I think trading requires planning and management, and also a good dose of composure.
In some ways it can remind you of gambling, generic sports betting, but in some ways if you know the news before others, it can be a profitable job with very little risk. Of course you need to have a huge network
When the market goes down, those who are hardcore trading will stick to trading only, mostly buying. But some of the less rooted ones might move to gambling because they are in it for the money - an attitude that leads to losses.
They will often find games that they dont even know about and just bet on the possible winning side and try their luck. This happens because it is their greed and addiction to gambling that is fueling the process and not logic.
Knowing the news, is something that is not going to happen to everyone - I still doubt if anyone other that those very close to the team actually have any news.
