Savings and Investments

To maximize your long-term savings, your HSA funds are placed in one, two, or three types of balance accounts.


Your National Advisors Trust of South Dakota, Inc.’s Summit HSA program requires the first $500 of your HSA funds to be maintained in a “Cash” balance account. This serves as the base component of your HSA and is “liquid.” Although the money in the cash account does not earn any return, amounts deposited beyond the first $500 automatically flow into “Savings,” which earns interest on a daily variable rate.


The second HSA balance account component offered by NATSD is a “FDIC Insured Savings Account”. This fund is also “liquid,” meaning that your savings balance is accessible whenever you need more money than is currently available from your cash balance account. Interest earned is shown in the “Account Owner’s Disclosure” section below. The earnings post to your account monthly.

An added feature of your savings account is the option of using the Summit Mastercard® debit card. Your card, if made available by your PSP and elected by you, is directly connected to the funds in your savings account. This option makes accessing your HSA funds as easy and convenient as a swipe of the card.


There is a third, and optional, balance account component of NATSD’s HSA program. Investments, if made available by your PSP, and elected by you, allow you to invest funds into a variety of Mutual Funds.



The Summit HSA Investment Program offers qualified account holders a diverse range of investment alternatives to choose from, along with five professionally-managed model portfolios that support varied investment objectives and risk tolerance. This investment program is intended for long-term investments only and is not to be used for short-term cash availability. Click here to view a list of available funds.

Professionally Managed

DataPath Investment Advisors, Inc. (DPIA) is the investment advisor for National Advisors Trust Company and HSAToday & Summit HSA. DPIA screens, selects and monitors the investment options and constructs and maintains the model portfolios. DPIA is a related entity of DataPath Financial Services and DataPath, Inc.

What model portfolios are offered?

The model portfolios, listed from lowest to highest risk levels, include:

Conservative Growth Portfolio For the Investor who seeks to allocate a large percentage of their portfolio to lower-risk securities such as fixed-income securities.  The main goal of a conservative portfolio is to protect the principal value of your portfolio. That is why these models are often called “capital preservation portfolios.”  Even if you are very conservative and are tempted to avoid the stock market entirely, some risk exposure in selected funds can help offset inflation.  Suggested time horizon for this risk allocation is at least 5 years.

Moderately Conservative Growth Portfolio For the Investor who seeks to preserve most of the portfolio’s total value but is willing to take on some risk for inflation protection. A common strategy within this risk level is called “current income.”  This includes securities that pay a higher level of dividends.  The suggested investor’s time horizon least 5 to 8 years. 

Balanced Growth Portfolio For the Investor who seeks a balance between preservation of account value and portfolio risk.  The goal is a near even split between low risk fix-income securities and higher-risk growth securities.  This strategy also includes securities that pay a higher level of dividends.  The Investor’s time horizon for investing should be medium term or greater than 8 years.

Moderately Aggressive Growth Portfolio For the Investor who has a longer-term strategy (greater than 10 years) and willing to take a medium to higher level of risk to achieve portfolio growth, while still diversifying the portfolio by including fixed-income securities.  The strategy is often called “capital growth” strategy.  To provide diversification, the portfolio includes fix-income securities.

Aggressive Growth Portfolio For the investor with a long-term investment strategy (greater than 12 to 15 years) and willing to accept their portfolio value can fluctuates widely from day-to-day.  Your main goal is to achieve long-term growth of capital. The strategy of an aggressive portfolio is considered a “capital growth” strategy. To provide diversification, investors with aggressive portfolios usually add some fixed-income securities.

What are the benefits of investing your HSA funds?

Many Americans will depend on personal savings and investments during retirement. Utilizing your Health Savings Account as a long-term investment vehicle is an excellent way to add to your retirement strategy. Whether you are a current HSA account holder or you are just now enrolling, it’s a good idea to consider investing some of your account funds. Here are just a few reasons why:

  • Tax-Free Investments: All contributions and earnings in your HSA are considered tax-free by the IRS. They will not be taxed unless you withdraw them for non-medical reasons.
  • Portability:  There is no use-it-or-lose-it rule associated with HSAs. HSAs are owned by the account holder and roll over year after year. Even if your employment status changes, the money in the account is yours to keep.
  • Flexibility: You can change the amount you want to invest and the way the funds are invested. Plus, you can always access the money in your account if the need arises.
  • Multiple Investment Options: Pick from one of four investment models or create your very own custom investment portfolio.
