There is a debate between investors who believe in concentration and those who believe in diversification. I think there are few stock market analysts skilled enough to focus on fewer than 12 stocks. If adding an investment to a portfolio does not reduce the risk of the total portfolio beyond what it costs in terms of potential returns, further diversification would be overdiversification. Most experts believe that 15 to 25 individual investments are enough to reduce non-systemic risks. Portfolio diversification involves the integration of different investment vehicles with a large number of characteristics. The diversification strategy requires the balance of different facilities that have only a weak positive correlation between them – or, better yet, a real negative correlation. A low correlation usually means that plant prices are probably not going in the same direction. This can be defined as a minor adaptation to an existing product or service with regard to market conditions such as climate, legislation and regulation, and cultural relevance.

This is the easiest way to diversify, as the instruments needed for the following adjustments are easily accessible to most companies: the goal of portfolio diversification is portfolio risk management. Your risk management plan should contain strictly enforced diversification rules. Studies and mathematical models have shown that maintaining a well-diversified portfolio of 25 to 30 stocks offers the least costly level of risk reduction. Investing in more securities generates other diversification benefits, but with a considerably lower rate.
In general, periods of exuberance, confidence and high profits foster a diversified trend; Periods of consolidation favour the concentration and reduction of less than exceptional companies. Generally speaking, attitudes and mentalities related to diversification or concentration are influenced by the performance of companies and actions and much less, if at all, by thinking about market needs and employment. . . .
