Overall, 2015 has not been good for the U.S. equity market, caught up as it was in a vicious circle of never-ending woes. It all started with Fed uncertainty, a strong dollar and slumping commodities, and then extended to geopolitical tensions and global growth concerns, especially in China.

Additionally, the U.S. economy, which was growing at a faster rate in over a decade in 2014, has cooled off substantially this year. While healing labor market, a gradual recovery in the housing market, robust auto industry, and cheap fuel are driving growth, persistent weakness in manufacturing activity, plunging oil prices, and shaky consumer confidence are posing threats to economic expansion (read: 5 ETFs for Loads of Holiday Shopping Delight).

As a result, the major indices – the S&P 500 and Dow Jones – are in the red territory from a year-to-date look, losing 0.3% and 1.4%, respectively.

In fact, a number of products have been crushed, piling up huge losses for many ETFs. Below, we have highlighted five ETFs that have been hit badly so far in 2015 and might continue their rough trading in the months ahead if the trends persist unabated.

First Trust ISE-Revere Natural Gas Index Fund (FCG – ETF report) – Down 56.5%

Natural gas producers have been the biggest laggard this year on falling natural gas price. This trend is likely to continue in the months ahead given declining demand, increasing production, and growing global glut. Additionally, the expectation of a milder weather for late December – the key period that drives heating demand – will push the natural gas price lower. The Energy Information Administration (EIA) expects heating bill to decline 13% this winter (read: No Winter Cheer for Natural Gas ETFs?).

Consequently, FCG, which offers exposure to U.S. stocks that derive a substantial portion of their revenues from the exploration and production of natural gas, is down 56.5% in the year-to-date time frame. It follows the ISE-REVERE Natural Gas Index and holds 30 stocks in its basket, which are well spread out across components with none holding more than a 7.1% share. The fund has amassed $172 million in its asset base while charging 60 bps in annual fees. Volume is good with more than 1.7 million shares exchanged per day on average. The ETF has a Zacks ETF Rank of 5 or ‘Strong Sell’ rating with a High risk outlook.

First Trust ISE Global Platinum Index Fund (PLTM – ETF report) – Down 54.3%

The precious metal space has been hit by the double whammy of the broad market commodity rout and rate hike concerns. Robust supply and dwindling demand are weighing on the price of platinum since the start of the year. Additionally, the prospect of a rate hike backed by solid job numbers and moderate inflation has dampened the appeal for platinum. As such, PPLT has fallen 54.3% so far this year.

The fund provides exposure to the companies that are active in platinum group metals mining by tracking the ISE Global Platinum. In total, it holds 18 securities in its basket with double-digit concentration in the top three firms. Other firms do not hold more than an 8.07% share. South African firms take the largest share in the basket at 27.6% followed by double-digit exposure each in Australia, United Kingdom, United States, Russia and Canada (read: Top ETF Stories of November).
