09 · Markets and Instruments

The previous eight chapters run vertically by "asset class": spot, stocks, futures, crypto contracts, technical analysis, trading systems, and pitfall survival.

This chapter switches dimension — filling in "instruments and markets" horizontally: forex, bonds, funds, and options. These four markets differ from the earlier focus (stocks/futures/crypto): they are larger, more mechanically complex, and their entry barriers vary enormously. Forex is the largest financial arena in the world, bonds are the "master switch" of interest rates, funds are the most accessible asset tool for ordinary people, and options are the most sophisticated "financial instrument". Only by understanding them do you understand the skeleton of the entire financial world.

Cross-chapter ownership: This chapter owns the horizontal market map and the mechanism deep dives for non-stock instruments. Stock rules and analysis belong in 04 · Stocks↗, futures margin and contract mechanics in 03 · Futures↗, and crypto spot/contract foundations in 01 · Spot↗ and 05 · Crypto Perpetuals↗. This chapter repeats only the minimum background needed for comparison, not full rule tables maintained elsewhere.

⚠️ Risk Warning

This chapter is for learning and research only and does not constitute investment advice. The instruments, fee rates, leverage ratios, index compositions, and other details mentioned here are generic descriptions for teaching purposes. Always defer to the latest rules and quotes from each exchange/platform. Forex margin trading and options are high-risk derivatives — assess your own risk tolerance before participating.

Article Guide

01 · Forex Market

The forex market turns over more than USD 6 trillion daily (2022 BIS survey basis), making it the true "king of markets" beyond stocks and bonds. This article explains its rules of the game: who the main players are (banks/central banks/hedge funds), how to read a quote (base currency/quote currency), how a pip is calculated (with numeric examples), the basket composition of the US Dollar Index DXY, and the "high leverage" traps and rogue-platform risks unique to retail forex.

02 · Bonds and Interest Rates

Bonds are the "price list of money" — the valuation of every asset in the world rests on the risk-free rate. This article explains the inverse relationship between price and yield, why an inverted yield curve is read as a recession signal, why the US 10-year Treasury is the pricing anchor of global assets (when it moves, gold/stocks/crypto all follow), and the bond plays ordinary domestic investors can actually access: government bonds, bond funds, convertible bonds, and reverse repo.

03 · Funds and ETFs

For most people the most convenient market tool is not a stock but a fund. This article clarifies the core concept pairs — public/private, active/passive, off-exchange/on-exchange — breaks down the arbitrage mechanism between ETF primary-market creation/redemption and secondary-market trading, uses the argument "S&P 500 long-term annualized ~10% vs most active funds underperforming the index" to explain the logic of index investing, and covers the principle of dollar-cost averaging, a broad-based index list, and common ETF reference tickers.

04 · Options Basics

Options are "buying a future right at limited cost" — and also the derivative where it is easiest to lose money. This article covers Call/Put, the four elements, a buyer-vs-seller rights and obligations comparison table, IV and the Greeks (Delta/Theta/Vega, etc.), the use cases of common strategies such as covered calls, protective puts, straddles, and spreads, and finally the options retail investors in China can actually access: SSE 50 ETF options, CSI 300 ETF options, and commodity options.

09 · Precious Metals and Energy Spot

There are ten thousand ways to "buy gold": bars, paper gold, gold ETFs, gold T+D, London gold — with wildly different thresholds and leverage. This article lays out a comparison table of the five main forms of spot gold, explains the high volatility brought by silver's industrial character, why crude oil has no true "spot" market (storage/transport/quality standards), and highlights a checklist for identifying domestic "spot oil/spot silver" bucket shops. It closes with the London gold/Shanghai gold/WTI/Brent pricing anchors, common ranges for the gold-silver and oil-gold ratios, and a table of participation paths chosen by purpose.

10 · HK and US IPO Subscription

The era of "guaranteed profit on allotment" in A-shares is over; under the registration system and in HK/US markets, breaking issue price is the norm. This article compares the IPO issuance and allocation mechanisms of A-shares/HK/US stocks, breaks down the full HK IPO subscription process (offering timeline, grey market, margin financing, the one-lot-per-person strategy), explains why retail investors get no allocation in US IPOs, and covers SPACs, first-day behavior and the greenshoe mechanism, shadow stocks, and newly-listed stock games.

