We grade stocks. Next, a campus social network.

Meridian grades US-listed stocks and funds from 0 to 10 and publishes how each grade is calculated. Agora, now in development, is a social network open only to people with a verified US university address, where each campus sees only its own posts.

Meridian

A 0 to 10 grade for US-listed stocks and funds.

  1. Each name is graded on six factors: valuation, growth, profitability, momentum, analyst expectations and financial health.
  2. Every metric is scored against companies in the same sector, then ranked across all rated names.
  3. A name missing any factor gets no overall grade. Meridian leaves it blank rather than estimate it.
  4. Grades are rebuilt each morning and kept, so every change has a date.
Meridian's page for NVIDIA: a Meridian Score of 9.2 out of 10 and six factor grades, from Valuation 5.3 to Profitability 9.8.

Agora

In development

A social network for one campus at a time.

  1. Every member will verify a US university address.
  2. Posts, groups and student organizations will be visible only to members of the same campus.
  3. The feed will be newest first. Posts from your groups, friends and people you follow will move up, and a Latest view will show strict time order.
  4. We are building it now, and will publish how the feed is ordered before it opens.

About

Daedalus Data Labs builds and runs Meridian, and is building Agora. Both publish how they work: Meridian its grading method, and Agora, when it opens, the order of its feed. The name comes from Daedalus, the craftsman of Greek myth who built the labyrinth. The mark is drawn like one: an L and a D on the outside, with a second D inside, which spells DaeDaLus and Data Labs. Every stroke and every gap is the same width, and every cut is at 45 degrees.
