Understanding the Small-Cap Market and its Risks:

Before diving into the individual company profiles, it’s crucial to understand the small-cap market landscape. Small-cap stocks, typically companies with market capitalizations below $2 billion, offer significant potential for growth but also carry substantial risk. Their share prices can be more volatile than those of larger companies due to factors such as lower liquidity, higher susceptibility to economic downturns, and greater reliance on a smaller customer base. However, the potential for high returns makes them attractive to investors seeking high-growth opportunities. This is particularly true for investors with a higher risk tolerance.
