MBG.DE Mercedes Benz Group AG - Trade Plan — 2026-05-07

TL;DR

SHORT MBG.DE on a scaled-in bounce into the EUR 49.50–50.50 resistance shelf (mid EUR 49.75), hard stop EUR 51.95 (above the EUR 51.73 HVN / descending-channel upper line), primary target EUR 40.75 (channel measured move), stretch EUR 35.00 on second guidance cut. Size 3.5% NAV (EUR-denominated) with 0.50% NAV at risk — held below the single-position cap and well below the conviction-4 ceiling because this is the system's first short-side directional call and first tracked decision on MBG.DE; the first-call calibration discipline binds. Horizon 75 trading days through the 2026-07-24 H1 print, with the 2026-06 CPCA China data release as the primary mid-flight checkpoint. Reward:risk on TP1 ≈ 4.1:1.

Source verdict

"SHORT — directional short on Mercedes-Benz Group AG (MBG.DE) at EUR 48.19. Primary downside target EUR 40.75 (channel measured move + bear-case sell-side PT cluster), stretch target EUR 35-40 on a second guidance cut at the 2026-07-24 H1 print. Invalidation: weekly close above EUR 51.73 (HVN cluster / channel upper line) or a May 2026 CPCA print showing the China JV running at or above the Q1 148k quarterly pace."

Decision and conviction are accepted as inputs and not relitigated here.

Direction & instrument

SHORT — single-leg short stock (cash equity short on Frankfurt Xetra). Rationale:

• Verdict is unambiguously SHORT with conviction 4 across an aligned analyst pack (fundamentals BEARISH 4, technicals downtrend ADX 63.6, estimates ERM_90 -10.6%, macro HEADWIND 4, news 3x high-materiality negative).
• No options structure is used. The LIMITED_OPTIONS_DATA flag from the options-flow analyst means we cannot price IV, skew, or term structure for Eurex MBG options; structuring a put-spread or collar inferentially would add execution risk without adding conviction-grade information.
• A pair-short was considered (long BMW.DE / short MBG.DE) to isolate the Mercedes-specific China-mix erosion vs sector beta. Rejected: the macro-factor analyst flagged the entire German auto sector as a HEADWIND regime (US 25% tariff effective 2026-04-03 hits BMW too), so a long BMW leg would dilute the trade rather than isolate alpha. Outright short captures both the sector beta and the Mercedes-specific underperformance.
• Borrow/locate: MBG.DE is a DAX-40 constituent with daily volume on Xetra ~5–8m shares; institutional borrow is assumed available at reasonable cost. Borrow rate is not directly observable in our data stack, but for DAX-40 ordinary shares the rate is typically <1% annualised and unlikely to materially erode the trade economics over a 75-day horizon. Operational pre-trade check (risk committee should confirm with the prime broker): locate confirmed and borrow cost ≤ 50 bps annualised. If unborrowable or borrow rate

  100 bps annualised, downgrade to HEDGED via long puts (subject to options data availability) or NO-TRADE.

Entry

• Method: scaled (1/2 + 1/2)
• Entry zone: EUR 49.50 – EUR 50.50
• Mid / blended fill assumption: EUR 49.75
• Validity: GTC, working for 10 trading days; if price breaks to a new 52-week low (close < EUR 47.40) before the bounce, see "Trigger 2" below.

Entry logic. Two valid triggers:

1. Bounce-into-resistance (preferred). Price rallies into the EUR 49.50–50.50 supply zone (April 28 swing high cluster). Place limit sells:

   • Tranche 1 (1/2 of full size, ~30 shares): limit EUR 49.50
   • Tranche 2 (1/2 of full size, ~30 shares): limit EUR 50.40 This produces an average fill near EUR 49.75–49.95 if both fill, or EUR 49.50 if only the first fills. The entry zone is below the EUR 51.43–51.73 HVN ceiling, leaving room for the stop while capturing the higher-probability mean reversion to resistance that the technical analyst flagged for short sellers.

2. Breakdown trigger (fallback). If price closes below EUR 47.40 on volume ≥ 1.3× the 50-day average before the bounce triggers, treat as confirmed channel breakdown and short the open of the next session at market for full size, stop tightened to EUR 49.95 (above the EUR 49.79 prior swing low which then becomes resistance). This trigger captures the scenario where the trend continues through the 52-week low without producing the bounce we'd ideally fade.

