Why Is a Stock Going Up When Its Fundamentals Look Bad?

A stock can rise for weeks while its fundamentals point the other way because price and reported figures run on different clocks. Price moves on expectations, today. Fundamentals are reported once a quarter and describe the past. When the market is pricing a change the filings have not shown yet, or is simply looking past what they show, the two disagree, and that disagreement is what a divergence score records.

It is the most common shape behind high divergence in our data. Across every reading of 50 or more we recorded from 1 to 18 September 2026, the widest gap sat between price structure and fundamentals in just under half. It is also the shape most often read as a verdict, in one direction or the other.

What it looked like in September 2026

Deere (DE) is the clearest case. On 1 September it read +75 with divergence 77. On 18 September it read +83 with divergence 73. In between, bias never dropped below 75 and divergence never below 72. Price structure sat near the top of its range throughout, and the fundamentals layer leaned the other way throughout. Neither moved much, so the reading held: Broadly Bullish on balance, and contested every single day.

General Motors (GM) had the same shape at a lower pitch, with bias between +55 and +73 and divergence between 63 and 70 over the same eighteen days.

Merck (MRK) is a variant where the split slowly eased. Bias went from +86 on 1 September to +63 on 14 September, and divergence from 73 to 60. Price structure and news tone both cooled while the fundamentals layer did not move, so the gap narrowed and the score came down with it.

Skyworks Solutions (SWKS) shows how the split forms. On 1 September it read -17 with divergence 6: not much happening, nothing disagreeing. Over the next two weeks price structure turned sharply up while fundamentals stayed soft, and by 18 September it read +91 with divergence 84. The score and the disagreement rose together.

When a whole sector does it

On 17 September this shape was all over healthcare. Ionis (IONS) at +53 with divergence 83. Illumina (ILMN) at +88 with 70. IQVIA (IQV) at +86 with 69. AbbVie (ABBV) at +77 with 59. Merck at +68 with 60. In each, price structure leaned positive and fundamentals leaned the other way. Healthcare's average divergence that day was 36.1, the highest of any sector we cover, against 28.5 for the market as a whole.

When the same split runs across a sector, it is often a sector story rather than a company one: money moving into a group of stocks faster than their reported figures change. The healthcare divergence board shows whether that still holds on the current public reading, and the industrials board is where Deere sits.

Reading it without reading too much into it

The tempting conclusion is that price has run ahead of the business and has to come back. The equally tempting opposite is that the market knows something the filings do not. Both are stories, and the data supports neither over the other. Price has led fundamentals many times, and it has also run on expectations that never arrived. The split says the two readings disagree. It does not say how that ends.

What it does say, for a stock you hold, is that the bias score is mostly a price structure reading right now, and that the reported figures are not confirming it. That is worth knowing whichever way you lean. Which figures are soft is a question for the numbers themselves: the gap between reported profit and cash is covered in cash flow vs profit, and the wider method in what is fundamental analysis.

The general guide to this measure is what stock divergence means, and why a high score and a high divergence can sit side by side is in what a high divergence score means.
