Nov 7 (Reuters) - Blackrock's Richard Turnill :
* "Dividend income is poised to become a larger component of lower overall portfolio returns over the next five years"
* Bond yields have likely bottomed out; "we don't see scope for big rises in already elevated stock market valuations amid tepid earnings growth"
* "Dividends are a big part of the case for equities overall"
* "We see higher inflation expectations, rather than rising real yields, driving rises in nominal bond yields"; this bodes well for dividend growers
* Due to compounding dividends earnings growth, valuations of global developed stocks would need to fall by 30% over next 5 yrs to generate negative returns
* "For now, we see dividend growth opportunities globally within the technology, consumer discretionary and financials sectors"
