why are stocks valuable?

Why Are Stocks?

Stocks are claims on a company’s future profits and assets. If you’ve asked “why are stocks” priced the way they are, this guide explains the mechanics: why people buy and sell shares, how prices are set in markets, and why stock prices move over time. You’ll get clear definitions, the major drivers of price action, examples from recent market episodes (including reporting as of December 30, 2025), and practical implications for investors.

Definition and purpose

A stock (also called equity or a share) represents fractional ownership in a corporation. When you own one share, you own a small portion of that company's economic claims — a right to a share of future profits (after obligations to creditors), and usually a vote in shareholder matters for common stock.

Why companies issue stocks

• Capital raising: Firms issue shares to raise money for growth, acquisitions, R&D, or to refinance debt without immediately increasing interest obligations. Equity complements other funding sources like loans or bond issuance.
• Risk sharing: Selling equity shares distributes business risk among many owners rather than concentrating it with founders or a single investor.

Common investor goals

• Capital appreciation: Many investors buy stocks expecting the company’s value and earnings to grow over time.
• Income: Some stocks pay dividends, offering a return stream from current profits.
• Diversification and strategy: Stocks are used in portfolios to access growth, hedge other exposures, or implement thematic bets (e.g., AI, automation).

How stock prices are determined

At the simplest level, stock prices are the outcome of trades: the last price is the point where a buyer and seller agreed. But multiple forces shape the supply/demand balance behind those trades. Below we break down the major drivers.

Supply and demand (market mechanics)

Market prices move when buy and sell interest changes. Key concepts:

• Order books and trade execution: On an exchange or trading venue, limit orders (orders placed at a specified price) and market orders (execute immediately at best available price) populate an order book. If buyers aggressively submit market buys, they consume available sell orders and push the last trade price higher; the reverse holds for aggressive selling.
• Liquidity: Liquidity is the ease with which shares can be bought or sold without moving the price much. Highly liquid stocks (large-cap, high average daily volume) generally have tighter spreads and smaller price moves for a given trade. Low-liquidity stocks can gap widely when a large order hits the market.
• Immediate pressure: Margin calls, large institutional reallocations, or block trades can create short-term imbalances that change the last-trade price quickly.

Fundamentals and valuation

Longer-term prices track investor expectations about a company’s future earnings and cash flows. Investors use frameworks such as:

• Earnings and cash flow forecasts: Higher expected future profits usually support higher valuations today.
• Multiples: Simple valuation tools like price-to-earnings (P/E) and price-to-sales (P/S) translate earnings or sales expectations into a price level.
• Discounted cash flows (DCF): This method estimates the present value of projected future cash flows using a discount rate; when expected growth or the discount rate changes, valuations shift.

Fundamental news that alters growth or profit expectations (new products, market share shifts, cost changes) can change intrinsic value estimates and thus affect price over time.

Macroeconomic and monetary factors

Economic growth, inflation, and central bank policy influence valuations across sectors:

• Growth expectations: Faster GDP growth raises expected corporate earnings across many companies, supporting higher equity prices.
• Inflation: High inflation can erode real earnings and increase costs; it may also push central banks to raise interest rates, tightening financial conditions.
• Interest rates and discounting: Lower interest rates reduce the discount rate used in valuation models, increasing the present value of future cash flows and often supporting higher stock prices. The inverse is true when rates rise.

Market sentiment and investor psychology

Sentiment — confidence or fear — often amplifies moves beyond what fundamentals alone would justify:

• Narratives and themes: Stories about new technology (e.g., AI), regulation, or demographic shifts attract capital and can bid up valuations in favored sectors.
• Herding and feedback loops: Rising prices attract more buyers (momentum), while declining prices can trigger selling (panic), causing exaggerated swings.
• Behavioral biases: Overconfidence, anchoring, and loss aversion shape individual and institutional decisions, affecting flow dynamics.

Technical factors and trading strategies

Short-term price action is often influenced by trading mechanics and strategies:

• Technical analysis: Price patterns, moving averages and support/resistance are used by traders to time entries/exits; large concentrations of stop orders can create cascades when levels are broken.
• Algorithmic and high-frequency trading: Fast traders can both provide liquidity and accentuate intraday moves when multiple algorithms respond simultaneously to the same signals.
• Leverage, margin and short positions: Leveraged long positions increase downside risk through forced liquidations; likewise, crowded short positions can lead to rapid short-covering spikes if prices rise.

