Melco Crown Entertainment Ltd. stocks dropped the most in seven weeks yesterday.

According to Bloomberg, Melco slid as much as 5.6 percent to HK$28.10, the biggest intraday drop since mid-December.

“Melco Crown is losing market share to competitors; its share in January is expected to drop by up to 2 percentage points on a monthly basis which may explain why it is leading the decline,” said Victor Yip, a Hong Kong-based analyst at UOB Kay Hian Ltd.

Wynn Macau Ltd. sank 4.8 percent to HK$19.7 and SJM Holdings Ltd dropped 3.3 percent to HK$13.32. Galaxy Entertainment Group also dropped 1.5 percent to HK$16.80.
