• Alibaba and Tencent remain stalwarts among China's technology stocks despite fears of increasing regulation, says Jackson Wong of Amber Hill Capital.
• Chinese tech stocks in Hong Kong have lagged relative to other sectors so far this year. In the first quarter, no tech stocks were in the 10 top constituents of the city's benchmark Hang Seng index.
• Tencent shares rose about 8% in the first quarter of the year. Alibaba, on the other hand, saw its Hong Kong-listed shares drop more than 5% in the same period.

Alibaba and Tencent remain China's top technology stocks — even as Beijing continues to ramp up regulatory pressure on its big internet firms, says Jackson Wong of Amber Hill Capital.

"At this point, I can't see any other stocks that can challenge their positions in China," Wong, director of asset management at Amber Hill, told CNBC's "Street Signs Asia" on Thursday.

Alibaba and Tencent "are still the benchmark" among China's tech stocks, he said. Wong's family and Amber Hill both own shares in the two companies.

His comments come as Chinese tech stocks in Hong Kong lagged the other sectors so far this year.

The top 10 constituents of the Hang Seng index did not include a single tech stock at the end of the first quarter, according to a CNBC analysis using data from Refinitiv Eikon.

What's dragging down tech shares?

A range of factors have contributed to the comparatively poorer performance of the tech sector, which makes up more than 42% of Hong Kong's benchmark index.

One reason is that bond yields are rising — and that hurts growth stocks like techs because they reduce the relative value of future earnings.

Another concern is delisting threats from the U.S. Chinese tech shares that are also listed in the U.S. have taken a beating this year, amid fears that a new U.S. law could stop the trading of securities that fall foul of Securities and Exchange Commission rules.

Finally, China's regulatory crackdown on the sector has also spooked investors.

The business empire of Alibaba's founder, Jack Ma, suffered a huge blow last year when China pulled the plug on Ant Group's initial public offering, and suspended what would have been the largest IPO in history. Ma is the co-founder and controller of Ant Group.

Alibaba does not appear to be the only internet titan that's being targeted. Reuters reported in March that Tencent's founder Pony Ma met with Chinese antitrust officials earlier last month.

Still, Tencent shares rose about 8% in the first quarter of the year. Alibaba, on the other hand, saw its Hong Kong-listed shares drop more than 5% in the same period.

Both firms got off to a positive start in the second quarter. Tencent's stock soared 7.21% while Alibaba shares in Hong Kong jumped 2.55% on Thursday — the last trading day before the long holiday. Trading starts again on April 7.

Challenges ahead

Looking ahead, Wong acknowledged that political headwinds and potential regulatory rules ahead could "really damage" the profit outlook for the two internet giants that dominate China's tech space.

However, he expects "some kind of compromise" to be eventually reached on the regulatory front.

"Going forward, their valuations might not be, you know, 50 or 60 times of earnings. Still ... they're trading at around 30 times of earnings and they are at a very good position in China," Wong said.

He was referring to price-to-earnings (P/E) ratio — a measure of a company's stock price relative to its earnings. A high P/E ratio could indicate an expensive stock price compared to its earnings.

Alibaba's Hong Kong-listed stock had a P/E ratio of 26.34 while Tencent's P/E ratio was 33.36, according to data from Refinitiv Eikon.

In comparison, some U.S. tech stocks have much loftier valuations. Amazon and Netflix have P/E ratios of 75.71 and 91.6, respectively, while Tesla's stands at more than 1,000.

Meanwhile, Apple and Facebook share similar valuations with the Chinese tech giants. The two firms' P/E ratios were at 33.25 and 29.61 respectively.
