IPO & SPAC Lock-up Expiry Impact

Overview

This pillar analyzes the impact of IPO and SPAC lock-up period expirations on the stock prices of tech companies. It identifies these scheduled events to forecast potential selling pressure from insiders, providing a valuable edge for short-term price predictions.

What It Does

The analysis pinpoints upcoming lock-up expiration dates for recently public technology firms. It quantifies the potential market impact by calculating the size of the share float being unlocked and estimating the profit incentive for early investors and insiders to sell. This data is synthesized into a predictive score indicating the likelihood of a temporary price decline.

Why It Matters

Lock-up expirations are pre-scheduled events that predictably inject a large supply of shares into the market, often leading to downward price pressure. This pillar transforms a known market catalyst into an actionable trading signal, allowing users to anticipate volatility and price drops that others may overlook.

How It Works

First, the system scans SEC filings to identify lock-up expiration dates for tech IPOs and SPACs. Second, it calculates the percentage of total company shares that will become eligible for trading. Finally, it assesses the cost basis of early investors to gauge their incentive to sell, generating a pressure score to forecast the event's impact.

Methodology

The core analysis focuses on a 20-day window surrounding the expiration date (10 days before, 10 days after). A 'Pressure Score' is calculated using the formula: (% Float Unlocked / 30-Day Average Daily Volume) * (Current Price / Average Insider Cost Basis). Data is aggregated from S-1 filings, 8-K reports, and daily market data providers.

This pillar provides a quantitative edge by systematically analyzing the economic incentives behind insider selling, moving beyond simple date-watching to predict the magnitude of the impact.
