How to Arrange Anti-Flop Investment Assets for Mums in the Style of Sandiaga Uno - Bareksa.com
Often feeling like money is constantly flowing out but assets aren’t growing? The issue is frequently not a lack of income, but rather how money and risks are managed.
Quoting a post from the official Instagram reel of Sandiaga Uno (9/4), investment isn’t just about chasing big profits, but about arranging a portfolio to remain safe in various market conditions.
This is evident from Sandiaga’s experience when asked to manage his mother Mien R. Uno’s assets, an education figure now aged 84, accumulated over decades as a teacher.
Sandi was surprised. Although she had been investing for more than 15 years, the composition of his mother’s portfolio was quite aggressive, with a 40% allocation to stocks.
However, for a conservative investor profile like “mums,” this composition is considered less ideal because it isn’t balanced with the needs for stability and security.
Initial Composition
40% stocks (equity)
40% fixed income
20% cash (deposits/savings)
Note:
The stock allocation is relatively high, while cash is substantial, making part of the funds unproductive.
After Sandiaga completed his last government role as Minister of Tourism and Creative Economy (22 December 2020 – October 2024), the former Deputy Governor of DKI Jakarta (2017–2022) then rebalanced his mother’s investment portfolio.
After Rebalancing
The portfolio was adjusted to be more stable:
20% stocks (equity)
60% fixed income
20% cash & gold
With this rebalancing, Mien Uno’s investment portfolio is expected to be more resilient to market fluctuations. Additionally, it provides regular income from fixed income instruments like State Securities (SBN), while still offering growth potential from stocks and gold. Liquidity is also maintained through cash.

There is no exact formula for ideal asset allocation for everyone, as it depends greatly on risk profile, age, needs, and investment goals.
However, there is a simple approach often used as an initial guide: the formula of 100 minus age to determine the allocation for aggressive assets like stocks.
For example, if the investor is 40 years old, the stock allocation is around 60% (100 – 40), while the remaining 40% is placed in more conservative instruments like money market mutual funds, bonds, or gold.
As age increases, the allocation to aggressive assets is generally reduced. Senior investors are usually advised to increase allocation to defensive or conservative instruments, as they tend to prioritise stability and avoid market volatility risks over high growth.
For the example of Mien Uno, who is 84 years old, Sandiaga applied a similar pattern. He allocated only 20% to stocks, with the rest in defensive and conservative instruments.
Moreover, in recent times since Israel-United States attacked Iran at the end of February, escalating geopolitical conflict in the Middle East, markets have been volatile and stock performance has suffered losses.
The JCI recorded a minus 9.44% and the LQ45 Index dropped 10.53% up to the end of last week.

By increasing the allocation to fixed income instruments and gold, Sandiaga successfully kept his mother’s portfolio performance safe from market turbulence and still achieved positive returns.
As a simple illustration, here is the performance of Mien Uno’s investment portfolio, for example with Rp1 billion funds, divided into several investment allocations as follows:
Simulation of Rp1 Billion Portfolio: Before vs After Rebalancing
Before Rebalancing
Total portfolio: Rp1 billion
40% stocks (Rp400 million): LQ45 stocks like SRTG, BBCA, BMRI, BBRI
40% fixed income (Rp400 million):
Rp200 million fixed income mutual funds (return ±7.44% per year)
Rp200 million Retail State Sukuk SR021 (coupon 6.35%–6.45%) offering period 23 August - 18 September 2024.
20% deposits (Rp200 million): interest ±4.25% (according to LPS at that time)
After Rebalancing
Total portfolio: Rp1 billion
20% stocks (Rp200 million): LQ45 stocks (SRTG, BBCA, BMRI, BBRI)
60% fixed income (Rp600 million):
Rp300 million fixed income mutual funds (return ±8.6% per April 2026)
Rp300 million Savings Sukuk ST013 (yield 6.4%–6.5%) offering period: 8 November - 4 December 2024.
20% defensive assets (Rp200 million):
Rp100 million deposits (interest ±4.25%)
Rp100 million gold (price rose from Rp1,446,214 → Rp2,604,290 per gram per 13 April 2026)

From the chart, investing in digital gold in October 2024 at a purchase price of Rp1.44 million per gram, then selling again on 13 April 2026 when the price breaks Rp2.6 million per gram, could yield an 80% profit.
For stocks with Mien Uno’s risk profile, the portfolio is assumed to be placed in LQ45 stocks, such as PT Saratoga Investama Sedaya Tbk (SRTG), PT Bank Mandiri Tbk (BMRI), PT Bank Rakyat Indonesia to PT Bank Central Asia Tbk (BBCA).
