How does it work?

Composer acts as a layer on top of brokerages.
Create your symphony from a set of simple but infinitely combinable building blocks.
No-code,
visual editing.

Highlights

Three stock picks: ICLN, FSLR, TSLA.Three stock picks: ICLN, FSLR, TSLA.
Then, apply weighting.
  • No more ad-hoc allocations or error-prone, tedious spreadsheets.
  • You can specify the weights, or choose from a set of weighting functions like Market Cap or Inverse Volatility.
The three assets, ICLN, FSLR, TSLA, with Specified Weighting applied as follows: 70%, 20% and 10%.The three assets, ICLN, FSLR, TSLA, with Specified Weighting applied as follows: 70%, 20% and 10%.
