Form 8938/capital gains

Hello,

 

I need to report form 8938 because I hold a couple foreign brokerage accounts. These accounts should be getting more worth every year. Lets say in the beginning 2019 they were worth $100000 and in the end of 2019 $150000. This is not considered capital gain right? (because I don't sell or buy, I just hold these acoount)  So what do I have to report? Only the maximum value and the little dividend that has been paid by these accounts? 

 

Thanks
