The first thing you should have in mind is how you can calculate the dividend yield. The dividend yield is the dividend paid for each share divided by the price you would have to pay to buy one share.
In addition, you should compare the dividend yield with previous years and with other similar companies in the sector to be able to judge whether it’s high or low.
In general, a low dividend yield can either mean that the company is not distributing a lot (in other words the dividend per share is low) or that the value of the share has appreciated significantly. The first one can be bad especially if it is due to lack of profitability or even losses. It can however also mean that the company chooses not to distribute it’s profits (Apple for example).
The latter is good since it means that the market considers the stock as a good investment.
