Where does kennedy give a periodic statement in his speech

Kennedy does give a periodic statement in his speech at the beginning.

We observe today not a victory of party but a celebration of freedom--symbolizing an end as well as a beginning--signifying renewal as well as change.

A periodic sentence is a complex sentence in which the main clause, or main point, occurs at the end of the sentence instead of the beginning. In the traditional grammatical approach to sentence structure, a subject and predicate occur at the beginning of the sentence forming an independent clause. This clause expresses a complete thought and can stand on its own as a simple sentence.

In traditional complex sentence structure, the independent clause precedes the dependent clause, a group of words that offer additional information but do not form a complete sentence. Periodic sentences utilize complex sentence structure but invert it by placing the dependent clause(s) in front of the main independent clause.
