Seagate (STX) reached all-time highs ahead of earnings, but dropped after weaker-than-expected guidance dismayed investors. Ben Watson looks at the trading range after the latest report seeing $141 as a near-term support level for STX. On a 1-year timeframe, he highlights $165 as an upside resistance but says $141 acts as a base of an ascending triangle formation taking place. Ben also notes the RSI momentum study is showing signs of cracking.
