Because each investor is unique, there is no one-size-fits-all solution to how many shares of stock a beginner should purchase. The amount of money we have to invest, the commissions we'll incur, the share price of the inventory we're interested in, and our risk tolerance are just a few factors to consider when determining how much stock to purchase. While there is no one-size-fits-all quantity of shares that a beginner should buy, we can establish what is best for us by grasping the fundamentals of stock market investing.

 

Investing in stocks may be difficult, and constructing a portfolio that meets financial objectives is no simple process. The amount of stocks individuals should buy is very subjective and is determined by personal criteria such as their time horizon, risk tolerance, and savings goals, which is why financial advisors do not have an accurate recommendation.

 

When it comes to deciding the optimal amount of stocks individuals should own, diversification is critical. Diversification reduces investment risk and increases the likelihood of earning a higher return, and experts advise investors to invest in various assets across multiple industries.

 

Consider the importance of diversification, how long-term versus short-term goals dictate various investment techniques, and why market situations should inform routine portfolio maintenance.

Is There a Sufficient Number of Stocks in a Portfolio?

Diversification is the greatest strength of any portfolio. When individuals possess diversification, they may more easily minimize risk and weather market downturns, and generate higher long-term profits.

 

As a result, investors will require a diverse range of stocks in various sectors that can act as a check on one another. "A few companies will not provide sufficient broad diversification," Blackwell asserts, estimating that the average investor would require a double-digit number of stocks to achieve adequate diversification.

 

"Anything less than 20 is quite concentrated, and at that point, you're exposed to single-security risk," says Liz Young, head of the investment strategy at SoFi. Your investments may fluctuate by large margins whenever a particular industry or firm changes its prices.

 

According to some experts, a portfolio of individual stocks should contain between 20 and 30 stocks for optimal management and diversification. However, additional research indicates that the magic number is 60 stocks if you look beyond that.

 

Between 1986 and 1999, Ronald J. Suez and Mitchell Price of the California investing firm Roxbury Capital Management discovered that when portfolios contain 60 stocks (or more), investors achieve 89 percent diversification, which means the portfolio is safeguarded against volatility. Anything less than that, the research discovered, can damage your portfolio.

How Many Stocks Should a Portfolio Contain?

While numerous sources may view the "proper" quantity of stocks to purchase in a portfolio, the truth is there is no single accurate answer.

 

The optimal amount of stocks to hold in a portfolio is determined by various factors, including the nation of residence and investment, the investment time horizon, market conditions, and the investor's penchant for reading market news and staying current on holdings.

 

Investors spread their wealth among various investment vehicles to minimize their risk exposure. Diversification specifically enables investors to mitigate their exposure to what is known as unsystematic risk, which is defined as the risk associated with a single firm or industry.

 

While investors cannot diversify away systematic risk, such as the risk of an economic recession dragging down the entire stock market, academic research in the field of modern portfolio theory has demonstrated that a well-diversified equity portfolio can effectively reduce unsystematic risk to near-zero levels while maintaining the same expected return as a portfolio with excess risk.

 

In other words, while investors must accept more systematic risk in exchange for the possibility of higher returns (which is referred to as the risk-reward tradeoff), they often do not benefit from improved return potential in exchange for taking on unsystematic risk.

 

The more stocks a portfolio has, the lesser its exposure to unsystematic risk. A portfolio of ten stocks, especially those from diverse sectors or businesses, is significantly less hazardous than a portfolio of two stocks.

Why Is Diversification of Stocks Critical?

We want to avoid the risk of being concentrated in a single company or industry. There are economic and market drivers — and they do not affect all sectors equally.

 

Stocks are not designed to move in lockstep. A varied portfolio will have subsets in the red and others in the green, as the market is driven by different variables each day. Diversifying one's stock holdings provides exposure to a broader range of businesses and provides stability during downturns. Additionally, it is easier to forecast future risk, allowing for more precise estimates.

 

The portfolio's risk is reduced by diversifying investments while retaining the same expected return.

 

And individuals have a portfolio that is heavily concentrated on a few companies or industries; when one company or industry fails, the entire portfolio fails. Diversification helps prevent this from happening or, at the very least, provides a buffer if one area is free falling.

 

One of the most useful strategies for mitigating risk and diversifying your portfolio is investing in low-cost broad-market index funds such as the S&P 500 index fund, a total market fund, or even funds focused on a particular market segment, such as a technology or small-cap fund.

