Market capitalization is a key metric in evaluating the potential value of a company and serves as an indicator of how much risk you might take on by investing in it. Generally speaking, high market cap stocks are less risky than low market cap stocks due to their larger size and scale; however, this doesn't necessarily mean that they'll always outperform smaller companies with lower market caps. Ultimately, it comes down to understanding the individual dynamics of each individual company and assessing its potential for growth or decline over time.
