Window dressing refers to a strategy that is often used by fund and portfolio managers to improve the appearance of a fund's performance before presenting it to clients. The fund manager sells those stocks that have weakened in value and purchases those stocks that surged in value. This strategy is often applied before the end of a quarter.

It is also possible that after the nine-day losing streak investors are bargain-hunting on Tuesday and Wednesday. For example, shares of Astra International and Unilever Indonesia. Moreover, the year 2017 is expected to be a good one for Indonesian stocks as domestic economic growth is expected to accelerate amid improving purchasing power, higher commodity prices and government-led investment. Various analysts believe that Indonesia will outperform other emerging markets.

Overnight, Wall Street rose amid thin trade with the Nasdaq touching a new record supported by rising technology shares (although the Dow Jones Industrial Average, again, failed to touch the psychological boundary of 20,000 points). Meanwhile, higher crude oil prices add positive sentiments to the trading day in Asia. Oil is trading at the highest level so far this year.
