SanDisk’s stock had a wild ride in 2025, rocketing nearly 7,000 percent to over $2,350 before crashing roughly 57 percent by late July, plummeting back near $1,000. This rollercoaster sent its relative strength index, or RSI, swinging from an unprecedented overbought level north of 99 in mid-June to its lowest oversold reading since early March.
Such extreme moves suggest the recent sell-off might be winding down. When the RSI dropped this low in early 2025, the stock didn’t bounce immediately but soon launched into its historic climb from $37 to more than $2,300. Even after the decline, SanDisk’s shares still sit more than 2,600 percent above the price at its spinoff from Western Digital.
But a low RSI alone isn’t a free pass to buy. SanDisk’s growth is closely tied to artificial intelligence, and investor skepticism has been rising. The expanding AI sector has demanded massive investment without clear returns, shaking confidence across major tech stocks this year. Microsoft’s recent earnings offered a glimmer of hope for a tech rebound, yet Meta's report cast some doubts. Meanwhile, volatility in South Korea’s tech-heavy market adds another layer of uncertainty for companies like SanDisk.
