moatとは 意味・読み方・使い方

語源

From 中期英語 mote, from Old French mote (“mound, embankment”); compared also to Old French motte (“hillock, lump, clod, turf”), from Medieval Latin mota (“a mound, hill”), of Germanic origin, perhaps via Frankish *mot, *motta (“mud, peat, bog, turf”), from Proto-Germanic *mutô, *mudraz, *muþraz (“dirt, filth, mud, swamp”), from Proto-Indo-European *(s)mut- (“dark, dirty”).

Cognate with Alemannic German Mott, Mutte (“peat, turf”), Bavarian Mott (“peat, turf”), dialectal Dutch mot (“dust, fine sand”), Saterland Frisian mut (“grit, litter, humus”), Swedish muta (“to drizzle”), 古期英語 mot (“speck, particle”). More at mote, mud, smut.

As term for a business strategy, popularized by American investor Warren Buffett.

     No matter how good your company's product is or how quickly the industry is growing, if there is no moat, competitors will invade your castle and burn it down.

   • 2018 May 7, Andrew Ross Sorkin, quoting Elon Musk, “Elon Musk Wants to Fill Warren Buffett’s ‘Moat’ With Candy, but It Still Holds Water”, in The New York Times‎, →ISSN:

     “I think ‘moats’ are lame,” Mr. Musk had said during a Tesla earnings call. It was a criticism of an economic principle that Mr. Buffett had coined in 1999 and that has become something of a mantra for his faithful: Invest in businesses “that have wide, sustainable moats around them.”

   • 2023 November 28, JS Tan, “It's All Bullshit”, in The Baffler‎:

     Moreover, where older firms might have to stave off competitors and engage in practices like predatory pricing to keep the competition at bay, platform monopolies have a built-in moat. Since a platform’s value comes from its number of users—a phenomenon known as the network effect—competing against large platforms is nigh impossible since its monopoly position makes it inherently more useful.

3. A circular lowland between a resurgent dome and the walls of the caldera surrounding it.
4. (meteorology) A clear ring outside the eyewall of a tropical cyclone.
5. (obsolete) A hill or mound.
