Marvell Technology ( MRVL -5.57% ) disclosed an expanded custom chip agreement with Google on Aug. 19, complete with a warrant tied to as much as $120 billion of future purchases -- and investors in Broadcom ( $AVGO+WL +1.21% ) treated the news as their problem. Broadcom, which designs the in-house TPU chips of Google parent Alphabet ( GOOG +1.05% ) ( $GOOGL+WL +1.22% ) , saw its shares fall about 5% that morning.
