The Big Bull: Harshad Mehta Scam (1992)
The Man Who Moved Markets
Harshad Mehta, a former salesperson, became India’s biggest stock market celebrity in the early 1990s. He drove a Lexus when most Indians had never heard of the brand. His stock picks were gospel.
The Scheme
Mehta exploited a loophole in the banking system called the Ready Forward (RF) deal.
How RF Deals Worked:
Bank A needs cash → Sells government securities to Bank B
After agreed period → Buys them back at slightly higher price
The Fraud:
Step 1: Mehta convinced banks to issue fake Bank Receipts (BRs)
Step 2: These BRs became collateral for more borrowing
Step 3: The borrowed money went into stocks
Step 4: Stocks rose → More BRs issued → More borrowing → Repeat
The Scale
- Amount Siphoned: ₹3,500 crores (₹35,000 crores in today’s money)
- Stocks Manipulated: ACC (₹200 → ₹9,000), Videocon, Sterlite
- Duration: 1990-1992
The Crash
In April 1992, journalist Sucheta Dalal exposed the scam. The Sensex crashed from 4,500 to 2,500 (44% fall).
Thousands of retail investors who bought at the peak lost everything.
Aftermath
- Harshad Mehta: Arrested, 27 criminal cases, died in custody (2001)
- Banking reforms: Complete overhaul of securities settlement
- SEBI empowered: Given real regulatory teeth
Lesson for Investors
Red Flag: Any stock rising 4,000% (like ACC) without corresponding business growth is suspicious. If something seems too good to be true, it usually is.
The Pied Piper: Ketan Parekh Scam (2001)
The New Big Bull
After Harshad Mehta’s fall, Ketan Parekh rose to prominence. He was more sophisticated, focusing on tech stocks during the dot-com boom.
The K-10 Stocks
Parekh created a group of “favorite” stocks called K-10:
- Himachal Futuristic
- Global Trust Bank
- Zee Telefilms
- HFCL
- Aftek Infosys
- Padmini Polymer
- Visual Soft
- DSQ Software
- Silverline Technologies
- Pentamedia Graphics
The Scheme
Circular Trading:
Company A buys from Company B at ₹100
Company B buys from Company A at ₹110
Company A buys from Company B at ₹120
... Stock price "rises" artificially
Pay Order Fraud:
Parekh obtained "pay orders" from banks (like bank guarantees)
Used them to borrow from stock markets
But pay orders weren't backed by actual funds
The Scale
- Manipulated Amount: ₹1,000+ crores
- Stocks Affected: K-10 stocks fell 70-90%
- Banks Involved: Madhavpura Mercantile Cooperative Bank collapsed
The Crash
March 2001: The tech bubble burst globally. K-10 stocks, artificially inflated, crashed brutally.
| Stock | Peak Price | Crash Price | Fall |
|---|---|---|---|
| Himachal Futuristic | ₹2,500 | ₹5 | 99.8% |
| DSQ Software | ₹3,000 | ₹30 | 99% |
| Visual Soft | ₹8,000 | ₹100 | 98.7% |
Aftermath
- Ketan Parekh: Banned from markets for 14 years
- UTI US-64 crisis: Linked to Parekh, triggered UTI bailout
- Reforms: Badla (carry forward) system banned
Lesson for Investors
Red Flag: Stocks trading at extreme valuations (P/E 500+) with no profits are speculation, not investment. The tech bubble mentality of “new paradigm” is always dangerous.
The Corporate Fraud: Satyam Scam (2009)
India’s Enron
Satyam Computer Services was India’s fourth-largest IT company, listed on NYSE. Its chairman, B. Ramalinga Raju, was celebrated as a visionary.
On January 7, 2009, Raju confessed in a letter:
“What started as a marginal gap between actual operating profit and the one reflected in the books continued to grow over the years…”
The Fraud
Fake Cash:
- Books showed: ₹5,361 crores cash
- Actual cash: ₹321 crores
- Fabricated: ₹5,040 crores (94% fake!)
Fake Revenue:
- Fake invoices to non-existent clients
- 13,000 fake employees on payroll
- Forged bank statements
How It Went Undetected:
1. PwC (auditor) signed off on fake balance sheets
2. Independent directors didn't question
3. "Reputed" company got benefit of doubt
4. Employee checks were deposited into promoter accounts
The Scale
- Fake Assets: ₹7,000+ crores
- Stock Crash: ₹544 → ₹6.30 (98.8% fall in one day!)
- Market Cap Lost: ₹20,000+ crores
Aftermath
- Ramalinga Raju: Arrested, 7 years in prison
- PwC India: Banned for 2 years
- Satyam: Acquired by Tech Mahindra (renamed Mahindra Satyam, then merged)
- Reforms: Stricter auditor accountability, independent director rules
Lesson for Investors
Red Flag:
- Cash-rich companies that don’t pay dividends or buy back shares
- High revenue growth with low employee additions
- Related party transactions (Raju was diverting to family real estate)
The Pump and Dump: NDTV Scam (Various)
How Pump and Dump Works
Phase 1 (Accumulate): Operator quietly buys shares at low price
Phase 2 (Pump): Spread positive rumors, pay for "tips," social media hype
Phase 3 (Peak): Share price multiplies
Phase 4 (Dump): Operator sells at peak
Phase 5 (Crash): Stock collapses, retail investors stuck
Warning Signs of Pump and Dump
- Unknown stock suddenly trending on social media
- WhatsApp/Telegram “tips” with urgent “buy now” messages
- Volume spikes without any news
- Stock rising 10-20% daily for no reason
- “Promoter buying” rumors from unofficial sources
Real Examples
| Stock Type | Pattern | Outcome |
|---|---|---|
| Penny stocks | ₹2 → ₹20 → ₹0.50 | 97% loss |
| SME IPOs | Listed at 2x, then crashed | 80% loss |
| Telegram tips | Up 100%, then down 90% | Retail trapped |
The Cooperative Bank Fraud: PMC Bank (2019)
Not Stocks, But Related
Punjab and Maharashtra Cooperative Bank collapsed due to massive fraud involving HDIL (Housing Development and Infrastructure Limited).
The Connection to Stock Market
- PMC Bank gave 73% of its loans to ONE company: HDIL
- HDIL stock was once a market darling
- When HDIL defaulted, PMC collapsed
- 16 lakh depositors affected, many lost life savings
Lesson
Red Flag: Don’t trust companies just because they’re listed. HDIL was a large-cap stock, yet it was fundamentally rotten.