11 · REITs and Real Estate Investing

"Buying a home" is the deepest asset obsession for most people, but the house itself is not the asset — the house that produces rental cash flow is. This article compares the four ways to invest in real estate (buying property directly/REITs/real estate funds/property stocks), explains the mechanics of REITs (securitization of real property, mandatory 90% distribution of income), the landing of domestic public REITs (first batch listed in 2021, asset types such as industrial parks/expressways/warehouses/public housing, the 30% first-day/10% daily price limits versus new-share rules, forced distribution), and covers overseas REITs (US/Singapore/HK), the impact of Fed rate hikes, and a full REITs-vs-direct-purchase comparison table, closing with an objective framework for "should you still buy property" (rent-to-price ratio/demographics/policy) and key REIT investing points.

12 · Alternative Assets

Moutai, Rolex, whisky casks, designer toys, and digital collectibles — "monetize your hobby" is one of the most seductive narratives, but for the vast majority of hobby investments, the primary attribute is consumption and only the secondary one is investment. This article lays out the full landscape of alternative assets and dissects the five fatal flaws of "hobby investing": the liquidity trap (easy to buy, hard to sell), channel spreads (buyback prices often sit 20%-40% below market), authentication and counterfeit risk, storage costs (temperature/humidity/insurance/upkeep), and the lack of a pricing benchmark. It fact-checks popular narratives like "Moutai/Rolex/gold", and gives position discipline (no more than 5%-10%, treat it as entertainment) and a practical checklist for "if you really must play".

13 · Volatility and VIX

The second dimension beyond price is volatility. This article explains the difference between historical volatility (HV) and implied volatility (IV) and how to annualize them, breaks down how the VIX "fear index" is constructed (weighted implied volatility of S&P 500 options), its mean reversion and spike character (typically 12-20 in calm times, 40-80+ in crises), its negative correlation with stocks, and VIX futures contango and its drag on products like VXX. It compares crypto-market volatility common sense (BTC annualized volatility is roughly 3-5x US stocks) and explains what volatility means for traders (low volatility → prelude to a regime change) plus entry-level volatility trading tools and when to use them.

14 · Commodity Indexes and Cycles

Commodity markets are driven by three stacked rhythms: the supercycle, the macro cycle, and the inventory cycle. This article compares how the CRB / S&P GSCI / Nanhai commodity indexes are constructed and what they represent, shows that commodity prices are a leading indicator of CPI, dissects two supercycles (2000-2014 China-demand driven, 2020-2022 pandemic supply shock) and how to recognize them, maps the macro linkages between commodities and the dollar index, manufacturing PMI, and geopolitics, and covers the role of commodities in asset allocation (inflation hedge/low correlation/gold's special status). It closes with participation routes for ordinary investors and three common mistakes (holding commodities like stocks, ignoring roll costs, watching price but not inventories).

15 · DeFi and On-Chain Deep Dive

A hands-on deep dive building on the DeFi introduction in chapter 07. The article first gives the DeFi panorama (disintermediated, code is law) and one-line positioning of six protocol categories (DEX/lending/derivatives/stablecoins/yield aggregators/liquid staking), then breaks down the four main plays: Ethereum staking (32 ETH node vs liquid staking stETH), lending (collateral ratio/liquidation line with numeric examples: borrow 70% of collateral value, a 20% price drop triggers liquidation), liquidity mining (impermanent loss numeric example: when pooled assets double, IL is about 5.7%; the trap of headline APR), and yield aggregation (auto-compounding and stacked risk). Next come cross-chain bridge principles and the 2022 Wormhole/Ronin/Nomad exploits, the full DeFi risk map (contract bugs/depegging/oracle manipulation/rug pulls/admin keys), the expected-value math of "long-term annualized yield vs one blow-up to zero", and finally an entry route for ordinary participants (wallet security → small amounts in head protocols → only businesses you understand → check audit reports) and a trading angle on "on-chain rates as a market sentiment gauge".

Learning Order for This Chapter

① Forex market (first meet the world's largest market)
   ↓
② Bonds and interest rates (then understand "interest rates", the master switch)
   ↓
③ Funds and ETFs (an actionable tool for ordinary people)
   ↓
④ Options basics (the most complex tool, touched only last)

• Suggested order: reading 02 before 01 also works — the bonds part explains how interest rates transmit, and interest-rate differentials are the core driver of forex; the two are two sides of one coin.
• Article 04, options, is the hardest part of this chapter. Read the margin and forced-liquidation sections of chapter 03 - Futures↗ first, and options will go much more smoothly.
• The next chapter, 10 - System Integration↗, switches to the software-company perspective and covers system design and implementation for exchange connectivity.
