I know that the vast majority wouldn't borrow to invest
Also the vast majority of CFD traders do not make money
So I am expecting a lot of stick for even daring to suggest this!
Not sure if this strategy has a name or has been suggested before. But if you were to use a margin loan to purchase dividend stocks where the dividend would pay for the interest and then pocket any increase in share price or dividend over the interest rate.
IB, for example, offer 2% margin loan on GBP
Obviously the share price and dividend could go down. So possibly best to consider stocks that have stable growth and consistent dividend. Maybe an Investment Trust or dividend aristocrat
