How many stocks do you think should be in a dividend growth portfolio?

As many as possible, but must be good one. Why?

As a income investor, you will seldom/never sell your shares. Capital gain is great but not pirority.

Because dividend is not guarantee. When u retired, and depend on dividends , if they cut the dividend or reduce the dividend. U in trouble.

Owning more dividend stock is actually a risk mitigation method, for dividend cut. If you own just 1 etf , if it skip its dividend, u whole year no $$$.

FYI: STI ETF only pay 1 time this year instead of 2.

Depends on your capabilities, experience and understanding.

There is no magic number of stocks be it dividend/non-dividend portfolio. Some advocate 10-30 stocks because it works for them, there are certainly many who did very well with less than 10 and also those who had 100 stocks.

Ultimately the decision should be personal and what you should be understanding should be the principles of diversification.

Pros: Reduced volitility/ emotional stress/ active management if using ETFs/diversified funds/ impact on one's portfolio by single event on a company.

Cons: Averaged out returns across different stocks, may have high comission fees entering many single stocks without ETF. Over-diversification gives a false sense of security. (buying 30 stocks can mean buying 3 stocks you understand and 27 you have no clue about) - just another way of looking at it.
