However, near-term setbacks could send the index below 2,000.
"In the near term, it feels like the markets are kind of melting up," he told CNBC's "Squawk Box," referring to a move higher in markets driven by investors who don't want to miss out on potential gains.
"I don't see the markets panicking to the topside for any particular reason, other than short covering," Gordon added.
He noted that gains in recent days have been led by the worst-performing sectors since the highs of 2015: energy, financials and materials. He said he has gone short after being long crude futures and risk-on stocks like Netflix.
"I do think there's buying opportunities, but let's get them from lower" levels, Gordon said. He further noted that a significant correction would likely follow once the S&P reached 2,600.
