Any Wall Street trading floor is littered with flashing ticker screens with news stories zipping by.

Descriptiv is trying to turn this noise into "what is the most important thing I need to know, now".

Why I find this interesting... many times the catalyst driving a stock is coming from a different compnay and you spend a lot of time chasing down "who/what/why". This is especially common in BioTech where there is a lot of trading on rumor, no news, and you want to know which company has the rumor. Follow the "peer factor" trail here to find out.

Two step process:

1) Shine the flashlight on the catalyst for a stock move - we quantitatively attribute current price movement of the stock from coming from the broad market, your peer cohort or "other" (which generally means its idiosyncratic or a peer we aren't considering). If a peer... which peer.

2) Once a spotlight is on a catalyst - what is the most relevant news driving that one company.

What you are seeing here is just the first step.

Caveats:

Turned off the RT feed (so this will do hourly updates) and removed the news so we could freely show this off at small scale outside of a login. Would love to hear thoughts.

Okay, so micron(MU) is down more than 7% today. This seems to show me an even split between peer contributions and other contributions. How should I interpret that and what should I do about it?

Yep so in this case... that's saying that the peer group (chip/semi-conductors) is disconnected a bit from the rest of the market... and directionally its down. Micron specifcally has some "other" attribution too. Glancing at the other semis... they are mostly down because of just the peer factor.

TLDR; Micron (MU) is leading the peer group down (in contrast to something like LCRX which is in that herd but following).
