Research · Stream 2 of 2
IPO Toxic Detector — why short, and when.
The second stream of our research desk. Built from a multi-year study of US IPOs, this stream does not chase hot IPO launches — it isolates IPOs that are likely to fail, and frames them as short-side research setups with explicit borrow and liquidity context.
Who we are
Same research desk as Insider Edge. One platform, one VIP membership, two independent research streams with separate Telegram channels so signal types never get mixed up. This page documents the IPO stream.
What we studied
Sample
2,792
US IPOs in the research set
Window
20+ years
multiple cycles, not a single regime
Iterations
26 phases
train / test split — rules are not fit to one window
Development and selection windows were consulted repeatedly across research phases. A genuinely untouched future holdout for final customer performance claims is not claimed here. Treat IPO results as research framing with explicit borrow/liquidity limits — not as a clean out-of-sample validation certificate.
The main finding
Long IPO
No durable buy-side historical finding at IPO
Taken as a population, IPOs do not hold up as long ideas. Aggregate post-IPO drift is negative, and the narrow set that does run up is already priced in by the time retail can participate on equal terms.
Short toxic IPO
The historical research finding shows up on the short side
When a toxic setup is detectable at the structural level (failed breakout, early exhaustion, distribution), short-side historical research findings recur across the long study window. Forward validation is still required before any customer performance claim. This stream is research context — not an executable strategy guarantee.
Put differently: the IPO market behaves much closer to a distribution market than an accumulation market. The stream is designed around that fact — it surfaces only setups where the short-side thesis is both structurally present and executable.
What we look for
Failed breakout
Post-IPO push that fails at a structural level, with the subsequent tape showing rejection rather than consolidation.
Early exhaustion
Narrow early run into weakening participation, often visible in breadth and tape characteristics before price breaks.
Weak continuation
Up-moves that lack follow-through. The pipeline favors setups where the stock cannot reclaim prior highs on comparable flow.
Distribution / volume problems
Volume patterns inconsistent with accumulation — wide spreads into rallies, tighter spreads on weakness, and unlock-adjacent liquidity shifts.
What you get as a user
VIP
Dedicated IPO Toxic Detector VIP Telegram channel. Full /ipo list and detail pages. Verdict, score, reasons, timing, borrow / HTB context and the SEC primary-source link on every row. Daily VIP cap to keep noise low.
Public
Limited delayed teasers in the shared public Telegram channel, rate-limited weekly. Public teasers are marketing — full research lives on VIP.
Honest limits
Not every IPO is shortable
Many IPOs sit on HTB with no locate. Even when the setup is clean, execution can be impossible on your broker for hours or days.
Borrow / fees / slippage
Borrow rates on recent IPOs can be punitive. The per-row detail page reports the pipeline’s borrow APR context — your real cost will differ by broker.
Low frequency by design
The filter is deliberately tight. You’ll see a handful of VIP rows per week at most, not a firehose.
Execution depends on broker
The stream delivers research output, not a filled order. Position sizing, risk, and the final execution decision are yours.
This is research, not financial advice. We never publish a BUY idea on the IPO stream — it is short-side only by design.
