Step 7: Risk Management and Complete Decision Tree

Series "Beginner's Guide to Stock Trading" — final part 7/7.

Previous: Step 6 — Selecting Stocks Based on 5 Pillars and Smart Money Confluence. Now we'll put it all together.

You've reached the end of the series. In steps 1–6, we covered what to trade and when: you found your style, chose a strategy, learned to read market phases, sentiment, and fear, and finally how to select specific stocks based on the five pillars and the confluence of "smart money."

And now I'll tell you something you should learn first, even though it comes last:

The stocks you pick matter much less than how you manage risk.

Paul Tudor Jones — one of the greatest traders in history — summed it up in one sentence: "It doesn't matter if you're right. It matters how much you make when you're right and how much you lose when you're wrong." This is the whole secret. Two people can pick the exact same stocks, and one will get rich while the other will go broke — because one manages risk and the other doesn't.

This part is about the most important skill. And at the end, you'll get a decision tree — a 10-step checklist that ties the entire series into one repeatable habit.

Part 1: Risk Management as Skill #1

Why Defense Comes Before Offense

A beginner thinks: "How much can I make?" A professional thinks: "How much can I lose?" That's the whole difference between a professional and an amateur.

The reason is mathematical and it's brutal. Look at the math of return:

You Lose	How Much You Need to Earn to Break Even
−10 %	+11 %
−20 %	+25 %
−33 %	+50 %
−50 %	+100 %
−75 %	+300 %
−90 %	+900 %

Do you see the asymmetry? Losses and gains are not symmetrical. If you lose half of your account, earning 50% won't suffice — you need to earn 100% just to get back to where you started. If you drop by 90%, you need +900%, which practically never happens.

★ Insight: A big loss isn't "bad luck," it's a mathematical trap. Every percentage you lose is more expensive to regain than it was to lose. Therefore, the first rule is: don't let a big loss occur. Small controlled losses are the cost of doing business. Big uncontrolled losses are the end of business.

"Survive First" — Who Survives, Wins

Markets move in cycles (remember Step 4). After every bear market comes a bull market. After every crisis comes recovery. The only way not to miss out on that recovery is to live to see it with capital.

Ed Thorp, a mathematician who beat both roulette and Wall Street, said the main goal isn't to maximize profit — it's to avoid account destruction (risk of ruin). If you burn out, you're out of the game forever, no matter how good your idea was. The market won't give you a second chance if you have nothing to play with.

Risk of ruin = the probability that you'll lose so much capital that you can't continue. Your job as a trader isn't to "be right" — it's to keep this probability close to zero so you're still in the game when the big opportunity comes.

Part 2: Position Size — How Much to Bet

Position sizing is, according to Van Tharp (Trade Your Way to Financial Freedom), the most underrated part of trading and at the same time the one that most determines the outcome. It's not about which stock you buy — it's about how much of your account you put into it.

The 1–2% Risk per Trade Rule

The simplest and most robust rule used by professionals: never risk more than 1–2% of your account on a single trade.

Note — "risking 1%" does not mean putting 1% of your account into a stock. It means that if the trade doesn't work out and you exit at your stop level, you'll lose only 1% of your account. That's the difference between position size and risk size.

Example calculation (fixed-fractional sizing):

• Account: 100,000 CZK
• Risk per trade: 1% = 1,000 CZK (that's how much you can lose)
• Stock costs 200 CZK, your stop level is 184 CZK (−8%)
• Risk per 1 stock = 200 − 184 = 16 CZK
• Number of stocks = 1,000 CZK ÷ 16 CZK = 62 stocks
• Total position = 62 × 200 = 12,400 CZK (i.e., 12.4% of the account)

Notice: you put 12.4% of your account into the position, but you're only risking 1% because the stop is close. If the stop were further away (wider), you'd buy fewer stocks. Position size adjusts to the stop distance — that's the whole magic. The riskier the entry, the smaller the position.

