MRVL is a $4bn company, doesn't look a mistake to me. The money in ARM is not in making the chips but in making the products. Intel actually makes as many ARM chips as anyone as it never sold the Xscale network chips to Marvell which is why it is the biggest contributor to ARM revenue.
Thank you for your knowledgeable response. I have owned many tech stocks since I started investing in 1997. From 1997 to 2000 you couldn't lose because the tech bubble was in full bloom. Now it seems all the big tech companies are paying dividends and are "blue chip" stocks. So I try to figure out what are the best tech companies to own. I currently I own Intel and Broadcom. Hard to not buy more Intel and this price. I have bought shares of Intel at $18-$23. So I am a bit underwater right now; but hoping Intel will break free of this negativity surrounding it.