 

These funds frequently invest in hundreds of firms across multiple industries and strive to replicate the broader market's performance. If an investor chooses to invest in an index fund, he can use it as the primary component of his portfolio and augment it with individual stocks.

How Many Stocks Should a Trader Buy?

These are some recommendations for stock selection that individuals should adhere to maintain a well-diversified portfolio without going overboard.

Avoid Attending Every Party in Town

To understand how to invest in a firm and sector that you are familiar with, which may be any of the 4000 actively traded companies. Invest in the narrative you believe in, not the history promoted by social media gurus.

Increase the Value of Existing Stocks Through Incremental Savings

Increase your current portfolio's value by investing additional savings. Traders are not required to purchase new stocks every month or anytime they have excess funds unless they already own a significant position in existing stocks.

 

The best course of action for traders is to maintain their current stock portfolio, which is matched to their risk profile and financial objectives. Thus, unless your current portfolio is insufficiently diversified or you discover an appealing new stock to invest in, you can continue investing in your existing stocks.

Traders Are Not a Mutual Fund

It is acceptable for mutual funds to contain between 60 and 70 stocks. However, individuals are not mutual funds, and it is practically impossible for a retail investor to investigate and monitor so many companies. The critical factor is how much money was invested; if the allocation was less than 1% or 2% of total assets, there have been few gains despite these equities' huge rises over the last year and a half.

The Number of Stocks Has Nothing to Do with Portfolio Size

Many people assume that the amount of money available for investment should dictate the number of stocks they purchase. However, diversifying the portfolio is critical regardless of the money invested.

Concentrate On Sectors Rather Than Numerical Values

The quantity of stocks in a portfolio is meaningless in and of itself. This is not just about the number of stocks in the portfolio; it is also about their quality. The issue is resisting the temptation to invest in an excessive number of stocks simply because people admire companies in the same sector.

How Many Stocks Should a Beginning Investor Purchase?

New investors should aim to purchase at least ten to fifteen different stocks. The more negligible diversification an investor's portfolio contains, the greater the significance of a single stock. They may struggle to monitor performance if they have too many stocks.

 

Diversification is critical while investing. The objective is to acquire high-quality stocks that investors feel will appreciate over time. However, not every business will succeed, and the majority will have unsuccessful years.

 

A minimum of 10 to 15 different types of stocks gives diversification. Assuming our thorough study, we selected 10 to 15 stocks that we believe will appreciate over time. Assume we've purchased ten $100 stocks, and each stock is weighted equally in the portfolio.

 

Two of the stocks see a 50% decline in value due to market conditions or missing results, and the remaining stocks gain an average of 20% in value. We lost $100 on two stocks but profited $160 on the remaining eight.

 

Due to the portfolio of our holdings, we came out ahead. The majority of newbies make the error of selecting two or three stocks, and negative returns could result from any of the stocks' poor performance.

How Many Shares Can We Buy Based on Price?

First, let us determine the maximum number of shares that we can purchase. Assuming the broker does not charge commissions on stock trades (which most prominent online brokers do), determining the number of shares we may buy with a given sum of money is straightforward.

 

The three-step procedure is as follows:

 

Determine the current share price of the stock we're interested in. who can obtain a quote through a broker or a financial website. We are looking at a recent quote, not a delayed one.

 

Divide the investment amount by the stock's current share price.

 

If the broker permits us to purchase fractional shares, the number of shares we can purchase is determined. If we can only purchase total shares (as is often the case), we will round down to the next whole number.

 

Suppose we want to invest $2,000 in Apple's (NASDAQ: AAPL) stock. According to a real-time stock quote, Apple is currently selling at $160 per share. By dividing these two values, I obtain approximately 12.5 shares. Because the broker does not now offer fractional shares, we can afford to purchase twelve shares of Apple.

Is Purchasing One Share of Stock Worthwhile?

Absolutely. Indeed, with the advent of commission-free stock trading, purchasing a single share has become relatively feasible. We've purchased a single share of stock to add to a stake several times in recent months merely because we had a fair bit of cash in my brokerage account.

 

However, if the broker is one of the few that still charges commissions, even tiny transactions may not be feasible. For instance, if the broker charges $4.99 in trading commissions, we would have to pay more than 17% of the value of our investment to purchase one share of General Motors (NYSE: GM), which is currently trading at $29 per share. If we continue to pay commissions, consider switching to a reputable online broker that has embraced the zero-commission movement.

Is It Possible to Buy Less Than One Share of Stock?

