Market cap terms
Traditionally, companies were divided into large-cap, mid-cap, and small-cap. The terms mega-cap and micro-cap have since come into common use, and nano-cap is sometimes heard. Large caps have a slow growth rate as compared to small caps. Different numbers are used by different indexes; there is no official definition of, or full consensus agreement about, the exact cutoff values. The cutoffs may be defined as percentiles rather than in nominal dollars. The definitions expressed in nominal dollars need to be adjusted over decades due to inflation, population change, and overall market valuation (for example, $1 billion was a large market cap in 1950, but it is not very large now), and market caps are likely to be different country to country.
