It is a fact that dividend stocks are hot this year. More so, some of world market experts are telling investors of all category to be more careful. Specifically, investors are taught and advised to identify companies that have high potential increase instead of finding those with high profit.

Explored by MarketWatch, writer Jeff Reeves and Bob Phillips, the managing principals of Spectrum Management Group, this ideal came about. However, there was some overlap between their stock recommendations.

More so, in the report, Bob Phillips claimed that the most important factor when considering a dividend stock is the likelihood of big dividend increases over time. Rising dividends are much more likely if a company's free cash flow or the remaining cash flow after capital expenditures leaves plenty of so-called headroom for higher dividend payouts.

He furthered that it is important not to overpay for a stock, which may be a tall order considering that we're seven years into a bull market and that this year's market gains have been driven by dividend stocks.

The report took a more keen evaluation into the S&P 1500 Composite Index, which includes the S&P 500 Index SPX, +0.43% the S&P 400 Mid-Cap, Index MID, +0.52% and the S&P Small-Cap 600 Index. This is to identify well the possible dividend-stock bargains in every sector.

In each of the 11 sectors, what came to the list are the top three companies with forward price-to-earnings ratios. This is based on compromised 2017 earnings estimates that are lower than the aggregate. The said 11 companies also have dividend yields of at least 3%, with headroom to raise dividends, based on free cash flow yields, and are expected by analysts to increase their sales by at least 1% in 2017.

Philipp Van Doorn and the rest of his team calculated free cash flow yields by dividing free cash flow per share for the past 12 months by the closing share price on Sept. 30.

It is given that any screening approach has its flaws. An example for this is a company trading at a low price-to-earnings ratio relative to peers could have some major problems.

To make things clearer, here are all 29 stocks that passed the screen, broken down by sector:
