摘要： This thesis investigates short-term momentum anomaly in Finnish stock markets during 2010-2019. Momentum anomaly has been persistent on the financial markets and finan-cial market literature since it was first founded. Momentum effect is stock prices' tenden-cy to follow pattern where previous winners tend to win in future and previous loser tend to lose in future. From which has been generated strategy where investor takes long posi-tion in prior winners and short position in prior loser stocks. Momentum anomaly is generally examined in 3 to 12-month periods. To broaden the momentum anomaly related literature this thesis examines the anomaly in 1-month peri-od in Finnish stock markets. The findings of this study show that stock's age in the stock exchange has positive relation-ship to future's stock price. All other regression results we not statistically significant and did not indicate that short-term momentum anomaly exists in the Finnish stock markets. The short-term momentum effect can still exist in the Finnish stock markets in certain industries. The effect may be vanished due to normal volatility inside the sample. The topic of this thesis is extremely interesting and with different kind of approach and data categorization the effect can possibly be found.