Maybe. Fractional shares have been existed for years, mostly for dividend reinvestment purposes. For instance, if an individual owns a stock position that pays $10 in quarterly dividends and the share price is $40, dividend reinvestment typically enables them to purchase 0.25 additional shares. However, in recent years, brokers have begun to embrace the concept of allowing investors to buy fractional shares directly.

 

There are two significant advantages to investing in fractional shares. First, it enables new investors to have exposure to stocks with a high share price. For instance, if Amazon.com (NASDAQ: AMZN) is trading at $2,500 a share, an investor with a $500 stock could purchase 0.2 shares.

 

Second, fractional share investing enables investors to invest their entire portfolio. If someone had $4,000 to invest and was unable to purchase fractional shares, they could purchase just one share and still have $1,500 leftover. They may invest their full $4,000 in fractional shares and acquire 1.6 shares of the e-commerce behemoth.

How to Maintain an Appropriate Stock Holdings Balance

Diversification can also be achieved by the purchase of huge market indexes that track entire industries or even the entire market. Index funds, or mutual funds that track specific indices, and exchange-traded funds (ETFs), which track indexes and can be purchased and sold like stocks, have simplified the process of diversification for investors by allowing them to do so through a single investment instrument.

Balancing a Portfolio with Index Funds

Though Vanguard Group founder John "Jack" Bogle developed the legendary Vanguard 500 Index Fund in late 1975, it was not the first of its kind. Other institutions embraced the goal of putting investors in control by providing a low-cost method to invest in the entire market, and it quickly gained traction with investors.

 

And it's easy to see why: A mutual fund that follows the whole S&P 500 Index, a collection of approximately 500 large-cap US stocks, provides investors with a low-cost method to track the performance of the country's largest corporations. These businesses operate in various fields, including information technology, finance, healthcare, and energy. Today, these large-cap funds continue to be utilized as a broad barometer of the market's health.

 

Today, index funds strive to replicate a diverse range of indexes — there are thousands of distinct market indices in the United States alone — by investing investor cash in each stock, bond, or other security included in the index. Typically, they must purchase the stock in proportion to its "weight" in the index. Typically it is market capitalization or the total value of a publicly-traded company's shares. This indicates that the fund will be significantly more invested in the shares of the index's more valuable companies.

 

Index funds make investing in the market and achieving quick diversification simple for the typical investor. They're also more economical, with lower fees due to removing pricey fund managers from the mix.

Diversification Using ETFs

Although a prototype of the contemporary exchange-traded fund was launched in Canada in 1990, State Street Global Advisors is largely credited with introducing the first full-fledged ETF in the United States in 1993.

 

Since then, ETFs have grown in popularity as an investment vehicle because they offer many of the same benefits as index mutual funds, such as cheap costs and increased diversification.

 

While trading an ETF throughout the day like a stock, it does not have to be composed of stocks. ETFs can be managed by bonds, commodities, and currencies, among other assets. ETFs enable investors to track the performance of the ETF's underlying assets — therefore, similar to stocks, the ETF's price fluctuates continually based on the volume and demand of buying and selling throughout the day.

 

The "sponsors" of ETFs, the financial firms that originate and administer the funds, rely on sophisticated market mechanisms to maintain the value of an ETF relatively near to the value of the underlying components (stocks, bonds, commodities, or currencies) that it is supposed to represent.

 

In terms of diversification, it's critical to remember that ETFs are generally passive vehicles, which means they track broad market indices such as the S&P 500, Russell 2000, and MSCI World Index.

 

Nonetheless, some ETFs are actively managed and may concentrate their efforts on a particular segment of the market or sector to optimize profits.

 

When attempting to diversify your ETF holdings, keep in mind that the ETF wrapper, or fund structure, does not automatically provide diversification. Investors must consider the fund's underlying constituents — the collective term for the many securities the ETF invests — to guarantee adequate diversification.

 

For instance, an ETF tracking the Russell 2000 Index of small-cap stocks typically invests in the index's 2035 components. In principle, ETF would provide significant diversification – but only within the universe of smaller United States corporations. Additionally, if you invest in a mid-cap and large-cap ETF, you will get greater diversification in your overall stock exposure.

Bottom Line

More important than the number of stocks in a portfolio is its diversification, both in terms of asset class and industry.

 

Portfolio diversification helps mitigate investment risk and enhances the likelihood of earning a greater return. Therefore it's preferable to invest in various assets across different firms, industries, and geographic regions.

 

While investing can be exciting and enjoyable, it should be guided by an intelligent strategy that considers elements such as the investment time horizon and consequent risk tolerance, as well as specific savings goals and associated expenses.
