Introduction: You've Found A Great Stock - Now What?
You've done your homework:
- ✓ Analyzed the financial statements (Part 1)
- ✓ Calculated valuation ratios (Part 2)
- ✓ Assessed competitive moats and growth (Part 3)
You've found a quality company at a fair price with strong growth prospects. Now the hard questions:
- When exactly should I buy it?
- How much should I invest?
- When do I sell?
- How do I build a balanced portfolio?
This final part gives you the practical tools to execute your investment strategy.
PART 1: READING STOCK CHARTS - Finding The Right Entry Point
Why Charts Matter
Fundamental analysis (Parts 1-3) tells you WHAT to buy.
Technical analysis tells you WHEN to buy it.
Even a great stock can drop 20-30% after you buy if your timing is poor. Charts help you avoid buying at peaks and find better entry points.
Understanding Trends
GRAPH 13: The Three Trends
UPTREND (BUY ZONE)
- Price making higher highs and higher lows
- Each dip is followed by a bigger rally
- Action: Buy dips, hold
SIDEWAYS/CONSOLIDATION
- Price bouncing between support and resistance
- No clear direction
- Action: Wait for breakout
DOWNTREND (AVOID ZONE)
- Price making lower highs and lower lows
- Each rally is followed by bigger drop
- Action: Don't buy, or sell if you own
The Golden Rule: Only buy stocks in clear uptrends. Never try to "catch a falling knife" in downtrends.
Support And Resistance Levels
SUPPORT: A price level where the stock tends to stop falling and bounce back up (buyers step in)
RESISTANCE: A price level where the stock tends to stop rising and pull back (sellers step in)
GRAPH 14: Support & Resistance Levels
Key Insight:
• Buy near support (£100-£105) = lower risk, better entry
• Avoid buying near resistance (£115-£120) = likely to drop
• Breakout above £120 = new uptrend starting (buy signal)
• Break below £100 = downtrend starting (sell signal)
Real Example: Apple Stock (2023)
| Date |
Price |
Technical Signal |
Decision |
| Jan 2023 |
£125 |
At resistance, overbought |
❌ DON'T BUY - wait |
| Mar 2023 |
£150 |
Broke through resistance strongly |
✓ BUY - breakout confirmed |
| May 2023 |
£180 |
At new resistance, extended |
❌ DON'T BUY - overextended |
| Jul 2023 |
£165 |
Pulled back to old resistance (now support) |
✓ BUY - healthy pullback |
| Sep 2023 |
£145 |
Sharp drop, broke support |
❌ SELL - trend broken |
The Lesson:
• Buying at £150 (breakout) or £165 (pullback) = good entries
• Buying at £125 or £180 (resistance) = poor timing, likely to drop
• Don't chase prices - wait for pullbacks to support
Moving Averages: The Trend's Best Friend
Moving Average (MA): The average stock price over X days, plotted as a smooth line.
Most Common:
- 50-day MA: Short-term trend
- 200-day MA: Long-term trend
GRAPH 15: Moving Averages In Action
BULLISH SIGNALS (Time to buy):
- ✓ Price above both MAs = strong uptrend
- ✓✓ 50-day MA crosses above 200-day MA = "Golden Cross"
- ✓ Price pulls back to 50-day MA and bounces = healthy dip
BEARISH SIGNALS (Time to sell):
- ❌ Price below both MAs = downtrend
- ❌❌ 50-day MA crosses below 200-day MA = "Death Cross"
- ❌ Price breaks below 200-day MA = long-term trend broken
Volume: The Truth Detector
Volume = Number of shares traded that day
Why it matters: Price moves mean MORE when accompanied by high volume.
The Rules:
- Price up + high volume = Strong buying, sustainable move ✓
- Price down + high volume = Strong selling, serious trouble ❌
- Price up + low volume = Weak move, likely to reverse
- Price down + low volume = Not much concern, could bounce

PART 2: ENTRY STRATEGIES - Optimal Ways To Buy
Strategy 1: The Dip Buy Low Risk
When to use: Stock in strong uptrend, pulls back to support
How it works:
- Identify strong uptrend (price above 50 & 200-day MA)
- Wait for pullback to support level or moving average
- Buy when price bounces off support
- Set stop-loss below support
Example:
- Apple trending up, trading at £180
- Pulls back to £165 (50-day MA)
- You buy at £166
- Set stop-loss at £160 (below MA)
- Risk: £6 per share (3.6%)
- If it works, ride it to £190+
Best for: Conservative investors, buying in established trend at support
Strategy 2: The Breakout Buy Moderate Risk
When to use: Stock breaks through major resistance on high volume
How it works:
- Stock consolidating at resistance for weeks/months
- Price breaks above resistance with strong volume
- Buy on the breakout or slight pullback
- Set stop-loss below breakout point
Example:
- Stock stuck at £100 resistance for 3 months
- Breaks to £105 on 3x normal volume
- You buy at £106
- Set stop-loss at £98
- Risk: £8 per share (7.5%)
- Target: £125+ (new territory)
Best for: Growth investors, higher risk/higher reward
Strategy 3: The Dollar-Cost Average Low Risk
When to use: You love the stock but not sure about timing
How it works:
- Divide your investment into 3-5 equal parts
- Buy one part now
- Buy additional parts over 4-8 weeks
- Average entry price, reduce timing risk
Example:
- You want to invest £5,000 in Microsoft
- Buy £1,000 now at £350
- Buy £1,000 next month at £340 (price dropped)
- Buy £1,000 month 3 at £360 (price rose)
- Buy £1,000 month 4 at £355
- Buy £1,000 month 5 at £365
- Average cost: £354 (smooth out volatility)
Best for: Beginners, spread out risk, emotional comfort

