Hi Jason,
I guess it depends on your reasoning for a short-term hold. Are you intending to trade these stocks, or buy and hold them as part of a broader strategy. All three are commodity based and have been beaten up quite a bit. All are sitting on losses north of 30% despite the recent bullish market sentiment.
Methanex is tied to the price of methanol. It cut the dividend by almost 90% in late April and lost its status as a Canadian Dividend Aristocrat. If you take a look at its five-year chart it hasn't done much. At the beginning of 2018 it caught a bid only to come crashing down shortly after. There isn't much upside in terms of growth, and it is not one I would hold for any long period of time.
Chemtrade has been in a slow and steady downward trend for five years. It also cut the dividend (by 50%) in early March. Expectations are for negative earnings, and low single-digit revenue growth. Not one I would add to my portfolio.
In my opinion, Teck is the best of the trio, but that isn't saying much. The company eeked out a 5% gain over the past five years, but it lost 52.54% over the past decade. The company has no consistent dividend pattern as earning have been all over the map. Expectations are for negative earnings growth over the next couple of years. Again, not one I would add to my portfolio.
All three are very volatile as they are tied to commodities. This makes them prone to big price swings and are best held by investors which have a higher risk tolerance.
