ST Engineering - Buy or Sell?

ST Engineering has been on a downward trend. The initial reasons why i purchase this share is for dividends but i can't lose track of the profitability of the company. 

This is my first time attempting to make sense of the finance statements so let's give it a go! Grateful for any tips and tricks along the way!

ST Marine
- one of the subsidiaries of ST Engineering
- (36%) fall in EBIT 
- shipbuilding (one of three main areas of business beside ship repair and engineering) took a bit hit of (75%) for second quarter
- industry trend: Shipbuilding is in a difficult period due to too many shipping orders. Unlikely to trend up in near term. 

ST Kinetics
- one of the subsidiaries of ST Engineering
- (50)% fall in EBIT 
- automative dropped 89% 
- other areas would include: 

ST Electronics
- one of the few subsidiaries with higher profit of 10%
- software system up 33%

ST Aerospace
- (5%) in EBIT

Well, no good news at all, no wonder ST Engineering is on a downward trend. Better keep this on my watchlist.
