NEW YORK ( TheStreet) - When it comes to accessing commodity-producing companies, there are a wide variety of ETF and mutual fund options investors can consider.For instance, funds such as the Market Vectors Agribusiness ETF ( MOO), the SPDR S&P Metals & Mining ETF ( XME), and the iShares Dow Jones U.S. Oil Equipment & Services Index Fund ( IEZ) are strong choices for investors looking to gain exposure to companies that will benefit from specific pockets of strength within the commodities realm. However, in today's environment where strength appears to be present across all reaches of the commodities spectrum, a more diversified product may prove to be the most suitable and effective option for conservative investors. The Market Vectors RVE Hard Assets Producers ETF ( HAP) and the Fidelity Global Commodity Stock Fund ( FFGCX) are two funds which offer investors one-stop-shop access to all walks of the resources industry, offering exposure to miners, energy producers, and agricultural goliaths under one roof. Despite the similar investment strategies of these products, HAP has managed to score a slim lead on its mutual fund competitor throughout the opening weeks of 2011. By digging into the internal workings of these two funds, it is possible to identify slight variations have led to their deviation from one another. For instance, FFGCX's heavier exposure to miners within its top 10 holdings has likely played a role in subduing the fund's gains in recent weeks. Whereas HAP's index is commanded by agriculture and energy-related companies such as XOM, Potash of Saskatchewan ( POT) and Deere ( DE), FFGCX is headlined by BHP which, comparatively has lagged. Vale and Rio Tinto ( RIO) can also be found among the mutual fund's top 10 holdings. Deere is one company that is noticeably absent from FFGCX's top holdings. The recent food rally has proved wildly beneficial for this agricultural machinery manufacturer, lifting shares of DE 13% this year. Looking ahead, the company appears primed for further strength. This week the firm reported record first quarter earnings. Following up the announcement, Deere raised its outlook for the coming year. While HAP dedicates 4% of its index to this firm, within FFGCX, DE accounts for only 0.016% of its portfolio. Ultimately, although HAP has seen a slightly stronger start to 2011, I would not advise investors to write off FFGCX.
