Charles Schwab (SCHW) is up 22 cents to $17 and the July/Aug 18 call spread trades 10000X. Looks like buying-to-close July and selling-to-open August, perhaps part of a buy-write strategy as 400K Schwab shares also traded at 10:12. Implied volatility is moving up, to 41.5 from about 40 late Thursday. No news today. Earnings due out July 13, before the July expiration.
