I try to predict Composite bottoming by looking at the 7 biggest market cap stocks.
In the chart, There are two categories of those 7 which are : Underperforming (BBRI, BMRI, and ASII) and Outperforming (BBCA, TLKM, UNVR, and HMSP).
Looking at the total Weight of Outperforming stocks (26.5%) and comparing to the Underperforming stocks (12.7%), we can say that the Outperforming stocks might have more influences on Composite that eventually fastening the Bottoming process.
