Yesterday’s tape was dominated by the ALMS crater. Today we’re flipping the lens: the day after that lupus-trial shock, what else got wrecked on Tuesday, Sept. 1 — and why cyber/software + midcaps stole the “losers” spotlight.
Quick context only: Alumis (ALMS) plunged about −56.6% on its trial miss. That story was covered hard already — we’re not rehashing it as the lead. Here’s the broader washout list beginners actually need.
Why so many names fell together
Three pressure points hit at once:
- Higher yields — 10-year near 4.79–4.80% squeezed rich valuations
- Fed hike odds — FedWatch ~68% chance of a September 25bp hike
- Risk-off tape — third straight down day for Dow / S&P / Nasdaq
When rates jump, software and growthy midcaps often feel it first. Cyber was especially soft Tuesday.
Top losers roundup (verified Tuesday movers)
Cyber / software softwash
- CrowdStrike (CRWD) — about −6.9% to roughly $215
High-multiple cybersecurity got graded harshly as yields spiked. Same-day sector chill also left Palo Alto Networks soft into/around its earnings window.
- Rapid7 (RPD) — about −10.8% (some prints near −9.7%)
Security software + rising Treasury yields = double whammy for names priced for growth.
Midcap & specialty names in the red
- Enovis (ENOV) — about −16.5%
One of the sharper medical-tech / midcap slides on the session.
- FBYD — about −16.2%
Another double-digit midcap hit — liquidity can amplify moves on tough tape days.
- OneSpaWorld (OSW) — about −10.4%
Consumer/discretionary-adjacent pressure as that sector led the downside.
- Pershing Square — about −10.3%
Closed-end / related vehicles often swing harder when risk appetite fades.
- IE — about −9.3%
- BW — about −9.3%
- SharkNinja — about −9.1%
Consumer brands don’t love “rates up + discretionary weak” days.
- EVCM — about −9.0%
Honorable mention: Dell was soft in the regular session before its after-hours AI backlog blowout reversed the narrative. Frame carefully — regular-hours DELL wasn’t the hero yet; AH was.
Sector scoreboard (simple version)
- Group: Energy — Tuesday vibe: Only major sector clearly up (oil surge)
- Group: Consumer discretionary — Tuesday vibe: Worst big-sector performance
- Group: Cyber / software — Tuesday vibe: Valuation + yield pressure
- Group: AI hardware (post-close) — Tuesday vibe: Dell rescued the overnight mood
What “stocks down” means for beginners
A red screen isn’t automatically a “sell everything” signal. Sometimes it’s:
- Company-specific (ALMS-style trial miss — rare but brutal)
- Factor-driven (rates up → growth multiples down)
- Liquidity-driven (smaller names gap harder)
Cyber’s Tuesday washout looks more like factor + multiple compression than a sudden “security is dead” thesis. Still — if you own CRWD, RPD, or similar names, know your thesis before the next 7% day.
Watch list into Wednesday
- Does cyber bounce after the flush, or do yields keep the lid on?
- Do midcap losers stabilize, or is this a multi-day de-risking?
- Does Dell’s AH strength lift related hardware while software stays sticky-weak?
Bottom line
ALMS was yesterday’s earthquake. Tuesday’s aftershock list is a cyber softwash + midcap cleanup under rising yields and 68% hike odds. Energy won. Discretionary and high-multiple software paid the bill.
Stay humble on size. Losers lists are for awareness — not FOMO shorting.
