On June 15, Onto Innovation rose 6.61% in regular trading, trading at $336.205/share, with turnover of $134 million. The rally was catalyzed by Morgan Stanley initiating coverage with an Overweight rating and a $371 price target, reinforcing bullish institutional sentiment.

The stock had previously plunged over 15% following the announcement of an $1.1 billion convertible preferred notes issuance, with shares bottoming at $253.24 on June 5. Oppenheimer had earlier noted the selloff was primarily driven by hedging activity related to the convertible offering rather than fundamental deterioration, identifying the pullback as an attractive entry point. Since that low, the stock has now rallied over 34%, with Morgan Stanley's initiation adding fresh institutional endorsement to the ongoing recovery thesis.

Within the Semiconductor Equipment sector, individual stocks showed mixed performance: AXT Inc up 13.91%, Lam Research up 5.17%, Applied Materials up 3.31%, ASML Holding NV up 0.66%, KLA-Tencor down 0.35%.
