AI Multi-Horizon Analysis
No intraday data supplied; wide session range and elevated volume prevent directional conviction.
Price below 20-/26-/50-day averages, negative MACD, and heavy insider selling pressure dominate near-term bias.
Robust multi-period FCF growth (599M→3.51B), operating-margin expansion, and debt reduction support structural improvement despite recent liquidity dip.
Strong multi-period FCF and operating-margin expansion offset by recent insider selling, weakening liquidity metrics, and price below short-term averages.
Detailed AI Fundamental Analysis
Business Snapshot
- Western Digital Corp. (NASDAQ: WDC) is a US-listed common stock. The payload does not provide a sector, industry description, product mix, valuation multiples, earnings guidance, or analyst targets.
- The current price is $441.36 in pre-market trading. The reported session range is unusually wide: $151.42–$799.87.
- Over the supplied 200 daily bars, WDC rose from an opening price of $167.00 to $441.36, a 164.29% increase, but the current price remains well below the reported high of $799.87.
- The latest annual-period figures show $12.919 billion of revenue, $4.453 billion of operating income, $9.424 billion of net income, and $3.511 billion of free cash flow. Because the latest balance-sheet and income-statement period is a 10-K while the other entries are 10-Q periods, direct quarter-to-quarter comparisons should be treated cautiously.
Financial Trends
- Revenue: Reported revenue increased from $2.818 billion on 2025-10-03 to $3.017 billion on 2026-01-02, up $199 million / 7.1%. It then rose to $3.337 billion on 2026-04-03, up $320 million / 10.6%. The latest 10-K reports $12.919 billion, up $9.582 billion versus the preceding reported period, but this is not directly comparable to the quarterly figures because it is an annual filing.
- Gross margin: Gross margin improved from 43.54% to 45.74% between the oldest and next period, then to 50.22% in the 2026-04-03 period. It subsequently eased to 48.85% in the latest 10-K, a 1.37 percentage-point decline from 50.22%, while remaining 5.31 points above the oldest reported margin.
- Operating margin: Operating margin expanded from 28.11% to 30.10%, then to 35.66%. It moderated to 34.47% in the latest period, down 1.19 points from the prior reported period but still 6.36 points above the four-period-ago level.
- Net margin: Net margin rose from 41.94% to 61.05%, then to 96.04%, before falling to 72.95% in the latest period. The latest margin is down 23.09 points from the preceding reported period but remains 31.01 points above the oldest period. The unusually high latest-period net margin relative to operating margin suggests that net income may include items not visible in the operating-income line; the payload does not identify those items.
- Free cash flow: FCF accelerated from $599 million to $1.252 billion, then $2.230 billion, and finally $3.511 billion. The latest figure increased $1.281 billion / 57.4% from the prior reported period and $2.912 billion / 486.1% from the oldest period.
- Operating cash flow: Cash from operations followed the same improving pattern: $672 million → $1.417 billion → $2.540 billion → $3.929 billion. The latest value is up $1.389 billion / 54.7% from the preceding period and $3.257 billion / 484.7% from four periods ago.
- Capital expenditures: Capex increased from $73 million to $165 million, $310 million, and $418 million. Investment is rising alongside cash generation, while FCF has still expanded substantially.
- Assets and liquidity: Total assets moved from $14.359 billion to $15.611 billion and $15.045 billion, then declined to $13.861 billion. Current assets fell from $7.531 billion in the 2026-01-02 period to $5.634 billion latest. The current ratio improved from 1.21 to 1.45 and 1.49, then declined to 1.33.
- Debt and equity: Long-term debt declined from $2.457 billion to $2.429 billion, then was reported at $0 in the two latest periods. Total liabilities fell from $8.242 billion to $8.271 billion, then $5.365 billion and $4.997 billion. Shareholders’ equity increased from $5.888 billion to $7.111 billion, $9.680 billion, before declining to $8.864 billion latest. The balance sheet therefore shows materially lower reported debt and liabilities, although cash also declined from $2.050 billion to $1.579 billion in the latest period.
- Shares outstanding: Reported shares outstanding increased from 342 million to 340 million, 345 million, and 361 million across the four periods. The latest figure is 19 million shares / 5.6% above the oldest reported level, indicating dilution or a reporting-basis change.
Financial Health
- The latest period shows strong operating performance: $4.453 billion of operating income, a 34.47% operating margin, and $3.511 billion of FCF.
- Cash generation is the clearest positive trend. FCF rose in every supplied period, and the latest FCF is more than five times the oldest reported figure.
- Reported leverage improved substantially: long-term debt went from $2.457 billion to $0, while total liabilities declined by $3.245 billion from the oldest period. However, cash declined $469 million from 2026-04-03 to the latest period, and working capital fell from $2.274 billion to $1.394 billion.
- Liquidity remains positive, with a latest current ratio of 1.33, but it has weakened from 1.49 in the prior reported period. Inventory increased from $1.349 billion to $1.511 billion across the period sequence, which is worth monitoring alongside the decline in current assets.
