Stock Investment Strategy 2026, Hunting for Bluechip or Konglo Stocks? This is what the founder of Mikirduit said

JCI recorded a record after recording 24 all time highs throughout 2025 with an increase of 21.92 percent. This is the highest increase since 2011.

Founder and CEO of Mikirduit Surya Rianto said, JCI has indeed recorded many good records, such as the market cap reaching IDR 16,000 trillion and an all time high of 24 times. However, it is noted that the increase in the JCI was driven by a series of conglomerate shares that were previously illiquid, but were moved up so that their market cap was quite large.

“Some stocks that have skyrocketed and can be considered to support the JCI include DSSA, DCII, BRPT, MORA, CUAN, and IMPC which has a jumbo market cap scale, but the increase in one year is more than 100 percent. Apart from that, the increase in the JCI market cap was also driven by several jumbo IPOs from CDIA, EMAS, to SUPA,” he said.

Euphoria for conglomerate shares will indeed reach its peak in 2025. From Prajogo Pangestu, Bakrie, to Happy Hapsoro.

On the other hand, classic stocks with good fundamentals and a large weighting in the IHSG such as big banks, namely BBCA, BBRI, BMRI, BBNI, and ASII are starting to be left out of the top market cap.

BBCA was overtaken by BREN from number one position, BBRI was pushed to 5th place, BMRI to 8th place, TLKM to 10th, and ASII fell to 13th.

Solar reminded, historically, when the JCI rose quite significantly in one year, especially above 20 percent. In the following year there is potential for correction.

This happened in 2014 when the IHSG rose 21.71 percent in a year, then in 2015 it fell 11.3 percent. Likewise in 2017 when the JCI rose 20.14 percent, then in 2018 it fell 2.7 percent.

“Essentially, investors must remain rational regarding the high rise in conglomerate share prices. The MSCI narrative is still there, but the global index is planning to change to a stricter scheme for Indonesian shares which will be announced at the end of January 2026,” he said.

MSCI had indeed expressed plans to change the free float provisions on Indonesian shares by using KSEI data, as well as excluding free float based on domestic limited liability companies, and others. Then, plans to say rounding up Indonesian shares. IDX has provided input to MSCI, but the final choice is in the hands of the global index owner.

Solar “We suggest that investors can monitor developments first before they enter the stock market in 2026.”You can use a risk management strategy by entering gradually, as well as analyzing the prospects for the shares you want to buy. “Does it have medium-term momentum or not, and is the volatility too high or is it still at a reasonable level,” he said.
