Why has the BetaShares Global Cybersecurity ETF (ASX:HACK) share price leapt 7% in a month?

Over the past month, the S&P/ASX 200 Index (ASX: XJO) has given investors a reasonably solid performance. Since market open on 4 October, the ASX 200 has gained a robust 3%. But one ASX exchange-traded fund (ETF) has done a few better. The BetaShares Global Cybersecurity ETF (ASX: HACK) has managed to add more than 7% to its value over the same period.

Yes, since 4 October, the HACK ETF has put on an impressive 7.27%, including the healthy 1.5% it's managed today so far. That's almost triple the broader market.

So what's gone so right for this ASX ETF?

Why has the BetaShares Global Cybersecurity ETF HACKed such a good month?

Well, to answer that question, let's check out this ETF's top holdings. So the BetaShares Cybersecurity ETF tracks the performance of the Nasdaq Consumer Technology Association Cybersecurity Index. This aims to provide "exposure to the leading companies in the global cybersecurity sector."

So let's check out which companies this ETF's portfolio is currently most heavily invested in, as of 2 November:

1. Palo Alto Networks Inc (NYSE: PANW) with a portfolio weighting of 6.3%
2. Accenture plc (NYSE: ACN) with a weighting of 6.1%
3. Cisco Systems Inc (NASDAQ: CSCO) with a weighting of 5.6%
4. Okta Inc (NASDAQ: OKTA) with a weighting of 5.5%
5. Crowdstrike Holdings Inc (NASDAQ: CRWD) with a weighting of 5.4%
6. Cloudflare Inc (NYSE: NET) with a weighting of 4.5%
7. Tenable Holdings Inc (NASDAQ: TENB) with a weighting of 3.4%
8. Zscaler Inc (NASDAQ: ZS) with a weighting of 3.3%
9. F5 Networks Inc (NASDAQ: FFIV) with a weighting of 3.1%
10. Cyberark Software Ltd (NASDAQ: CYBR) with a weighting of 3.1%

So the shares with the most weighting (and thus influence) in the HACK ETF are Palo Alto, Accenture, Cisco, Okta and Crowdstrike. Together, these companies make up 28.9% of this ETF's portfolio. So let's see how they've performed over the past month.

Since 4 October, Palo Alto shares are up a healthy 8.3%.

Accenture shares are up 13.15%.

Cisco has enjoyed gains of 6.25%.

Okta is up 12.8%.

And Crowdstrike has managed 12.2% in gains.

So with the top shelf of HACK's portfolio enjoying such a successful month, it's perhaps no surprise that this ETF's pricing has commensurately appreciated.

But investors in this ETF might be used to outperformance by now. Since its inception in August 2016, the HACK ETF has averaged an annual gain of 22.47%. Over the past year alone, investors have enjoyed a gain of 39.26%.
