Does the following thing they make you acknowledge mean you can’t use this to pick stocks?

“It is unlawful to use the information contained in these Financial Disclosure Statements for (A) any unlawful purpose, (B) any commercial purpose, other than by news and communications media for dissemination to the general public, (C) determining or establishing the credit rating of any individual, or (D) use, directly or indirectly, in the solicitation of money for any political, charitable, or other purpose. See 5 U.S.C. app. § 105(c)(1),(2). In conformity with 2 U.S.C. § 104e(b)(3), certain personally identifiable information in these reports, not required to be disclosed, has been redacted.”

It definitely doesn't fall under (C) and (D). I'd have to stare harder at insider trading laws, but probably doesn't fall under (A) either. (B) might prohibit you from building an index fund based on it, but I think you should be able to do the stock picking yourself.
