InvAssistant

Multi-asset investment portfolio management framework — current version v2.1.2 (2026-06-06). Core philosophy: portfolio before stock-picking, discipline before inspiration. Rules are guardrails, not cages.

1. Asset Classification (Three Tiers)

This is the foundation of v2.1+. Different assets use different exit logic.

Tier	Definition	Rules	When To Sell
A-Class (Platform Core)	Long-moat, cash-flow-stable platform companies	HOLD, no trailing stop; DCA entries	Only 3 reasons: ① fundamental deterioration (2+ quarters) ② narrative change ③ portfolio limit breach
B-Class (High-Beta Cyclical)	High-beta, narrative-driven growth	Trailing stop + position management	QMS < 40 triggers review
C-Class (Low-Volatility Income)	Broad-market/dividend ETFs, utilities	DCA + rebalancing	No active timing

Key insight: A-class price drawdowns ≠ sell signals. Using trailing stops on A-class washes out long-term compounders.

2. Portfolio Risk Controls: 7 Red Lines (Non-Overridable)

#	Rule	Threshold	Action
1	Single position concentration	>25%	Reduce to ≤20% within 3 months
2	Single sector concentration	>35%	Reduce to ≤30% within 3 months
3	AI single-narrative	>50%	Reduce to ≤40% within 6 months
4	Portfolio drawdown (mild)	>-12%	Halve satellite positions
5	Portfolio drawdown (severe)	>-15%	Total position ≤60%
6	VIX systemic risk	≥40	Reduce total to ≤50%
7	Pre-Trade Log compliance	<100%	Log immediately

3. US Stock Strategy

Entry Modes

Mode	Applies To	Logic
A (Panic Mispricing)	B-Class (TSLA/NVDA extreme)	Emotion release + technical support + VIX <25
B (Trend Confirmation)	B-Class	Price > MA50 + breakout + fundamentals + valuation
C (Rebalancing)	Portfolio-level	Triggered by Red Lines 1-3 only
D (A-Class Candidate Zone Entry)	Candidate pool (non-tech diversification targets)	Callback-based, no observation delay

Mode D: A-Class Candidate Zone Entry (v2.1.1)

Applied to new A-class candidates before they join the core portfolio. Designed to solve the "observation delay misses entry window" problem.

Principle: No observation delay. A -10% pullback from 20D high on an A-class candidate is itself a complete entry signal — the underlying moat business doesn't change with share price.

Zone	Trigger	Allocation	Execution
First tranche	-10% from 20D high	50% of target	Execute immediately
Add	-15% (or >3% further drop after first)	30%	Execute on trigger
Final	-20% (or 5+ days sideways without new low)	20%	Within zone

Constraints: total ≤2% portfolio; MCO requires PE percentile <60%; no chasing after rebound.

Why Different from TSLA Mode A

TSLA (B-Class satellite) needs bottom confirmation — the drop might be fundamentally justified. A-class candidates (moat compounders) only need price confirmation — a -10% discount on a quality business is self-evidently an opportunity.

4. A-Share Strategy (3-Condition Engine)

All three conditions must pass for entry:

Condition	Standard
① Engine score ≥80 + 3 consecutive days on list	Core selection pool
② Current price ≤ dynamic target (with floor)	`max(static×0.85, min(static, MA20×0.95))`
③ MA20 flat or turning up	MA20 delta ≥ -0.05

Flex window: 2/3 conditions met + 3rd deviation ≤10% → half-position trial. Time stop: 6 months max in selection pool without entry → forced review.

5. HK Stock Strategy

Source	Framework
Actively bought	Follow A/B/C classification rules
Company allocation/incentive	Warning line + reduction framework (not hard stop)

Warning line (not hard stop): Triggers 48h review upon breach. Time limit: 18 months post-vesting with remaining position → unconditional full exit.

6. QMS Scoring (4-Factor)

text

QMS = 0.35 × Earnings Trend
    + 0.25 × Sector Relative Strength
    + 0.25 × EPS Revision
    + 0.15 × Price Structure

Score	Meaning	Action
≥70	High quality + good timing	Hold / observe entry
50-70	Healthy, not at entry point	HOLD
<50	Quality or timing issues	No new positions
<40	Review exit queue	Evaluate reduction (B-Class only)

Boundary: QMS is entry reference for A-Class, NOT an exit trigger. Only B-Class uses QMS <40 as reduction signal.

7. Monthly KPIs

KPI	Threshold	Type
Monthly turnover rate	≤15%	Red line
Pre-Trade Log compliance	=100%	Red line
A-Class sold on price volatility	=0	Red line
Panic-period reduction (VIX≥30)	=0	Red line
System execution rate	≥80%	KPI

8. Hard Rules Summary

Asset classification determines action semantics: A-Class no trailing stop, B-Class uses trailing stop
Held vs. watchlist semantics must not be mixed
A-share 3-condition is a filter: all pass → entry (flex window = 2/3 + deviation + half-size)
US B-Class dual-mode: Mode A (3 red lines all pass) / Mode B (4 conditions all pass)
Unfilled ≠ holding: portfolio data must reflect actual positions
Never fabricate data: all indicators must come from live data sources
A-Class only sells on 3 fundamental reasons (never price)
7 Red Lines triggered = must follow, no override
Allocation/incentive positions do not use standard stops
Every override must be logged
Max 2 overrides per ticker per quarter; 3rd is void
Daily self-check: 5 questions, all "no" = no trade today

9. Data Sources

Data Type	Primary	Fallback
US stock quotes/technicals	westock-data	Yahoo Finance
A-share K-line/technicals	westock-data	AKShare
HK stock quotes	westock-data	Yahoo Finance
VIX	westock-data	Yahoo Finance
North-bound capital	NeoData	AKShare
Financial reports/consensus	westock-data	NeoData

10. Common Mistakes

#	Mistake	Fix
P1	Treating A-Class as B-Class (v2.0's worst error)	Ask "Is this A or B?" before acting
P2	Writing "reduce" for watchlist stocks	Ask "Is this held?" first
P3	Cross-market strategy pushed to sub-pages	Cross-market → main page; specific rules → sub-page
P4	LaTeX `$xxx` swallows first digit	Use `US$` / `HK$` / `¥` / `\$`
P5	Wrong code block language (`'plain'`)	Must use `'plain text'` (with space)
