What the score is reading for WDC
At the Friday 2 October close, WDC scored 9, 34th of the 34 names here, and not one of the six inputs sat above the board's median. The score was the sum of six unremarkable readings rather than anything pulling it in either direction — which is a finding about WDC that session, not a gap in the data. Pulling the other way was momentum at -12.0 — the day's move against the previous close.
Across the 16 sessions recorded since 3 September, WDC has scored between 9 and 67, and that 9 sits near the bottom of that range. Net across the window it is down 23 points, and the largest single-session move was a fall of 43 points on 2 October.

Common questions
Why do hard drives still matter in an AI datacentre?
Training datasets are enormous and mostly cold. Bulk capacity remains far cheaper per terabyte on spinning media than on flash.
What is Western Digital's market sentiment score right now?
WDC currently scores 9 out of 100, which reads as frozen. The score combines six weighted, price-based inputs: momentum, relative strength against the complex, trend against its moving averages, volume, volatility and drawdown from the 52-week high. The full breakdown is shown above.
Where does WDC sit in the AI supply chain?
Western Digital is grouped under memory & storage. High-bandwidth memory and the storage beneath it. Memory bandwidth, not compute, is what most often limits AI training throughput.
