IPO Trading Strategy: First Day, Lockup Expiry, and Breakdowns

Newly public stocks behave differently: thin trading history, concentrated insider ownership, and a scheduled share unlock. Three tradeable windows emerge, each with its own mechanics and failure modes.

1. First-day trading (high risk, avoid chasing)

• IPOs price the night before and gap at the open. Hot deals average a 10–20% first-day pop, but dispersion is huge — many open below offer.
• Do not chase the opening spike. The first 5–10 minutes are dominated by flipper algorithms and oversubscribed retail; fills are poor and reversals common.
• The only disciplined first-day entry: wait for the first 30 minutes to set a range. Enter long only on a break of the first-30-minute high with volume, stop below the first-30-minute low. This filters the open chaos.
• Pricing context: a deal priced above its revised range that opens up 30%+ is heavily flipped — fade risk is high. A deal priced in range that opens flat offers cleaner setups.

2. Lockup expiry (the overhang trade)

• Lockup period: typically 180 days during which insiders and pre-IPO holders cannot sell. At expiry, a flood of supply can hit.
• The drift: IPOs often underperform in the 30 days leading into lockup expiry as the market prices in coming supply, then sell off on expiry day.
• Setup (short into expiry): if the IPO trades well above its offer price into the lockup, enter a short 5–10 days before expiry. Cover on expiry day or the day after, once supply clears.
• Stop: above the recent swing high. Lockup-expiry selling is statistical, not guaranteed — a strong fundamental story can absorb supply.
• The reverse setup: if an IPO holds or rallies through lockup expiry, the overhang is absorbed — bullish. Enter long on a break of the expiry-week high.

3. Post-IPO breakdown (the base-break setup)

• Most IPOs need 3–6 months to establish a trading range and shareholder base.
• Setup: after 60+ days of trading, an IPO breaking below its post-IPO base low on volume ≥ 1.5x the 20-day average is a short or avoid — it signals distribution by flippers and weak support.
• Entry: short on the break, stop above the base high, target the offer price (a full round-trip).
• Inverse: an IPO breaking above its post-IPO base high on volume after 60+ days is establishing sponsorship — long with stop below the base low.

Rules that keep IPO trading alive

• Size small. IPO volatility is 2–4x the broad market. Risk 0.25–0.5%.
• Never hold through lockup expiry unknowingly. Check the S-1 for the lockup date and unlocking share count — a 200% float unlock differs sharply from a 20% unlock.
• Skip weak-fundamentals deals. IPO trading is a technical and supply game; weak fundamentals (no revenue, no path to profit) stack odds against you.

Most retail IPO losses come from chasing first-day spikes and ignoring lockup dates. Trade structure, not hype.
