10 Green Days In A Row: Unity Software Stock Is Up 46%
A sustained run has pushed the software stock higher, but the underlying financial picture presents a more complicated story for investors to weigh.
Unity Software (U) has seen its stock price climb for 10 consecutive trading days, delivering a cumulative gain of 46% over the period. For anyone holding the stock, that streak has added about $6.4 billion to the company’s market value.
The move has been driven almost entirely by the stock itself. Over the same 10 trading days, the S&P 500 returned just +4.0%.

|---|---|---|
| 1D | 1.0% | -0.2% |
| 10D (Current Streak) | 45.9% | 4.0% |
| 1M (21D) | 53.2% | 3.3% |
| 3M (63D) | 69.5% | 3.8% |

| 2024 | -45.0% | 23.3% |
| 2023 | 43.0% | 24.2% |
Is this momentum backed by the fundamentals?
The evidence is mixed. Unity’s revenue over the last twelve months grew 14.0%, outpacing the S&P 500 median revenue growth of 8.3%. The market may be focused on this top-line performance.
However, the company’s profitability metrics tell a different story. Its operating margin over the last twelve months is -30.4%, compared to an S&P 500 median of 18.4%. Unity also has negative trailing earnings. Such streaks are exceptionally rare in the broader market; only 1 stock in the S&P 500 is currently on a winning streak of 10 days or more.
A streak is information, not an instruction.
An extended run like this is a clear signal of momentum and heightened market attention. It is not, by itself, a reason to buy or sell. The disciplined response is to use the new price as a prompt to re-evaluate the business.
The core question remains whether the company’s long-term prospects justify its current valuation. The numbers here provide a starting point for that assessment, weighing the company’s growth against its current lack of profitability.
A run like this is worth respecting, and worth testing: the momentum that lasts is usually the kind management itself is underwriting. Our Guidance Momentum screen tracks the stocks whose companies just raised their own forward numbers.

Momentum Is A Tailwind, Not A Plan
Riding a stock that rises every day feels effortless, and that is precisely the danger: the same momentum that built this run can reverse without notice, and one name’s reversal should never be able to reset your whole year.
That is what the Trefis High Quality (HQ) Portfolio is for: about 30 quality businesses screened for the fundamentals that survive momentum’s mood swings, held with rules. It has a track record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000. Watch the runs; own the resilience.
