Actionable insights — How to Invest in IPOs

1. Separate the offering price from the opening price before judging the "pop"

1. Find both numbers: the offering price (what allocated insiders paid) and the opening/first-day-close price (what the public pays).
2. Treat the first-day pop as value transferred to whoever got an allocation — not the business, and not most public investors.
3. Measure every later return from the first-day close (what you could actually buy), not the offering price — the honest baseline.

• A wide gap between offering and opening price; commentary quoting gains off the offering price to flatter the result.

2. Price in the three structural disadvantages every IPO carries

1. Limited operating history — the S-1 only shows the past; you can't see how it behaves under public-market pressure.
2. Insider selling — lock-ups expire ~6 months in, releasing a wave of supply (IPOs lag most from 6–24 months after listing).
3. Information edge — the best investors saw the company years earlier at far lower valuations; you're buying at the most-informed sellers' chosen moment.

• The lock-up expiry date on the calendar; the gap between the last private round's valuation and the IPO ask.

3. Anchor to the base rates from the Ritter dataset

1. Start from the historical odds, not the story: from the first-day close over five years, 50% of IPOs were negative, 30% lost half their value or more, only 24% became multi-baggers.
2. Adjust the odds with three factors: size (under $100M sales trailed ~34% vs ~4% over $500M), profitability (profitable ~−13% vs unprofitable ~−31%), and VC backing (~−14% vs ~−25%).
3. Flag any IPO that is large and unprofitable — the combination the data treats most harshly.

• Revenue scale, profitability and VC backing in the S-1 — the three dials that move an IPO's base-rate odds.

4. Run the five-rule entry playbook instead of buying day one

1. Avoid the IPO hype — let the initial open-market volatility pass.
2. Wait for the second earnings call — the S-1 is a snapshot; two quarters draw a trendline.
3. Nibble in year one — a starter so small a 50% drawdown wouldn't damage your portfolio or your sleep.
4. Anchor to valuation — missing a 20% move is not a disaster; buying perfection-priced is.
5. Give it time — many great stocks go nowhere their first few years; multi-baggers rarely require buying on day one.

• The second earnings report as the earliest sensible entry; a valuation that prices perfection as the disqualifier.

5. Read an IPO wave as a market thermometer, not a buy signal

1. When mega-IPOs cluster, treat the surge as information about market temperature (sellers choose the timing) rather than an invitation to participate.
2. Remember IPOs come to market when the seller's odds are best — peak euphoria — which is structurally the buyer's worst entry.
3. Keep the watch list, not the order ticket: let the froth, the lock-ups and the first real numbers do the work before committing.

• A cluster of richly-priced listings as a sentiment gauge; the temptation to chase day-three pops as the contrarian warning.
