It’s almost impossible to answer this. The reason is every stock picking service has a different approach to measuring its track record. Some services like Alpha Picks by Seeking Alpha base its track record on how its picks would have performed historically versus actually buying the stocks. While other services like the Motley Fool and Zacks use rankings for the stocks they recommend. These rankings are constantly changing. This makes it difficult to calculate the return of each recommendation they make.  This also means the investors that use these services can have completely different experiences depending on when they signed up and how long they used the service. Remember, regardless of which service you use, luck and hard work are going to play a massive role in whether you make a profit or a loss.
