Dividend Portfolio: Rebalance?

One item I want to keep an eye on with my dividend portfolio is not to get too over weight for any sector. Below I show a chart of projected annual dividends by sector (note these numbers have been multiplied by a mysterious factor to protect the innocent):

Row Labels	Sum of Projected Dividend
Basic Resources	1,440
Bond	2,338
Chemicals	820
Construction	1,957
Consumer	2,702
Defense	788
Finance	5,569
Hybrid	6,778
Insurance	8,975
Pharma	1,018
Pipelines	2,770
Tech	5,380
Utility	6,909
Grand Total	47,445

As one can see, I am over-weight in Insurance. So I am considering selling AXS and then taking the proceeds and buying some more RTN and FCX and then starting a new position in RIMG.

RIMG looks like a pretty interesting tech company. They are projecting double digit growth in revenues in 2012, they pay about a 6% dividend and they have a ton of cash. If anyone knows of a reason NOT to buy RIMG, please fell free to comment.
