From policy tweets to token transfers, those with inside knowledge often act early—leaving tell-tale clues for observant investors. Powerful politicians, corporate insiders, and crypto whales sometimes move assets before market-moving news is released.
This puts everyday investors at a disadvantage when sudden price swings hit. However, by learning how to detect unusual trading activity and whale movements, even beginners can respond faster and potentially profit from these early signals.
This article breaks down the differences between insider trading and market manipulation, provides real examples across stocks and crypto, and outlines practical strategies to help you spot the signs of an incoming “rug pull” or a big move.
Insider Trading vs Market Manipulation: What’s the Difference?
Before diving into the examples, it’s important to clarify key terms. According to the U.S. Securities and Exchange Commission, insider trading occurs when someone trades a security based on material, non-public information—breaching a duty of trust.
For example, a government official who learns about a major policy shift and secretly buys stocks that will benefit is committing illegal insider trading. The same goes for a CEO who sells shares ahead of a poor earnings report.
Market manipulation, on the other hand, involves artificially influencing an asset’s supply, demand, or price. This might include spreading false rumours, coordinating trades to spark a misleading price spike, or distorting quote data.
For instance, someone might tweet misleading news to crash a stock, only to buy it cheaply and profit once the truth emerges.
Both behaviours undermine market fairness—and both have come under intense scrutiny as the public questions whether powerful individuals are “gaming” the system.
Important Note:
Retail traders should never engage in illegal insider trading. However, all strategies discussed here rely solely on publicly available data—such as trading disclosures or on-chain analytics. Reacting to this data, even if it suggests others may be trading on inside information, is legal. In fact, it may help level the playing field.
Suspicious Pre-News Trades: Real-World Examples
The Trump Tariff Tweets & Well-Timed Bets
In April 2025, President Trump shocked markets by first announcing sweeping tariffs—causing a sell-off—only to abruptly reverse course and pause most of them, sending stocks soaring. The S&P 500 gained over 9% in a single day after his reversal.
Hours before the rebound, Trump had tweeted “this is a great time to buy”—raising eyebrows. Meanwhile, mysterious traders had already placed massive bets on a rebound.
One unknown party bought 420,000 S&P E-mini futures contracts right before Trump announced that trade talks with China were “back on track,” earning an estimated $1.8 billion.
Across multiple trades, these unidentified actors are believed to have made $3.5 billion. One veteran trader remarked, “There is definite hanky-panky going on,” referring to how often someone appeared to be perfectly positioned before big headlines.
Congressional Trades Ahead of Market News
During the same volatile period, lawmakers weren’t sitting idle. Over 30 members of Congress executed more than 1,200 stock trades worth up to $28 million during the nine days surrounding Trump’s tariff reversal.
Many of these trades were aligned to benefit from the market’s rebound. Notably, these moves happened before Trump’s public shift in tone.
Although some politicians claim their trades were executed by blind trusts or third-party managers, the timing raised suspicion.
Representative Alexandria Ocasio-Cortez highlighted “interesting chatter on the floor,” calling for full disclosure from any members who traded in the prior 48 hours.
Today, monitoring political trading has become a key red flag for market-savvy retail traders.
Crypto Whale Dump: Ripple’s XRP
Insider moves also plague the crypto world. In July 2025, after a favourable court ruling pushed XRP to $3.60—a multi-year high—a wallet linked to Ripple co-founder Chris Larsen transferred 50 million XRP (worth $175 million) to exchanges and wallets.
Blockchain sleuths soon discovered that about $140 million of it was sold.
XRP plunged 25% to $2.72 within two weeks.
Many retail holders accused Larsen of “dumping” at the top, and the move sparked debate about whether Ripple’s leadership was acting in bad faith.
Regardless, the on-chain data was clear: a large insider had moved significant funds before a major price drop. For those monitoring blockchain wallets, this was a clear early warning.
Tracking Insider Moves in US Stocks
Follow the Smart Money on Capitol Hill
Thanks to the STOCK Act of 2012, members of Congress must disclose their trades—but they have up to 45 days to do so. These delayed disclosures can still reveal valuable patterns.
For instance, Paul Pelosi (husband of former Speaker Nancy Pelosi) famously outperformed the market in 2023 and 2024, posting returns of 65% and 71% respectively—primarily through bets on Nvidia and Alphabet. This success led to the creation of “Congress-tracking” ETFs like NANC (for Democrats) and KRUZ (for Republicans).
Retail traders can use free tools like Capitol Trades or Quiver Quant to see what politicians are buying or selling. Watching clusters of trades in sectors linked to upcoming policy can offer insight. For example, multiple lawmakers buying defence stocks ahead of a Pentagon announcement is a potential signal.
Watch Corporate Insider Filings
Corporate insiders, whether CEOs, board members, or large shareholders, must file Form 4 with the SEC when trading their company’s stock. These filings are public and offer insight into executive sentiment.
You can monitor insider transactions through tools like OpenInsider, Finviz, or directly via the SEC EDGAR database. Clusters of executive buying can indicate bullish internal expectations. Large or sudden selling may signal concern or simple profit-taking. Context matters, but abnormal insider activity is often a precursor to bigger moves.
Unusual Options Activity: A Canary in the Coal Mine
Options markets often reveal insider sentiment before the news. Sharp increases in call or put option volume may indicate that someone expects a big move.
For instance, call volumes on Nasdaq spiked the day before Trump reversed tariffs, suggesting some traders knew what was coming. You can track these patterns using platforms like Unusual Whales, Barchart, or your broker’s scanning tools. Just remember: not all large options activity is insider-driven. Some may be hedging. Use it as one clue, not a certainty.
Crypto: How to Spot the Whales Before They Move
Monitor Whale Wallets Using On-Chain Tools
The blockchain is transparent. Major transfers, particularly from private wallets to exchanges, often precede price action. Tools like Whale Alert provide real-time updates on large token movements.
If a founder or major holder sends tokens to an exchange, that may signal a sell-off. Block explorers like Etherscan or premium tools like Nansen can help track smart money movements.
Watch for Token Unlocks and Distribution Events
Founders or early investors often have locked tokens that eventually become tradable. Sites like TokenUnlocks track these dates. If large amounts are set to unlock soon after a recent price rally, watch out for sell pressure.
Look for Rug Pull Red Flags
“Rug pulls” occur when project developers abandon a token and drain its value. Red flags include:
- Concentrated ownership: A few wallets hold most of the supply.
- Centralised liquidity: Developers control the liquidity pool.
- Suspicious wallet moves: Funds moved to mixers or exchanges before silence.
- Vanishing communication: Projects go quiet or make vague excuses.
Conclusion: How Retail Traders Can Stay One Step Ahead
In a world where a single tweet or whale transfer can swing markets, information is power. Retail traders may not have insider access, but by tracking public signals, they can sharpen their edge. Keep an eye out for blockchain activity, congressional traders, or unusual options flow.
Not every unusual trade leads to a headline. But many headlines leave a trail. The goal is to spot those footprints early, react strategically, and avoid being caught off guard.
Stay vigilant. Stay informed. And trade smart.