★ Insight: This rule keeps you alive even in a losing streak. If you risk 1% per trade, you'd need 20 losses in a row to lose 18% of your account. At 10% per trade, a few unlucky trades would put you in the mathematical trap from the table above. Small bets = long breath.

Kelly Criterion — and Why Only Half

Ed Thorp popularized the Kelly Criterion — a formula that tells you what optimal portion of capital to bet so your account grows as fast as possible in the long run:

Kelly % = W − [ (1 − W) / R ]

where W = probability of winning (win rate) and R = ratio of average gain / average loss.

Example: you win in 50% of cases (W = 0.5) and your average gain is 2× larger than your average loss (R = 2):
Kelly = 0.5 − (0.5 / 2) = 0.25 → the formula says "bet 25% of your account."

But 25% on one trade is suicidal in reality. Why? Because:

1. You don't know your actual W and R — you only estimate them from the past, and the future is different.
2. Full Kelly has brutal swings — −50% drawdowns are normal on the way to profit. Most people can't handle it psychologically and bail out at the worst point.

That's why pros use half-Kelly (half) or even less. Half-Kelly gives you ~75% growth with ~50% volatility. For a beginner, even half-Kelly is too much — that's why we return to the simple rule of 1–2% per trade, which is even more conservative and safer in practice. Kelly mainly serves as a mental brake: it reminds you that there is a ceiling above which betting is mathematically harmful, not heroic.

Ralph Vince (optimal f) went even further and showed that betting more than the mathematically optimal share not only doesn't make you richer faster, but actively destroys you — the growth curve falls steeply after exceeding the optimum. Bigger bet ≠ bigger profit. Beyond a certain point, it's pure risk without reward.

Part 3: Stop Alert — How to Protect Capital

O'Neil's −7/−8% Rule

William O'Neil (founder of Investor's Business Daily, author of the CAN SLIM method) had one strict, simple rule: if a stock drops 7–8% below your purchase price, it's time to exit. No exceptions, no hope, no "it'll come back."

The logic: a good entry "catches on" quickly. If a stock falls right after purchase, your thesis was likely wrong or the timing was off. A small −8% loss is a cheap lesson. If you let it grow to −30% or −50%, you'll find yourself in the mathematical trap from the first table.

ATR-Based Stops — Stop According to Stock Volatility

A fixed −8% is a great start, but not every stock moves the same. A calm dividend stock moves ±1% a day, a wild small-cap ±8%. Giving both the same stop doesn't make sense — the wild one will stop you out unnecessarily due to normal noise.

That's why a more advanced approach uses ATR (Average True Range) — the average daily range of a stock. The stop is placed, for example, 2–3× ATR below the entry. This way, the stop respects the nature of the specific stock: tight for calm, looser for volatile. You avoid "getting shaken out by noise," but still have protection against a real drop.

★ Insight: A stop isn't a sign of weakness, it's a sign of discipline. Beginners hate stops because "they sell at a loss." But a stop doesn't protect your ego — it protects your capital, so you can play the next trade. The most expensive sentence in trading is: "It'll come back." Sometimes it does. And sometimes it drops 80% and never comes back.

Important for QMA: "Stop alert" means an alert, NOT an automatic sale. QMA will send you a signal when the price drops to your stop level. It won't sell for you — you manage the exit yourself. It's an alarm clock, not an autopilot. This freedom is intentional: the decision remains yours, but you'll be informed in time.

Part 4: Asymmetry of Risk/Reward (R:R)

This is perhaps the most important concept of the whole part. Risk/reward (risk to reward ratio, R:R) says: how much do I risk versus how much can I gain.

• Stop −10%, target +20% → R:R = 1:2 (risk 1 to gain 2)
• Stop −10%, target +30% → R:R = 1:3

Pros look for trades with R:R of at least 1:2, ideally better. Why is it so powerful? Because good asymmetry allows you to profit even with a win rate below 50%.

