When I started b4 learning from this and other sites, I used 2 investment companies. I do not regret it as I learned from them too. I also tried a robo investor . Now I am self directed.
The one thing I seem to do differently from most is my FIs were 90% into buying individual stocks. So while I was charged a fee, I was not charged an additional fee for a portfolio made up of mutual funds. End of the year performance was measured against the index after commission. In the years I followed this plan, I ended up around the index after commission.
Since achieving index was the end result and a good goal for my life plan, I decided index investing reduces individual stock risk. To be fully transparent, I still own some stocks from that period given their continued growth and capital gains.
