A random Funds Manager buys 200.000 shares from a certain stock. Lets say, thats 2,5% of his Funds capital. Let´s assume further that one share costs 100.-
If you have just 10.000.- on your account, you are also able to use 2,5% of your money to buy that certain stock.
2,5% of 10K are 250.- You can get 2,5 shares of that company!
Do you see where this leads too?
You won´t make that much money profit as the Funds Manager if the rates increase, but measured in % it´s the same!
You are on the same side, involved in the same investment products!
Why not copying the working routine of someone who has already proven to be profitable?
What if you would be able to apply the same principles as the Funds Manager?
