Price cutoff: Friday, August 7, 2026 at the 4:00 p.m. ET U.S. close.
Trade horizon: roughly 1–15 U.S. trading sessions.
This is a Monday premarket screen. I am deliberately not treating thin extended-hours moves as confirmation.
Today's answer: three real gaps, no blind buy
The broad market is starting Monday in a decent mood. In a Reuters snapshot at 5:37 a.m. ET, S&P 500 futures were up about 0.14% and Nasdaq 100 futures about 0.4%, while Dow futures were basically flat. The S&P 500 also finished Friday at a record close. That backdrop is supportive, but it creates a useful test for laggards: if the market and the relevant peer group are firm, the laggard should start participating.
My screen still has three relationships worth watching:
- L3Harris (LHX) vs. the U.S. defense complex / ITA
- Fortinet (FTNT) vs. the cybersecurity group / CIBR
- Caterpillar (CAT) vs. Deere (DE) and the industrial-capex cycle
I am not adding two extra names just to manufacture a five-stock list. More importantly, I am not calling any of these a buy before the open. LHX is closest to becoming actionable. FTNT and CAT still need stronger price confirmation.
| Rank | Candidate | Friday close | Real relationship | Biggest useful gap | What changes the setup |
|---|---|---|---|---|---|
| 1 | LHX | $286.67 | Defense / missiles vs. ITA | -8.93 pp over 10 sessions | Reclaim roughly $291.40 |
| 2 | FTNT | $159.64 | Cybersecurity vs. CIBR | -7.99 pp over 5 sessions | Reclaim $164–$165; stronger above $168.30 |
| 3 | CAT | $842.19 | Heavy equipment / capex vs. Deere | -17.36 pp over 20 sessions | Reclaim $857, preferably $868 |
Relative performance: the gaps are not all the same
The table below shows the candidate minus its benchmark. Negative means the candidate lagged. These are regular-session close-to-close returns through Friday, so the numbers have not changed simply because the calendar moved from Sunday to Monday morning.
| Pair | 1 session | 3 sessions | 5 sessions | 10 sessions | 20 sessions |
|---|---|---|---|---|---|
| LHX minus ITA | -1.29 pp | +0.44 pp | -1.16 pp | -8.93 pp | -6.30 pp |
| FTNT minus CIBR | -1.80 pp | -5.05 pp | -7.99 pp | -5.92 pp | -5.15 pp |
| CAT minus DE | -2.70 pp | -4.48 pp | -1.39 pp | -4.07 pp | -17.36 pp |
The raw returns behind those gaps matter too:
- LHX: -0.99%, +0.48%, +3.47%, -4.51%, -1.41% over 1/3/5/10/20 sessions. ITA: +0.30%, +0.04%, +4.63%, +4.42%, +4.89%.
- FTNT: -0.29%, -5.14%, -1.43%, +4.77%, +1.35%. CIBR: +1.51%, -0.09%, +6.56%, +10.69%, +6.50%.
- CAT: -1.72%, -3.92%, +3.36%, -5.24%, -11.57%. DE: +0.97%, +0.56%, +4.75%, -1.17%, +5.79%.
1. L3Harris: still the cleanest catch-up watch
LHX is the name I would watch first after the bell.
The relationship is straightforward. L3Harris sells into the same U.S. and allied defense-spending cycle that supports the ITA aerospace-and-defense ETF and peers such as Lockheed Martin and Northrop Grumman. The latest operating numbers do not look like a company whose demand has cracked: Q2 orders were $7.3 billion, book-to-bill was 1.2x, backlog reached a record $42 billion, revenue grew 8%, diluted EPS grew 28%, and management increased 2026 revenue and EPS guidance.
The stock's late-July damage had a specific reason. Investors disliked the delay around the planned Missile Solutions IPO even though the underlying missile business remained strong. That is a real risk — not something to hand-wave away — but it is different from collapsing orders or a guidance cut.
