Concentrated Portfolio Rules — Quality > Quantity
Conventional wisdom: ২০-৩০ stocks portfolio = safe। Minervini এই philosophy reject করেন। তাঁর approach: ৪-৮ stocks max, focused, A+ setup only। কেন? Math এবং practical reasons।
কেন ৪-৮ Position
Quality Argument
Market-এ A+ setup খুব rare। DSE-তে যেকোনো সময়ে ৫-১৫টা stock Trend Template + VCP base + leadership pass করে। আপনি ৩০ stock-এ portfolio চাইলে, ১৫টা mediocre setup add করতে হবে।
Math Argument
- ৩০ stock-এ একটা ১০০% winner = ৩.৩% portfolio gain
- ৬ stock-এ একই winner = ১৬.৭% portfolio gain
- ৫x impact difference
- Concentrated portfolio leverages winners
Monitoring Argument
৩০ stock daily monitor অসম্ভব। ৪-৮ stocks-এর প্রতিটা চার্ট, fundamentals, news daily check feasible।
Position Allocation Framework
Initial Position
Typical Position
Maximum Position
Cash Reserve
Regime-Based Position Count
- Confirmed Bull: ৬-৮ positions, fully deployed
- Late Bull / Mixed: ৪-৬ positions, defensive
- Bear: ০-৩ positions, cash priority
- Recovery (post-FTD): ১-৩ positions, slow build
Sector Concentration Limits
একই sector-এ ২+ position avoid। Sector tank করলে concentrated risk।
- Max ১ position per sector
- Exception: large sectors (banking, pharma) — max ২
- Total sectors covered ৪-৬ ideally
- Defensive + growth + cyclical mix preferred
Position Lifecycle
When to Add New Position
Existing position-এ profit + free capital। কখন new position যোগ?
- Existing position-এ scale-out tier 1 done — capital free
- Cash reserve available
- A+ setup signal market-এ
- Different sector (concentration cap respect)
- Total positions still < max for regime
Never Average Down — Re-emphasized
Concentrated portfolio-এ average down catastrophic। ১০% portfolio loser-এ আরো ৫% add মানে ১৫% concentration on losing thesis। Account destruction।
- Stop hit = exit, no add
- Add only on profit (pyramid up)
- Average down = systemic risk multiplier
DSE Liquidity Constraint
Concentrated portfolio + DSE liquidity = balance চাই।
- Position size ≤ daily volume-এর ১%
- Exit liquidity guaranteed
- Small-caps-এ position smaller রাখা
- Large-caps (SQURPHARMA, GP) standard size acceptable
Common Mistakes
Diluting with mediocre setups
Same sector concentration
Refusing to exit losers
Position size inconsistent
Bear market full deployment
Sample Bull Market Portfolio
১৫ লাখ টাকা portfolio, bull market scenario:
| # | Stock | Sector | % Portfolio | Status |
|---|---|---|---|---|
| 1 | SQURPHARMA | Pharma | ১৫% | +২২%, tier 1 done |
| 2 | BRACBANK | Banking | ১২% | +৮%, holding |
| 3 | GP | Telecom | ১০% | +১৫%, holding |
| 4 | BEXIMCO | Conglomerate | ১২% | +৫%, recently added |
| 5 | OLYMPIC | FMCG | ৮% | Initial position |
| 6 | BSRMSTEEL | Steel | ৮% | +১২%, holding |
| 7 | — | Cash | ৩৫% | Available |
৬ positions, ৬ different sectors, প্রতিটা ৮-১৫% range, ৩৫% cash — balanced concentrated portfolio।
Bear Market Portfolio
একই scenario, bear regime:
| # | Stock | % Portfolio | Reason |
|---|---|---|---|
| 1 | SQURPHARMA | ১০% | Strong stage 2 holdout |
| 2 | Cash | ৯০% | Defensive mode |
Bear-এ aggressive cut। Best stocks-ই hold। বাকি cash। FTD-র অপেক্ষা।
চূড়ান্ত কথা
Concentrated portfolio counterintuitive। বেশিরভাগ trader ভাবে “more stocks = safer”। কিন্তু math এবং execution reality উল্টো।
৪-৮ A+ setup, প্রতিটা ১০-১৫% portfolio, ৪-৬ different sectors, cash reserve — Minervini-র framework। Apply করুন। Account performance dramatically change হবে।
