Defend This Call.

Five flagship reports, each reduced to what has to hold up when someone pushes back: the thesis in a sentence, the numbers to know, the hardest questions with answers taken from the report, and what would change the call.

01 · LHX · Buy

L3Harris

A defense supplier with a record backlog and intact cash guidance, priced as if its 2028 targets will be badly missed.

$436Base-case value a share; expected value $425
$248.77Price at writing
$42BRecord backlog, 1.2× book-to-bill
~$3.0B2026 free cash flow guidance, about $3.5B by 2028
7.9%Discount rate: beta 0.80, about 19% debt
$231Bear case, close to the price
The pushbackThe answer, from the report
“The CEO was just removed. Why trust the guidance?”The change followed a conduct violation, not a business miss, and came after results that raised guidance. The model works from cash flow and the company’s own targets; the risk table lists the open investigations, and a cut to cash guidance is named as what would change the value.
“Your beta of 0.80 is higher than the measured 0.61. Are you inflating the discount rate?”It raises the discount rate, which lowers the value: the conservative choice. 0.80 matches defense peers; the measured figure understates risk after this year. Even at 9.0% the value is $346, still well above the price.
“GAAP margins are only about 10%. Isn’t the stock fully priced?”GAAP profit is held down by amortization from the Aerojet purchase. Free cash flow, which adds that back, has grown every year since 2023. The price needs long-run cash flow of about 9% of revenue, against 14.6% in guidance.
“The debt is high.”About $11.0 billion against $1.5 billion of cash, with $560 million of interest a year. The model deducts it, along with the Pentagon’s preferred stock, treated as debt.

What would change the call: A cut to the $3.0 billion cash-flow guidance, new findings from the conduct investigation, or the bear case (growth of 3–4% and cash flow of 12.5% of revenue) becoming the base case.

02 · JPM · Buy

JPMorgan Chase

The highest-returning large bank. On its own it looks fully priced; against an expensive market it is still cheaper than average.

$284Base-case value a share; expected value $289
$335.26Price at writing, 2.53× book
16%Sustainable return on equity assumed
9.9%Cost of equity: beta 1.05
18%Return on equity the price implies
13.9%CET1 capital ratio; about $30B of excess capital
The pushbackThe answer, from the report
“Your value is below the price. How is this a Buy?”The rating is relative. On the same assumptions the S&P 500 is worth about 68% of its price; JPMorgan is worth about 86% of its price. That is 27% better than the market, so it clears the Buy line. On its own it is labelled overvalued, and the report says so.
“Why an excess-return model and not a DCF?”Debt is a bank’s raw material, so free cash flow has no clear meaning. A bank is worth what it earns on its equity: price to book = (ROE − g) ÷ (cost of equity − g). A bank earning exactly its cost of equity is worth book value.
“Returns are 20% now. Why only 16%?”Today’s returns come with high rates and strong markets revenue. The bank’s own through-cycle target is 17% on tangible equity, about 14.5% on all equity. 16% sits between that and today.
“Does the rating survive a different market view?”Not fully: it would be Buy if the index grows 6% a year and Hold at 10%. That sensitivity is printed in the report.

What would change the call: Credit losses rising faster than expected, rate cuts squeezing net interest income, or a change to the 17% through-cycle target.

03 · AMZN · Hold

Amazon

A great business in an expensive building phase: AWS is accelerating, but capital spending has turned free cash flow negative and the price assumes margins Amazon has never earned.

$153Base-case value a share; expected value $156
$262.63Price at writing
+37%AWS growth, 39% margin
−$7.6BFree cash flow, last 12 months, as Amazon defines it
~$220B2026 capital spending guidance
29%Long-run margin the price implies, against a best year of about 12%
The pushbackThe answer, from the report
“Net income was $62.6 billion last quarter. How is cash flow negative?”Most of it was a $53.4 billion gain from revaluing the Anthropic stake. Capital spending rose $66 billion in a year to $169 billion net of proceeds, more than operating cash flow.
“You leave out the Anthropic stake.”Yes, deliberately, and the report says so: it is upside to the value. It covers part of the gap to the price, not all of it.
“The market expects AI to pay off. Why don’t you?”The base case lets margins rise from 13% to 18% by 2031, well above anything Amazon has earned. The price needs about 29%, or growth of about 23% a year for two years.
“Hold, with the value 40% below the price?”Against the market it is only 12% dearer, inside the Hold band. It would be Sell if the index grew 10% a year.

What would change the call: AWS growth staying above 30% with margins holding, operating income against guidance, or any change to the $220 billion capex plan.

04 · UNH · Buy

UnitedHealth

Margins are recovering after the 2025 collapse; the price assumes they stop at about 6%, against more than 8% before 2025.

$516Base-case value a share; expected value $519
$425.06Price at writing
88.4%Medical care ratio, from 89.9%
≥$20.502026 adjusted EPS guidance, raised a third time
5.9%Long-run margin the price implies; base case 7%
41.7%Debt to capital, above the 40% target
The pushbackThe answer, from the report
“$610 million of the improvement was reserve releases.”Agreed, and it is listed as a risk. The base case does not need it: the margin starts at 5.5% and rises to 7%, still below the 8–9% before 2025.
“There are federal investigations.”Into Medicare billing and Optum’s ties to the insurer. They are in the risk table, and their outcome is one of the next inputs the report names. The bear case, $282, is margins stuck near today’s level.
“Revenue was flat.”Deliberately: the company is shedding unprofitable members. Earnings from operations rose 52%. The model assumes 4% then 7% growth.
“The Street is at $481. Why higher?”Analysts are close to this model’s base case, and both assume margins keep recovering. The range is lopsided: the bull case is $323 above the base and the bear case $234 below, which lifts the expected value. At a 9.0% discount rate the value is $417.

What would change the call: The 2027 outlook around the turn of the year, Medicare Advantage rates for 2028, and the outcome of the investigations.

05 · COST · Hold / Wait

Costco

An excellent business with no margin of safety: the cash flows support $831.50 a share against a price of $970.31.

$395–500What peer multiples imply
$1,072Analysts’ average target
The pushbackThe answer, from the report
“Costco always looks expensive. You’d never have bought it.”The fundamentals are excellent and the report says so. A Hold is not a Sell: it is a call that the price leaves no room for error.
“Why give peer multiples no weight?”They cannot capture the membership fees and the stability of growth, and they imply only $300–500. A 70/30 blend gives about $716, which makes the call stronger, not weaker.
“The liquidity ratios look weak.”Negative working capital is the model working: members pay before suppliers are due. The cash conversion cycle is near zero, interest is covered more than 80 times and the Altman Z-score stayed above 3 every year.
“Analysts average $1,072.”Their targets build in premium multiples continuing. This analysis puts price discipline first; even the best companies can be poor investments at the wrong price.

What would change the call: A price below the cash-flow value, or growth that holds above the 8.45%-to-5.07% path the model assumes.
