2017 was the first time I started thinking seriously about investing money. Many mistakes were made in the beginning, however, slowly after doing much research, I was able to establish a good investment strategy. There are a lot of ways to invest your money today. These include your run of the mill ETFs and index funds, REITs, good old stocks and for the hands off investor — robo-advisors.

Things included are tax loss harvesting, free dividend re-investment, selecting and investing into new investments and establishing an optimum portfolio with good asset allocation based on a risk assessment questionnaire. Just so it is clear, my risk level in my Wealthfront account is set to the maximum as I am in my early 30s.

It is true, Wealthfront does tax loss harvesting every so often on this account. So I decided to find out if this truly helps and if they managed to keep losses minimized during the Covid-19 market turmoil in March 2020. To my surprise, the…
