Sandisk ( $SNDK+WL -0.54% ) stock got off to a great start Tuesday, bouncing back nearly 5% after yesterday's China-inspired sell-off -- but it didn't last. Shares of the NAND flash memory-maker reversed course later in the morning, even dipping into the red. ET, Sandisk stock is still up from yesterday's close -- but only 1%. One imagines the stock is still being dogged by worries that, to mitigate the effects of global memory shortage, the Trump Administration will permit Apple -- and potentially others -- to purchase memory chips from Chinese suppliers ChangXin Memory Technologies (CXMT) and Yangtze Memory Technologies Corp (YMTC). CXMT recently conducted an IPO in Shanghai that added $8.6 billion to its war chest amid plans to increase production of DRAM chips and begin producing high-bandwidth memory for the artificial intelligence market.

Semiconductor trade policy
Sandisk stock rose at first but then fell back down because the US government might let companies buy memory chips from China instead. Investors are worried this extra competition will hurt sales and profits for memory chip makers.
What changed
Sandisk shares reversed an early 5% gain following news about potential U.S. waivers for Chinese memory suppliers like CXMT and YMTC.
Who wins / who loses
Chinese memory makers and device assemblers like Apple could benefit, while traditional memory chip suppliers like Sandisk face margin pressure.
Time horizon
Think in terms of the next few weeks.
