Downgrade feeds can be just as noisy as upgrade feeds. A brokerage may cut a price target but retain Buy, or lower estimates while maintaining Neutral. Those are potentially useful events, but they are not recommendation downgrades.

GMR's downgrade tracker includes only more negative rating moves and stores target changes separately.

The catalyst determines the information value

A downgrade caused by lower earnings estimates or deteriorating free cash flow says something different from one based mostly on valuation after a strong share-price run. Both can matter, but they should not be interpreted identically.

The tracker therefore gives the stated rationale its own field instead of reducing the action to one red label.

Breadth can matter more than one firm

One downgrade may reflect an idiosyncratic model. Several firms cutting ratings or estimates around the same catalyst can indicate a broader reset in expectations.

That is where the tracker becomes more useful as a historical dataset: clusters of actions can be compared with subsequent earnings revisions and price behaviour.
