Stocks to watch on Thursday: Snap (SNAP) - the social messaging stock is still up nearly 200% off the lows, yet the company still hasn't come close to reaching positive financial metrics. Facebook (FB) appears back on the offensive by using Snap product development for their own benefits. Snap shouldn't have a market valuation above $20 billion. Aurora Cannabis (ACB) - the cannabis stock made a dead cat bounce off $3.80. The October corporate update suggests the company is still out of touch with the market realities. Don't touch the stock until management slows down aggressive global expansion to focus on profitable expansion in key markets. American Airlines (AAL) - selling American Airlines b/c Delta Air Lines (DAL) has higher costs along with increased passenger demand is a sure sign the market doesn't understand the airline stocks. The stock bounced solidly off $25, but more confirmation is needed for a double bottom here. Regardless, the stock belongs up in the $50s, but the market can stay irrational for a long time.
