What the numbers on Finji mean and how they are made. Nothing here is investment advice.
Today's market verdict
After each Korean trading day Finji scores ten factors — five short-term, five long-term. Each factor adds +1, 0 or −1. A total of +2 or more is Good, −2 or less is Careful, anything between is Neutral. The chips under the verdict show every factor's value and sign, so the score can always be checked by hand.
Short-term (days to two weeks)
| Factor | Rule |
|---|---|
| 코스피 20일선 | 종가가 20일선 위면 +1, 아래면 −1 |
| 등락 종목 비율 | 코스피·코스닥 전체 상승 종목 비율 55% 이상 +1, 40% 이하 −1 |
| 외국인·기관 수급 | 코스피 외국인+기관 당일 순매수 +2,000억 이상 +1, −2,000억 이하 −1 |
| 변동성 (VIX) | 최근 VIX 18 미만 +1, 25 초과 −1 |
| 최근 5일 흐름 | 코스피 5거래일 수익률 +1.5% 이상 +1, −1.5% 이하 −1 |
Long-term (one to three months)
| Factor | Rule |

| 코스피 60·120일선 | 둘 다 위 +1, 둘 다 아래 −1 |
| 60일선 기울기 | 60일선이 20거래일 전보다 1% 이상 높으면 +1, 1% 이상 낮으면 −1 |
| 20일선 위 종목 비율 | 전체 55% 이상 +1, 40% 이하 −1 |
| 52주 신고가·신저가 | 신고가 종목이 신저가의 2배 이상 +1, 그 반대 −1 |
| 최근 3개월 흐름 | 코스피 63거래일 수익률 +5% 이상 +1, −5% 이하 −1 |
요인 합계 +2 이상 = 좋아요, −2 이하 = 조심해요, 그 사이 = 보통. On holidays the last trading day's verdict stays up.
A stock's market position
Every Korean stock (KOSPI and KOSDAQ, SPACs excluded) gets a percentile rank from 1 to 99 for its 1-, 3-, 6- and 12-month returns, measured against all other stocks on the same day. 99 means it beat almost every stock; 1 means it trailed almost all of them.
- Composite weights the last three months twice: 0.4 × 3-month + 0.2 × 6-month + 0.2 × 9-month + 0.2 × 12-month return, then ranked.
- 52-week high / low use the last 252 trading days including today. "New high" means today's high exceeded the previous 252-day high (stocks listed under 120 days are not counted).
- Moving averages compare today's close with the 20-, 60- and 120-day simple averages.
- Updated once a day after the close. The date shown on the card is the close it was computed from.

Glossary
- Advancers / decliners
- How many stocks closed up, down or unchanged. The bar shows the three shares of the whole market.
- Limit-up / limit-down
- Korean stocks can move at most ±30% a day. Finji counts ±29.5% or more as hitting the limit.
- Trading value
- Price × volume for the day — where the money actually went.
- Execution strength
- Buy-initiated volume divided by sell-initiated volume, ×100. Above 100 means buyers were more aggressive.
- Investor flows
- Net buying by foreigners, institutions and individuals. Positive = net bought.
- Overnight reference price
- An estimate of where a Korean stock would trade after hours, built from its NXT after-market price and related US-listed instruments (such as ADRs). A reference, not a quote.
- NXT
- Nextrade, Korea's alternative exchange with pre-market (08:00) and after-market (to 20:00) sessions.
- VIX
- The US volatility index. Below 18 is calm, above 25 is nervous — one of the short-term verdict factors.
- Percentile
- Where a value sits among all others, 1 to 99. 90 means higher than 90% of stocks.
- Close betting / open betting
- Short-term approaches that look for stocks to hold from the close into the next morning (close betting) or to enter right after the open (open betting). Finji lists candidates and the reasons; the decision is yours.
