Pakistan's stocks rallying since mid-December

Pakistan's stocks have been on a tear since mid-December and, according to financial experts CNBC spoke to, a combination of factors are pushing up the Karachi Stock Exchange (KSE).

The country's benchmark exchange is currently trading up 16.7 percent since December 19, the start of a rally ostensibly linked to the central bank's decision to devalue the Pakistani rupee a few days earlier. But the State Bank of Pakistan's decision to withdraw support for its currency in a bid to encourage economic growth could only be part of the story.

"The recent sharp surge in the KSE 100 stock index is first and foremost a natural correction following a sizeable sell-off over the second half of 2017," Michael Henderson, chief economist at risk consultancy Verisk Maplecroft, told CNBC via e-mail.

Henderson placed Pakistan's rally amid broader risk on sentiment for emerging markets, pointing out that: "Emerging economies are witnessing strong growth across the board and Pakistan is no exception to the rule - GDP growth is currently in a sweet spot of around 5 percent per annum."

But, substantial foreign investment from China could also be playing a role. The superpower is expected to pump $60 billion into its smaller regional neighbor as part of its Belt and Road Initiative, a massive infrastructure building plan to resurrect ancient trading routes across Asia and beyond. "Investors may be getting in early in anticipation of big future gains," Henderson said.

The Pakistan Stock Exchange, the company that operates financial markets in the country, is itself 40 percent owned by a Chinese consortium, Reuters reported a year ago. Pakistan's rallying stocks come ahead of a politically turbulent background. Earlier in January, news broke that the U.S. was cutting $2 billion of aid to the country, accusing it of refusing to combat terrorism.

In addition, former Prime Minister Nawaz Sharif was booted from office in July last year following allegations of corruption. No Pakistani prime minister has completed a full term in office since the country's formation in 1947.
