KUALA LUMPUR, June 25 — The ringgit is expected to appreciate slightly while moving in a tight range at around 4.40 against the greenback next week on mixed market sentiments, said an economist.

Bank Islam Malaysia Bhd chief economist Mohd Afzanizam Abdul Rashid said key data points from the United States (US) would be the core personal consumption expenditures (PCE) inflation for May as well as the house price index, that is the S&P Case Shiller Index, which is likely to stay elevated.
