Exhibit 24.2

NEW YORK POWER OF ATTORNEY

KNOW ALL BY THESE
PRESENTS, that each person whose signature appears below hereby constitutes and appoints RICHARD J. HENDRIX and BRADLEY J. WRIGHT, and each of them severally, as his true and lawful attorney-in-fact and agent, each acting along with full power of
substitution and resubstitution, for him and in his name, place and stead, in any and all capacities, to sign any or all amendments and exhibits to the Annual Report on Form 10-K for the fiscal year ended December 31, 2009 of FBR Capital
Markets Corporation, and to file the same, with all exhibits thereto, and any other documents in connection therewith, with the Securities and Exchange Commission, granting unto said attorney-in-fact and agent full power and authority to do and
perform each and every act and thing requisite and necessary to be done in and about the premises, as fully to all intents and purposes as he might or could do in person, hereby ratifying and confirming all that said attorney-in-fact and agent, or
his substitute or substitutes, may lawfully do or cause to be done by virtue thereof.

This Power of Attorney may be executed
in counterparts and all such duly executed counterparts shall together constitute the same instrument. This Power of Attorney shall not revoke any powers of attorney previously executed by the undersigned principal. This Power of Attorney shall not
be revoked by any subsequent power of attorney that the undersigned principal may execute, unless such subsequent power of attorney specifically provides that it revokes this Power of Attorney by referring to the date of the undersigned
principals execution of this Power of Attorney.

Anything to the contrary herein notwithstanding, this Power of Attorney
DOES NOT grant the attorneys-in-fact authority to spend the undersigned principals money or sell or dispose of the undersigned principals property during the undersigned principals lifetime.

CAUTION TO THE PRINCIPAL: Your Power of Attorney is an important document. As the principal, you give the person whom you choose
(your agent) authority to spend your money and sell or dispose of your property during your lifetime without telling you. You do not lose your authority to act even though you have given your agent similar authority.

When your agent exercises this authority, he or she must act according to any instructions you have provided or, where there are no specific
instructions, in your best interest. Important Information for the Agent at the end of this document describes your agents responsibilities.

Your agent can act on your behalf only after signing the Power of Attorney before a notary public.

You can request information from your agent at any time. If you are revoking a prior Power of Attorney by executing this Power of Attorney, you should provide written notice of the revocation to your
prior agent(s) and to the financial institutions where your accounts are located.

You can revoke or terminate your Power of
Attorney at any time for any reason as long as you are of sound mind. If you are no longer of sound mind, a court can remove an agent for acting improperly.

Your agent cannot make health care decisions for you. You may execute a Health Care Proxy to do this.

The law governing Powers of Attorney is contained in the New York General Obligations Law, Article 5, Title 15. This law is available at a law library, or online through the New York State Senate or
Assembly websites, www.senate.state.ny.us or www.assembly.state.ny.us.

If there is anything about this document that you do
not understand, you should ask a lawyer of your own choosing to explain it to you.

IN WITNESS WHEREOF, each of the
undersigned principals has executed this instrument on the date indicated opposite his name.

IMPORTANT INFORMATION FOR THE AGENT: When you accept the authority granted under this Power
of Attorney, a special legal relationship is created between you and the principal. This relationship imposes on you legal responsibilities that continue until you resign or the Power of Attorney is terminated or revoked. You must:



|(1) | act according to any instructions from the principal, or, where there are no instructions, in the principals best interest;
|--- | ----------------------------------------------------------------------------------------------------------------------------



|(2) | avoid conflicts that would impair your ability to act in the principals best interest;
|--- | ---------------------------------------------------------------------------------------



|(3) | keep the principals property separate and distinct from any assets you own or control, unless otherwise permitted by law;
|--- | --------------------------------------------------------------------------------------------------------------------------



|(4) | keep a record or all receipts, payments, and transactions conducted for the principal; and
|--- | ------------------------------------------------------------------------------------------



|(5) | disclose your identity as an agent whenever you act for the principal by writing or printing the principals name and signing your own name as agent in
either of the following manner: (Principals Name) by (Your Signature) as Agent, or (your signature) as Agent for (Principals Name).
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

You may not use the principals assets to benefit yourself or give major gifts to yourself or anyone else unless the principal has specifically granted you that authority in this Power of Attorney or
in a Statutory Major Gifts Rider attached to this Power of Attorney. If you have that authority, you must act according to any instructions of the principal or, where there are no such instructions, in the principals best interest. You may
resign by giving written notice to the principal and to any co-agent, successor agent, monitor if one has been named in this document, or the principals guardian if one has been appointed. If there is anything about this document or your
responsibilities that you do not understand, you should seek legal advice.

Liability of agent:

The meaning of the authority given to you is defined in New Yorks General Obligations Law, Article 5, Title 15. If it is found that
you have violated the law or acted outside the authority granted to you in the Power of Attorney, you may be liable under the law for your violation.

IN WITNESS WHEREOF, each of the undersigned agents has executed this instrument on the date indicated opposite his name.