Let's calculate it. Let's say you risk 1 unit per trade and your ratio is 1:3 (win → +3, lose → −1):

Win Rate	Out of 10 Trades	Result
40%	4 wins (+12) − 6 losses (−6)	+6 units ✅
30%	3 wins (+9) − 7 losses (−7)	+2 units ✅
25%	2.5 wins (+7.5) − 7.5 losses (−7.5)	0 (break-even)

Do you see it? With R:R 1:3, you profit even if you're right in only 3 out of 10 trades. That's a liberating realization. You don't have to be almost always right — you just have to ensure your wins are significantly larger than your losses.

★ Insight: "Be sure" is a trap. "Have good asymmetry" is the solution. A beginner chases certainty (high win rate) and still loses because they let wins be small and losses big. A pro tolerates frequent small losses because they know a few big wins will pay for everything. Let profits run, cut losses short — that's the whole game in one sentence.

Part 5: Diversification vs. Concentration

How many stocks to hold at once? Two geniuses, two opposite opinions:

• Warren Buffett: "Diversification is protection against ignorance. For those who know what they're doing, it makes little sense." Buffett concentrates on a few best ideas.
• Ray Dalio: diversification is the "holy grail of investing" — 15–20 uncorrelated bets dramatically reduce risk, without reducing expected return.

Who's right? Both — it depends on who you are. Buffett has decades of experience and deep insight into several companies. A beginner doesn't have that insight, so for them, Dalio is a safer advisor.

Practical rule for starting: hold 8–15 positions, none more than ~10–15% of the account, and watch correlation — five tech stocks aren't five bets, it's one bet in five disguises. If the sector falls, your entire "diversified" portfolio falls at once.

QMA helps you with this specifically: Portfolio Health shows concentration and correlation of positions. If you have too many similar stocks, it alerts you that your "diversification" is an illusion.

Part 6: Complete Decision Tree (Summary of the Entire Series)

Now let's put it together. Here's a 10-step checklist — the entire series in one repeatable process. You'll go through this every time before opening a trade. Next to each step is the series part number and the place in QMA where you do it.

1. STYLE (step 2) — Do I know what type I am? Investor (months–years), swing trader (days–weeks), or day trader? → This determines everything else.

2. STRATEGY (step 3) — Do I have a specific, proven strategy with rules? Multibagger, momentum, dividends, value? → Strategy

3. MARKET PHASE + CYCLE + SEASONALITY (step 4) — Is the market in a bull or bear phase? What is the macro regime? Does seasonality fit? → Dashboard + Radar

4. SENTIMENT / FEAR (step 5) — What is the crowd doing? Extreme greed (caution), or extreme fear (opportunity)? → Fear & Greed on Dashboard

5. STOCK SELECTION (step 6) — Do the 5 pillars fit (value, momentum, smart money, sentiment, catalyst)? Is there a smart money confluence? → Screener → stock detail (verify)

6. POSITION SIZE + STOP + TARGET (step 7 — this part) — Have I calculated the size for 1–2% risk? Do I have a stop level and target price? Is R:R at least 1:2? → Simulator + Portfolio Health

7. ENTRY — Am I entering according to strategy rules, not emotion? Is it not too late, am I not chasing a runaway train?

8. POSITION MANAGEMENT — Am I moving the stop up when it runs (trailing)? Am I not taking profit too early out of fear? → Portfolio + Guardian

9. EXIT — Am I exiting at the target, at the stop, or when the thesis breaks down? Planned, not panicked. → Stop alert (alerts, doesn't sell)

10. JOURNAL + EVALUATION — Have I recorded the reason for entry? Did the score at entry match? What will I learn for next time? → Trading Journal

★ Insight: This isn't a checklist you go through once. It's a loop. Step 10 (journal) sends you back to step 1 as a better trader. Every trade you honestly record and evaluate moves you forward. Traders who keep a journal improve. Those who don't repeat the same mistakes for years.

