Some, like Trentos, simplify the task by relying heavily on their firm's «
focus lists»
of recommended stocks, which are backed up by
credible research.
How much spare time each week do you have to read all the relevant
credible published science papers already available for years, and read existing reports by govt / science / economic / agri bodies on the subject matters, and read the state
of current
research / know how
of existing anecdotal narrow
focused regional / local analysis and the opinions
of experts in their particular field... and then deeply think about all that and come to a rational and reasonable conclusion on it all?
