Oh yeah Henry? Let's look at the timeline:
October 16th-Enron issues public restatement of earnings indicating huge losses
October 26th-Enron contacts Evans
October 26th-Enron contacts Greenspan
October 28th-Enron Contacts O'Neill
October 29th-401k lockdown
November 12-Lockdown lifted
Now you tell me. The losses had already been publically announced and the stocks began to fall on October 16th. Just what was supposed to be done?
