Priceline Group

- Nearest Resistance: $1,250
- Nearest Support: $1,100
- Catalyst: Q1 Earnings
Wednesday is shaping up to be a rough session for shares of $60 billion online travel company Priceline Group (PCLN - Get Report) . Priceline's shares are down nearly 10% as I write this afternoon, selling off following the firm's first-quarter earnings results. Priceline actually beat estimates for the quarter, generating profits of $10.54 per share, versus the $9.66 in earnings that analysts were expecting. That said, the firm's forecasts for the second quarter missed the mark, and that's what's driving the selling in Priceline this afternoon.

Technically speaking, Priceline's selling today is pretty significant. Shares are violating support at $1,250 today, a breakdown that's triggering the double top pattern that's been forming in shares of Priceline since the end of February. From here, support at $1,100 looks like the next potential pocket of buying pressure for shares on the way down.