The price action since that selloff is also why LHX ranks above the other two. The stock stabilized quickly, put together several higher closes into August 6, and only slipped modestly Friday. It has already shown some evidence that the post-earnings sellers are exhausting themselves.
LHX plan
| Item | Level / condition |
|---|---|
| Observation area | Roughly $284–$290 |
| Catch-up trigger | Reclaim and hold above roughly $291.40 |
| Better confirmation | Relative strength versus ITA remains positive after the reclaim |
| Invalidation | Sustained close below roughly $276 |
| Likely catalyst | New defense/missile awards, continued estimate support, or simply the market digesting the IPO delay |
| Main risks | Missile Solutions IPO valuation/timing, fixed-price contract margins, governance/executive concerns, defense-sector reversal |
Analyst, news and community temperature
The professional read is constructive on operations but less relaxed about valuation and corporate actions. The company itself raised guidance after Q2. Barron's coverage of the post-earnings drop focused heavily on the Missile Solutions IPO delay rather than a collapse in demand.
The retail conversation is useful precisely because it is not uniformly bullish. A recent r/options discussion noticed the same defense-sector divergence, but commenters also focused on executive turnover, fixed-price-contract margin risk and governance. That is the right emotional read here: people can see the backlog, but they are not willing to ignore the reasons the discount opened.
That makes LHX a better catch-up candidate than a hype trade. I still want the price to do the final bit of work.
2. Fortinet: the sector is strong; the stock has to prove it can rejoin
FTNT has the most consistent short-window lag in today's table. It trails CIBR across 1, 3, 5, 10 and 20 sessions, with the five-session gap close to eight percentage points.
The relationship is genuine. Cybersecurity has been one of the stronger technology groups recently. IBD highlighted a breakout in the HACK cybersecurity ETF last week, and research covered by Business Insider over the weekend argued that agentic AI is expanding the attack surface and could drive more security spending. Fortinet was among the infrastructure names highlighted as positioned to benefit.
Fortinet's own quarter does not look broken either. Its July 29 Q2 release showed revenue up 26% to $2.05 billion, product revenue up 52%, billings up 33% to $2.37 billion, and non-GAAP EPS up 41% to $0.90. The company also raised its 2026 revenue-growth outlook.
So why am I not buying it at $159.64 just because CIBR has run ahead?
Because FTNT fell for three consecutive sessions into Friday and has not yet shown stabilization. A lagging stock inside a strong sector can be an opportunity, but until it stops losing relative strength it can also be the market warning you that the group has better places to put money.
FTNT plan
| Item | Level / condition |
|---|---|
| Observation area | Roughly $158–$161 |
| First trigger | Reclaim $164–$165 |
| Stronger confirmation | Push back above roughly $168.30 and hold |
| Invalidation | Sustained close below roughly $154–$155 |
| Likely catalyst | Continued cybersecurity-sector strength, estimate support, AI-security demand narrative |
| Main risks | Valuation, continued relative selling despite a strong group, competitive pressure, broad tech reversal |
Analyst opinion is still mixed. July rating/target aggregators show several target increases and positive calls alongside persistent Underperform/Reduce views. I would rather use that disagreement as a reason to demand price confirmation than cherry-pick whichever target supports the trade.
Community sentiment is similarly noisy. Stocktwits' indexed FTNT stream has been cautious around the recent pullback, while smaller Reddit analyses after earnings have tended to be bullish. I do not treat either as evidence. What matters is the split itself: the business numbers look strong, but traders are still arguing about how much growth is already priced in.
3. Caterpillar: the biggest gap, but also the easiest one to chase badly
CAT's 20-session lag versus Deere is enormous: about 17.4 percentage points. That is exactly the kind of number that can tempt a catch-up strategy into doing something stupid.
