Cummins Dark Pool Volume Doubles as the Stock Turns Oversold: GTA Terminal Data on Cummins and PACCAR (November 9, 2026)

Cummins builds the engines in a large share of the trucks, buses and heavy machines that fleets and contractors run. PACCAR builds Kenworth and Peterbilt trucks. When big money moves in these two stocks, it reflects what investors expect from truck orders and engine demand. GTA Terminal data from Global Traders Academy for Monday, November 9, 2026 showed something unusual in Cummins: off-exchange volume more than doubled while the stock sat near oversold levels. Here is what the data showed, and why it matters if you are pricing a truck or repowering a machine.

Cummins: dark pool volume up 125% while the chart turned oversold

According to GTA Terminal data published at 6:36 PM ET on November 9, an average of 936,866 Cummins shares a day traded off the exchanges over the five sessions through November 9. That is 125% more than the five sessions before, which averaged 416,869 a day. The heaviest day was November 5, with 1,377,395 shares off-exchange. GTA lays it out in its five-session Cummins off-exchange trend.

The chart and the options money pointed the other way. In its 4:42 PM ET report, GTA showed Cummins closing at $466.47 on November 9, below its 20-day average of $509.87 and its 50-day average of $524.73. The stock was 37% below its 52-week high with an RSI of 26, which counts as oversold. In the latest scan, 22% of Cummins options premium was in calls and 78% in puts, a bearish lean.

The dark pool picture was the bullish piece. On November 6, 879,733 Cummins shares traded off the exchanges, 1.6 times the 20-session normal, on a 3.6% gain, a pattern traders often read as institutions accumulating. GTA summed it up plainly: the chart and options lean bearish, the dark pools lean bullish. The levels to watch were support at the 20-day low of $443.62 and resistance at the 20-day average of $509.87. The full set is in the Cummins chart, flow and dark pool comparison.

PACCAR: steady dark pool pace, calls ahead

PACCAR was calmer. GTA Terminal data showed an average of 1,638,774 PCAR shares a day off the exchanges over the five sessions through November 9, 9% less than the 1,809,605 a day before, which GTA described as holding near its recent pace. In the latest session, 65% of PACCAR's options premium went to calls and 35% to puts. See the PACCAR five-day dark pool reading, and keep up with new stories on the PACCAR flow and news page.

So the two names split. PACCAR drew call-leaning money with steady dark pool trading. Cummins drew put-heavy options money and a weak chart, yet the heaviest off-exchange buying of the group. That is a real conflict, and GTA reported it as one.

What this means for fleets and truckers

• Engine supply and pricing. A weak Cummins chart can reflect worries about engine and truck demand. Softer demand can mean better availability and more room to negotiate on new trucks and repowers.

• Do not assume the bottom is in. Heavy off-exchange volume near oversold levels is sometimes accumulation, but it can also be selling. If you are waiting for truck prices to drop, give the trend time to confirm.

• Lock what you can control. You cannot time the truck cycle, but you can line up financing terms before you shop, so you can move when a good unit comes up.

A signal, not a guarantee

Dark pool volume shows how much traded away from the exchanges, not who was buying or selling. Options premium can be a bet or a hedge. Treat these numbers as a signal, not a guarantee. This article is for business planning and is not investment advice.
