Busted IPOs: Capturing the Lockup-Expiry Bottom

A 'busted IPO' is one trading meaningfully below its IPO price -- typically 25%+ below offering. The asset class spiked during 2022-2024 as the SPAC boom unwound and growth-stock IPOs faced multiple compression. Busted IPOs are not the same as bad companies (some are fine businesses that were just mispriced at IPO); they're not the same as long-term value plays (most still have unsolved business-model issues). They're a specific subset of equities with a specific supply dynamic that retail and institutional players can sometimes exploit.

§ 02

The classic busted-IPO pattern: the stock bottoms within 30-90 days AFTER lockup expiry, not before. The pre-lockup short-selling and anticipatory selling DOES drive the price down before expiry, but the actual bottom typically forms once the largest insider blocks have cleared -- because that's when the marginal seller is no longer the desperate insider, but the late-stage hold. The 2022-2024 SPAC unwinds (Coinbase, Robinhood, DoorDash post-lockup, various 2021 growth IPOs) follow this pattern with consistent regularity.

§ 03

The single best filter for busted-IPO investing is whether the BUSINESS MODEL has structurally changed since IPO. A busted IPO of a growing SaaS company that just got valuation-compressed has different upside than a busted IPO of a meme-stock-era consumer brand whose unit economics never worked. Read the S-1 (sf-5), check the cohort tables, compare current revenue-growth rate to the IPO-era trajectory. If the business is fine and only the valuation was wrong, the busted IPO has clean upside. If the business is broken, no amount of selling exhaustion will rescue the price.

§ 04
Find a recent SPAC merger or IPO trading below its IPO/merger price by 50%+. Identify the lockup-expiry date in the S-1 or proxy materials. Plot the stock price over the months leading up to and following lockup expiry. The pattern: sharp decline pre-lockup, capitulation 30-90 days post-lockup, then either bottoming or continued decline depending on business fundamentals.
§ 05

Most busted IPOs do NOT recover to IPO price. The empirical evidence (Ritter and Welch various; the 2024 SPAC retrospective studies) shows that 5-year post-IPO returns for the bottom decile of IPOs are typically -50% to -70% from IPO price. Survivorship bias makes the headline busted-IPO winners (Spotify, Pinterest in some periods) seem more representative than they are. Most busted IPOs deserve their price; the trade is identifying the minority where the business is fine and the price is wrong.

§ 06

Busted IPOs trade meaningfully below offering price. The lockup-expiry window concentrates insider selling, typically producing the bottom 30-90 days post-expiry. The investable subset is busted IPOs where the business model still works; most busted IPOs deserve their reduced price. Pre-lockup short interest plus post-lockup analyst sentiment shift are the catalysts; survivorship bias is the main analytical trap.