Why not market here at EUR 48.19. Entering at the current price gives away the bounce-fade premium that the technical analyst explicitly flagged as the favourable short entry zone (49.50–50.00 per technical.md timing-view table). RSI(14) at 31.5 with stochastics %K turning slightly above %D is the geometry that produces a short-term mean-reversion bounce inside a downtrend; selling into that bounce is the cleaner risk-adjusted entry. Entering market here also worsens R:R: at EUR 48.19 with stop EUR 51.95, risk is EUR 3.76 per share vs reward EUR 7.44 to TP1 (R:R = 1.98:1). At EUR 49.75 entry, R:R = 4.09:1.

Stop

• Price: EUR 51.95 (hard stop; daily-close basis)
• Type: hard stop on daily close. Intraday spikes above EUR 51.95 that close back below are not stopped out; a daily Xetra close above EUR 51.95 triggers immediate cover the following session open.
• Distance from blended entry (EUR 49.75): EUR 2.20 = 4.4% = 1.55 × ATR(14) of EUR 1.42

Justification (stop placement reasoning).

• The verdict's named invalidation level is EUR 51.73 (weekly close above the HVN cluster / channel upper line). EUR 51.95 sits 22 cents (≈ 0.4%) above EUR 51.73 to absorb the kind of tag-and-fail whipsaw that occurs at heavily traded HVNs.
• Snapped to structure: EUR 51.43 (lower HVN) and EUR 51.73 (highest HVN) form a resistance shelf. A close above the upper edge of that shelf is the regime invalidation per the technical analyst's "What Would Invalidate This View" section. EUR 51.95 is the smallest buffer that puts us decisively outside both HVNs.
• ATR sanity check: 1.55 × ATR is wider than the 1.5σ-of-daily-noise minimum the trader-skill methodology requires. We will not be stopped by routine daily wiggle.
• Worst-plausible-drawdown sanity: BOSS.DE memory flagged -10.38% single-session gap precedent for German consumer/discretionary exporters, with kurtosis 13.8. A 4.4% adverse move from entry is inside the routine 1–2 ATR band; a 10%+ overnight gap-up (e.g. on a surprise EU-US tariff exemption or activist M&A announcement) would blow through this stop. That gap risk is sized for, not stopped for — see "Thesis-invalidating events" below for the event-driven exit rules.

Why not tighter. A stop at EUR 51.00 (just above EUR 50.52 swing high) would tighten R:R to ~6.7:1 on TP1 but increases stop-out probability inside routine bounce noise: at ATR EUR 1.42, an intraday bounce of 1 ATR from a EUR 49.75 entry tags EUR 51.17 — too close to a EUR 51.00 stop. The stop must respect both the structural level (HVN at 51.73) and the volatility regime; tightening below EUR 51.73 violates the structural test.

Targets

Why TP1 is a partial, not full, cover. EUR 47.40 is the natural level where the first wave of short-covering pressure shows up (prior swing low + 52-week low). Covering 1/3 there locks in positive trade P&L and de-risks the remaining 2/3 to ride toward the measured-move target. The technical analyst lists 47.40 as Target 1 and 40.75 as Target 2 — we mirror that staging.

Why we don't set TP at the highest-conviction outcome. TP2 (EUR 40.75) is the channel-measured projection — a level the pattern projects to, not a level we hope for. TP3 (EUR 35.00) is explicitly conditional on a discrete catalyst (second guidance cut) and is not booked as a "target we expect to hit"; it's a trail extension if a specific event fires.

Trade management

Partial profit-taking ladder.

Stop-adjustment rules.

1. Stop is held at EUR 51.95 from initiation through TP1.
2. On TP1 trigger (close ≤ EUR 47.40 with partial cover), stop on remainder moves to entry (EUR 49.75). The trade is now risk-free on the runner.
3. On TP2-waypoint trigger (close ≤ EUR 44.00), trailing stop moves to EUR 47.40.
4. No upward stop-tightening before TP1. The position is held through the noise of routine bounces inside the channel. The stop moves only on confirmation of progress through structural levels.
5. Time-based exit: if at trade day +30 (≈ end of June 2026) price has not made a daily close below EUR 47.40 and the May CPCA monthly retail data (mid-June release) does not show Mercedes JV monthly units ≤ 50k, cover 1/2 of the position regardless of price. Rationale: the bear thesis depends on the one-of-three trigger geometry firing; if neither the technical nor the China data has fired by mid-June, the H1 print becomes the only remaining trigger and the trade is overweight one binary. See horizon discussion below.

