SINGAPORE — A familiar investment scam is making a comeback — and Singapore Police are warning investors to be especially careful when strangers or online “trading experts” promise a little-known stock is about to surge.
At least 21 cases of suspected “pump-and-dump” stock market manipulation scams have been reported since July 2026, according to an advisory issued by the Singapore Police Force on Sept. 5.
The victims were allegedly persuaded to buy shares in companies listed on the Hong Kong or US stock exchanges, often after being told the companies had strong growth potential and that their share prices were expected to rise sharply.
But in at least one case, five victims collectively bought more than one million shares in a Hong Kong-listed company after receiving a recommendation from an alleged “expert”.
Within a week, the share price plunged by almost 75 per cent, leaving the victims with combined losses exceeding HK$4.6 million — about S$744,000.
The trap starts with a “hot stock”
The scam typically begins on social media or messaging platforms such as Facebook and WhatsApp.
Fraudsters may present themselves as experienced investors, professional traders or mentors offering investment advice.
Some may initially recommend stocks that perform well.
That early success is crucial.
It can convince victims that the person behind the account genuinely understands the market.
Once trust has been established, the victim may be introduced to a supposedly “high-potential” company whose share price is allegedly about to rise dramatically.
The pressure then begins.
Victims may be strongly urged to buy the shares immediately after the company is revealed, according to police.
Then comes the “pump”
The name of the scam describes what happens next.
In the “pump” phase, fraudsters attempt to create artificial demand for a particular stock.
They may spread false or misleading claims about the company or create the impression that many investors are buying.
As more unsuspecting investors purchase the shares, demand can push the price higher.
To someone watching the market, the sudden price increase can appear to confirm the fraudsters’ claims.
But the apparent momentum may be artificial.
The “dump” can happen next
Once the price has been pushed sufficiently high, the fraudsters allegedly sell their own holdings.
That is the “dump” phase.
When the artificial buying pressure disappears, the stock can fall rapidly.
Victims who bought at the inflated price can then be left holding shares worth substantially less than what they paid.
Singapore Police have described pump-and-dump schemes as a form of stock market manipulation, warning that the resulting collapse can cause substantial losses to unsuspecting investors.
Some scammers even monitor whether victims bought
The operation can involve more than a single person sending stock tips.
Police said accomplices may be planted inside investment chat groups.
They can pose as administrators, assistants or fellow investors and privately contact victims after they make a purchase.
Victims may be asked to provide an update or send proof of their completed trade, such as a screenshot of their transaction.
Police believe some accomplices may be rewarded according to the number of people they successfully persuaded to invest — which would explain why proof of the purchase is allegedly requested.
The scammers may even promise to cover the losses
In some cases, victims are reportedly told that their trading losses will eventually be reimbursed.
But once the scheme begins to unravel, the people behind it may become unreachable or provide excuses for why the promised reimbursement has not arrived.
By then, the victim may already have suffered a substantial loss.
Why overseas small-cap stocks are a warning sign
Police are urging investors to be particularly skeptical of overseas-listed companies with low liquidity and small market capitalisation.
Such stocks may be more susceptible to price manipulation because relatively limited trading activity can make abnormal price movements easier to create.
That does not mean every small or overseas-listed company is fraudulent.
Rather, the combination of an unfamiliar overseas stock, an unsolicited recommendation and urgent pressure to buy should raise serious questions.
Singapore has seen investment scams evolve
The resurgence of pump-and-dump schemes comes amid a broader investment-scam problem.
Singapore recorded 2,256 investment scam cases in the first half of 2026, with losses reaching about S$169.8 million, making investment scams the scam category with the highest total losses during the period.
Police have also warned about newer schemes involving fake investment-learning communities.
In one recent variant, victims were drawn into WhatsApp groups after seeing online advertisements offering supposedly free investment education. Fake mentors then supplied stock tips and other investment advice while fake group members posted purported success stories to build credibility.
The methods may change, but the psychological strategy remains similar: build trust first, create urgency next, then persuade the victim to hand over money.
Even real-looking investment groups can be fake
One reason these schemes can be difficult to spot is that victims may see what appears to be a genuine community of investors.
There may be administrators answering questions, members discussing profits and screenshots showing successful trades.
But some of those accounts may actually be controlled by the scammers.
The apparent popularity of the investment opportunity therefore cannot be treated as proof that it is legitimate.
Police previously warned that fraudsters could establish investment chat groups and pose as trading experts, sometimes first giving recommendations that appeared successful before introducing victims to a supposedly high-quality stock.
What investors should watch for
Police are urging members of the public to remain skeptical of stock tips provided online or by people they have never met personally.
Several warning signs should immediately raise concern:
- An unknown person suddenly offers investment advice.
- You are invited into a WhatsApp or social-media investment group.
- Someone claims to have special or exclusive information about a stock.
- You are told a particular share is about to surge.
- You are pressured to buy immediately.
- Other group members appear to be making easy profits.
- You are asked to send screenshots proving that you bought the stock.
- Someone promises that your losses will be reimbursed.
- The stock is unfamiliar, thinly traded or listed overseas.
Most importantly, no legitimate investment strategy can guarantee profits.
The lesson from the latest losses
The biggest danger is not necessarily the stock itself.
It is the story built around it.
A fraudster does not need to convince a victim that investing is profitable in general. They only need to convince the victim that this particular opportunity is special, urgent and trusted by everyone else.
By the time the victim realizes that the apparent momentum was manufactured, the people who orchestrated the scheme may already have exited.
And the money can be gone.
If a stranger tells you that a little-known stock is about to explode — and insists you buy before everyone else — that urgency may be the biggest warning sign of all.
Editorial accuracy note
The Singapore Police Force says at least 21 suspected pump-and-dump scam cases have been reported since July 2026. The police advisory describes the activity as a form of stock market manipulation. Individual cases should be described as suspected scams unless there has been a conviction or other official finding establishing criminal liability.
The reported HK$4.6 million loss involved five victims who allegedly bought more than one million shares in a Hong Kong-listed company; the stock subsequently fell by almost 75 per cent in a week.
This resurgence should also be viewed separately from legitimate losses suffered through ordinary market volatility. A falling stock price by itself does not prove a pump-and-dump scheme.
