Subscription capital versus allocated shares

IPO subscriptions often require more cash than the final share allocation. Model the invested or allocated amount rather than assuming every dollar is deployed.

Listing-day scenarios

Use both upside and downside assumptions. IPO returns can be concentrated in a short period and can reverse quickly after listing.
