What sets apart mutual fund from other investment vehicles? Asset diversification. The fund may not generate hefty returns, but it can minimize losses. When you invest in mutual funds, you may want to choose the best ones. Below are the five most profitable funds in 2015.

Fidelity Select Health Care Portfolio

Minimum Initial Investment: $2,500

Net Assets: $9.82 billion

Holdings: Actavis Plc, Amgen Inc., and Medtronic Plc

FSPHX invests in companies that create, manufacture, or sell products and services related to healthcare and medicine. Capital appreciation is the fund’s main objective. Normally, at least 80% of assets are engaged in such activities. The fund invests in common stocks.

Baby boomer generation is retiring in droves. Therefore, it increases the demand for products and services offered by the fund’s holdings. Not to mention its 0.76% expense ratio is way below the category average

FPA Crescent

Minimum Initial Investment: $1,500

Net Assets: $20.48 billion

Holdings: Aon Plc, CVS Health Corporation, and Oracle Corp.

This fund seeks the firms’ equity and debt securities. It prefers genuine bargains over almost appealing securities. Looking at their setup, investors can see the prospect of gaining regardless of the overall market behavior. Although the 1.15% expense ratio is high, FPACX has a good track record. It takes less risk than the market, as well as averts permanent impairment of capital.

Vanguard Dividend Growth Inv

Minimum Initial Investment: $3,000

Net Assets: $24.44 billion

Holdings: The TJX Companies, Inc., UnitedHealth Group, and United Parcel Service, Inc.

VDIGX aims to provide steady cash flow to investors by investing in companies that desire to amplify their dividends consistently. These firms have the capacity to grow their earnings per share over time. Hence, raising the likelihood of higher dividends.

It also focuses on undervalued caps and offers exposure to dividend-oriented firms throughout all sectors. However, the only downside is returns from such stocks will mirror returns from the overall stock market during any particular period. Still, this is for investors looking for exposure to dividend-focused companies.

Vanguard Health Care Inv

Minimum Initial Investment: $3,000

Net Assets: $48.54 billion

Holdings: Actavis Plc, Bristol-Myers Squibb Co., and UnitedHealth Group Inc.

For the last 25 years, the actively managed fund invests in local and foreign companies involved in several aspects of the industry, including medical supply firms, pharmaceutical companies, and research firms. VGHCX offers alternative to the retiring Baby Boomers. Its 0.35% expense ratio is pretty much attractive and it has a small yield.

Dodge & Cox International Stock

Minimum Initial Investment: $2,500

Net Assets: $68.70 billion

Holdings: Naspers Ltd Class N, Roche Holding AG, and Sanofi S.A.

DODFX invests in a diversified portfolio of equity securities by companies outside the United States, seeking long-term growth of principal and income. Normally, it will invest at least 80% of its total assets in equity securities of non-American firms, including common stocks, depositary receipts, and preferred stocks.

As of present, about 62% of its assets are based in Europe. Its accommodative monetary policy can lead to substantial short-term gains. But, since monetary policy cannot counter deflation, this should appear as a higher-risk long-term investment unlike other funds.
