I present supportive evidence for the existence of contrast effects in KOSPI market: Salient earnings surprise on the previous trading day inversely biases return reactions to todays earnings announcements, conditional on todays earnings surprise. In explaining the results, I identify the contrast effects hypothesis as the most plausible explanation compared to alternative stories involving information transmission, risk and liquidity, and strategic timing of earnings announcements.๋Œ€์กฐํšจ๊ณผ(contrast effect)๋Š” ์„ ํ–‰ ๊ด€์ธก์น˜์˜ ๊ฐ’๊ณผ ํ›„ํ–‰ ๊ด€์ธก์น˜์˜ ๊ฐ’์— ๋Œ€ํ•œ ์ง€๊ฐ(perception) ์‚ฌ์ด์— ์Œ์˜ ์ƒ๊ด€๊ด€๊ณ„๋ฅผ ๋งŒ๋“ ๋‹ค. ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ์ฃผ์–ด์ง„ ์‹ค์ ๊ณต์‹œ์— ๋Œ€ํ•œ ์‹œ์žฅ๋ฐ˜์‘์ด 1๊ฑฐ๋ž˜์ผ ์ „์˜ ์ฃผ์š”ํ•œ(salient) ์–ด๋‹์„œํ”„๋ผ์ด์ฆˆ์— ์˜ํ•ด ๊ทธ์™€ ๋ฐ˜๋Œ€ ๋ฐฉํ–ฅ์œผ๋กœ ํŽธํ–ฅ๋จ์„ ๋ฐœ๊ฒฌํ•จ์œผ๋กœ์จ, ํ•œ๊ตญ ์œ ๊ฐ€์ฆ๊ถŒ์‹œ์žฅ์— ๋Œ€์กฐํšจ๊ณผ๊ฐ€ ๋‚˜ํƒ€๋‚จ์„ ์ง€์ง€ํ•˜๋Š” ๊ฒฐ๊ณผ๋ฅผ ์ œ์‹œํ•˜์˜€๋‹ค. ์ด๋Ÿฌํ•œ ๊ฒฐ๊ณผ๋Š” ์ •๋ณด ์ „๋‹ฌ, ๋ฆฌ์Šคํฌ ๋ฐ ์œ ๋™์„ฑ, ์‹ค์ ๊ณต์‹œ์˜ ์ „๋žต์  ์‹œ์  ์„ ํƒ ๋“ฑ์— ๊ธฐ๋ฐ˜ํ•œ ๋Œ€์•ˆ ๊ฐ€์„ค๋ณด๋‹ค ๋Œ€์กฐํšจ๊ณผ ๊ฐ€์„ค๋กœ ๊ฐ€์žฅ ์ž˜ ์„ค๋ช…๋œ๋‹ค.1.
