# Investment Strategy: Asset Classes, Factors, Costs, Tax Concepts, and Asset Allocation

> **Part 2 of 6** of the *Gold Standards for Investment Strategy* reference (plugin `investment-strategy-personal-and-business`), covering §6–§10. Sibling skills: `invest-foundations-risk-compounding-diversification-and-efficiency` (§0–§5), `invest-rebalancing-vehicles-accumulation-decumulation-and-behaviour` (§11–§15), `invest-business-capital-budgeting-cost-of-capital-and-valuation` (§16–§22), `invest-fraud-alternatives-and-advisor-conflicts` (§23–§25), `invest-reference` (§26–§31). Section numbers are shared across the set; a reference written as §N → `skill` points into that sibling skill.

> **Currency:** The core findings are decades old. Two areas are genuinely live. See §26 → `invest-reference` for the active-versus-passive evidence, and private markets entering retirement accounts.

> **⚠️ NOT FINANCIAL ADVICE, and this matters more here than the usual disclaimer.**

> **⚠️ Tax and regulatory specifics are JURISDICTION-DEPENDENT and change.** ⚠️ **Where I

> for anything consequential use a qualified professional.**
>
> **⚠️ GOTCHA** boxes mark where the evidence contradicts the marketing.
>
> **The three ideas that organize this document:**
> 1. **⚠️ COSTS are the only reliable input you control** (§8). **Returns are uncertain;
>    fees are certain. Over decades the arithmetic is brutal and it compounds against you.**
> 2. **⚠️ BEHAVIOUR dominates selection** (§15 → `invest-rebalancing-vehicles-accumulation-decumulation-and-behaviour`). **The gap between fund returns and
>    INVESTOR returns is real and well documented — most damage is self-inflicted through
>    buying high and selling low, not through picking the wrong fund.**
> 3. **⚠️ Diversification is the only thing in finance that is close to a free lunch**
>    (§4 → `invest-foundations-risk-compounding-diversification-and-efficiency`). **Everything else is a trade-off between risk, return and liquidity, and anyone
>    offering you all three should be assumed to be hiding one.**

## §6. Asset Classes

```
⚠️ EQUITIES  ownership. ⚠️ Highest long-run real return historically,
   with the largest drawdowns. ⚠️ Note SURVIVORSHIP BIAS in
   long-run return data — the most-cited series come from markets
   that DIDN'T collapse. Several 20th-century markets went to zero
⚠️ BONDS  lending. ⚠️ Return comes from yield, and ⚠️ price moves
   INVERSELY to rates. ⚠️ DURATION measures that sensitivity —
   long bonds are far more volatile than people expect, as 2022
   demonstrated. ⚠️ Credit risk and interest rate risk are distinct
⚠️ CASH  ⚠️ liquidity and optionality; ⚠️ negative real return
   when inflation exceeds the rate
⚠️ PROPERTY  ⚠️ leveraged, illiquid, concentrated, with real
   transaction and maintenance costs. ⚠️ Reported returns often
   ignore the costs and the labour
⚠️ COMMODITIES  ⚠️ no cash flow, so no intrinsic return —
   the return is price change plus roll yield. Inflation hedge
   properties are weaker than commonly claimed
⚠️ INFLATION-LINKED BONDS  ⚠️ the most direct inflation hedge
⚠️ PRIVATE ASSETS  see §24 and §26.2
```

## §7. Factors

**⚠️ Empirically identified sources of return beyond market exposure**: ⚠️ **size, value,
momentum, profitability/quality, and low volatility are the commonly cited ones.**
**⚠️ The honest position, which sits between the marketing and the dismissal:**
⚠️ **the historical evidence is real and was found in large datasets across markets.**
⚠️ **But: many factors have weakened after publication (consistent with either
arbitrage or with the original result being partly data-mined); the replication crisis
touched finance hard, with a large fraction of published anomalies failing to survive
scrutiny; and factor premia can underperform for periods LONGER THAN MOST INVESTORS'
PATIENCE — a decade or more.**
> **⚠️ GOTCHA — the practical problem with factor investing is not whether the factors are
> real. It is that capturing them requires holding an underperforming strategy for a
> decade without abandoning it** (§15 → `invest-rebalancing-vehicles-accumulation-decumulation-and-behaviour`), **and paying higher fees to do so** (§8).
> **⚠️ Most investors who tilt end up selling the tilt at the bottom, which converts a
> theoretical premium into a realized loss.**

