After hours trades are often posted at brokerages as a means of manipulating people. Called "painting," the idea is to install the uh-oh factor in the hopes of enabling the devious individual to manipulate his way into turning a stock's market sour at the opening the morning after. This might bring less savvy investors to sell shares on the cheap out of fear.
After seeing your post, I went to NASD as I usually do in the after hours and the price drop you mentioned wasn't showing. I checked at Ameritrade and it wasn't there either. This morning=---in the premarket session, shares were actually up 14 cents.
After hours postings are not to be trusted. However, if you're looking for an edge prior to taking a position, you might be on the right track. I'd urge caution, however.
