Western Digital daily stock price chart, Source: TradingView
From the daily chart of Western Digital's stock price, the stock has recently tested the 144-day moving average three consecutive times, with the closing price remaining above it each time, indicating strong support at this moving average. A short-term bottom for the stock may have formed, and last Friday's 5.86% surge above the 144-day moving average further strengthened the market's bullish momentum.
Currently, the primary resistance level above is the gap between $500 and $519. If the stock fills this gap and continues to rise, the next target will be to challenge the August 17 rebound high of $548.60. If the stock can break through and hold above this level, it will open up upside potential toward the $600 mark.
On the downside, the primary support level below is in the $400–$420 range. If the stock drops below $400, it may enter a deeper pullback phase in the short term, potentially falling toward the 0.786 Fibonacci retracement level near $357. Further down, support in the $300–$320 range should be watched.
