Small cap definition
Small cap stands for small capitalisation and is a term used to group stocks and shares. Sitting below large- and mid-cap stocks, small-cap stocks generally have a valuation, or market capitalisation, of less than $2 billion.
Small-cap stocks can include young and potentially fast-growing companies, and these stocks can generate large returns over time. However, there’s a greater level of uncertainty about these businesses compared with a long-established, already profitable companies, and hence small-cap stock prices can be more volatile and risky than mid- or large-cap stocks.
Some stock index providers have small-cap indices. For example, the FTSE 100 is a large-cap index, while the FTSE 250 is a mid-cap index and the FTSE Small Cap is, as the name suggests, a small-cap index.
