1. The First Rule: Don't Lose Money

Warren Buffett's famous rule #1 is "Don't lose money." Rule #2? "Don't forget rule #1." Risk management isn't about avoiding losses—it's about controlling them. The best traders aren't the ones who win the most; they're the ones who lose the least.

🛡️ Core Concept

Risk management is the process of identifying, assessing, and controlling threats to your capital. The three pillars are: Position sizing (how much to risk per trade), Stop losses (where to exit losing trades), and Diversification (spreading risk across uncorrelated assets). Master these, and you can survive any market.

2. Position Sizing: The Math of Survival

🎓 Position Sizing: The Most Important Skill

Why Position Sizing Matters More Than Strategy

You can have a 70% win rate strategy, but if you size positions incorrectly, you'll blow up your account. Position sizing determines how much capital you risk per trade. Get it wrong, and even winning strategies fail. Get it right, and mediocre strategies survive long enough to compound.

The Deadly Math of Oversizing:
Scenario: $10,000 account, 5 consecutive losses
10% Risk Per Trade (Reckless):
Trade 1: $10,000 → $9,000 (-10%)
Trade 2: $9,000 → $8,100 (-10%)
Trade 3: $8,100 → $7,290 (-10%)
Trade 4: $7,290 → $6,561 (-10%)
Trade 5: $6,561 → $5,905 (-10%)
Final: $5,905 (-41% total) 💀
Need +69% just to break even!
1% Risk Per Trade (Professional):
Trade 1: $10,000 → $9,900 (-1%)
Trade 2: $9,900 → $9,801 (-1%)
Trade 3: $9,801 → $9,703 (-1%)
Trade 4: $9,703 → $9,606 (-1%)
Trade 5: $9,606 → $9,510 (-1%)
Final: $9,510 (-4.9% total) ✅
Need +5.2% to break even (easy!)
The asymmetry: Losing 50% requires +100% to recover. Losing 10% requires only +11%. Small losses = survivable. Large losses = catastrophic. This is why pros risk 0.5-2% per trade, never 5-10%.

Fixed Fractional Position Sizing

The most common method: risk a fixed percentage of your account on each trade. As your account grows, position size grows. As it shrinks, position size shrinks. This creates geometric compounding (up) and arithmetic drawdown protection (down).

Position Sizing Formula:
Position Size = (Account × Risk%) / Stop Loss %
Where stop loss % is distance from entry to stop
Example Calculation:
• Account size: $50,000
• Risk per trade: 1% = $500
• Entry price: $100/share
• Stop loss: $95/share (5% below entry)
• Risk per share: $100 - $95 = $5
→ Position size: $500 ÷ $5 = 100 shares
→ Total capital: 100 × $100 = $10,000 (20% of account)
If stopped out: lose $5 × 100 = $500 (exactly 1%)
✅ Advantages:
• Risk same % regardless of volatility
• Automatically scales with account
• Simple to calculate and execute
• Works for stocks, forex, crypto, options
❌ Limitations:
• Ignores asset volatility differences
• Tight stops = huge positions (risky)
• Doesn't account for correlation
• Can still overleverage on margin
Pro tip: Tighter stops don't mean less risk if you size up! $100 stock with 1% stop ($99) and 1,000 shares = same $1,000 risk as $100 stock with 10% stop ($90) and 100 shares. The stop distance determines position size, not the other way around. Never widen stops to get larger positions—that's gambling, not risk management.

Volatility-Adjusted Position Sizing

Advanced traders adjust position size for volatility. High volatility stocks (e.g., crypto, small-cap) get smaller positions. Low volatility stocks (e.g., utilities, bonds) get larger positions. This keeps total portfolio volatility constant despite holding different asset types.

