The global stock market has been on a spectacular ride this year and is heading for its best year since 2009. The rally was mainly driven by strengthening economic fundamentals, booming trade, strong corporate earnings and a rise in commodity prices. Additionally, investors’ unstoppable enthusiasm for technology stocks, optimism over Trump’s tax reform as well as rise in oil price added to the strength.

However, volatility and uncertainty kept crossing the path as geopolitical tensions, political instability in Europe, Washington turmoil, Brexit concerns, and overvaluation are weighing on the markets.

Given this, most corners of ETF investing have performed exceptionally well while a few areas are lagging. Below, we have highlighted the best and worst zones of 2017 and their ETFs:

Technology

Technology has been the star performer this year with ARK Innovation ETF (ARKK – Free Report) topping the list with 87.3% gains. A massive surge came from encouraging industry fundamentals, a rising interest rate scenario, Trump’s tax reform, and the emergence of new technology such as cloud computing, big data, Internet of Things, wearables, drones, virtual reality devices and artificial intelligence. Additionally, the surge in bitcoin prices is a big boon for the disruptive-companies focused ETF.

This is an actively managed fund focusing on companies that are expected to benefit from the development of new products or services, technological improvement, and advancements in genomic revolution, Web x.0, and industrial innovation. It holds 52 stocks in its basket with none having more than 6.5% share. The ETF has amassed $382.3 million in its asset base and trades in a good average daily volume of around 150,000 shares. The expense ratio comes in at 0.75%.

Metals & Mining

VanEck Vectors Rare Earth/Strategic Metals ETF (REMX – Free Report), which offers exposure to companies engaged in producing, refining, and recycling of rare earth and strategic metals and minerals, is on fire gaining 79.7%. The impressive rally came on the back of an expected boom in demand for rare earth minerals. Additionally, China, which produces over 90% of the world’s rare earths, has set production caps and export quotas on metals, which has contributed to price rise.
