The PureFunds ISE Cyber Security ETF (NYSEArca: HACK), the first exchange traded fund dedicated to the fast-growing cyber security space, is just over a year old and at this point it is fair to call the ETF, which is home to more than $1 billion in assets under management, a legend.

HACK’s legendary status has also opened the door for leveraged cyber security ETFs. The pioneers in that group are the Direxion Daily Cyber Security Bull 2X Shares (NYSEArca: HAKK) and the Direxion Daily Cyber Security Bear 2X Shares (NYSEArca: HAKD).

HAKK and HAKD seek to deliver twice the daily returns and double the daily inverse returns of the ISE Cyber Security Index, HACK’s underlying index.

HACK’s index “tracks the performance of companies actively engaged in providing services for cyber security and for which cyber security business activities are a key driver of their business model. These cyber security services are designed to protect computer hardware, software, networks and data from unauthorized access, vulnerabilities, attacks and other security breaches,” according to PureFunds.

“HAKK charges 99 basis points and has accrued $3.7 million since launching September 16. HAKD charges 80 basis points and has gathered $4.1 million,” according to CNBC.