ATR-Based Position Sizing:
Position Size = (Account × Risk%) / (ATR × Multiplier)
ATR = Average True Range (14-day default)
Example: Low vs High Volatility
Low Vol: $KO (Coca-Cola)
• Price: $60
• ATR: $1.20 (2% volatility)
• Risk: $1,000 (1% of $100k)
• Stop: 2 ATR = $2.40
→ Size: $1,000 ÷ $2.40 = 417 shares
= $25,020 position (25%)
High Vol: $TSLA (Tesla)
• Price: $200
• ATR: $12 (6% volatility)
• Risk: $1,000 (1% of $100k)
• Stop: 2 ATR = $24
→ Size: $1,000 ÷ $24 = 42 shares
= $8,400 position (8.4%)
Same $1,000 risk, but positions sized for volatility!
ATR Multiplier Guide:
Day trading: 1-1.5 ATR stop (tight)
Swing trading: 2-3 ATR stop (medium)
Position trading: 4-6 ATR stop (wide)

The Risk of Ruin: Consecutive Losses

Risk of ruin is the probability of losing so much capital that you can't continue trading. Even with a 60% win rate, you WILL experience losing streaks. The question: can you survive them? Position sizing determines whether a 10-loss streak is a minor setback or account death.

Probability of Consecutive Losses:
60% Win Rate Strategy:
• 2 losses in a row: 16% chance (common!)
• 3 losses in a row: 6.4% chance (happens!)
• 5 losses in a row: 1% chance (rare but real)
• 10 losses in a row: 0.01% chance (unlikely but possible)
Survival Analysis (starting $10k):
1% risk, 10 losses:
$10,000 → $9,044 (-9.6%)
✅ Still alive!
2% risk, 10 losses:
$10,000 → $8,171 (-18.3%)
⚠️ Painful but ok
5% risk, 10 losses:
$10,000 → $5,987 (-40.1%)
💀 Near ruin!
10% risk, 10 losses:
$10,000 → $3,487 (-65.1%)
☠️ Account dead
The math doesn't lie: At 1-2% risk, losing streaks are survivable speed bumps. At 5-10% risk, a single bad streak ends your trading career. Professional traders size for survival FIRST, profits SECOND. You can't compound returns if you're blown up. The tortoise beats the hare in trading.

3. Risk-Reward Ratios & Kelly Criterion

🎓 Risk-Reward: The Profitability Engine

Why Risk-Reward Beats Win Rate

Beginners obsess over win rate ("I need 80% winners!"). Pros focus on risk-reward ratio. You can be right 30% of the time and still make a fortune—if your winners are 5x bigger than your losers. Conversely, 70% win rate means nothing if your losers wipe out all your winners.

The Brutal Truth: Two Traders, Same Win Rate
❌ Trader A: High Win Rate, Low R:R
Strategy: 70% win rate, 1:1 R:R
100 trades, risk $100 each:
• 70 winners @ +$100 = +$7,000
• 30 losers @ -$100 = -$3,000
Net: +$4,000 profit
But one bad month (50% wins) = BREAKEVEN!
✅ Trader B: Low Win Rate, High R:R
Strategy: 40% win rate, 3:1 R:R
100 trades, risk $100 each:
• 40 winners @ +$300 = +$12,000
• 60 losers @ -$100 = -$6,000
Net: +$6,000 profit
Even at 30% wins (bad month) = +$3,000!
Trader B makes 50% MORE profit with 30% FEWER wins! 🤯
The lesson: Stop chasing high win rates. Chase high risk-reward ratios. A 2:1 R:R means you only need 34% win rate to break even (mathematically). 3:1 R:R? Only 26% win rate needed! This is why trend followers can be profitable with 35-40% win rates—they cut losses fast and let winners run to 5-10R+.

Expected Value: The Truth Formula

Expected value (EV) is the average amount you expect to make (or lose) per trade over many iterations. Positive EV = profitable strategy. Negative EV = losing strategy (don't trade it!). This formula combines win rate, average win, and average loss into one number.

