It that what you garnered from the article? Lol. Perhaps you may wish to conduct further case study. I would strongly recommend consulting competent counsel prior to trading based upon material non public information. Perhaps reading the statute as it is written, paying particular attention the "on the basis of", may be of assistance.
The SEC adopted new Rules 10b5-1 and 10b5-2 to resolve two insider trading issues where the courts have disagreed. Rule 10b5-1 provides that a person trades on the basis of material nonpublic information if a trader is "aware" of the material nonpublic information when making the purchase or sale.
I would STRONGLY urge investors to consult an attorney who specializes in securities law who can make a determination of whether their trading activity is likely to result in that investor running afoul of the law.
