CONT

... the application of conventional mathematics and biology may be of limited utility in understanding the dynamics of ... complex ecosystems. The typical reductionist approach to aquatic ecosystem analysis is the top-down approach. Equational models (top-down attemps at approximating nature) are subject to many limitations ... In general, equational models are not good at dealing with highly nonlinear effects, such as thresholding or if-then-else conditionals, which occur in behavioral and ecological studies.

For the information architect and in content management, "bottom up" refers to collecting all the content with a content audit or content inventory, then making room for everything in an ad hoc manner, depending on the content tools being used, such as website navigation, search engines, etc. The opposite, top-down design, looks at the big picture first to arrange content in its natural context.

English

Subject field(s)
  • National and International Economics
  • Investment
DEF

An investment strategy which first finds the best sectors or industries to invest in, and then searches for the best companies within those sectors or industries. This investing strategy begins with a look at the overall economic picture and then narrows it down to sectors, industries and companies that are expected to perform well. Analysis of the fundamentals of a given security is the final step.

CONT

With ... [the top-down] approach, management relies heavily on macroeconomic analysis. The manager chooses the sectors or, in the case of international management, the countries that are likely to generate higher returns.

CONT

[Top-down approach is] a method in which an investor first looks at trends in the general economy, and next selects industries and then companies that should benefit from those trends.

CONT

Les partisans de l'approche descendante ou top-down (certains parlent de l'approche E-I-C pour economic-industry-company approach) croient que la conjoncture économique générale (qu'on appelle aussi la macro-économie) et la vigueur d'un secteur industriel donné ont un effet considérable sur le rendement d'un titre en particulier.
