The case for “outperformance”
Here’s the evidence in favor of marrying “out” and “performance” so they’re one word:
- “Generally do not hyphenate when using a prefix with a word that starts with a consonant,” says The Associated Press Stylebook. Note: I’m using the 2007 version of the AP Stylebook.
- Words into Type agrees, saying “The modern tendency is to eliminate the hyphen between a prefix and a root unless the root is a proper noun or adjective, such as un-American.”
- Google brings up about 1.2 million examples for “+fund +outperformance” vs.fewer than 700,000 for “+fund +out-performance.”
The case for “out-performance” with a hyphen
I mustered one piece of evidence in favor of hyphenating “out-performance.” Google yields more than 931 million search results for “out-performance” vs. only 1.01 million for “outperformance.” It’s strange that the first four results use the spelling “outperformance,”as you see in the screen shot on the left.
