Investing wisely and managing your money is essential for achieving financial success. One of the key aspects of investing is building a well-diversified portfolio that helps you reach your financial goals while minimizing risks. In this blog article, we will break down a recent analysis conducted by JAVLIN Invest, which focuses on the ideal number of stocks to include in your portfolio, so you can make informed decisions about your investments.

Understanding Portfolio Diversification

Before diving into the analysis, let’s first understand what portfolio diversification is. In simple terms, diversification means spreading your investments across different types of assets or securities, such as stocks, bonds, or real estate. The primary goal of diversification is to reduce risk by not putting all your money into one type of investment. This is important because if one asset class performs poorly, the other assets in your portfolio can help offset the losses.

The Analysis: Determining the Ideal Number of Stocks for Your Portfolio

JAVLIN Invest conducted an analysis to determine the ideal number of stocks to include in a portfolio by running thousands of simulations with varying numbers of tickers (stock symbols) ranging from 1 to 55. The researchers wanted to find a portfolio size that would achieve a level of volatility (a measure of risk) similar to that of the S&P 500, a widely recognized benchmark for the performance of the US stock market.

Key Findings

The analysis found that a portfolio consisting of only 17 to 30 stocks with low correlation (meaning the stocks don’t move in the same direction at the same time) is enough to achieve volatility similar to that of the S&P 500. This is significant because it shows that you don’t need to hold a large number of stocks to achieve a well-diversified portfolio.

Moreover, the analysis also revealed that a more concentrated portfolio, consisting of higher-quality stocks, can achieve higher returns. This is important because it suggests that focusing on a smaller number of carefully selected stocks can result in better risk-adjusted returns (returns relative to the amount of risk taken).

How to Apply These Findings

As an investor, you may be wondering how to apply these findings to your own investment strategy. Here are some tips to help you create a well-diversified portfolio:

  1. Start by researching and selecting 17 to 30 stocks from different industries and sectors, making sure they have low correlation. This will help you create a portfolio that is more resistant to market fluctuations.
  2. Prioritize higher-quality stocks, such as those with strong financials, good management teams, and a history of consistent growth. This will increase your chances of achieving higher returns over time.
  3. Regularly review and rebalance your portfolio to ensure that it remains diversified and aligned with your financial goals. This may involve selling some stocks and buying others to maintain the right balance.


Investing is an essential aspect of managing your finances and working towards your financial goals. By understanding the concept of portfolio diversification and applying the findings from JAVLIN Invest’s analysis, you can make informed decisions about your investments. Remember, a well-diversified portfolio of 17 to 30 carefully selected stocks can help you minimize risk and potentially achieve better risk-adjusted returns.
