Stock brokers have no interest in the health of your account. Indeed, they are brokers in name only. They are salesmen for the company, pushing the company product, which has previously been been bought, and now needs to be dumped on someone to make their profit, someone like you for instance. What is he trying to push onto you? Something from their own account. That is why the company is called a Broker/Dealer, in their registration with the SEC. They deal in stocks, not just act as a broker.
When your account is trashed, and you have left in disgust, no problem for them. They will find the next sucker/victim. Why do you think they advertise so much? There are always plenty of new "clients" to be found, sheep waiting to be sheared.
What to do? Learn for yourself how to do DD, and how to read the charts. Takes time, but you're the only one who is responsible. Patience is key. Good luck.
Yes, this stock is boring, but like you say, Brazil is growing and food needs of the world are also growing. The olympic and paralympic games in the future won't hurt either. I guess that by now you can figure out that I am a buy-and-hold kind of guy. From the "old school", I guess. I just like the company and what they do where they do it. Up here in the USA I like SYY.
