Stocks to watch on Thursday: HEXO (HEXO) - the CFO resigning last week was a massive red flag. The stock is down nearly 20% following a quarter where the company saw weak revenues after predicting a doubling this quarter. The company discussed slow sell through due to a lack of stores in Canada and too much supply now pressuring prices. The news is bad for the whole Canadian cannabis industry and the huge guide down will lead to massive losses. Don't try to pick the bottom here. Delta Air Lines (DAL) - the airline beat EPS estimates again, yet the stock is down another 5% as the market panics on perceived downside guidance for Q4. Delta will earn over $7 per share with the stock trading at only $50. Just buy this airline stock or virtually any airline stock on the weakness. Aurora Cannabis (ACB) - the leading Canadian cannabis producer is back below $4 as the fallout from the HEXO warning hits the sector hard. The company is in the process of flooding the market with cannabis and the initial signs in the industry is that too much supply already exists. Aurora Cannabis still plans to generate up to 5-6x the output of the June quarter. Avoid the stock until the company rationalizes output to better align with actual legal demand.
