Independent market analysis
Long-form research on portfolio construction, risk, macro and the tools that actually move returns. No hype, no tips, no paywall.
Real yields explained about a quarter of gold's monthly moves in 2003–2021 and about a sixth since, and the link has barely weakened. Yet the same relationship, applied to 2022–2026, implies a 13% fall in gold; it rose 136%. Gold also cushioned only two of the last four equity bear markets.
Over the 20 years to June 2026, 92.6% of US large-cap active funds trailed the S&P 500 after fees, and only about 51 of 690 both survived and beat it. The harder problem is picking them in advance: five-year persistence among winners was no better than chance.
The 10-year Treasury closed at 5.01% on 16 and 18 September 2026, the highest since July 2007, after the Fed's first hike in more than three years. Since 1 May the whole rise has been in real yields: breakeven inflation fell from 2.48% to 2.33%, while consumers now expect 4.6% inflation next year.
The S&P 500 has had eleven bear markets since 1950. The median one took 24.5 months to regain its previous peak in price terms — but price ignores dividends and inflation. Count both, and the 2000 peak was not recovered until May 2013: one drawdown of nearly thirteen years, not two separate crashes.
Six biases measured on real accounts: trading frequency cost the most active US households 7.1 points a year, the disposition effect 3.4, switching holdings 3.2, and fund timing 1.2. The numbers are real, they come from different samples and decades, and adding them together — as most articles do — produces nonsense.
Backtrader tops almost every 2026 ranking of Python backtesting libraries. Its last commit was in April 2023. Here is what the registries say about all six, and the licence question nobody mentions.
The Kelly criterion says bet 10% per trade on a 55/45 edge — the growth-optimal fraction. Simulated over 200 trades, that same fraction produces a 50% peak-to-trough drawdown in 93% of runs, and ends below half the starting capital once in ten. Half Kelly keeps three-quarters of the growth and a fraction of the pain.
Run $10,000 plus $500 a month at 7% for 40 years and the calculator shows $1.48 million. Only 17% of that — $250,000 — is money you actually put in. The other 83% is growth compounding on growth, and by the final decade it does nearly all the work.
A hedge is insurance with a running premium, not a strategy. Rolling put protection on the S&P 500 has compounded at 6.64% a year since 1986, while simply holding 65% equities and 35% Treasury bills beat it by 0.6% a year with lower risk. What each instrument actually costs.
Rebalance about once a year, and only past a five-point drift. Rebalancing keeps risk at target; it does not reliably add return. What the research finds, what drift costs in drawdown, and how to do it without realising a gain.
