'Fair' release of market-moving information would be a good place to use true 'broadcast' technology: radio waves, rather than broadcast-like network pushes. Potentially, also, an encrypted full-length report could be pre-released. Only after enough time for the ciphertext to be widely replicated to all interested parties would the short decryption key be radio-broadcast.
