This quote is imputed to John Maynard Keynes (1883 - 1946). How do I translate it to Chinese?

My attempt with Google Translate: 股市保持非理性的時間, 要比保持破產的時間長。

Keynes was thus able to scrape together the money he needed to continue trading. He had learned a valuable but painful lesson – markets can act perversely in the short-term. Of this, he later famously commented:

“The market can stay irrational longer than you can stay solvent.”

The market can stay irrational longer than you can stay solvent.
股市保持非理性的時間, 要比保持破產的時間長。

The first part is okay (although there is no Chinese word meaning "can" or "able to"), but in the second part 保持破產 = "maintain bankruptcy" = "remain bankrupt" is the opposite of what the quote says. (Also, it might not be a Keynes quote.)

The grammar structure 比...长 is also not the closest possible match to the English, so I wouldn't use it (even though it's correct).

Anyway, let's see how it's translated online:

-- 凯恩斯
克纳普,理性的股票投资, 2013;Google Books (screenshot)

The last part above 长到令你破产 is something like "extends until you go bankrupt". I think 市场 = "market" is more general than 股市 = "stock market" (I believe shorthand for 股票市场); maybe 股市 is more precise.

财富, 2009; Google Books

Here 超过 = "exceed" and 清偿能力 = "solvency" are suitable. However, I feel the 可能 = "possibly" feels wrong (the quote does not say "possibly longer", just "longer"). Also, having both 能够 and 能力 seems excessive. [I'm not sure what 基本面 is doing at the start here.]


Here 状态 is used to mean "state" (as in "a state of irrationality"). I don't think it's needed.

Combining these ideas, I suggest:

My direct translation: The stock market can maintain irrationality time exceeds your maintain solvency time.
Google Translate: The stock market can remain irrational longer than you can maintain solvency.


“The market can stay irrational longer than you can stay solvent.”

This sentence provides advice to the stock market participants that "the irregular market conditions can stay longer than you can stay afloat with limited capital". IMO, the translation should reflect, and be honest about, the message:


Somebody may have a better thought though.
