Is Marvell Stock Increasing Your Market Risk?
Marvell Technology (MRVL) sells chips for AI data centers, and you may hold the stock next to funds that already follow the market. Those funds rise and fall with the S&P 500, so it matters to the rest of your money whether Marvell does the same. So how far does Marvell move when the market rises or falls?
Marvell Stock Magnifies Both Up Days And Down Days
Marvell has moved more than twice as far as the market on its down days, and further still on its up days. Over the past year, the S&P 500 lost 0.61% on its average down day. On that average down day, a $10,000 holding of Marvell lost about $147. The index gained 0.63% on its average up day, and Marvell added about $236 to the same holding on that day.
Marvell’s swings were also far wider than the index’s. Its volatility, the size of its daily swings scaled to a year, was 79.2% over the past year, against 13.0% for the S&P 500. For each 1% the index moved, Marvell moved about 3.04% on average. So Marvell does not steady money that already follows the market. It adds to the market risk you already carry.
Can Marvell Holders Expect Calmer Trading From Here?
Probably not, in our reading, since Marvell earns most of its revenue from one market. Data centers brought in 79% of revenue in fiscal Q2 2027, management said on that quarter’s call. Management is also forecasting much more from that market. It raised its fiscal 2028 revenue outlook for the whole company to about $18 billion, from $16.5 billion a quarter earlier. It has expanded its agreement with a key customer, and it expects sales of custom chips to more than double. The outlook and the custom chip target are forecasts, not results, which is why we think swings like the past year’s are likely to continue.
Marvell’s swings are also not only the market’s. On a scale where 1 means two prices always move together, Marvell and the S&P 500 scored 0.5 over the past year. So a good part of Marvell’s swing looks like its own, on top of the market’s.
Has Marvell Earned Enough For Its Risk?
Marvell holders have been paid more than the market, but not in proportion to the swings. Over the past five years, Marvell returned 35.5% a year, against 13.6% for the S&P 500. But its volatility over the same five years was 65.1% a year, against 17.0% for the index. Dividing the return by the volatility shows how much return each unit of swing has earned. That works out to 0.55 for Marvell and 0.8 for the S&P 500 over the five years.
On the past year’s record, Marvell is likely to add to your gain on the market’s next up day and to your loss on its next down day. If your other holdings also depend on spending on AI data centers, Marvell adds to that bet instead of spreading it. Marvell has yet to deliver the revenue it has forecast for fiscal 2028, and whether that extra risk pays may turn on it.
How To Act On MRVL?
Now you know MRVL better. And that’s our purpose: to make you informed before you invest your money. However, making a bet on a single stock carries its own risks.
There is a smarter choice. Since its inception, the Trefis High Quality (HQ) Portfolio has beaten the benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000. And it did so without taking the concentrated risk that comes with do-it-yourself stock picking.
