Do you think yield is more important than dividend growth?
Well, it depends on how you define "yield." If you're referring to the interest rate that your bank pays you, then yes. In that case, it's far more important than dividend growth.
But if you're talking about total return, or what's known as "total return on investment," which includes the value of dividends and capital gains, then no: we still need some kind of growth.
Let's say you have $10,000 cash sitting in a bank account that earns 3% interest per year. If you leave it there for 10 years and then take out $11,000 at the end of those 10 years, your total return is $2,000—which means your yield was 2%. (That's not even enough money to buy an iPhone X.)
Now let's say you have an investment portfolio worth $1 million with a 10% annualized return over a decade. That means at the end of 10 years, your portfolio will be worth $1.1 million—and if all you do is reinvest your dividends every quarter, then your total return will be 11% annually over those 10 years as well.
