carry的书面意思就是拿着,持有。你或者持有一个东西,或者先把东西借过来卖掉(即持有货币)而后再买回来还给别人,都是在持有something。这个something肯定是未来可以给你带来收益的。
以currency carry trade为例,investpedia有一个例子:
Here's an example of a "yen carry trade": a trader borrows 1,000 Japanese yen from a Japanese bank, converts the funds into U.S. dollars and buys a bond for the equivalent amount. Let's assume that the bond pays 4.5% and the Japanese interest rate is set at 0%. The trader stands to make a profit of 4.5% as long as the exchange rate between the countries does not change. Many professional traders use this trade because the gains can become very large when leverage is taken into consideration. If the trader in our example uses a common leverage factor of 10:1, then she can stand to make a profit of 45%.
The big risk in a carry trade is the uncertainty of exchange rates. Using the example above, if the U.S. dollar were to fall in value relative to the Japanese yen, then the trader would run the risk of losing money. Also, these transactions are generally done with a lot of leverage, so a small movement in exchange rates can result in huge losses unless the position is hedged appropriately.
这个例子中,trader carry的就是U. S. 4.5% bond。
cost of carry 可以理解为持有something的成本。比如持有100吨大米3年,在这个过程中你得保护好它,别发霉,别让火烧了。。。。都是成本
