That is, rather than hold bonds or cash, Edelman believes long-term investors will be better served with equities.
Of course, that doesn't necessarily mean buy stocks today.
Edelman said rather than fear volatility, individual investors should hope for it—and leverage it.
Over the past several years, "when the market has dropped, it's been a buying opportunity," Edelman said.
And given all the tailwinds in the market, including the to increase stimulus, Edelman sees every reason to embrace equities all the more.
Therefore, the next time shares sell off, don't panic. Instead, Edelman said, identify good companies and then buy on the decline.