- Fraud: Pledged client shares worth ₹2,000+ crores without consent
- How: Used clients’ demat holdings as collateral for own borrowings
- Outcome: SEBI banned Karvy, investor protection fund invoked
2. DHFL (2019)
- Fraud: ₹34,000 crore fraud through shell companies
- Impact: India’s largest corporate bankruptcy
- Lesson: Even “AAA-rated” companies can be fraudulent
3. Brightcom Group (2023)
- Fraud: Alleged fake revenue, shell companies
- Status: Stock crashed 75%, investigation ongoing

Before buying any stock:
- Read last 3 years’ annual reports

Never put more than 5% in any single stock. Even if one turns out to be a fraud, you lose only 5%.

- WhatsApp groups recommending stocks = Danger
- Telegram channels with “sure shot” tips = Scam
- YouTube/Instagram “educators” with buy calls = Questionable
Step 4: Check SEBI Actions
Visit sebi.gov.in periodically:
- Look up “Enforcement Orders”
- Check if any company you own is under scrutiny
Step 5: Use Only Registered Brokers
- Check broker registration on SEBI website
- Prefer large, established brokers
- Enable all account alerts
Step 6: Monitor Your Holdings
- Check consolidated account statement (CAS) monthly
- Verify all holdings are present
- Don’t share OTP/passwords
If You’re a Victim of Fraud
Immediate Steps
- Document Everything: Screenshots, communications, transactions
- File Complaint with SEBI: scores.gov.in
- File Police Complaint: Cyber crime or economic offences
- Contact Broker/Exchange: Investor grievance cell
- Consult Lawyer: For significant losses
Recovery Chances
Honestly, recovery is difficult. Prevention is far better than cure.
| Type of Fraud | Recovery Probability |
|---|---|
| Broker fraud | Moderate (investor protection fund) |
| Company fraud | Low |
| Pump and dump | Very low |
| Ponzi schemes | Near zero |