Part 7: How QMA Research Assistant Guides You Through It

The whole decision tree looks like a lot of work — and it is. That's why there's the QMA Research Assistant. It's not a fortune teller or a "give me a tip" button. It's a companion that knows your context — your watchlist, your portfolio, the current market state — and guides you through the tree in a natural conversation.

What it looks like in practice. Instead of clicking through five pages, you simply ask humanly:

• "What phase is the market in now and does seasonality fit?" → the advisor summarizes the macro regime and seasonal context (steps 3–4).
• "Do I have any stocks in my watchlist with strong pillar confluence?" → it goes through your list and describes where signals converge (step 5).
• "What position size would correspond to 1% risk on my account if the stop were at −8%?" → it calculates the size with you (step 6).
• "What does the risk and correlation of my portfolio look like?" → it directs you to Portfolio Health and describes the concentration (part 5).

The advisor always describes the situation and suggests the next step — it never tells you "buy this" or "sell that." The decision remains yours. That's intentional: the advisor is an analyst and coach, not a broker.

QMA Workflow — Five Stops, Over and Over

The entire platform is built to mirror the decision tree:

Stop	What You Do There	Tree Steps
Dashboard / Radar	Load context — market phase, sentiment, seasonality	3–4
Screener / Strategy	Find candidates by strategy and pillars	2, 5
Stock Detail	Verify individual stock in depth	5
Simulator / Portfolio Health	Calculate size, stop, target, correlation	6
Portfolio / Journal	Monitor position and evaluate	8, 10

Context → find → verify → size → monitor. Over and over. This is the rhythm of a disciplined trader, and QMA just materializes it on the screen.

Part 8: Common Mistakes (and How to Avoid Them)

Finally, a few traps that almost every beginner falls into. Knowing them in advance is half the defense.

1. No stop / moving stop down. The stock drops, you "temporarily" move the stop, "it'll come back." → Set your stop BEFORE entry and stick to it. Stop alert in QMA will notify you — the rest is up to your discipline.

1. Too large a position. You bet 30% of your account on one "sure" idea. → Stick to 1–2% risk per trade. No position should be more than ~10–15% of the account.

1. Chasing a runaway train (FOMO). The stock has already shot up +40%, you jump in at the top out of fear of "missing out." → Return to step 5 — do the pillars fit NOW, or are you chasing the crowd?

1. Cutting profit too early, holding loss too long. The exact opposite of what you want. → Let profits run (trailing stop), cut losses short (−8%).

1. Jumping between strategies. One didn't work → you immediately try another → none gets a chance to prove itself. → Stick to one proven strategy long enough for statistics to speak.

1. No journal. Without records, you don't know what works and what doesn't, so you repeat mistakes blindly. → Trading Journal — record the reason for entry and later verify if the score at entry matched the actual development.

★ Insight: Almost all these mistakes have one common root — emotions override the system. The decision tree and strict risk rules aren't bureaucracy. They are guardrails that protect you from yourself when the market is wild and your brain screams "buy!" or "sell!". The system is cold when you can't be.

Conclusion of the Series: Defense Keeps You in the Game, Time Enriches You

We've gone through seven steps together. From understanding what type of trader you are, through strategy, market phases, sentiment, and stock selection, to here — the most important: how not to destroy your account and stay in the game.

Remember one thing from the entire series: survival is a strategy. Picking a great stock can enrich you once. Disciplined risk management keeps you alive for decades — and over decades, with reasonable asymmetry and small controlled losses, a small capital becomes large. The market rewards the patient and disciplined. It punishes the reckless and impatient.

And you're not alone. Whenever you're unsure of the next step, ask the QMA Research Assistant — it knows your context and guides you through the tree. Return to the beginning of the series whenever you want to refresh the basics, or to Step 6 when selecting a specific stock.

Good luck. And most importantly — survive first.
