70% broad market + 30% high dividend stocks - can be done. But I see it like the others: too lumpy. I would distribute the 30% of individual shares among at least 6 companies, better 10.
@randomdude but his savings rate is not enough for this If he has been saving for a year and 30% is 400€, then I would not split it into 6 titles Therefore, it is better to first invest everything in the etf and if you can invest more at some point, he can also get individual titles in addition
