Investors should navigate the ongoing market volatility by getting into an exchange-traded fund with a long-term growth story: cybersecurity, according to John Petrides, portfolio manager at Tocqueville Asset Management. His favorite fund is the ETFMG Prime Cyber Security ETF, which trades under the ticker “Hack.” It’s currently down about 25% year-to-date — along with the tech-heavy Nasdaq Composite — but Petrides said it has a uniquely strong selling point going forward. “Investors are very focused on the near-term and macroeconomic situation. But the long-term long-term growth story of more capital being invested in cybersecurity is not going to stop, in fact it has likely been amplified during the pandemic as more of our everyday lives shift to the digital world,” Petrides told CNBC. Stocks have struggled for direction of late as the market gave back some gains from the summer rally following Federal Reserve Chair Jerome Powell’s Jackson Hole speech.
