Stocks to watch on Monday: Under Armour (UAA, UA) - the stock is sinking due to the headlines of a accounting probe. While one can't predict the outcome of a DOJ/SEC probe, the regulators have already spent 2.5 years spinning their wheels. Clearly, no smoking gun exists. Cutting the revenue guidance for Q4 doesn't help matters, but Under Armour does expect to beat EPS estimates due to lower sales of off price items. Outside of the accounting probe, the margin improvement is supportive of a rebound. Look to buy the cheap stock here at $18 with cash on the sidelines in case Under Armour takes another hit. Twilio (TWLO) - the company cut EPS targets just provided a couple of weeks ago that tanked the stock. Twilio now only expects to earn $0.12 to $0.13 for the year meaning the Q4 guidance is now negative and much farther below the original $0.07 consensus estimate. Aphria (APHA) - initially jumped on doubling of production capacity to 255,000 kg until the market woke up to the over supply scenario. For now, adding capacity isn't a net positive for the industry.
