Hamburger chain Shake Shack spiked more than 130 percent in its trading debut Friday after pricing at $21 a share.
Friday's trading values the company at about $1.7 billion, making each of its 63 locations worth roughly $27 million. The stock's performance puts it on track for the second-best debut in the past 12 months, according to Ipreo.
Asked on CNBC's "Squawk on the Street" whether the valuation put considerable pressure on the chain, founder Danny Meyer said, "We cook one burger at a time with one smile at a time, and I don't know how you value that."
Investor and host of CNBC's "The Profit" Marcus Lemonis said he too thought the blockbuster debut put no undue pressure on Shake Shack. Its model of placing locations in high-profile, well-trafficked areas in cities has worked so far, he said.
