Can i file itr-4s when i have investments in stock?

Hello,

I am filing ITR for 2015-2016 (AY 2016-2017), my income is from the following:

eCommerce payments from eBay, Amazon for selling items and I have some investment in stocks (share market) and some investment in a local private company.

Gross receipts would be around 40,00,000 INR and my investments are 4,00,000 and 3,00,000 respectively.

I do not have any property, or any other asset. I do not have any professional income for the mentioned year.

In this case, can I file ITR-4S?

Thank you for your time.

Best regards.
