Many Xiaomi Corp. investors, who could only watch as the stock shed $14 billion in market value, are now able to join in on the selling. Expiring Wednesday is the six-month lockup period that followed the company\u2019s Hong Kong debut, during which some employees and cornerstone investors were banned from disposing of their allocated shares. It\u2019s been painful: Xiaomi has dropped to HK$10.50 from a listing price of HK$17, sinking another 5.4 percent Wednesday in early trading. More than 3 billion shares were unlocked, equal to about 19 percent of those outstanding, according to data compiled by Bloomberg. The lockup period for controlling shareholders - such as chairman and founder Lei Jun - was extended Wednesday for another 365 days, Xiaomi said in a statement. It was previously due to expire in July. Touted by bankers last year as China\u2019s answer to Apple Inc., Beijing-based Xiaomi sought a valuation that would have made it the most expensive smartphone maker in the world. The stock trades at 16 times projected 12-month earnings, less than half its July multiple. It\u2019s still 34 percent more expensive than Apple, which is reeling from its worst quarterly rout in more than a decade. To be sure, longer-term investors may want to hold on to Xiaomi\u2019s shares rather than dump them at a loss. Analysts on average still predict Xiaomi will rebound to its IPO price. Hedge funds have been increasing their bearish bets, with almost 30 million shares sold short Tuesday, the most since August. Xiaomi attracted the likes of China Mobile Ltd. and U.S. wireless-chip giant Qualcomm Inc. as cornerstone investors last year.
