Shares of Hong Kong airline Cathay Pacific rebounded on Wednesday.
Still, "much uncertainty" remains ahead in the market, according to Luya You, analyst for transportation research at Bocom International.
"We believe ... the most prudent way to treat the stock right now is to downgrade to neutral," You — who disclosed ownership in Cathay Pacific stock — told CNBC's "Squawk Box" on Wednesday. "It's very, very hard for us to know what's going to happen in the next upcoming days or even upcoming weeks simply because right now Cathay Pacific is unfortunately stuck in a very, very, very tough place."
Shares of Cathay Pacific jumped 2.83% on Wednesday.

Cathay in the spotlight amid protests
You's comments came as Hong Kong continues to be rocked by protests that have lasted for weeks and have seen outbursts of violence. Recent rounds have left operations at the city's airport disrupted for two days.
For its part, Cathay Pacific has come under increased scrutiny from Beijing, with the Chinese aviation regulatory body issuing a "major aviation safety risk warning" to the airline last week. The Civil Aviation Authority said that "on multiple occasions," Cathay's flight personnel have participated in "violent assault," according to CNBC's translation.
"The incidents pose a serious threat to aviation safety, causing adverse social impact and as a result is increasing inbound aviation safety threats from Hong Kong to the mainland," it said.
It also ordered the carrier to provide identification information for its crew on mainland-bound flights, and said that crew members that do not receive the authority's approval won't be allowed into its airspace, including on flights bound for other destinations.
Asked if other airlines could benefit from the misfortunes of Cathay Pacific, You said it was possible but "it's a little bit too early" at the moment, as the Chinese aviation authority was "still waiting" to see the carrier's response.
"If things do significantly ... deteriorate then potentially yes, you know, the other airlines such as Air China, China Southern, even foreign airlines at Hong Kong International Airport could benefit from any displaced demand that goes from Cathay to anywhere else," she said.
'Very critical period'
Looking ahead, You said it was "very hard to say" how Cathay Pacific was likely to respond further to the current situation.
"Everybody's waiting to see their official response," You said. "They've already issued their verbal response, their verbal agreement to China's new standards but we've yet to see really a lot of mass actions." She added that it is a "very critical period" for Cathay Pacific as investors wait to see if China "agrees" that the firm has taken sufficient measures.
If Beijing disagrees, then there could be more restrictions for Cathay Pacific, she said, adding that it would be "absolutely catastrophic" for the airline if it were to lose certain access or a "very, very large part of their market."
So far, Cathay Pacific has suspended two pilots, fired two ground staff and issued a warning email to its employees. The airline's top shareholder and manager, Swire Pacific, has also voiced support for China and vowed to follow China's aviation regulations.
