Investment groups are great! If you can find a group of like minded people willing to do the work.
To be able to have several people working on a single strategy. The way it works is you get people to sign up for an investment club account, and everyone antes up the decided amount, say $5,000. Now you get, say, 5-10 people each looking for good opportunities, then once a week or month, you decide to buy, sell or hold as everyone shares the profits or losses as everyone pooled the same amount.
