Last Friday reporter Tricia Duryee wrote a piece that appeared in and that noted —

“… Amazon stock hit a 52-week high [on Jan. 25] in anticipation of a strong earnings report on Tuesday, boosted by a spike in holiday spending. … According to comScore’s final tally for the November-December shopping season, online spending in the U.S. totaled $42.3 billion, which was a 14 percent increase over 2011, but fell short of its expectations. …”


The abstract for a 1996 academic article noted that —

“We study the implied volatility behavior of call options around scheduled news announcement days. Implied volatilities increase significantly during the pre-event period and reach a maximum on the eve of the news announcement. After the news release, implied volatility drops sharply and gradually moves back to its long-run level. Only on the event date are movements in the price of the underlying significantly larger than expected. These results confirm the theoretical results of Merton (1973).”
