Short term v long term

Running with a full portfolio and has been a good move, picked up some nice profits at the beginning of last week, have made about 6k profit since starting. Starting to change my attitude towards investing. I always saw short term trading as riskier than long term.  Andy B, my go to guy at 1Wealth has been telling me if short term trading is done right than it is safer than long term investing. He feels there is more risk of volatility but in terms of finding winners, it’s easier to predict the movement of a stock next week then in 12 months time. I can see his point. It sought of applies when you’re running something like the 1Wealth software, but I don’t think an average joe would be able to do the necessary number crunching to cover themselves against the short term price fluctuations.