Expected Value Formula:
EV = (Win Rate × Avg Win) - (Loss Rate × Avg Loss)
or: EV = (P(win) × R) - (P(loss) × 1)
Calculating EV: Real Examples
Example 1: Day Trading Setup
• Win rate: 55%
• Average win: $150 (3R, risking $50)
• Average loss: $50 (1R)
EV = (0.55 × $150) - (0.45 × $50)
= $82.50 - $22.50
= +$60 per trade ✅
Over 100 trades: +$6,000 profit expected
Example 2: Revenge Trading
• Win rate: 45%
• Average win: $80 (0.8R, cutting winners early)
• Average loss: $100 (1R, letting losers run)
EV = (0.45 × $80) - (0.55 × $100)
= $36 - $55
= -$19 per trade ❌
Over 100 trades: -$1,900 guaranteed loss!
Example 3: Trend Following
• Win rate: 35% (low!)
• Average win: $500 (5R, big runners)
• Average loss: $100 (1R, quick stops)
EV = (0.35 × $500) - (0.65 × $100)
= $175 - $65
= +$110 per trade ✅✅
Higher EV than 55% win rate strategy above!
Critical insight: Example 3 (35% wins) has higher EV than Example 1 (55% wins) because of the 5:1 R:R ratio! This is why professional trend followers accept low win rates—their math works. Meanwhile, revenge traders (Example 2) can win 45% and still lose money long-term due to poor R:R. Track your EV, not your win rate!

The Breakeven Win Rate Table

How high does your win rate need to be to break even at different R:R ratios? This table shows the mathematical minimum. Anything above = profitable. Anything below = losing strategy.

Breakeven Win Rate = 1 / (1 + R:R)
Common Risk:Reward Ratios
1:1 (Equal)50% win rate needed
1:1.540% win rate needed
1:233% win rate needed
1:325% win rate needed
1:517% win rate needed
1:109% win rate needed
Safety Margin Examples
1:2 R:R, 45% wins:
Need 33%, have 45% = +12% edge
EV per $1 risk: $0.35 profit ✅
1:1 R:R, 55% wins:
Need 50%, have 55% = +5% edge
EV per $1 risk: $0.10 profit ⚠️
1:3 R:R, 20% wins:
Need 25%, have 20% = -5% edge
EV per $1 risk: -$0.20 loss ❌
First example has highest edge despite medium win rate!
Strategy selection: Aim for R:R ratios where you have a realistic edge. Day traders often get 1:1.5-1:2 (need 40-33% wins). Swing traders get 1:2-1:3 (need 33-25% wins). Trend followers get 1:5-1:10 (need 17-9% wins, but hit that easily). Match your strategy to achievable win rates, don't force high win rates with bad R:R!

Kelly Criterion: Optimal Position Sizing

The Kelly Criterion is a formula from gambling theory (1956, Bell Labs) that calculates the optimal bet size to maximize long-term growth. It considers both win rate AND risk-reward ratio. Kelly answers: "What % of my capital should I risk to grow fastest without going broke?"

Kelly Criterion Formula:
Kelly % = (P × R - Q) / R
Where: P = win probability (0.6 = 60%)
Q = loss probability (1 - P)
R = risk-reward ratio (win/loss)
Kelly Examples: What % to Risk?
Example 1: Strong Edge
• Win rate (P): 60%
• R:R ratio (R): 2:1
Kelly = (0.6 × 2 - 0.4) / 2
= (1.2 - 0.4) / 2
= 40% of capital per trade!
⚠️ Full Kelly is aggressive—use half Kelly = 20%
Example 2: Moderate Edge
• Win rate (P): 45%
• R:R ratio (R): 2:1
Kelly = (0.45 × 2 - 0.55) / 2
= (0.9 - 0.55) / 2
= 17.5% of capital per trade
Half Kelly = 8.75% (still aggressive)
Example 3: No Edge
• Win rate (P): 30%
• R:R ratio (R): 2:1
Kelly = (0.3 × 2 - 0.7) / 2
= (0.6 - 0.7) / 2
= -5% (NEGATIVE Kelly!)
❌ Don't trade this setup—no edge!
⚠️ Why Pros Use Fractional Kelly:
• Full Kelly (100%): Maximum growth but insane volatility. 50% drawdowns common!
• Half Kelly (50%): 75% of growth, 50% of volatility. Most popular among pros.
• Quarter Kelly (25%): 50% of growth, 25% of volatility. Conservative institutions use this.
Example: If Kelly says 20%, most traders risk 5-10% (quarter to half Kelly).
Real-world application: Kelly assumes perfect knowledge of P and R, which you never have. Your estimated 60% win rate might actually be 55% (bad luck) or 50% (strategy degraded). That's why using half Kelly or less protects you from estimation errors. Plus, Kelly ignores correlation between trades—if you have 5 positions sized at full Kelly, you're massively overexposed!