Horizon

75 trading days (anchored by research-verdict). Spans the period from initiation through the 2026-07-24 H1 results print, which is the verdict's primary catalyst.

Catalyst calendar overlay:

Earnings-gap risk acceptance. The H1 print sits inside the horizon. We are intentionally holding through the print rather than shortening to pre-earnings. Reasoning:

• The print is the bear thesis' primary catalyst (Q2 is the first full quarter of US 25% tariff in the P&L, EUR 1.5–2bn unmitigated annualised EBIT headwind).
• 60% of the bear edge per the verdict's catalyst-asymmetry framing comes from one of the three triggers firing at or before the print; closing pre-print throws away the asymmetric tail where Cars RoS guidance is cut and the stock gaps down 10–15%.
• The 3.5% position size (well below the 10% cap) is sized in part to absorb a +10% adverse gap-up at the print (worst-case loss on this position ≈ 10% × 3.5% NAV = 0.35% NAV, inside the 0.50% NAV risk budget).

  rationale: >
    Method 1 (fixed-fractional, 0.50% NAV at risk on EUR 2.20 stop
    distance) sized at 209 shares = 10.8% NAV — bound by the 10%
    single-position cap. Method 2 (vol-targeted at 0.20% daily NAV
    against HV20 27.6%) sized at 11.5% NAV — also cap-bound. Method
    3 (quarter-Kelly with conviction-4 p_win=0.62, R:R=4.09) sized
    at 13.2% NAV — also cap-bound. All three methods exceeded the
    single-position cap; the cap was the limiting factor on standard
    sizing. Then applied AMZ.US first-call precedent (2026-05-06,
    3.5% NAV neutral sizing on a first directional call where no
    prior calibration data existed). MBG.DE is the system's first
    tracked decision on this name AND the system's first short-side
    directional call ever — two layers of first-call uncertainty.
    Sized at 3.5% NAV ceiling consistent with AMZ.US precedent. The
    conscious under-utilisation of the 0.50% NAV risk budget (actual
    risk 0.14% NAV) is the cost of this calibration discipline; the
    risk committee can debate whether to release the constraint.

  currency_note: >
    Position is EUR-denominated on Frankfurt Xetra. NAV reference is
    USD 100,000 (research-mode default), translated to EUR 92,000 at
    EUR/USD 1.087 spot for sizing math. Trader assumes the portfolio
    has EUR-funding capability for the short proceeds; if the
    portfolio is USD-only and EUR financing must be raised, factor
    a small additional financing cost (immaterial at this size).

Reward:risk summary

• Entry (blended): EUR 49.75
• Stop: EUR 51.95
• Risk per share: EUR 2.20
• Reward to TP1 (EUR 47.40): EUR 2.35 → R:R 1.07:1 (partial cover only)
• Reward to TP2 (EUR 40.75): EUR 9.00 → R:R 4.09:1 (primary)
• Reward to TP3 (EUR 35.00): EUR 14.75 → R:R 6.70:1 (stretch, conditional)

R:R on the primary objective comfortably clears the trader-skill methodology threshold ("don't set targets that imply > 3:1 reward:risk on first target; that's wishful") — note that TP2, not TP1, is the true first primary objective; TP1 is a partial cover gate, not the main target. R:R on the gate (TP1) is intentionally close to 1:1 because the gate's purpose is risk reduction, not profit booking.

