Here are some of the companies the Yahoo Finance team will be watching today. Intercontinental Hotels Group ( IHG ), the owner of Holiday Inn hotels, is blaming unrest in Hong Kong for lower bookings and a nearly 1% drop in overall revenue. It reported a 6% slide in revenue per available room in Greater China, and in Hong Kong, revenue plummeted 36%. IHG isn't the only company feeling the pressure. Hilton Worldwide ( HLT ) and AccorHotels both warned investors that the U.S.-China trade war is hurting revenue. SmileDirectClub ( SDC ) has filed a lawsuit against the California Dental Board. The suit claims that dentists had an investigator raid SmileDirectClub shops across California in an attempt to stifle competition. A source tells Yahoo Finance no damage was done to SmileDirectClub stores in the raid, but that the investigator allegedly harassed and intimidated employees with questions.
