  • Small-cap stocks have been outperforming in recent times as compared to the mid and large cap stocks.
  • Such stocks are small in terms of market capitalisation but have huge growth potential.

Several research and studies carried out over the time have indicated that the small cap company shares have outperformed the larger ones. However, a greater level of uncertainty is also involved in these businesses in comparison with the already established, financially stable companies. Hence, the prices of small-cap stocks can be more volatile and riskier than the large-cap and mid-cap stocks.

If we go by the terminology, small cap is a term that stands for a group of stocks and shares having a smaller market capitalisation of more than £300 million, but less than £2 billion. Such stocks include young and potentially fast-growing companies because of their size and are known for generating large returns over time. The small cap stocks attract the investors more because the earnings of such companies grow faster and in a more sustainable way.

Here we will be discussing some of the small cap stocks which have good overall growth prospect and can be kept on the radar for this year.
