Stocks of Taiwanese pattern sapphire substrate (PSS) providers, including Crystalwise, Rigitech Microelectronics, and Acme Electronics, lately witness a noticeable hike.

Following the launch of the sapphire covered Apple Watch, Tawanese sapphire makers share value have soared over the last week. As the LED industry enters a peak season, sapphire industry shares value have reached new record high, reported Apple Daily.

Wearable devices have stolen the show at the Mobile World Congress (MWC) in Barcelona, according to Chinese-language United Evening News. Companies including Samsung, LG, Sony, and Huawei Device have all showcased their wearable designs at the show. Increasing investment from manufacturers is leading to a rise in sapphire material applications. Sapphire material prices began to rise at an average of 5-7% during 1Q14, which stimulated listed company Crystalwise Technology and ACME Electronics Corp. rising stock prices on Feb. 25, 2014. This in turn led to LED stocks strong growth.

LED upstream key material PSS is in short supply with demands unable to be met. With supply unable to meet demands from LED manufacturers last year, production capacity is lacking by 50 percent, according to Economic Daily News. This had lead to a rise in price of around 5 percent for sapphire ingot, polished wafers, and PSS in March. Manufacturers including Crystalwise, Ridgetech, Aceplux Optotech, and Crystal Applied Technology are anticipated to benefit. PSS industry insiders are optimistic towards March operations.
