Anyone subscribed or using any investment Research platforms such as zacks, bloomberg, Morningstar etc to gain access to research articles, commentary or reports?

I have subscribed to bloomberg. I found it useful as it can allow me to input my Offer/buy price and units on those funds that I have bought to monitor my overall portfolio. Just that it might be on the high side as it cost about $49/mth.

No. Different people anaylse differently. Most important is you know how to analyse. And if you are a long term investor, short term dip , news or anaylsis doesnt matter.
