When saving for retirement or looking for solid long-term investment options, many Americans turn to mutual funds to maximize the return on their savings, as well as to put their capital in the hands of professional money managers. Using the Zacks Mutual Fund Screener, we have picked out the 3 top performing mutual funds from the last 3 years based on total return percentage:

T. Rowe Price Global Technology Fund (PRGTX - MF report)

With a total 3 year return of 25.76%, the T. Rowe Price Global Technology Fund has been the best performing mutual fund in the last 3 years. Managed by the T. Rowe Price family and manager Joshua Spencer, the fund seeks long-term capital growth through investing at least 80% of its net assets throughout the world in the common stocks of companies that generate a majority of their revenues from the development, advancement, and use of technology. The company holdings range from small companies to blue chip firms with established records.

PRGTX has been extremely successful over the last 3 years by allocating its assets mostly in large growth companies (47.12%), small growth companies (12.07%), and high yield bonds (24.22%). Its 3 largest holdings are Alphabet Inc. (GOOGL - Analyst Report) with 7.69% of assets, or $208.98 million, Liberty Global PLC (LBTYA - Analyst Report) with 7.13% of assets, or $193.78 million, and Tesla Motors Inc. (TSLA - Analyst Report) with 6.30% of assets, or $171.25 million. The total net assets for the fund are just over $2.7 billion.

PRGTX is actually currently a Zacks Mutual Fund Rank #2 (Buy), and is positioned to continue to be one of the more profitable funds around. With a minimum investment of $2,500 and an expense ratio of .91, this historically high-return-producing fund should be on all long-term investors’ minds.

Pro Funds Internet Ultra Sector Fund (INPIX - MF report)

Coming in as the second best performing mutual fund over the past 3 years is the Profunds Internet UltraSector Fund. This fund’s goal is long-term capital appreciation by seeking daily investment results that correspond to 150% of the performance of the Dow Jones Composite Internet Index. INPIX primarily invests in internet companies or in instruments that provide exposure to these companies.

The fund’s biggest weightings are in the tech industry at 39.65%, other industries with 29.26%, and the finance industry at 12.39%. Its three largest holdings are Facebook (FB - Analyst Report) at 9.28% of assets, Alphabet Inc. at 8.55%, and Amazon.com Inc. (AMZN - Analyst Report) at 7.67%. The fund’s biggest allocations are for large growth companies at 70.30% of assets, and small growth companies with 12.96%.

INPIX’s total return over the past 3 years comes in at a solid 23.06%, and under the leadership of the Pro Funds family and manager Michael Neches it will continue to push for high returns for its investors. Though currently a Zacks Mutual Fund Rank #3 (Hold), this fund has the potential to continue to be one of the top performers for years to come, especially as internet-based companies continue to develop.

Fidelity Select Medical Equipment and Systems Portfolio (FSMEX - MF report)

Finally, with a 3-year total return of 21.05%, is the Fidelity Select Medical Equipment and Systems Portfolio. This fund also seeks long-term capital appreciation, but to do so looks to invest in the common stocks of companies principally engaged in the research, development, manufacture, distribution, supply, or sale of medical equipment.

Not surprisingly the fund’s biggest weighting is in the health sector, with a weight of 75.05%. In regards to allocation, large growth, small growth, and foreign stock garner most of the fund’s assets.  FSMEX’s 3 biggest holdings are Medtronic PLC (MDT - Analyst Report) with 24.8% of assets, Boston Scientific Corp. (BSX - Analyst Report) with 10.99%, and Intuitive Surgical Inc. (ISRG - Analyst Report) at 6.35%.

The FSMEX fund has great deal of potential to continue to its streak of success over the past three years, especially as the healthcare sector continues to grow and evolve. FSMEX is also currently a Zacks Mutual Fund Rank #1 (Strong Buy), placing it near the top of all mutual funds ranked by Zacks.

Bottom Line

One should note that these top-performing funds involve themselves in the technology and health industries, which have seen large amounts of growth in recent years, and still hold great potential moving forward. Because of this, all three funds can continue to be some of the better performing mutual funds available and long-term investors may want to consider them for investment.
