How to Build Your Own Investment Portfolio

Create, manage and build your portfolio

Looking to put your money to work for the future? An investment plan is a critical step. Whether you’ve already begun saving or are just starting out, it’s important to have a target in mind. That will help determine how much you need to put away, what level of risk you should take and what investments you choose.

Here’s a four-step framework to help you build your own personalized investment portfolio.

1. Define Your Financial Goal(s)

Name It

Know what you're investing for—is it for your retirement, college education for yourself or a child, general investing to grow your current savings, or some other goal?

Date It

Determine your time frame for when you'll use the proceeds of your investment. Different goals may require different timelines and strategies for your investment plan.

Estimate the Amount

Add up how much you may need for each goal. Our calculator can help you determine how much you may need to invest depending on your timeline and goal amount.

2. Design or Modify an Investment Portfolio

Evaluate Your Risk Tolerance

The level of comfort with risk can be different for each person. Knowing your comfort level can help you determine how much of the market's ups and downs you can live with and find balance in your portfolio. It can help you choose a mix of investments that might suit your situation, depending on how conservative or aggressive you want to be.

Remember that not taking enough risk with your investments is a risk in itself. For goals that are many years in the future, such as retirement for a person in their 20s and 30s, a portfolio that leans more aggressive may align with the longer timeframe until needing the money.

Diversify Your Investment Portfolio

Think about spreading your investments across different types of assets. Markets are unpredictable. The purpose of combining different asset classes is to be better prepared for various market conditions in an effort to provide more consistent, less rocky returns over time.

Diversification should go beyond the general categories of stocks, bonds and cash. Each of these can be split further into more specialized categories to take advantage of different parts of the market.

For example, in the stock portion of your portfolio, you can choose funds that invest in companies of various sizes or locations (U.S. or non-U.S.). You can also choose funds that select companies based on a particular investing style, such as growth or value.

Not confident in choosing your own diversified portfolio? Another option is to use a robo-advisor to get a portfolio recommendation based on questions you answer.

Know Your Decision-Making Style

How will you manage your investment plan? Will you do the research and regular portfolio reviews yourself, or will you also consult a professional for advice and recommendations?

3. Execute Your Plan

Invest in new funds, rebalance or readjust existing investments to align your portfolio with both your risk tolerance and goals.

Whether you like the convenience of having a portfolio that is managed for you, choose to build a diversified portfolio with our no-load mutual funds, or prefer the benefits of using a brokerage account to invest in a variety of investment types, you have choices.

4. Maintain the Plan

Set up periodic automatic investments to help ensure you're building on your investment and putting market swings to work for you, or establish automatic withdrawals to start using your nest egg.

Letting winners run too long can lead to a lopsided portfolio. This increases the risk that your fortunes rise and fall based on the performance of one country, sector, company, or even one stock style. Learn how rebalancing can help you manage risk in your portfolio.

Do you have money in several different accounts—two or more investment companies or your bank? Consolidating investment accounts may give you a clearer picture of your overall financial standing, including whether you’re properly diversified.

Don’t just set it and forget it. Did you marry, divorce or have a baby? Do you want to dial back your level of risk? Would you like to retire earlier than you originally planned? Your investment plan may need adjusting to reflect these new realities.

Keep a Long-Term View

It’s never too early to get started on building your own investment portfolio. The more time you have for your investment to grow and compound, the more likely you are to reach your goals. And we’re here to help you along the way, including offering advice options to help you make sense of your investing world.

Not Sure Where to Start?

Investment Consultants are available to help. Start by requesting a call back.

You should consider all options before making a decision. Our representatives can help you evaluate all of your distribution options.

Investment return and principal value of security investments will fluctuate. The value at the time of redemption may be more or less than the original cost. Past performance is no guarantee of future results.

Diversification does not assure a profit nor does it protect against loss of principal.

You could lose money by investing in a mutual fund, even if through your employer's plan or an IRA. An investment in a mutual fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Rebalancing allows you to keep your asset allocation in line with your goals. It does not guarantee investment returns and does not eliminate risk.
