What is Proprietary Trading & Who are the Major Players?

Tuesday, November 10th, 2009

Jane Street Logo


What is proprietary trading?

Proprietary trading firms are usually limited partnerships that put  their own capital to work in the markets, rather than the capital of their clients.  Some of these firms also function as market makers, or liquidity providers to the capital markets.  Prop trading firms are different than hedge funds, which generate returns based on their fund size and benchmark performance.  In terms of compensation, prop trading firms often pay a base salary and a very lucrative performance bonus.  Turnover, however, is rather high at these firms, since these firms do not often tolerate shoddy performance.  In addition, newer firms often require a contribution of capital from traders who wish to join, from about $10-20,000.  In return, these firms often offer substantial leverage and training.  Many times, the training is well worth the experience if it is given for free.  Aspiring traders though need to be wary of firms that charge excessively for training.
