Whether the lead banks are using up the greenshoe in stabilising the stock is unclear. Debuts have been tough in every region and banks have quickly given up on burning through greenshoes in an effort to support stock prices. On Delta Lloyd the leads used less than 30% of the greenshoe before conceding it was futile and letting the stock fall. Ultimately in that case the stock settled and moved gradually back above issue price and most of the greenshoe could then be exercised.
