When investing in stock markets, it’s crucial to make the distinction between high-quality and poor-quality businesses across the small, mid, and large-cap spectrums, as well as the difference between the intrinsic value of a stock and the overall value of the company. Certain niche small businesses may still generate significant returns over time if they are held long enough. On the other hand, if one's approach to small-cap investments is merely based on the absolute value of a stock with hopes of a tenfold increase, then it's a misconception. Stock market investing, whether in small, mid, or large caps, should not be driven by unrealistic expectations; otherwise, it leads to nothing but undue stress, rather than substantial returns.
