In the United States, a small cap company is a company whose market capitalization (shares x value of each share) is considered small, from $250 million to $2 billion. Market caps terms may be different outside the United States.
Both the cap-weighted market portfolio and the CAPM model are inefficient. If we assume that the capitalization-weighted market portfolio is not efficient, assuming a pricing inefficiency, capitalization-weighting might be sub-optimal and the degree of sub-performance might be proportional to the degree of random noise.

Stock market indices may be categorized by their index weight methodology, or the rules on how stocks are allocated in the index, independent of its stock coverage.
