , which led Bergson to the conclusion that time eluded mathematics ...
Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the ...
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world , is the second , defined as about 9 billion oscillations of the caesium atom.
Modified duration can be extended to instruments with non-fixed cash flows, while Macaulay duration applies only to fixed cash flow instruments. Modified duration is defined as the logarithmic derivative of price with respect to yield, and such a definition will apply to instruments that depend on yields, whether or not the cash flows are fixed.
is the time between two events as measured in the moving reference frame in which they occur at the same place (e.g. two ticks on a moving clock); it is called the proper time between the two events; t is the time between these same two events, but as measured in the stationary reference frame;
Whether you take an aggressive or conservative approach to investing, your asset allocation is likely to include some bonds. When reading about or researching bonds, you’ll hear about duration ...
