Should i go for mcom or ma in economics after bcom?

Dear Sir/ Madam,

I am currently in final level of CA course and already finished my graduation(B com) from IGNOU . Now, I am planning to pursue a master degree course and my two preferable choices are M com or MA in Economics from IGNOU.

I have interest in stock markets and in fututre I am planning to join in any stock Broking company as analyst role. Please, suggest me what course will be more viable for me for better exposure on my area of interest.

Thanks in advance.
