A stellium would show focus and great activity in the area of life it influences because many of the houses in the chart would lead back to the stellium through house rulerships. This, as well as the planets in the stelliums position in a certain sign/house would raise the importance of that topic immensely.
In your chart you would have a stellium by house - the 9th - as you have 4 planets (ignoring the question mark) there. This could mean that you have a lot of interest in 9th house matters - philosophy, long distance travel, law, higher learning and other such things that act as an expanding of your physical, mental and spiritual boundaries.
To get more specific, a study of the planets, their dispositors and their aspects + house rulerships would be necessary.
