Bear Market
A bear market is a prolonged period when stock prices fall 20% or more from recent highs, usually accompanied by widespread pessimism. India has experienced bear markets in 2000 (dotcom), 2008 (global financial crisis), and 2020 (COVID). Bear markets are buying opportunities for long-term investors.
During COVID crash in March 2020, Nifty fell 38% from 12,400 to 7,511. Investors who bought at the bottom saw 100%+ returns in the next 2 years.
Blue Chip Stocks
Blue chip stocks are shares of well-established, financially stable, large-cap companies with a long track record of reliable earnings and dividends. In India, examples include Reliance, TCS, HDFC Bank, Infosys, and ITC.
Investing ₹1 lakh in HDFC Bank shares 10 years ago would be worth approximately ₹3-4 lakh today, demonstrating the steady growth blue chips offer.
Bull Market
A bull market is a prolonged period of rising stock prices (typically 20% or more from recent lows), accompanied by optimism and strong investor confidence. India's longest bull run was from 2003-2008 and 2020-2024. Bull markets often end with euphoria and overvaluation.
Nifty rose from 7,511 in March 2020 to 26,000+ by September 2024 — a massive 245% bull run driven by liquidity and post-COVID recovery.
CDSL (Central Depository Services)
CDSL is India's second securities depository, established in 1999, promoted by BSE. It holds securities in electronic form. CDSL accounts start with '12' prefix. As of 2025, CDSL has more demat accounts than NSDL due to the rise of discount brokers like Zerodha which use CDSL.
Most discount broker accounts (Zerodha, Groww, Upstox) are with CDSL, while traditional brokers (ICICI Direct, HDFC Securities) often use NSDL.
Equity (Shares)
Equity represents ownership in a company through shares. When you buy equity shares, you become a part-owner of the company. Equity investments carry higher risk than debt but offer higher long-term returns (12-15% historically for Indian equities). Types: large cap, mid cap, small cap.
Buying 10 shares of TCS at ₹3,500 means you own a tiny fraction of TCS — if TCS profits grow, your share value and dividends increase.
Face Value (Par Value)
Face value is the original value of a share as stated in the company's charter. Most Indian companies have a face value of ₹1, ₹2, ₹5, or ₹10 per share. Face value is different from market price and is used for dividend calculation, stock splits, and bonus issues.
If a company with ₹10 face value does a 1:1 stock split, the face value becomes ₹5, number of shares doubles, but your total investment value stays the same.
Futures Contract
A futures contract is a standardized agreement to buy or sell an asset at a predetermined price on a specific future date. In India, equity futures trade on NSE/BSE with lot sizes. Futures require margin money (typically 15-25% of contract value) and settle on expiry date.
Buying 1 lot of Nifty futures (50 units) at 22,000 with margin of ₹1.5 lakh. If Nifty goes to 22,500, profit = 50 × 500 = ₹25,000 (16.7% return on margin).
Large Cap Stocks/Funds
Large cap companies have market capitalization above ₹20,000 crore (top 100 by market cap as per SEBI). They are well-established, financially stable, and less volatile. Large cap mutual funds must invest at least 80% in large cap stocks. Suitable for conservative equity investors.
Reliance, TCS, HDFC Bank are large cap stocks. A Nifty 50 Index Fund is essentially a large cap fund with very low expense ratio.
Margin Trading
Margin trading is borrowing money from a broker to buy securities, using your existing securities or cash as collateral. It amplifies both gains and losses. SEBI requires minimum margin of 20% for equity. Margin call occurs when your margin falls below minimum, requiring additional funds.
With ₹1 lakh and 5x leverage, you can buy shares worth ₹5 lakh. If the stock rises 10%, you profit ₹50,000 (50% return). But a 10% drop means ₹50,000 loss.
Market Capitalization
Market capitalization (market cap) is the total market value of a company's outstanding shares, calculated by multiplying the current share price by total number of shares. Companies are classified as Large Cap (>₹20,000 Cr), Mid Cap (₹5,000-20,000 Cr), and Small Cap (<₹5,000 Cr).
If Reliance has 676 crore shares at ₹2,500 each, its market cap is ₹16.9 lakh crore, making it India's most valuable company.
Market Correction
A correction is a decline of 10-20% in stock prices from recent highs. It is a normal and healthy part of market cycles. Corrections differ from bear markets (20%+ decline) and crashes (sudden sharp decline). They present buying opportunities for disciplined investors.
Nifty falling from 26,000 to 23,000 (11.5% decline) is a correction — not a crash. Use this as opportunity to increase your SIP amount or invest lump sum.
Mid Cap Stocks/Funds
Mid cap companies rank 101st to 250th by market capitalization (₹5,000-20,000 crore range as per SEBI). They offer higher growth potential than large caps but with more volatility. Mid cap funds must invest 65%+ in mid cap stocks. Good for long-term aggressive investors.
Companies like Voltas, Persistent Systems, and PI Industries are mid caps — they can potentially become large caps over time, offering multi-bagger returns.
Nifty 50
Nifty 50 is the benchmark stock market index of the National Stock Exchange (NSE) comprising 50 of India's largest and most liquid companies across 13 sectors. It is maintained by NSE Indices Limited (formerly India Index Services & Products Limited).
If Nifty 50 moves from 22,000 to 23,100, it means the index gained 5%, indicating overall market sentiment is positive.
NSE (National Stock Exchange)
NSE is India's largest stock exchange by trading volume, established in 1992 and headquartered in Mumbai. It introduced electronic screen-based trading in India. Its key indices are Nifty 50 and Nifty Bank. NSE has over 2,000 listed companies.
When you place a buy order for Infosys shares on Zerodha, the trade is executed on the NSE platform, matched with a seller's order electronically.
Options Trading
Options are derivative contracts that give the buyer the right (but not obligation) to buy (Call) or sell (Put) an underlying asset at a specified price before/on expiry. Option buyer pays a premium; seller receives it. India is the world's largest options market by volume.
Buying a Nifty 22,000 Call option for ₹200 premium (1 lot = 50 units, cost ₹10,000). If Nifty expires at 22,500, profit = (500-200) × 50 = ₹15,000.
P/E Ratio (Price to Earnings)
P/E ratio measures how much investors are willing to pay for each rupee of a company's earnings. It is calculated by dividing the current share price by earnings per share (EPS). A higher P/E indicates investors expect higher growth. Nifty 50 average P/E is typically 20-25.
If TCS shares trade at ₹3,500 and EPS is ₹100, the P/E ratio is 35x — meaning investors pay ₹35 for every ₹1 of TCS earnings.
Stock Split
A stock split is a corporate action where a company divides its existing shares into multiple shares, reducing the face value proportionally. A 1:1 split doubles the number of shares at half the face value. The total investment value remains unchanged but improves affordability and liquidity.
If Reliance does a 1:5 split, one ₹2,500 share becomes 5 shares of ₹500 each — you still own the same value, but more shares.
Stop Loss Order
A stop loss is an order placed with a broker to buy or sell a stock when it reaches a specified price, limiting potential losses. It is essential for risk management, especially in intraday and futures trading. Stop loss can be a fixed price or trailing (moves with the stock price).
You buy a stock at ₹200 and set a stop loss at ₹185 — if the price drops to ₹185, it automatically sells, limiting your loss to ₹15 per share (7.5%).
