Four ASX shares that are falling more than most today are listed below. Here's why they are dropping:

Boss Energy Ltd (ASX: BOE)
The Boss Energy share price is down 6% to $1.91. This appears to have been driven by broad weakness in the uranium industry today. In addition, short sellers have been loading up on Boss Energy and other uranium shares. So much so, a total of 21.6% of its shares are in the hands of short sellers at present. And with its shares down 47% over the past six months, they have done well from this one.
G8 Education Ltd (ASX: GEM)
The G8 Education share price is down 13% to 70 cents. This morning, this childcare operator revealed that its occupancy levels remain subdued. This is due to "the macroeconomic environment remaining challenging and affordability and cost of living pressures continuing to impact families." According to the release, as at 2 November 2025, the company's spot occupancy was 68.3%, which is 6.6% points lower than the prior corresponding period. In light of this, it has downgraded its full year earnings guidance to be in the range of $91 million to $98 million.
Novonix Ltd (ASX: NVX)
The Novonix share price is down 11% to 50.25 cents. This has been driven by news that auto giant Stellantis has cancelled its offtake agreement with the battery materials company. In response, the company said: "While NOVONIX is disappointed with this decision, it remains focused on its deliveries for Panasonic and PowerCo and continuing to provide samples to 15 current and potential customers for battery and industrial applications." Management advised that the deal fell through after the two parties failed to agree upon the unique battery cell product specifications and milestones for mass production qualification.
Weebit Nano Ltd (ASX: WBT)
The Weebit Nano share price is down 11% to $4.58. This is despite there being no news out of the semiconductor company. However, with its shares still up 155% since this time six months ago, it is possible that some investors have been taking profit off the table on Tuesday. In addition, with a market capitalisation of almost $1.1 billion, and quarterly cash receipts of $7.3 million, investors may think this speculative stock is severely overvalued.
