Sandisk's Sharp Drop: What It Means for South Africa
Sandisk’s 12% plunge after a Chinese memory chip IPO signals rising competition risks, seen through a Rand lens as a pressure test for tech margins.
Sandisk’s 11.7% drop after the Chinese CXMT IPO isn’t just a blip. The debut of a massive Chinese DRAM player, jumping 466%, has investors worried about a spillover into NAND flash memory, where Sandisk earns fat 70% profit margins. For local investors, this matters because it highlights how global tech supply chains and profitability pressures could eventually seep into South African proxies like Naspers or Prosus, which hold significant stakes in global tech assets. If China forces a price war or innovation race in memory chips, the earnings growth story for these JSE giants could be dented. Meanwhile, the USD/ZAR should remain sensitive—pressure on tech earnings abroad can weaken emerging market appetite and the rand. I’d watch Naspers and Prosus closely but hold off on fresh buys until the dust settles. The view could be wrong if China sticks to DRAM and leaves NAND mostly alone, preserving Sandisk’s margins. this is just my opinion and not financial advice
Wait on buying Naspers and Prosus until we see clearer signs on the China NAND threat; consider hedging rand exposure if tech volatility spikes.

- Prosus

Sandisk stock dropped 11.7% on Monday following the massive IPO of Chinese DRAM chipmaker CXMT, which debuted on the Shanghai Stock Exchange with a $487 billion market cap and surged 466% on its first day. While Sandisk specializes in NAND flash memory rather than DRAM, investors fear China may soon enter the NAND market, threatening Sandisk's 70% operating profit margins.
