Chapman and Cutler LLP 111 West Monroe Street Chicago, Illinois 60603 March 5, 2013 Mr. Edward Bartz Division of Investment Management Securities and Exchange Commission 100 F Street, N.E. Washington, DC 20549 Re: Guggenheim Defined Portfolios, Series 1016 All Cap Growth Strategy Portfolio, Series 1 File Nos. 333-186317 and 811-03763 ------------------------------------------------------------------------------- Dear Mr. Bartz: This letter is in response to your comments given during a telephone conversation between you and our office regarding the registration statement on Form S-6 for Guggenheim Defined Portfolios, Series 1016, filed on January 30, 2013 with the Securities and Exchange Commission (the "Commission"). The registration statement offers the All Cap Growth Strategy Portfolio, Series 1 (the "Trust"). This letter serves to respond to your comments. PROSPECTUS Investment Summary - Security Selection - Security Selection Rules 1. Initial Universe - The clause at the end of "Investment Summary - Security Selection - Security Selection Rules - Initial Universe" that states "with their index weights scaled by 50%, 25% and 25%, respectively" is unclear. Please explain or elaborate on this clause. Response: The clause refers to the final sector weights of the Trust portfolio. The clause has been deleted and the first bullet of the second paragraph under "Investment Summary - Security Selection - Security Selection Rules - Selection" has been revised to state: "Weight in all Global Industry Classification Standard sectors must be within +/- 5% of the initial universe, where the securities in the initial universe originating from the S&P 500 Pure Growth Index are assigned 50% of their index weight, and securities originating from the S&P MidCap 400 Pure Growth and the S&P SmallCap 600 Pure Growth Indices are assigned 25% of their index weight. For example, if the Industrials sector comprised of 20% of each of the indices, then this sector would be given a weight of 10%, 5% and 5% from the S&P 500 Pure Growth Index, S&P MidCap 400 Pure Growth Index and the S&P SmallCap 600 Pure Growth Index, respectively. As a result, 15%-25% of the trust's portfolio would be from the Industrials sector (20% +/- 5%)." 2. Rank on Fundamentals - Please disclose the source for the standard deviation of daily returns for the trailing year referenced in the second bullet. Response: The disclosure has been revised as requested. Investment Summary - Hypothetical Performance Information 3.
