The evidence strongly supports the truthfulness of the statement. Multiple high-authority sources confirm a significant drop in the Dow Jones Industrial Average. One news report specifies a precise fall of 797.60 points, while another corroborates this by stating a loss of "approximately 800 points." A drop of nearly 800 points can be reasonably described as "approximately 700 points," as it captures the general magnitude of the event, even if it is not the most precise approximation. The presence of financial data portals among the sources, which would contain the raw data to verify this drop, further strengthens the claim. The only source that does not support the statement is irrelevant, as it discusses a historical event from 1929 where point drops of this size were not possible. There are no contradictions among the relevant, credible sources.
