Investors appear to be losing their appetite for Shake Shack.

Shares of the burger chain sliding today on weaker than expected guidance and are now down more than 60% from their 52-week high.

Josh Brown is not perturbed by the report. "If you're a real shareholder, you'd prefer to see the company give conservative guidance. They are going to do 2.5-3% same-stores sales this year which is perfectly fine," Brown said.

The Halftime Report trader sees positive future trends and remains a long-term investor in the stock. "I can see a bigger picture, which is a secular shift to higher quality food and this is going to be one of the winners," he said.

Some analysts raise concerns over labor costs, while Brown praises Danny Meyer's hospitality expertise. "Meyer wants to have the best customer service experience and people working in his stores. If he has to pay them more than McDonald's or Arby's so be it," Brown added.

Brown is bullish on Shake Shack's new menu items and expansion plan.
