China is cutting its quarantine time for international travelers to 10 days, which is lending support to sectors like casino stocks.
Morgan Stanley just published its Global Exposure Guide, which tracks revenue and cost exposure by region.
"While China is a very important source of revenue for some companies like the casinos/hotels/tech companies the median company in our coverage derives 0% of revenue from China," strategist Michelle Weaver and team wrote in the report.
"The maximum exposures also vary substantially by sector," Weaver said. Four sectors - Consumer Discretionary (XLY), Info Tech (NYSEARCA:XLK), Industrials (XLI) and Healthcare (XLV) - have maximum exposure higher than 30%. Three sectors - Materials (XLB), Energy (XLE) and Consumer Staples (XLP) - have maximum exposure in the high teens. No Utility (XLU) has exposure to China.
"This high degree of variation makes it very important to examine exposure at the stock level."
"The Tech sector has the highest aggregate exposure at 12% and is driven by Semis at 28% and Tech Hardware at 13%," Weaver added. "Consumer Discretionary and Industrials have the next highest exposure at 5% and 4%, respectively. Consumer Discretionary's exposure is driven by the Autos (16%) and Consumer Durables & Apparel (12%) industry groups."
