Position sizing is the quiet discipline most investors skip. Everyone wants the perfect entry, the macro call, the hot sector. But over a decade of managing private portfolios, what separates durable performance from a lucky stretch is rarely the idea — it's how much you put on, and what you do when it moves against you. Why position size matters more than the idea I've seen portfolios with excellent stock picks lose money because the best idea was 40% of the book and the second-best was 5%. The math is unforgiving: a 25% drawdown on the largest position requires a 33% recovery just to break even. That recovery rarely comes from the same name. It comes from the rest of the book — if you left room for it. In private banking, we're not managing a trading account. We're managing a standard of living, a legacy, a set of obligations that don't wait for markets to heal. That changes the conversation entirely. Liquidity is a feature, not a drag When volatility spikes, the investor with cash doesn't panic — they rebalance. The one who is fully invested is forced to sell what they can, not what they should. I keep a liquidity buffer in most client portfolios, not because I'm bearish, but because optionality is the only free lunch in markets. In the current macro context — with rate expectations shifting, earnings diverging, and geopolitical headlines creating intraday noise — that buffer is worth more than ever. It lets you be a buyer when others are forced sellers. Volatility is not risk — permanent loss is Too many investors confuse a 10% drawdown with risk. Real risk is the permanent impairment of capital: a business model broken, a balance sheet stretched, a thesis invalidated. Volatility is just the price of admission. The discipline is to separate the two in real time, without the noise of the day's headlines. Set a maximum position size before you buy, not after. Define what would make you wrong — in writing. Stress-test your portfolio against a 2008-style liquidity freeze, not just a 20% dip. Staying rational while markets move fast The hardest part of this job is not analysis — it's temperament. When a client calls after a 5% down day, the temptation is to do something. Often the best action is to review the allocation, confirm the thesis, and wait. I've learned to slow down the decision-making process precisely when the market speeds up. That's why I document every major allocation decision with a rationale and a revisit date. It keeps me honest, and it gives clients a clear framework to evaluate whether we're still on track. For affluent investors in Andorra and beyond, the goal is not to be the most aggressive or the most defensive. It's to be the most consistent — with a process that survives your own emotions and the market's mood swings. If you're reviewing your own portfolio's position sizing or liquidity buffer, a second pair of eyes can help. That's what I offer — not certainty, but a disciplined process.
