in an attempt to break the cycle of fear and selling. Shorting investment strategy that speculates on the decline
of a stock's price. The investor borrows shares of a stock from a lender and instantly sells them. When it's time to
give them back, the investor has to buy back the shares to reive them to the lender. If the price has gone down, he
keeps the difference between the initial price and the new price. This, however, comes with unlimited risk as the stock
price can go up infinitely and the investor is forced to buy it back. Short squeeze. When the stock's price

it. Limit order. It's an order to buy or sell a stock at a specific price or better. Stop-loss order. Order placed to

investing. It's a trading strategy that involves picking stocks that appear to be trading for less than their intrinsic
or book value. Value investors usually believe that the market overreacts to good and bad news and buy stocks that
they think the market is underestimating. Growth investing. Growth investors typically invest in
young and small companies whose earnings are expected to increase at an above average rate compared to the market.

from its revenue after subtracting all of its costs. Dollar cost averaging. It's a strategy that consists of
investing a fixed amount of money at regular intervals regardless of the asset's price. This helps reduce the
impact of market volatility. Return on investment.
A bull market is characterized by rising prices, often leading to strategies like 'going long' (buying low and selling high), while a bear market involves falling prices, where traders may use shorting or defensive tactics like stop-loss orders. The names derive from the animals' attacking styles—bulls thrust upward, bears swipe downward—reflecting market direction. Understanding these conditions helps you adjust your approach, such as favoring growth stocks in bull markets or value investing during bear phases.
A market order executes immediately at the best available price, guaranteeing a trade but not the price—ideal for urgent moves. A limit order sets a specific price or better, ensuring cost control but risking non-execution, useful for planned entries/exits. A stop-loss order triggers a market sale when a stock hits a preset price, acting as a risk management tool to limit losses automatically during sharp declines.
The P/E ratio (Price-to-Earnings) compares a stock's current price to its earnings per share, helping investors gauge if a stock is overvalued (high P/E) or undervalued (low P/E) relative to peers or historical averages. However, it relies on past earnings and does not guarantee future performance, so it should be used alongside metrics like price-to-book ratio or EPS. A high P/E might indicate growth expectations, while a low P/E could signal a value opportunity.
Shorting involves borrowing shares to sell them, hoping to buy them back at a lower price for a profit. If the price rises instead, you must cover at a loss, with theoretically unlimited risk since stocks can climb indefinitely. Beginners should avoid shorting until they master risk management, as it requires precise timing and can lead to margin calls or significant losses in volatile markets.
Mutual funds pool money from many investors for professional management but often have higher fees and trade at day-end prices. ETFs (Exchange-Traded Funds) track baskets of stocks like index funds but trade like regular stocks throughout the day with lower expense ratios. Index funds are a type of ETF or mutual fund that replicate a market index (e.g., S&P 500), offering broad diversification and low costs, ideal for beginners focusing on long-term growth.
Dollar cost averaging involves investing a fixed amount regularly regardless of price, buying more shares when prices are low and fewer when high, which smooths out volatility over time. It reduces the risk of mistiming the market compared to lump-sum investing, though lump-sum may yield higher returns in strong bull markets. For beginners, it builds discipline and emotional control, making it a safer starting strategy.
A pump and dump involves artificially inflating a stock's price through false hype to sell at a profit, often targeting penny stocks or cryptocurrencies (a rugpull). To protect yourself, verify company fundamentals, avoid unsolicited tips on social media, and stick to reputable exchanges. Recognizing red flags like sudden price surges without news or limited liquidity helps avoid these fraudulent schemes.
