Buying at Tops/ and Bottoms recently

If you have noticed I spoke about pot 8 years before they legalized it, but having a notion as to the trend doesnt make you money. The hard work is finding and verifying your investment pick which I did not do. I lazily picked Universal Tobacco for this but in reality it was Canopy Growth. Even though I missed the 'easy' money, it's always a good time to buy the top when one of the largest liquour companies takes a 20% interest in the company. And to my astonishment its so they will market liquid Cannibis. Go figure. Canopy Growth is 2 billion dollar CAD but if they are the leader and at the cost of cannibis and the expected demand, this is chump change and if you hold it for a long time, they will pay a dividend most likely. As for buying at bottoms, telecom FTR which pays a 20% dividend. Its crazy to buy, but yet they keep paying a dividend. And General Electric which cant seem to have good news anymore is maybe a buy as I have been buying and losing money on this sinkhole since 2001.