4. Portfolio Protection Strategies

🎓 Hedging: Insurance for Your Portfolio

What is Hedging? (And Why It's Not Free)

Hedging is taking an offsetting position to reduce portfolio risk. Think of it as insurance: you pay a premium (drag on returns) to protect against catastrophic loss (market crashes). Like car insurance, you hope you never need it—but you're glad you have it when disaster strikes.

Hedge Types & Costs:
1. Put Options (Tail Risk Insurance)
Mechanism: Buy SPY puts 10-20% out-of-the-money
Cost: 1-3% annually (premium decay)
Benefit: Massive gains in crashes (-30% market = +500% on puts)
Example: March 2020 COVID crash, SPY $340 → $220 (-35%), puts bought at $1 went to $50 (+4,900%)
2. Inverse ETFs (Daily Hedges)
Mechanism: Hold 10-25% in SQQQ, SPXU, etc.
Cost: 2-4% annually (contango, management fees)
Benefit: Daily inverse exposure, automatic rebalance
⚠️ Warning: Path-dependent, decays in sideways markets!
3. Long Volatility (VIX Instruments)
Mechanism: Buy VIX calls or UVXY shares
Cost: 5-10% annually (volatility premium)
Benefit: Explodes when VIX spikes (calm 15 → panic 80)
Best for crisis events: 2008 financial crisis, 2020 COVID, 2022 inflation panic
4. Asset Class Diversification
Mechanism: Hold bonds, gold, cash alongside stocks
Cost: 0-2% annually (lower returns from bonds)
Benefit: Natural hedge, bonds/gold up when stocks down
Classic 60/40 portfolio: -32% in 2008, vs -57% for 100% stocks
The tradeoff: Hedges cost money. If you hedge 25% of your portfolio with puts costing 2% annually, that's -0.5% drag on total returns. Over 10 years with no crash, you've paid 5% in "insurance premiums." But if a 2008-style crash happens (you're saved from -40% loss), the hedge pays for itself 8x over. It's insurance, not alpha.

When to Hedge: Timing the Insurance

Static hedging (always hedged) is expensive. Dynamic hedging (hedge when risk is high) saves money. But timing hedges is hard—you're essentially market timing. Most pros use a hybrid: light static hedge (5-10%) + increase to 20-30% when danger signals flash.

Hedge Signals: When to Increase Protection
✅ ADD Hedges When:
• VIX < 15 (complacency = danger)
• Market up 20%+ YTD (overextended)
• Valuation: S&P 500 P/E > 25x (expensive)
• Fed tightening cycle (rate hikes kill bull runs)
• Yield curve inverts (recession signal, 6-18 months lead)
• Credit spreads widening (corporates stressed)
• Margin debt at all-time highs (leverage = fragile)
Example: Jan 2022 had ALL signals (VIX 16, SPY +27% 2021, P/E 30x, Fed tightening). Hedging then saved you from -25% crash!
❌ REMOVE Hedges When:
• VIX > 35 (panic = bottoming process)
• Market down 20%+ from highs (bear already here)
• Valuation: S&P 500 P/E < 16x (cheap)
• Fed pivoting to cuts (liquidity coming)
• Yield curve steepening (recovery ahead)
• Sentiment: extreme bearishness (contrarian buy)
• Insider buying surges (smart money accumulating)
Example: March 2020 VIX 82, SPY -35%, everyone panicking. That was TIME TO REMOVE HEDGES and buy stocks at discount!
📊 The Hedge Ladder Strategy:
• 0% hedge: Bull market, VIX <20, valuations fair, Fed accommodative
• 10% hedge: Late bull, VIX 15-20, valuations elevated, Fed neutral
• 25% hedge: Topping, VIX <15, valuations extreme, Fed hawkish
• 50% hedge: Bear confirmed, protecting remaining gains, waiting for bottom
Scale hedge % with market conditions—don't be all-in or all-out!
Reality check: Perfect timing is impossible. You'll add hedges "too early" (lose money on insurance while market rallies) and remove them "too late" (lose money in early stages of crash). That's OK! Hedging is about REDUCING risk, not eliminating it. Even being 50% right on timing improves risk-adjusted returns significantly.

