Investment in shares by company

The company has recently sold one of its property and wishes to invest this money in listed shares (investment in shares is included in MOA as the ancillary object)

Now, my question is since the company has no other income from any other source does investment in shares becomes its Main Object and should be included in Main object or shall remain in ancillary object as it is the company's money which is being invested and not soliciting to others.

Thanks in advance.
