As a trader, when the stock moves afterhours, I still like to see it happen even though I know I don't trade it. So what if she made all those calls. Perhaps she was just concerned about her friend. Also, if I read news that some CEO is selling stock on the fly or my broker tells me that, I don't assume it is inside information. CEOs sell all the time, and it might be public information if the CEO announces it to the world.
Also, there is a mosaic theory that applies to inside information. If there are rumors that Coke might cut a deal with McDonalds, and if I see the Coke CEO having lunch with McD but I don't hear the conversation, that I can trade on my presumption that the deal is going on, and that is not inside information.
Perhaps the broker ASSUMED that the CEO was selling, and passed that rumor to Steward. First of all, it is hard to tell if this is not so, because we don't have the exact conversation records am I wrong? How many times do we call a top with conviction. It doesn't mean that it is inside information if he doesn't know for sure.
Even if it can be proven that the broker is at fault, showing that Steward knew this is further tenuous.
For that reason, the inside trading charge is rightfully dropped. And if Steward gets convicted, I for one would not feel free to say a single word to prosecuters. Can you imagine if all CEOs and public figures fear talking to prosecuters without their lawyers because anything they say (even saying they are innocent) may be a crime that puts them in jail for 30 years even if they are charged (although not in this case) for something that is less damaging?
