Matthew Caruso is a position trader, holding his stocks for weeks or even months at a time.
Matthew Caruso has been trading stocks since 2008, first professionally for Canada's National Bank and then personally since 2014.
"What made this year difficult was you had to balance, one, a very weak market, but yet, there were very strong industry trends within that weak market," Caruso said.
Coming into the year, he noticed that the oil market was in tight supply, which pushed other commodities such as natural gas and fertilizer up as well.
For example, if he has exposure to too many oil stocks, one news headline could plunge the entire sector.
