A company separates a division and lists it by handing its shares to existing holders. There is no buyer and no offer price: the opportunity is not a spread, it is a mispricing at debut.
Forced index selling often leaves the spun-off unit mispriced at debut.
Live deals are shown with your account, according to your plan.
The mechanics, step by step.
Step 1
The separation is announced along with the distribution ratio.
Step 2
At debut many funds sell by mandate: the unit fits neither their index nor their size band.
The parent distributes 1 share of its subsidiary for every 4 you hold. Many of the parent's funds cannot keep a small subsidiary and sell it in the first sessions.
Forced selling, not fundamentals, sets the first price: that is where the asymmetry is.
Hypothetical figures to explain the mechanics. Not a real case and not a recommendation.
Step 3
That forced selling, unrelated to information, pushes the price down.
Step 4
You buy into the pressure and wait for the shareholder base to normalise.