PART 3: EXIT STRATEGIES - When To Sell
The Hardest Part Of Investing
Buying is easy. Selling is hard. Here's when to exit:
Reason 1: Price Target Hit
Set targets based on valuation:
- If fair value is £150 and you bought at £100
- Sell 50% at £140-150 (lock in gains)
- Let rest run with trailing stop
Reason 2: Fundamental Deterioration
From Part 3 - Red flags appearing:
- Losing market share
- Margins compressing
- Moat eroding
- Better opportunities elsewhere
Action: Sell immediately, don't wait for recovery
Reason 3: Technical Breakdown
Price action says something's wrong:
- Breaks below major support
- Death Cross (50-MA crosses below 200-MA)
- High-volume selling
Action: Sell and ask questions later
Reason 4: Portfolio Rebalancing
Position became too large:
- One stock now >20% of portfolio
- Concentration risk too high
- Trim to maintain balance
The Trailing Stop-Loss Strategy
What it is: A stop-loss that moves up as the stock rises
How it works:
- Buy stock at £100
- Set 15% trailing stop (will sell if drops 15% from peak)
- Stock rises to £150 → stop is now at £127.50
- Stock rises to £180 → stop is now at £153
- Stock drops to £152 → YOU'RE STILL HOLDING
- Stock drops to £151 → AUTOMATICALLY SOLD at £153
Benefits:
• Locks in gains as stock rises
• Removes emotion from selling
• Lets winners run
Best for: Growth stocks in strong uptrends

PART 4: BUILDING YOUR PORTFOLIO
Portfolio Construction Basics
Don't put all eggs in one basket. Here's how to diversify properly:
The Core-Satellite Strategy
CORE (60-70% of portfolio):
- Large, stable companies
- Proven business models
- Lower volatility
- Examples: Microsoft, Apple, Visa, Johnson & Johnson
SATELLITE (30-40% of portfolio):
- Higher growth potential
- Smaller companies
- More volatile
- Examples: Emerging tech, small-caps, international
GRAPH 19: Portfolio Allocation Model (£10,000 Example)
Sector Diversification
Don't concentrate in one industry. Spread across sectors:
| Sector |
Allocation |
Example Companies |
| Technology |
20-25% |
Apple, Microsoft, Google |
| Healthcare |
15-20% |
Pfizer, J&J, UnitedHealth |
| Financials |
10-15% |
Visa, JPMorgan, BlackRock |
| Consumer |
10-15% |
Amazon, Nike, Coca-Cola |
| Industrials |
5-10% |
Boeing, Caterpillar |
| Energy |
5-10% |
ExxonMobil, Renewable companies |
| Other |
15-20% |
REITs, International, Emerging |
Why diversify sectors?
• If tech crashes, healthcare might hold up
• Economic cycles affect sectors differently
• Reduces portfolio volatility
GRAPH 20: Sector Allocation
Position Sizing: How Much To Invest In Each Stock
The Rules:
1. No single stock >10% of portfolio (20% max for highest conviction)
- If £10,000 portfolio → max £1,000-2,000 per stock
- Prevents disaster if one stock crashes
2. Start small, add on strength
- Buy 50-60% of intended position first
- Add more if thesis proves correct
- Allows you to average up with conviction
3. Size by conviction and risk
- High conviction, low risk: 8-10% position
- High conviction, high risk: 3-5% position
- Moderate conviction: 2-4% position
- Speculative: 1-2% position

PART 5: RISK MANAGEMENT
The Rules That Protect Your Capital
Rule 1: Never Risk More Than 2% On One Trade
If you have £10,000:
- Max loss per trade = £200
- If you buy at £100 with stop at £96 (4% stop)
- Position size = £200 ÷ £4 = 50 shares = £5,000 position
This limits damage from any single bad decision.
Rule 2: Use Stop-Losses
Mental stops don't work - emotions take over.
Set actual stop-loss orders:
- 10-15% for large-cap stocks
- 15-20% for small-caps/growth
- 5-10% for trading positions
Rule 3: Don't Average Down On Losers
- WRONG: Stock drops 20% → buy more to "average down"
- RIGHT: Stock drops past your stop → sell and move on
Exception: Only average down if fundamentals improved and thesis still intact
Rule 4: Let Winners Run, Cut Losers Short
Most investors do the opposite:
- Sell winners too early (lock in small gains)
- Hold losers hoping for recovery (let losses balloon)
Do this instead:
- Keep winners with trailing stops
- Cut losers at predetermined stop-loss