Critical assumptions

These map directly onto the research-verdict's invalidation list and become the risk committee's challenge points and the journal's key_assumptions:

1. China JV (BBAC) Q2 2026 monthly retail volume runs at or below the Q1 148k pace (≈ ≤ 50k/month in CPCA April/May data).
2. The 2026-07-24 H1 print delivers at least one of: a Cars RoS guidance cut below 6%, an FCF miss vs prior-year, or noncommittal forward dividend language.
3. EUR/USD remains structurally elevated (>1.12) through the horizon. A move below 1.10 mechanically adds back EUR 700m–1.1bn EBIT; thesis weakens.
4. Technical regime persists: ADX > 40, MA stack inverted, OBV not yet diverging upward. A weekly close above EUR 51.73 on above-average volume invalidates the regime and triggers stop-out.
5. No new positive idiosyncratic catalyst (M&A activist interest, formal EU-US auto tariff exemption, China stimulus targeting premium segment).
6. Borrow remains available at reasonable cost (≤ 50 bps annualised). A buy-in or material borrow-rate spike forces an un-economic cover.

Thesis-invalidating events

These force an immediate exit regardless of price level, before the stop is hit:

1. Formal EU-US auto tariff exemption announced (any phase-in, carve-out, or rollback of the 25% US auto tariff effective 2026-04-03). Removes the largest unmitigated EBIT headwind in the bear thesis — cover the position at next session open.
2. Mercedes-Benz announces a buyback acceleration or special dividend funded from the EUR 19.4bn cash position. Signals management confidence in FCF trajectory and converts the bull's capital-return-floor argument from theoretical to active. Cover immediately.
3. Activist or strategic 13D-equivalent disclosure (an EU substantial-shareholder filing) at ≥ 5% with a public restructuring or break-up agenda. Cover immediately — re-rating risk is asymmetric.
4. China stimulus package targeting premium auto segment (e.g. purchase tax cut on vehicles ≥ EUR 40k equivalent, or NEV subsidy reinstated for foreign JVs). Cover immediately.
5. May 2026 CPCA print shows Mercedes JV monthly units ≥ 50k (i.e. running at or above Q1 quarterly pace). Triggers the verdict's named cover-and-move-to-NO-TRADE rule. Per the research-verdict, "If Mercedes monthly units run ≥ 50k (≈ 150k+ Q2 run rate), cover the short and move to NO-TRADE."
6. Borrow cost spikes above 100 bps annualised, or a buy-in notice is received. Cover and re-evaluate; if borrow remains uneconomic, the trade is closed permanently regardless of thesis status.

What I'm explicitly not doing

• Not entering at market at EUR 48.19. Giving away the bounce-fade edge that the technical regime offers; entering at EUR 49.50–50.50 improves R:R from ~2:1 to ~4:1 on the same stop and same target.
• Not using a put-spread or collar. No live Eurex options data is available (LIMITED_OPTIONS_DATA flag from options-flow analyst). Inferring IV and skew to size a derivatives structure adds execution risk without adding conviction-grade information.
• Not pair-trading long BMW / short MBG. The macro-factor analyst flagged the entire German auto sector as HEADWIND under the US tariff regime; a long BMW leg would dilute rather than isolate the Mercedes-specific thesis.
• Not sizing to the conviction-4 fixed-fractional output (10% NAV cap-bound). First-call discipline applies twice over (first decision on MBG.DE, first short-side directional call system-wide). The risk committee may legitimately argue to release this constraint up toward the cap; that's a debate the committee should have, not one I should pre-empt by oversizing.
• Not closing pre-earnings. The 2026-07-24 H1 print is the bear thesis' primary catalyst; closing pre-print discards the asymmetric-gap upside on the short. The 3.5% size is sized to absorb a +10% adverse gap.
• Not setting TP1 at the obvious profit point. EUR 47.40 is a partial-cover gate (1/3 cover, stop to entry on remainder), not a full close. The primary objective is EUR 40.75.

What would change my mind on the plan (vs the verdict)

The verdict (SHORT) is fixed input. The plan would be revised if:

• Risk committee identifies a sizing-cap input I missed (e.g. an existing correlated short already in the book that triggers the correlation cap).
• Borrow desk reports MBG.DE locate is unavailable or rate > 100 bps → downgrade plan to HEDGED (long puts) or NO-TRADE.
• Pre-trade check finds the EUR 49.50–50.50 entry zone has already been faded and price is decisively below EUR 47.40 → skip the bounce-fade entry, switch to the breakdown-trigger entry per the Entry section trigger 2.

This is research output, not investment advice. The plan is sized, stop-protected, and source-cited but is not auto-executable. The risk committee reviews next.
