The model's market view
The source session, 2026-10-22, produced sharp earnings-driven moves in defense and software alongside a risk-off selloff in semiconductors and specialty metals. For the 2026-10-23 target session I favor follow-through in liquid earnings winners, downside continuation in the weaker semiconductor complex, and selective mean-reversion in overextended or macro-driven moves. All five selections clear the $5 price, $1B market-cap and $20M 20-day average dollar-volume floors at the source-session close.
Why each pick
LMT
Ranked first. Lockheed Martin rose 6.96% on 2026-10-22 after a substantive Q3 earnings beat and record backlog that supported a raised outlook, a company-specific catalyst capable of attracting follow-through demand. The stock clears all screens with a source-session close of $589.91, market cap of $136.15B and roughly $694M in 20-day average dollar volume. The latest quote I found is $594.805 at 10:31 ET on 2026-10-23, up 0.83% versus the prior close; this is a live intraday reference price. Direction up with continuation; the main risk is profit-taking after the gap or a broader defense-sector pullback.
BHVN
Ranked second. Biohaven jumped 25.02% on 2026-10-22 after the FDA accepted its resubmitted NDA for Vyglxia/troriluzole in spinocerebellar ataxia, a substantive regulatory catalyst. The move is already very large, and the stock is giving back gains early on 2026-10-23: the latest quote is $14.32 at 10:09 ET, down 2.52% from the $14.69 prior close. Market cap is $2.219B and 20-day average dollar volume is about $38M, so the name passes the screens. Direction down with reversal; the key risk is renewed FDA-related momentum or a short squeeze.
AEIS
Ranked third. Advanced Energy fell 12.49% on 2026-10-22 to $216.64 in a semiconductor and AI-spending selloff; the catalyst was largely sector and macro driven and therefore speculative rather than a company-specific miss. The name remains liquid, with a $9.91B market cap and about $138M in 20-day average dollar volume. The latest quote is $213.96 at 09:52 ET on 2026-10-23, still below the prior close; I use this live intraday price. Direction down with continuation; the main risk is a sharp semiconductor rebound or an oversold bounce.
CSGP
Ranked fourth. CoStar rose 7.75% on 2026-10-22 to $35.45, but the catalyst was speculative: a Keefe Bruyette price-target increase to $34 with a Market Perform rating and a broader housing rally, not a fundamental earnings surprise. The stock is already trading below that spike on 2026-10-23; the latest quote is $35.02, down about 1.2%. Market cap is $14.36B and 20-day average dollar volume is roughly $235M, so it passes the liquidity screens. Direction down with reversal; the key risk is continued upgrade-driven buying or pre-earnings positioning ahead of the Oct. 27 report.
ATI
Ranked fifth. ATI fell 10.43% on 2026-10-22 to $161.84 in a risk-off move across specialty metals, with rising yields and oil prices and sector de-rating rather than a company-specific miss; the catalyst is therefore speculative and macro driven. It still has a $22.04B market cap and about $264M in 20-day average dollar volume. The latest quote is $161.50 on 2026-10-23, slightly below the source close. Direction up with reversal on record aerospace backlog and pre-earnings stabilization; the main risk is continued sector weakness before the Oct. 29 earnings report.
