There are many lock out periods where the C Suite, Directors and other management teams and departments cannot buy/sell stock. Generally a few weeks before close of period to a few days after filing SEC reports. I would not expect any news of insider activity until after finances are reported for 2019. I believe the exception to this, is if Stock Options have a mandatory issuance date during this time period. They can be issued, but not sold until after the lockout period. If I am wrong on this point, I will listen to correction.