- The latest net margin is exceptionally high at 72.95% and materially above the operating margin. Without additional disclosures, it is not possible to determine whether this reflects recurring operations or non-operating/one-time effects. A more conservative read should emphasize the still-strong 34.47% operating margin and robust FCF.
- The payload provides no additional debt schedule, interest expense, cash-flow guidance, or valuation data, limiting conclusions about sustainable earnings power and valuation.
Insider Activity
- Insider sentiment for 2026-06-23 through 2026-09-21 is Neutral (-10), but the transaction mix is clearly sell-heavy: $14.591 million of reported sales across 35 transactions and $0 of purchases across 22 transactions.
- Recent disclosed sales occurred largely around $441.57–$478.36, including multiple executives selling substantial dollar amounts. Examples include:
- Cynthia Tregillis sold $309,099 at $441.57 and $194,918 at $451.20 on 2026-09-03/04.
- Vidyadhara Gubbi sold approximately $1.604 million across transactions at $441.57 and $459.87.
- Stephanie Streeter sold approximately $2.519 million at prices between $447.06 and $455.00.
- Several executives reported sales around $468.88, including Kris Sennesael, who sold approximately $2.024 million.
- Many zero-dollar “buys” and “sells” appear alongside the cash transactions, which may reflect equity-compensation, tax-withholding, or administrative transfers rather than open-market purchases. They should not be interpreted as bullish buying.
- The insider data is a near-term caution signal because there are no reported cash purchases to offset the selling. It does not, by itself, establish that the stock is fundamentally overvalued or that a decline is imminent.
Multi-Timeframe Technical Context
- Ultra-short horizon — minutes: The payload contains only daily indicators and no intraday 1-minute, 5-minute, or order-book data. A reliable minutes-level setup cannot be established. The unusually wide reported session range of $151.42–$799.87 makes execution and headline/print validation especially important.
- Short horizon — hours to days: Price at $441.36 is slightly below the 12-day EMA of $441.38, below the 20-day SMA/Bollinger middle of $449.18, and below the 26-day EMA of $456.90. This indicates short-term price weakness.
- RSI is neutral-to-soft: RSI-14 = 44.29 and RSI-21 = 45.71. The stock is not technically oversold, so the data does not yet show a strong mean-reversion signal.
- MACD is negative at -15.51 versus a signal line of -14.61, indicating bearish momentum, though the gap is relatively modest.
- Price is above the Bollinger lower band at $410.79 and below the upper band at $487.57, leaving room for movement in either direction.
- Current volume is 13.52 million, versus a 20-day average of 6.21 million, or roughly 2.2 times average. The elevated volume raises the significance of the current price action but does not identify whether buying or selling dominated.
- Long horizon — weeks to months: The stock remains above its 200-day SMA of $385.87, a constructive longer-term condition. However, it is below the 50-day SMA of $481.71, and the 200-bar gain of 164.29% means the broader trend has been powerful but volatile. The combination of price below the 20-, 50-, and 26-day averages while remaining above the 200-day average is consistent with a medium-term correction inside a still-positive longer-term trend.
Bull / Bear Cases
- Short-term bull case:
- Price holds above the lower Bollinger band at $410.79 and reclaims the $449.18 middle band.
- A move through the $456.90 26-day EMA would improve short-term momentum, while reclaiming the $481.71 50-day SMA would challenge the current medium-term weakness.
- The strong FCF trajectory and elevated volume could attract buyers if price stabilizes and momentum indicators turn upward.
- Short-term bear case:
- Price remains below the 20-day, 26-day, and 50-day averages, with MACD still negative and RSI below 50.
- A decisive break below $410.79 would indicate loss of the current Bollinger support zone. The next major reference is the $385.87 200-day SMA.
- Insider activity is heavily sell-skewed, with $14.6 million of reported sales and no reported cash purchases during the stated period.
- Long-term bull case:
- Revenue, operating profitability, operating cash flow, and FCF all improved across the supplied periods. FCF rose from $599 million to $3.511 billion, while operating margin expanded from 28.11% to 34.47%.
- Reported long-term debt fell from $2.457 billion to $0, and total liabilities declined materially. If the operating and cash-flow improvements are sustainable, the balance-sheet profile supports a stronger long-term thesis.
- Price remains above the 200-day SMA, preserving a constructive primary-trend signal.
- Long-term bear case:
- The latest gross and operating margins both declined from the immediately preceding reported period, by 1.37 and 1.19 percentage points, respectively.
- The latest net margin of 72.95% is far above operating margin and may contain non-operating or one-time effects; the payload does not provide enough detail to assume it is recurring.
- Liquidity weakened in the latest period: current assets fell $1.277 billion from the prior period, working capital fell $880 million, and cash declined $471 million.
- Shares outstanding rose to 361 million, up 5.6% from the oldest reported period, which can dilute per-share participation in future gains.
- The stock is substantially below the reported $799.87 high, and persistent insider selling could add supply pressure if the technical correction continues.
