A trend is a development with a strong, independent and (at least in the medium term) stable dynamic leads. So if, for example, there are not just more candles in rooms in December because it’s Advent and Christmas, but because people really are more and more into romantic candlelight – then that’s a trend. But if it’s only like that for a week or two because a romantic movie came out, and then it drops back to normal, it’s not a trend. Trends are therefore neither random, nor can they be derived from well-known factors (such as the calendar or the weather) – instead, they really reflect the fact that something is changing in people’s behavior.
