1) Small market capitalisation

Small-cap stocks can carry all kinds of characteristics, but the one immutable trait is that they hold a market capitalisation that’s smaller than more established companies. We mentioned before that small-cap stocks typically sport a market cap of $300 million to $2 billion, with anything smaller than that being considered a micro-cap, while the next level up is considered a mid-cap stock.

2) Larger-than-average returns

Small-cap stocks have proven to generate bigger price gains than their large-cap peers when the market moves in their direction. Think of finding a great small-cap stock as getting in on the ground floor, before the big mutual funds, hedge funds, and other institutional investors figure it out.

3) More volatility

Small-cap stocks typically trade far fewer shares per day than their large-cap contemporaries. That relative lack of liquidity makes them more likely to go through significant price swings – so while you can make money quickly with small-cap stocks, you can lose it just as fast.

4) They can be bought in bulk with financial instruments
