A three-minute overview

Confessions of a Speculator is André Kostolany's account, drawn from decades spent inside European markets. The book was written in German and reached Chinese readers as 《一个投机者的告白》; there is no single canonical English edition, so the title used here is a literal rendering rather than an official one. Kostolany never presents speculation as a science you can copy step by step. He treats it as the act of forming an independent judgment — and living with the consequences — while the data are incomplete and the future is unknowable. The recording that plays by default on this page is a merged complete edition covering the original seven parts, and it is narrated in Mandarin Chinese. We also keep two secondary recordings: an unlisted older version of part 1, offered as an alternate reading, and a short overview-and-commentary clip. Neither of those is a later installment of the main edition, and the single merged link must never be reused to stand in for the missing older parts 2 through 7.

Five core ideas

1. Judgment always comes with uncertainty

Kostolany returns again and again to a plain fact: no market participant ever holds all the facts. A trading plan needs a view, and it equally needs the admission that the view can be wrong. Experience, in his telling, is not the ability to call every move; it is knowing which conditions would overturn your original judgment, and leaving yourself enough room to absorb the mistake when they arrive.

2. Money and psychology move prices together

The health of a company or an economy does not move in lockstep with the price of its securities. Over short horizons, prices also answer to liquidity, position pressure, expectations, and crowd mood. That is why markets can run too far in either optimism or pessimism — yet how long a deviation lasts cannot be known in advance, and simply leaning against the crowd is no guarantee of profit.

3. Independent thinking beats following slogans

When most people merely extrapolate the current trend, it is worth re-examining the assumptions underneath the consensus. But being independent is not the same as reflexively contradicting everyone. The more reliable habit is to write down plainly what is fact, what is inference, and what is imagination, weigh the potential gain against the loss and the cost of waiting, and only then decide whether the risk is worth taking.

4. Patience needs conditions for survival

Before value has a chance to show itself, an investor first has to still be in the market. Too much leverage, short-dated debt, and concentrated bets can turn ordinary price swings into a forced exit, robbing a judgment that could have waited of the time it needed. Patience, then, is not only a temperament; it is the product of how you arrange capital and where you draw your risk limits.

5. Mistakes are experience, not a formula

The book's aphorisms, anecdotes, and market metaphors make human nature easier to grasp, but they are not laws tested against any consistent sample. A single success may owe something to luck, and a single loss does not prove the whole thesis was wrong. What matters is reviewing the reasoning behind a decision, the size of the exposure, and the reason for the exit — not labeling yourself afterward by nothing more than the final profit or loss.

Our editorial synthesis: guardrails for experience-based judgment

This section is our own generalization, not a program the book prescribes. We suggest turning these themes into a plain checklist. Use only capital that can withstand volatility over the long run. Before acting, write down the core assumptions, the conditions that would disprove them, and the maximum exposure you will accept. Separate a change in price from a change in the underlying facts. Do not add leverage because the crowd is euphoric, and do not let a short stretch of adversity harden an independent view into stubbornness. A framework like this cannot remove uncertainty, but it lowers the odds that a single mistake destroys your chance to keep making judgments at all.

Before you listen

Kostolany called himself a speculator, and he should not be rewritten into a pure, Buffett-style value investor. His recollections, maxims, and metaphors carry the strong stamp of a particular era and a personal career, and they cannot be extrapolated mechanically to every market. A Chinese book that shares this title, 《一个投机者的告白：实战版》 (a "practical edition"), is the work of a different author and does not belong on this page. Public videos can still be taken down or restricted by region, and the unlisted older upload in particular should not be treated as a stable long-term source. Past experience and personal technique are no forecast of future results.
