National CineMedia faded to black and blue after the multiplex advertising network lowered its outlook for the new quarter. It's generally been a bad year at the box office attendance-wise, so this may not come as a surprise, but it's problematic that National CineMedia's warning is about the final quarter that has yet to play itself out.

Despite a mostly buoyant market last week, Volcano's stock erupted to the point where it closed lower in four of the five trading days. There was no material news on the intravascular ultrasound specialist.

Citi downgraded shares of FXCM, after the foreign currency brokerage reported disappointing trading metrics for the month of September. FXCM's strength came largely from its high-volume institutional customers that generate lower margins than its retail customers.

Zep investors bugged out after the maker of cleaners and pest control products posted disappointing quarterly results. Zep clocked in with lower adjusted earnings than it did a year earlier. Wall Street was banking on a slight improvement.

L&L Energy also closed out the week with a double-digit percentage hit. There was no substantial news on the company with Chinese coal mining interests. L&L Energy will make a presentation at the RedChip Small-Cap Equities Virtual Conference later this week, giving it a golden opportunity to sell its bullish story.

It was a rough week for these five stocks. Let's see if they bounce back.
