Marijuana has a bright future, but making money in marijuana is not as simple as buying a few stocks. That is due to absurd valuations, short squeezes, pump-and-dump schemes and the prevalence of the momo (momentum) crowd in marijuana stocks. The momo crowd buys marijuana stocks because they are going up — this is not a good reason for prudent investors to buy marijuana stocks. For those serious about making money in marijuana, there is a better tool. The tool is segmented money flows.
