Some 29 franchisees, who collectively own and operate 208 McDonald's restaurants in the United States, were asked to give their six-month forecast from 1 (poor) to 5 (excellent). The average response was 1.69, the lowest in the survey's 12-year history.

Previously, the lowest rating was 1.81, which was recorded three months ago.

Those 29 franchisees said their same-store sales fell 2.3 percent in June—2 full percentage points worse than Wall Street expectations, Kalinowski wrote. The respondents expect sales to fall 1.2 percent more this month, whereas analysts were assuming sales would rise.