## §8. ⚠️ Costs

> **⚠️ The one input you control with certainty, and the arithmetic is unforgiving.**
```
⚠️ THE CATEGORIES
   Expense ratio / OCF · ⚠️ ADVISORY FEE (often the largest single
   cost) · trading costs and spreads · ⚠️ BID-ASK on illiquid
   assets · platform and custody fees · performance fees ·
   ⚠️ TAX DRAG from unnecessary turnover (§9)
⚠️ THE ARITHMETIC  ⚠️ a 1% annual fee over several decades removes
   a substantial fraction of the terminal outcome — far more than
   "1%" suggests, because it compounds against you every year
⚠️ SHARPE'S ARITHMETIC OF ACTIVE MANAGEMENT  ⚠️ before costs, the
   average actively managed dollar must earn the market return,
   because active investors collectively ARE the market.
   ⚠️ Therefore AFTER costs the average active dollar must
   UNDERPERFORM. ⚠️ This is arithmetic, not an empirical claim,
   and it holds regardless of manager skill
⚠️ PERFORMANCE FEES  ⚠️ asymmetric — the manager shares the upside
   and not the downside. ⚠️ Check for high-water marks and hurdles
```
**⚠️ Where paying more can be justified**: ⚠️ **genuine planning and behavioural coaching
(§15 → `invest-rebalancing-vehicles-accumulation-decumulation-and-behaviour`, §25 → `invest-fraud-alternatives-and-advisor-conflicts`), tax and estate complexity, and access to markets you cannot reach otherwise.**
**⚠️ Where it usually isn't: paying for stock selection** (§26.1 → `invest-reference`).

---

## §9. Tax Concepts

> **⚠️ Jurisdiction-specific. These are the CONCEPTS to ask your own advisor about, not
> your rules.**
**⚠️ Account type matters**: ⚠️ **tax-deferred, tax-exempt and taxable accounts have
different arithmetic, and the choice between "pay tax now" and "pay tax later" depends on
rate expectations you cannot know.**
**⚠️ ASSET LOCATION** (as distinct from allocation): ⚠️ **placing tax-inefficient assets in
sheltered accounts and tax-efficient ones in taxable accounts.**
**⚠️ Turnover creates tax events** — ⚠️ **which is one reason low-turnover strategies have a
real advantage in taxable accounts beyond their lower fees.**
**⚠️ Tax-loss harvesting** is real and constrained by wash-sale-type rules.
> **⚠️ GOTCHA — do not let the tax tail wag the investment dog.** ⚠️ **Refusing to sell a
> dangerously concentrated position because of the tax bill has destroyed more wealth than
> the tax would have** (§4 → `invest-foundations-risk-compounding-diversification-and-efficiency`). **⚠️ And any structure whose primary purpose is tax avoidance
> rather than a real economic purpose deserves scrutiny** (§23 → `invest-fraud-alternatives-and-advisor-conflicts`).

# PART II — CONSTRUCTION AND BEHAVIOUR

## §10. Asset Allocation

**⚠️ The allocation decision explains the large majority of a portfolio's return
VARIABILITY over time** — ⚠️ **which is the actual finding, frequently misquoted as
explaining most of the return LEVEL.**
```
⚠️ THE INPUTS
   ⚠️ HORIZON — when is the money needed, and in what pattern?
   ⚠️ RISK CAPACITY (⚠️ objective — can you afford the loss?)
      vs RISK TOLERANCE (⚠️ subjective — will you SELL in a crash?)
      ⚠️ The binding constraint is whichever is LOWER
   ⚠️ Liabilities and obligations · income stability (§4's human
      capital) · tax position · other assets
⚠️ COMMON HEURISTICS, and their limits
   ⚠️ "Age in bonds" and similar rules ignore everything specific
      about you. Useful as a starting anchor, not an answer
   ⚠️ GLIDE PATHS (target-date funds) automate the shift and are a
      reasonable default for people who won't otherwise decide
⚠️ THE TEST THAT MATTERS  ⚠️ what would you do if this portfolio
   fell 40%? ⚠️ If the honest answer is "sell," the allocation is
   wrong regardless of what the optimizer says
```
**⚠️ On mean-variance optimization**: ⚠️ **it is elegant and extremely sensitive to inputs
you cannot estimate reliably — small changes in expected return assumptions produce wildly
different portfolios.** **⚠️ Treat optimizer output with suspicion.**
