More than half of advisors refuse to let their clients invest in cryptocurrencies, meme stocks or the latest “hot” ETFs, according to a survey of advisors by Incapital released Thursday.

Too many clients are confused by these new types of investments to make them reasonable bets, according to the “Incapital Pulse Survey.” A meme stock is one that’s performing well more because of its social media hype than for its performance, and some trending ETFs also sell more for reputation than value, according to Experian.com.

Sixty-seven percent of the 346 financial professionals in the Incapital survey, which included wealth managers, fiduciaries, financial planners and brokers from more than 50 broker-dealers and RIAs, said their clients do not understand these new, complicated investments, some of which were being recommended to them by their adult children.

Eighty-nine percent of advisors said their clients do not realize how volatile the newer types of stocks can be. But the clients are curious, more than half of the advisors said, and 35% said their clients want to invest in them.

Part of the reason financial professionals are refusing to let their clients indulge their curiosity is that the firms offering these securities do not provide sufficient information for the advisor to educate the client, 43% of advisors said.

“The popularity of investments like cryptocurrencies has taken everyone by storm and reveals a generational divide,” said Chris Mee, managing director and head of wealth management solutions distribution at Incapital, in a statement. “Younger investors have time on their side and can afford to take the potential risks that accompany these types of investments.

“Older investors approaching or in retirement might be tempted to take the risk, but they may lack the time needed to recover from the impact of substantial losses, and not just from an investment like cryptocurrency, but even from overexposure to equity market risk. Retirement-minded investors may benefit from risk-managed strategies that help them stay invested for growth but with protection from too much downside risk exposure,” Mee said.

The financial advisors surveyed said they see the greatest risks over the next six months in cryptocurrencies, followed by bonds and meme stocks. They see the greatest opportunities over the next six months in equities, large-cap value stocks and emerging market plays, the survey said.

The survey also queried advisors about the pandemic and the return of people to offices after working remotely.

Approximately one-third of the surveyed advisors said they would require their staffs to be vaccinated before they return to the office. Another third said they would not require it, and the last third have not decided yet whether they will require vaccinations. Sixty percent said they would inform clients whether their staffs have been vaccinated.

A little more than half of advisors said they are already back to a normal, in-office schedule, an increase from 42% in December. Only 13% said they will not have their employees fully back in the office this year. Twenty-six percent said they are having in-person meetings with clients now, up from just 12% in December, while 46% plan to wait until the second half of 2021, and 21% said they will likely start in 2022.

“The good news is we’re seeing a lot of progress,” Mee said. “It’s been a challenging time, and advisors have been incredibly resourceful and committed to helping their clients manage volatile markets, all the while being displaced from the office. Working virtually, we learned invaluable lessons about client communications, and about being flexible, accessible and responsive.”
