Welcome to the Deep Dive!

Here each week on ‘The Deep Dive’ we take a close look at cutting-edge topics on algo trading and quant research.

This Week, we deep dive into how to create passive portfolios that maximize returns, minimize risk & minimize taxes. All the materials presented are from live trading and portfolio management.

Bonus Content, we dive even deeper into portfolio management with a practical guide to illustrate how professionals improve portfolio outcomes.

All materials are for informational purposes only and do not constitute investment advice. Figures are illustrative and intended to demonstrate structural effects rather than forecast performance.

Feature Article: How to Optimize Passive Portfolios to Maximize Returns, Minimize Risk & Taxes

Passive portfolios succeed when they are designed to survive time. Markets do not move in straight lines, and even strong long-term trends experience drawdowns of 10–20% or more. A professionally engineered passive portfolio therefore builds in wiggle room: sufficient diversification, liquidity, and downside controls to allow positions to recover and generate attractive returns without forcing sales at precisely the wrong moment. The objective is not to avoid volatility — is neither realistic nor desirable as excessive trading only increases transaction costs — but to ensure volatility does not translate into permanent capital loss or unnecessary tax realisation.

Tax Efficiency - Asset Allocation & Exchange Traded Funds (ETFs)
Tax is where outcomes diverge dramatically. For high earners and high-net-worth investors, marginal tax rates on income and realised gains can easily reach 40–50%. At those levels, a seemingly attractive 10% gross return quietly degrades into 5–6% after tax — before inflation. Over multi-year horizons, this dominates performance. This is why professional passive portfolios are often built primarily using accumulating ETFs, where income is unrealized, reinvested internally and hence taxation is deferred. Both asset allocation and the choice of instrument determine whether returns quietly grow in the background or leak away to taxes every year.

Sovereign Bonds, Options & Tail Risk Controls
Combined with high-quality sovereign bond exposure and explicit tail-risk controls — such as small allocations to long, out-of-the-money index puts — a portfolio gains robustness without sacrificing upside participation.

Commodities - Diversification, Drawdown Resilience & Inflation Hedging
Commodities play an important supporting role. Gold, in particular, has achieved phenomenal gains over the last year, with 2025 returns exceeding 25%, while silver also recorded impressive gains around 35%, making both metals some of the strongest-performing asset classes. A modest allocation — typically 5–10% of a portfolio — provides diversification, drawdown resilience, and a partial hedge against inflation and monetary instability. In a professionally constructed portfolio, precious metals are not speculative; they are structural stabilisers.

Dollar Cost Averaging (DCA) & Selling Puts to Buy on Market Lows
Finally, DCA systematically spreads purchases over time, reducing the risk of mistimed entries, while selling cash-covered puts allows you to get paid to buy assets at lower levels during market dips, effectively combining disciplined investing with execution.

Bonus Article: An Illustration of How Professionals Improve Portfolio Outcomes

Financial Markets & Headline Returns
Headline market performance often looks impressive until tax and implementation are applied. Recently, broad equity markets delivered high single to low double-digit returns, while commodities such as gold returned over 25% and silver 35% in 2025. On paper, a diversified passive portfolio might show returns in the 8–12% range.

An Illustration: How much money can we make?
For a USD 1,000,000 portfolio, that equates to roughly USD 80,000–120,000 per year (approx. USD 6,500–10,000 per month). After tax, inefficient implementation can easily reduce this to USD 45,000–65,000 (approx. USD 4,000–5,500 per month). Structured correctly — using accumulating ETFs, tax-aware instruments, and controlled income overlays — a significantly larger share of returns remains unrealised and compounding.

Professional Trading & Execution
Professional portfolios also improve entry and income without abandoning a passive framework. Rather than deploying capital all at once, market entries can be managed using cash-covered put selling, allowing the portfolio to earn income while waiting to acquire assets at more attractive levels. Once positions are established, selective covered call selling can further monetise volatility or reduce cost basis — an approach often referred to as the wheel strategy. During higher-volatility regimes, drawdowns can be actively managed using collar structures, where upside is partially monetised to fund explicit downside protection. These tools are not speculative overlays, but mechanical methods for smoothing returns and controlling risk over the medium term.

Live Trading & Portfolio Management
All concepts discussed across these newsletters are grounded in real-world implementation. The mathematics, programming, pricing models, and risk analytics are not theoretical exercises — they are operational systems used to manage live portfolios across electronic markets.