Correlation: The Hidden Risk

Correlation measures how two assets move together (1.0 = perfectly together, 0 = independent, -1.0 = perfectly opposite). Diversification ONLY works with low correlation (<0.3). High correlation = fake diversification.

Correlation Table: S&P 500 vs Other Assets
High Correlation (0.7-1.0) ❌ Poor Diversification
• Nasdaq 100:0.95 correlation
• Russell 2000 (small-cap):0.88 correlation
• International stocks (EAFE):0.82 correlation
• REITs (real estate):0.75 correlation
All crash together! 2008: S&P -57%, Nasdaq -54%, Russell -38%, EAFE -45%
Medium Correlation (0.3-0.7) ⚠️ Some Diversification
• Emerging markets:0.65 correlation
• Corporate bonds:0.50 correlation
• Commodities (CRB Index):0.40 correlation
Helps a bit, but not enough for true protection
Low/Negative Correlation (-1.0-0.3) ✅ BEST Diversification
• US Treasury bonds (TLT):-0.20 correlation
• Gold (GLD):0.10 correlation
• Managed futures:-0.15 correlation
• Long volatility (VIX):-0.75 correlation
These ZIG when stocks ZAG! 2008: S&P -57%, TLT +34%, Gold +4%, VIX +300%
⚠️ The Correlation Trap:
Holding $AAPL, $MSFT, $GOOGL, $NVDA, $META feels diversified (5 stocks!). But they're all tech with 0.80+ correlation. In 2022 tech crash, ALL tanked together: AAPL -27%, MSFT -29%, GOOGL -39%, NVDA -50%, META -64%.
True diversification: Hold stocks + bonds + gold + managed futures. Low correlation BETWEEN asset classes, not within.
Crisis correlation: Beware—correlations INCREASE during crashes (everything sells off together as liquidity dries up). 2008 saw normally uncorrelated assets move together. Only truly negative correlation assets (long vol, inverse ETFs, cash) held up. This is why tail risk hedges (put options, VIX) are so valuable despite their cost—they're the ONLY things that truly work when you need them most.

5. Key Takeaways

💰

The 1% Rule

Never risk more than 1-2% of your capital on a single trade. This simple rule keeps you in the game even during 10+ consecutive losses. Risk 10%? Just 5 losses = -40% drawdown.

⚖️

Risk-Reward is Everything

Only take trades with minimum 2:1 reward-to-risk. With 3:1 ratios, you can win just 40% of trades and still profit. Your win rate matters less than your risk-reward ratio.

🎲

Kelly Criterion for Sizing

Use Kelly Criterion to calculate optimal position size, but use half-Kelly or less in practice. Full Kelly maximizes growth but creates massive volatility and drawdowns.

🛡️

Hedging Costs Money

Portfolio hedging protects against crashes but reduces returns in bull markets. Use hedges when valuations are stretched or volatility is abnormally low (VIX < 15).

🔗

Correlation Kills Diversification

Holding 10 tech stocks isn't diversification—they're highly correlated (0.8+). True diversification requires low correlation (<0.3) between assets: stocks, bonds, commodities, currencies.

📊

Expect Drawdowns

Even the best strategies face 20-30% drawdowns. Use Monte Carlo simulations to prepare mentally. If you panic and stop following your system during drawdowns, all the math becomes useless.
