Stock market investors often debate whether to invest in small-caps (for high growth) or large-caps (for stability). But right in the middle lies a sweet spot: mid-cap stocks. They combine the growth potential of small-caps with the relative stability of large-caps, making them an essential part of a diversified portfolio.
In this guide, we’ll explore what mid-cap stocks are, why they matter, their risks, how they fit into algo trading, and practical tips for Indian investors.
