Indonesia’s Warren Buffett Reveals Five Stock Selection Rules and Playbook for Surviving Five Financial Crises

JAKARTA, Investortrust.id — Veteran equity investor Lo Kheng Hong has revealed his core stock selection framework and crisis-management playbook, detailing the principles that enabled his portfolio to endure five major market crashes across a 37-year investment career on the Indonesia Stock Exchange (IDX).

Speaking at the Capital Market Summit & Expo (CMSE) 2026 at the IDX Main Hall in Jakarta on Thursday, the investor widely regarded as Indonesia’s Warren Buffett noted that avoiding debt entirely and maintaining rigorous fundamental underwriting enabled him to weather turbulent downturns in 1991, 1998, 2008, 2020, and 2026. His screening process relies on five non-negotiable parameters: executive integrity, defensive business positioning, sustainable profit expansion, depressed valuation multiples, and generous dividend distributions.

To guard against speculative blind spots, Lo conducts extensive annual report analysis before deploying capital into any public company.

“Before I buy shares in a company, I will definitely examine its annual report,” Lo said. “I do not want to buy a pig in a poke, so I must know what I am buying. I open the annual report, and I look at who the majority shareholder is, who is on the board of directors, and who serves on the board of commissioners.”

Integrity and Industry Positioning

The primary filter in Lo’s evaluation process is the caliber and ethical track record of corporate leaders. He noted that controlling shareholders, directors, and commissioners directly dictate capital allocation and corporate governance, requiring investors to scrutinize executive history before taking positions.

On sector dynamics, Lo deliberately avoids companies whose products compete directly with low-cost manufacturers from China and India, whose competitive pricing can compress operating margins. Instead, he targets industries whose output is actively consumed by those two economic powers, pointing specifically to Indonesian thermal coal and crude palm oil (CPO) producers.

“I look for companies that do not compete with China and India, but rather those that sell to China and India,” Lo said. “For example, coal and palm oil, because oil palm cannot be grown in China or India.”

Earnings Power, Discounted Multiples, and Dividends

Lo insists that target companies generate substantial net earnings and maintain continuous profit trajectories, steering clear of unprofitable or marginally profitable issuers. He characterized highly profitable enterprises as self-sustaining capital compounders.

“Owning a highly profitable company is just like owning a money printing machine,” he said.

Attractive operating performance must be paired with low valuation multiples, specifically low price-to-earnings (P/E) and price-to-book value (P/B) ratios. Lo warned that paying excessive premiums for sound companies introduces balance sheet risk, whereas acquiring assets at low multiples provides a built-in margin of safety.

He also prioritizes cash returns through substantial dividend yields, which allow long-term shareholders to monetize their investments without participating in daily operations.

“As a sleeping shareholder, we do not work, yet we receive a handsome salary if the dividend yield reaches 14%,” Lo said. “There is no need to work; as a sleeping shareholder, I do not work.”

Navigating Five Market Downturns Without Debt

Beyond equity screening, Lo credited his survival through systemic financial shocks to an absolute refusal to use leverage or margin financing. By funding all stock purchases with unencumbered cash, he avoided margin calls and forced liquidations during severe market routs.

“I was able to get through various crises over 37 years because I have no debt,” Lo said. “I buy shares using only my own money. I have no debt, so I can survive various crises.”

During the 1991 monetary tightening episode, government efforts to rein in 8% inflation squeezed banking liquidity and cut Lo’s portfolio value by 50%. The position rebounded into profit as price pressures subsided and liquidity loosened between 1991 and 1993.

The Asian Financial Crisis of 1998 delivered a far more acute test, as currency depreciation and interest rates peaking near 70% pushed indebted corporations into default and wiped out 85% of his portfolio value on paper. Lo treated the crash as a liquidity windfall to purchase undervalued assets.

“The 1998 crisis was immense; the shower of gold in 1998 was extraordinarily large,” Lo said. “I saw my portfolio drop 85%. I was no longer working, my wife was a homemaker, I had two children, and only 15% of my money remained. But in 1998, I found a Mercedes-Benz being sold at the price of a bajaj, and diamonds being sold at the price of gravel, so I survived once again.”

During the 2008 Global Financial Crisis, domestic economic resilience helped limit the duration of local market losses. Lo cited Warren Buffett’s playbook of acquiring beaten-down U.S. financial stocks during that period as an example of long-term value compounding.

When the Covid-19 shock hit equities in 2020, and again during market declines in 2026, Lo deployed accumulated cash reserves to buy undervalued companies at significant discounts.

“Fortunately, at that time I held substantial cash balances, which allowed me to buy up shares at cheap prices,” Lo said. “Likewise, in 2026, when stock prices fell, I had ample cash to buy up cheap stocks.”

Prudence and Capital Accumulation for Retail Investors

Lo cautioned the expanding cohort of young retail investors against momentum chasing and the fear of missing out (FOMO), urging them to anchor portfolio decisions in business fundamentals.

For university students entering the market, he advised completing their education before focusing on professional earnings to generate investable capital. He noted that high income provides little compounding advantage if not paired with disciplined spending and simple living.

“You must live frugally and simply,” Lo said. “Earning a large sum of money is useless if you are wasteful; it will simply run out. You must live simply and frugally so that you have ample surplus cash to purchase shares of wonderful companies, and over time, you can become wealthy.”

Lo concluded that disciplined long-term equity investing remains one of the most reliable vehicles for personal wealth creation.

“Being a stock investor is one of the best occupations in the world,” Lo said.
