Marvell Technology (MRVL) provided a strong outlook for Q1 revenue and earnings after two acquisitions. That may have led to its reporting a one-time decline in Q4 cash flow. Bullish sentiment has led to an unusual options trading volume in out-of-the-money puts.
MRVL is at $91.05 today, down from a recent peak, but up sharply after its after-market close earnings release on March 5. On that day, MRVL closed at $75.68, so it's still up +20% in the last week.
