Stephens downgraded Sonic stock to "equal weight" from "overweight" and cut its price target to $26 from $32 this morning, the Fly reports.

The firm said that Sonic should reach a better franchised multiple as sales increase, but the current lack of transparency in earnings and sales will dampen share growth in upcoming quarters.

More than 4.16 million shares of Sonic have traded hands so far today vs. the 30-day average volume of about 950,000 shares.
