      Filed March 21, 2006



Dear Mr. Kaplan:

      We have reviewed your filings and have the following
comments.
Where indicated, we think you should revise your documents in
response
to these comments.  If you disagree, we will consider your
explanation
as to why our comment is inapplicable or a revision is
unnecessary.
Please be as detailed as necessary in your explanation.  In some
of
our comments, we may ask you to provide us with information so we
may
better understand your disclosure.  After reviewing this
information,
we may raise additional comments.

      Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We
look forward to working with you in these respects.  We welcome
any
questions you may have about our comments or any other aspect of
our
review.  Feel free to call us at the telephone numbers listed at
the
end of this letter.



General Comments
1. Please refer to the selling stockholder by name rather (Societe
Generale) than by the generic term "selling stockholder."  In
addition, please avoid using abbreviations such as "SGCSG,"
"SGAI,"
"SGAS" and "TMT."


Summary, page 1
2. Please revise the section entitled "Overview" to disclose
* disclose that you are a wholly owned subsidiary of Societe
Generale
and that Societe Generale has decided to liquidate its investment
in
Cowan by disposing of at least 88.8 percent, and possibly all, of
its
stock in connection with this offering; and
* that as part of the separation from Societe Generale you are
giving
management a fourteen percent interest in the company.

3. Please add a section in the summary summarizing your
relationship
with Societe Generale over the past eight years and summarizing
the
terms of the separation.  Please summarize the effects of the
separation on you, including the possible loss of business from
Societe Generale and its clients.

4. In the second sentence of the first paragraph, clarify the
meaning
of   "correct, non-consensus conclusions."  Likewise, clarify the
meaning of the sentence that follows.

5. Please explain on page 1 and page 3 how you will get the
resources
to support the growth strategy you have adopted.

6. Please revise the section entitled "Competitive Strengths," on
page
2, by deleting the following claims or providing us with objective
evidence to support them:
* you have a "leading position" in your target sectors;
* you are the "leading franchise" focused on your target growth
sectors; and
* you have "equity research leadership."

7. Please revise the section entitled "Market Opportunity and
Focus,"
on page 2, to reconcile your claims that your focus on three
particular sectors is a benefit with your statement on page 20
that
your dependence on these same sectors "caused our year over year
investment banking results to diverge somewhat from broader market
trends and volumes."
8. Please revise the section entitled "Cowen Group, Inc.," on page
4,
as follows:
* add the following caption to the second paragraph: "Cash
Distribution to Selling Shareholder;" and
* estimate the amount of the cash contribution.

9. Revise to define group equity here and in the notes to the
financial statements.

10. Revise to define the source of the cash distribution.  The
repos
in the balance sheet suggest that this may not be a cash
distribution
to the seller.


Capitalization, page 22

13. Expand the pro forma adjustments listed in Note 1 to reflect
the
reduction of interest income related to the transfer of cash into

escrow account to be utilized for the future payment, if any, of
certain litigation and related costs subject to indemnification by
Societe Generale since this interest income will be paid to the
selling stockholder.

14. You disclose that the company`s brokerage and clearance
expense is
expected to increase upon entering into a new commercial clearing
agreement prior to the closing of this offering, replacing the
company`s existing clearing agreement.  Please revise to provide a
pro
forma adjustment in the pro forma combined operating information
presented on page 24 and to provide a Note on page 26.
15. Please revise to apply your statutory/expected tax rate of 45%
resulting from the separation agreement on the face of the pro
forma

factors
relevant to the company on which management is concerned.

19. Please revise your discussion of you financial results from

Societe
Generale.  Please include analysis of the following:

Societe
Generale;
* the aggregate and particular additional costs that you will
incur as
a result of the separation sand going public including higher cost
of
capital and higher tax rate;
* the extent to which Societe Generale will be competing with you
and
the extent to which it has plans to compete with you;

services;

fees.

23. In the event that components of other revenue will decline as
a
result of the offering, please revise to add an adjustment to the
pro
forma combined financial statements.  We note the elimination of
income in pro forma adjustment number 2 appearing on page 26

product related to the Deferred Compensation Plan which will be
transferred to the selling stockholder in connection with this
offering.
