El Pollo Loco (LOCO) shares tumbled to close significantly lower in Friday’s regular trading session after the chicken restaurant chain reported weaker than expected earnings figures, and lowered its sales forecast for the year. The stock plummeted nearly 20% to fall below its initial public offering price for the first time since making its debut in July of last year. Meanwhile, shares of Nordstrom (JWN) stood out from other department stores after posting better-than-expected second quarter financial results.
