Capital Preservation is Everything

The math of trading is asymmetric and brutal: a 50% loss requires a 100% gain just to get back to breakeven. This is why every professional trader's first priority isn't finding winners — it's controlling losses.

You can have a strategy with a 40% win rate and still be profitable. You cannot survive a strategy with no stop-losses, no matter how high your win rate is. One catastrophic loss erases months of gains.

Stop-Losses: Your Only Real Insurance

A stop-loss is a pre-defined exit price that closes your position if the trade moves against you. There are three practical approaches:

• Fixed Percentage Stop: Exit at -2% from entry regardless of anything else. Simple and consistent, but ignores the stock's actual volatility.
• ATR-Based Stop: Set your stop at 1.5-2x the Average True Range (ATR?) below your entry. If a stock has an ATR? of $3.50, your stop is $5.25 below entry. This respects how wildly that particular stock naturally swings.
• Technical Stop (Professional Method): Place your stop just below the most recent structural support or the low of the entry candle. If the stock breaks that level, your original thesis is structurally invalid.

The technical stop is preferred because it's logic-based. You're not exiting because a stock moved an arbitrary -2%; you're exiting because the setup that justified the trade no longer exists.

Critical rule: Set your stop-loss before entering the trade, not after. And never, ever move it wider to avoid being stopped out — that's how $200 losses become $2,000 losses.

Position Sizing: The Math That Keeps You Alive

Position sizing answers: given my stop-loss placement, how many shares can I buy?

The rule: risk no more than 1-2% of total account equity on any single trade.

With a $10,000 account at 1% risk:

• Maximum risk per trade = $100
• If your stop is $2.00 below entry → you can buy 50 shares ($100 ÷ $2.00)
• If your stop is $5.00 below entry → you can buy 20 shares ($100 ÷ $5.00)

Notice what this does: it automatically forces you to take smaller positions when your stop is farther away. Sloppy setups with wide stops get small size. Clean setups with tight stops get larger size. This is the correct behavior.

At 1% risk per trade with a 50% win rate, you can sustain 50 consecutive losses before your account drops to $5,950. That's survivable. Traders risking 10% per trade can wipe out their account in 10 bad trades.

Risk-to-Reward: The Expectancy Game

Win rate alone is meaningless without context. A 70% win rate with a 1:0.5 R/R (risking $2 to make $1) is a losing strategy. A 30% win rate with a 1:3 R/R is a winning strategy.

The expectancy formula: (Win Rate × Avg Win) − (Loss Rate × Avg Loss)

At 1:3 Risk-to-Reward:

• 30% win rate: (0.30 × $3) − (0.70 × $1) = $0.90 − $0.70 = +$0.20 per dollar risked
• 25% win rate: Breakeven
• 20% win rate: Losing strategy

This means at a 1:3 R/R ratio, you only need to be right 25% of the time to not lose money. Professional traders rarely enter trades with less than a 1:2 R/R, and often require 1:3 or better.

Never enter a trade where the potential reward is less than 1.5x your risk. If you can't find a logical profit target that justifies the risk, the trade isn't worth taking.

Portfolio Heat: The Hidden Risk

Even with perfect per-trade position sizing, you can blow up through correlation.

Owning AMD, NVDA, INTC, and SMCI simultaneously isn't four independent trades — it's one large bet on semiconductor sentiment. When the sector rotates, all four move together.

Professionals track portfolio heat: the total percentage of the account actively at risk across all open positions. A common limit is 5-8% total heat regardless of how many individual positions you hold.

Scaling Out: Locking Gains Without Exiting

You don't have to choose between holding and selling everything. Scaling out lets you do both:

1. Enter a full position at your setup level
2. Sell 50% at your first target (+1R or +1.5R)
3. Move your stop-loss to breakeven on the remaining 50%
4. Let the runner go with no risk — you've already locked a profit

At this point you have a risk-free trade. Even if the remaining position gets stopped out at breakeven, your overall trade is profitable from the first partial exit.
