BlackRock has cross-listed its iShares Digital Security UCITS ETF on SIX Swiss Exchange.

The index tracks firms with more than 50% revenue exposure to the theme of digital security.

The fund tracks the Stoxx Global Digital Security Index which consists of developed and emerging markets companies that stand to benefit from future growth in the adoption of digital security solutions.

The index targets companies that generate at least 50% of their revenue from the transmission, safeguarding and/or handling of sensitive data, and/or accessing data centres.

To be eligible for inclusion, stocks must have a three-month median daily traded volume (MDTV) greater than €1 million and a free-float market capitalization greater than €200m.

The selection process aims to have a minimum of 80 constituents at each annual review in June. If the screening process is too restrictive, the revenue filter is progressively lowered in steps of 5% until the number of constituents is equal to or greater than 80. There are currently 84 stocks in the index which are equally weighted.

The US and Japan are the largest country contributors with weights of 41.2% and 18.8% respectively. India (8.3%), Germany (5.3%) and South Korea (4.3%) make up the next largest weightings. Unsurprisingly, information technology is by far the largest sector exposure with a weight of 84.8% with industrials (14.3%) making up most of the remainder.

The ETF comes with a total expense ratio (TER) of 0.40% and is available for trading in USD with distributing (Ticker: SHLD SW) and accumulating (LOCK SW) share classes.

The fund made its debut on London Stock Exchange in September and is also listed on Xetra.

Investors looking to access the digital security theme may also wish to consider the more established L&G ISE Cyber Security UCITS ETF (ISPY SW), which launched in September 2015 and has over $710m in assets under management. The fund tracks the ISE Cyber Security UCITS Index and comes with a TER of 0.75%
