Survive First, Profit Later: Building a "No-Crash" Investment Discipline and Portfolio System

Speaker: Jeremy Tan, Investment Representative at Tiger Brokers (Singapore) $Tiger Brokers(TIGR)$ , as he shares how these concepts relate to modern market mechanics, including position sizing, catalysts and options. He will also bring you through the Barbell portfolio approach in global and Singaporean markets, alongside analytical frameworks used to assess global equities and the broader SEA small-cap market.

[About the Speaker]

Jeremy Tan is a CFA charterholder with over 25 years of hands-on experience in equities, futures trading, property development, and business growth. Having managed portfolios through multiple market cycles — from the Asian Financial Crisis to today's AI boom — he has a proven track record in both rising and declining markets. A sought-after speaker at SGX derivatives workshops in Singapore and Taiwan, Jeremy is fluent in English, Mandarin, Hokkien, and Cantonese, and brings deep expertise in Southeast Asian markets, value investing, and tactical trading.

[The Hook] "A 27-year-old fund manager turned $50 million into $42 billion in six months — then lost so much he almost couldn't afford to get married."

Jeremy was referring to a recent Wall Street blow-up. "Too much leverage, no stop-loss, and a wedding on Saturday. The biggest risk in investing isn't the market — it's you."

This from a man who learned his discipline on the trading floor during the Asian Financial Crisis, wearing a red jacket and shouting out futures orders in what looked like a fish market. He knows what it means to survive.

[Discipline 1: Stop-Loss Is Your Lifeline]

Jeremy's hard rule: Cut at –8%. "I reviewed every bad trade I've ever made. If I'd followed this rule, I'd have saved a fortune."

This isn't a technical problem; it's a psychological one. "Admitting you're wrong is hard. Letting a mistake become a disaster is harder."

[Discipline 2: Position Sizing — The Kelly Criterion]

Legendary mathematician Ed Thorp (who beat blackjack and then the market) proved through the Kelly Criterion: No matter how much you love a stock, never risk more than 1–2% of your capital on a single bet. "Don't fall in love. The market will always offer another opportunity; your capital won't."

[Portfolio Construction: Core-Satellite]

If you don't have time to research, or if you admit that "stock picking is hard," Jeremy recommends a "lazy but robust" framework:

Allocation

Asset Type

Role

Examples

~30%

Dividend stocks + bonds

Cash-flow "mattress"

DBS, UOB, CCB, T-bills, REITs

Remaining 70%

Sector ETFs + core individual stocks

Growth engine

Nasdaq ETF, Biotech ETF, high-conviction names

"Why ETFs? AI will accelerate biotech drug discovery, but we're not scientists. We can't parse clinical trials. So buy a biotech ETF holding 30 names — bet on the track, not the horse."

[Discipline 3: Circle of Competence — If You Don't Understand, Don't Touch]

"Duan Yongping said it. Buffett said it. It sounds like common sense? Less than 1% of investors actually do it."

Jeremy confesses he missed NVIDIA: "My friends told me at 30x PE. I thought it was too expensive. It's a great business, but outside my valuation comfort zone — that's fine. Admitting 'I don't know' is safer than pretending you do."

[Modern Tools: Let AI Be Your Analyst]

Here's a practical tip from Jeremy, who now builds AI investment systems: Use AI to read earnings reports. "When a quarterly report drops, copy-paste it into an AI agent and ask: 'What is management really saying? How's the cash flow? What are the risks?' What used to require a team now takes one person five minutes."

He runs two AI agents — one fundamental, one technical — scanning global markets 24/7. "The future of investing isn't who works hardest; it's who asks the best questions."

[Global Allocation: Fish Where the Fish Are]

"Singapore is a small pond. China, Southeast Asia, and the US are the oceans."

Jeremy's geographic framework:

  • China (Shenzhen, Shanghai, HK): "They're simply returning to where they were a thousand years ago. Go to Shenzhen — drones delivering coffee, kids playing with robots like dolls. You're looking at the future."

  • Southeast Asia: "When Indonesians and Thais get rich, where do they park their money? DBS. That's our home-ground advantage."

  • US: "Best liquidity, but valuations are stretched. Wait for dips."

[Key Takeaways]

  • Margin of Safety: Applies not just to stock picking, but to portfolio construction. Always leave room for error.

  • Rebalancing: Trim what has run up; add to what has dropped. Let rules replace emotions.

  • Long-termism: "In the short run, the market is a voting machine. In the long run, it's a weighing machine." Buy great businesses, and let time do the heavy lifting.

[Call to Action 🎯]

Spend 10 minutes tonight on an "Investment Health Check":

  1. Check your stop-losses: What's your worst performer? How far down is it? If you haven't set a stop, set one now.

  2. Check your "sleep-at-night" ratio: Do your income-generating core holdings make up at least 20–30% of your portfolio?

  3. Check your circle of competence: How many of your holdings can you explain in one sentence — what they do and how they make money? For any you can't, consider trimming.

  4. Drop a comment: What's the "anchor" in your portfolio that lets you sleep soundly?

[Series Conclusion]

These three articles, drawn from Jeremy Tan's 25+ years of investing across crises and booms, form a complete map:

What to buy (philosophy), How to find it (execution), and How to survive (risk management).

As Jeremy put it: "This game is hard. If it were easy, everyone would do it. That's exactly why the disciplined few earn the excess returns."

Publishing cadence suggestion: One article per week, paired with community discussion, to create sustained investor education and engagement.

    我最认同这一篇里的核心不是“8%止损”或者“买ETF”,而是 先活下来,再谈长期复利。

    如果说前面讲的是“买什么”,这一篇真正讲的是 仓位、纪律和能力圈。很多投资者的问题其实不是看错一次,而是看错以后不断加仓、没有止损、单一仓位过重,最后把一次普通判断错误变成组合级别的伤害。

    不过我不会机械套用“任何股票跌8%就卖”。对波动很大的科技股、半导体股来说,8%有时只是正常波动。更合理的是先确定 每笔交易最多亏组合的多少比例,再根据股票波动决定仓位和止损距离。真正重要的是风险预算,而不是死记一个百分比。

    “核心+卫星”这个框架我也很喜欢。核心仓负责让自己睡得着,卫星仓才去博AI、半导体、生物科技这类高弹性机会。这样即使某个主题判断错了,也不会影响整个组合。

    如果问我组合里的“锚”,我会选 宽基指数ETF。它不一定每年涨得最快,但可以避免把长期财富完全押在单一公司、单一故事上。

    一句话:投资真正的第一目标不是赚最多,而是避免一次错误把自己踢出牌桌;仓位管理,往往比选对股票更重要。

    Jeremy Tan’s biggest lesson isn’t about finding the next NVIDIA—it’s about surviving long enough to capture the next opportunity.

    The –8% stop-loss rule, disciplined position sizing, and staying within your circle of competence are simple ideas, but extremely difficult to follow when emotions take over.

    I especially like the “core-satellite” approach: build a stable foundation with dividend stocks, bonds or ETFs, then use a smaller portion for high-conviction growth opportunities.

    The smartest investor isn’t the one who predicts every winner. It’s the one who protects capital, controls risk, and stays in the game long enough for compounding to work.
