NAND flash economics compress to one metric: layers per die. Each additional cell layer spreads fixed manufacturing costs across more stored bits, and where a producer sits on that curve determines the cost floor for downstream storage hardware. SanDisk, the flash memory maker, communicated something to investors this week that the Investing Club identified as a positive signal for one of its portfolio positions.
The club publishes the Homestretch each weekday, timed for the market's final trading hour. This week's edition identified SanDisk's investor communication as favorable for the position it had most recently initiated.
