EXHIBIT 12.3 Chip stock volatility before and after earnings reports. Source : Chart courtesy of iVolatility.com In mid-July, Susie did some digging to learn that earnings were to be announced on July 24, after the close. She was careful to observe the classic rush and crush that occurred to varying degrees around the last three earnings announcements, in October, January, and April. In each case, IV firmed up before earnings only to get crushed after the report. In mid-to-late July, she watched as IV climbed to the mid-30s (the rush) just before earnings. As the stock lay in wait for the report, trading came to a proverbial screeching halt, sending realized volatility lower, to about 13 percent. Susie waited for the end of the day just before the report to make her move. Before the closing bell, the stock was at $50. Susie sold 20 one- month 50-strike calls at 2.10 (a 35 volatility) and bought 1,100 shares of the underlying stock at $50 to become delta neutral.
