How to Detect Stock Scams

A step-by-step guide to identifying pump-and-dump schemes, manipulation patterns, and red flags that signal investment fraud.

Step 1: Research the Company Fundamentals

Start with the basics. Legitimate companies maintain transparent financial records, clear business models, and verifiable management teams.

What to Check

  • SEC filings (10-K, 10-Q forms) on Edgar.sec.gov
  • Company website and contact information
  • Management team backgrounds and credentials
  • Business model clarity—can you explain what they sell?
  • Revenue history and growth trajectory
  • Industry position vs. competitors

Step 2: Analyze Trading Patterns

Pump-and-dump schemes create distinctive patterns in price and volume. Legitimate stocks show gradual, sustainable growth. Manipulated stocks show sudden, intense activity.

Red Flag Patterns

  • 300%+ price spike in days or weeks with high volume
  • Volume spikes with no corresponding company news
  • Price movements inversely correlated with market
  • Unusual after-hours trading activity
  • High short interest followed by aggressive promotion
  • Trading halts or SEC trading suspensions

Step 3: Evaluate Promotional Activity

Scammers rely on aggressive marketing to drive up prices quickly. Watch for coordinated hype, especially on social media.

Hype vs. Legitimate News

🚩 Scam Indicators

  • Unsolicited investment tips from strangers
  • Promises of 'guaranteed returns' or 'inside information'
  • Pressure to buy immediately ('limited time offer')
  • Same message repeated across multiple channels
  • No logical connection between news and stock price move

✓ Legitimate News

  • Official press releases from company IR
  • News from major financial media outlets
  • SEC filing announcements
  • Earnings reports or strategic partnerships
  • Gradual price appreciation over time

Step 4: Check Regulatory Status

The SEC maintains lists of suspended securities and enforcement actions. Companies with regulatory issues are high-risk.

Where to Check

  • SEC.gov Trading Suspensions — for halted companies
  • FINRA BrokerCheck — verify broker legitimacy
  • OTC Markets Group — check listing status
  • Company CIK number — find all SEC filings

Step 5: Use Analytical Tools

Advanced tools can automatically detect pump-and-dump signals, analyze behavioral patterns, and calculate risk scores.