The reason it remains on the watchlist is that the latest quarter was excellent. Reuters reported Q2 revenue of $20.54 billion, up 24%, construction-segment revenue up 35%, power-and-energy revenue up 17%, adjusted EPS of $8.17 versus $6.20 expected, and backlog of $72.1 billion. Management raised its 2026 sales-growth forecast, with AI data-center construction and backup power demand contributing to the boom.
That is a strong fundamental case. It is not a clean entry signal.
CAT surged after earnings and then gave back ground. The stock is also carrying more narrative and valuation risk than the other two. Barron's reported a Baird downgrade tied partly to concerns about the sustainability of hyperscaler capex and regulatory pressure on data-center construction. Retail discussion over the last few days has the same tone: people are excited that a machinery company has become an AI-infrastructure beneficiary, but many are openly asking whether the run has gone too far.
CAT plan
| Item | Level / condition |
|---|---|
| Observation area | Roughly $836–$850 |
| First trigger | Reclaim roughly $857 |
| Stronger confirmation | Move above roughly $868 and hold |
| Invalidation | Close below roughly $830 |
| Likely catalyst | Further positive order/backlog evidence, upward estimate revisions, continued data-center and power demand |
| Main risks | Valuation, data-center permitting/regulation, cyclicality, tariffs, further post-earnings profit-taking |
CAT is the clearest example of why the report now separates “interesting gap” from “actionable trade.” The gap is huge. I still want the stock to turn first.
The seven-session audit: same data, same lesson
I reran the decision rules across the previous seven U.S. trading sessions using only information that would have been available at each historical cutoff.
There is one awkward but important detail today: no new regular U.S. session has happened since Friday's close. That means Monday premarket does not magically add a new historical outcome to the audit. The data set is the same one available in the weekend screen.
The conclusion remains useful: the looser version of this strategy was too eager to buy the first large divergence after an event-driven selloff. The revised version works more sensibly when it requires:
- A real economic or historical relationship.
- Meaningful divergence across multiple windows, not one dramatic day.
- No guidance cut, balance-sheet shock, dilution, legal/product event or clear structural weakness explaining the lag.
- A credible catalyst or supportive estimate backdrop.
- Stabilization or a relative-strength reclaim after the divergence appears.
That fifth rule is doing most of the work today. LHX is closest to passing it. FTNT and CAT have not done enough yet.
I am intentionally not publishing a raw hit rate from a seven-session sample. That would make the method look more precise than it is.
Near misses I still reject
Because there is no new regular-session close yet, the main rejects from the weekend screen remain rejects rather than being promoted just to create fresh content.
| Rejected setup | Benchmark | Why it still fails |
|---|---|---|
| GE Aerospace (GE) | RTX | Large 20-day gap, but the 5- and 10-day relationship has already converged too much. |
| Johnson & Johnson (JNJ) | XLV | The measured gap is too small to justify a short-horizon catch-up thesis. |
| ASML (ASML) | SMH | It is already outperforming on the shortest windows; part of the catch-up has happened. |
| Northrop Grumman (NOC) | ITA | It is not a laggard across the measured windows anymore. |
| Micron (MU) | Semiconductor basket | Company/industry-specific capacity concerns make the weakness too explainable for a clean relative-value setup. |
A laggard is not automatically mispriced. Sometimes it is simply losing for a reason.
What I am watching after the open
The order is simple.
LHX first. If it gets above roughly $291.40 and starts beating ITA intraday, the catch-up thesis becomes much more interesting.
FTNT second. I want $164–$165 back before treating the cyber gap as a trade rather than a warning. A move through $168.30 would be much better.
CAT third. The 20-day gap is spectacular, but I would rather buy evidence of a turn above $857–$868 than buy a falling stock at $842 just because Deere did better.
The macro calendar matters too. The Bureau of Labor Statistics is scheduled to release July CPI on Wednesday, August 12 at 8:30 a.m. ET. With rates and inflation expectations still driving equity multiples, any 1–15 session trade opened early this week carries that event risk.
