Allen Winkler, CFA, recently had lunch with Kim Thompson, a former professor of his, who told him of a new valuation model she had developed. Winkler recreated Thompson's model with some revisions and back-tested it using data provided by Standard & Poor's (S&P) with impressive results. Winkler's firm launches a mutual fund based on the revised model, and Winkler provides a discussion of the principles underlying the model and the test results. Is Winkler required to credit Thompson for having developed the model and S&P as the source of the data? A: Both of these sources must be cited. B: Neither of these sources must be cited. C: Only one of these sources must be cited.