Corporate events and news flow

Individual stocks respond strongly to firm-specific events:

• Earnings reports and guidance: Misses and upgrades often trigger sharp re-pricing.
• Dividends and buybacks: Dividend increases or share repurchases return capital to shareholders and often support prices; cuts or suspensions typically depress them.
• Mergers & acquisitions and management changes: These can materially change future profit trajectories or investor perceptions.
• Regulatory or legal developments: Fines, bans, or approvals can directly change a company’s outlook.

Structure and concentration effects

Indices and market headlines can be heavily influenced by a small number of very large companies. When a few firms dominate index weightings, their moves can sway headline performance even if the broader market is mixed. That concentration effect explains why indices sometimes diverge from median stock performance.

Why stocks tend to rise over the long term

Historically, broad equity markets have provided positive real returns over long horizons. Reasons include:

• Equity risk premium: Investors demand higher expected returns from stocks than from safer assets (like government bonds) to compensate for higher risk. That premium supports expected long-term returns above cash or bonds.
• Economic growth and compounding profits: As economies grow, companies generally increase revenues and earnings over time, and retained earnings invested back into businesses compound growth.
• Reinvestment and innovation: Firms reinvest profits into new products, productivity gains, and market expansion, generating higher future cash flows.
• Dividends and buybacks: Reinvested dividends and buybacks boost total returns and compound wealth.

These factors do not guarantee positive returns in every period — equities can decline sharply in the short and medium term — but they help explain the historical tendency for equities to rise over decades relative to lower-risk assets.

Causes of sharp declines, corrections and bubbles

Broad selloffs and sector-specific crashes can arise from multiple causes:

• Monetary tightening: Rapid rate hikes and shrinking liquidity can compress valuations and reduce access to cheap capital.
• Recession fears: Expected earnings declines during recessions lead to value contraction.
• Leverage unwinds: Forced liquidations (from margin calls or derivatives positions) can accelerate declines.
• Asset bubbles and speculative excess: When prices reflect unrealistic growth expectations rather than fundamentals, corrections occur as expectations reset.
• Policy or geopolitical shocks: Sudden regulatory changes, major legal rulings, or sanctions can trigger deep selloffs in affected sectors (note: this piece avoids political content but acknowledges regulatory shocks as price drivers).

Triggers for rapid unwinding are often technical: margin hikes, liquidity withdrawals, or unexpected negative news can convert gradual selling into sharp crashes.

Role of interest rates and Fed policy (focused discussion)

Interest rates and central-bank communication are powerful determinants of equity valuations:

• When the central bank cuts rates: Discount rates fall, borrowing costs decrease for businesses and consumers, and risk-free yields decline, often making equities relatively more attractive. In practice, rate cuts can lift risk asset prices and spur rotations into growth names.
• When the central bank raises rates: Higher discount rates reduce present valuations, borrowing costs increase, and consumption or investment can slow — pressuring earnings and valuations.
• Expectations matter: Markets respond not only to actual rate moves but to expectations and guidance. “Higher for longer” messaging can compress valuations even without additional hikes if investors re-price future cash flows accordingly.

Practical takeaway: rate cycles interact with earnings revisions, sectoral exposure (rate-sensitive sectors vs. defensive sectors), and liquidity — so stays in policy matter more than single decisions.

Valuation indicators and market “expensiveness”

Common metrics used to gauge market valuation include:

• Forward P/E: Price divided by estimated next-12-month earnings. A high forward P/E suggests investors expect higher growth or are paying a premium.
• Price-to-sales (P/S): Useful for early-stage or low-profitability firms; high P/S can signal speculative pricing.
• Buffett indicator: Total market capitalization divided by GDP — a macro-level gauge of market size vs. economic output.
• Cyclically Adjusted P/E (CAPE): Long-term inflation-adjusted earnings averaged over a cycle to smooth noise.
• Market breadth and sector valuations: Looking at median valuations, not just the market-cap-weighted average, helps spot concentration risk.

No single metric times markets perfectly; valuation indicators are signals for relative risk and margin of safety rather than definitive timing tools.

Practical implications for investors

Basic, practical rules derived from the drivers above:

• Diversification: Spread exposure across sectors, styles, and geographies to reduce single-company or theme risk.
• Time horizon alignment: Equities are better suited for investors with multi-year horizons who can weather short-term volatility.
• Risk tolerance and position sizing: Match allocations to how much drawdown you can psychologically and financially tolerate.
• Dollar-cost averaging: Regularly investing fixed amounts smooths entry prices over time.
• Rebalancing: Periodic rebalancing helps maintain target risk profiles and forces selling into strength and buying into weakness.
• Avoid market timing: Predicting short-term moves consistently is extremely difficult; strategies that rely on timing often underperform systematic approaches.

Common misconceptions

• “Market price = intrinsic value”: Not always. Market price is what buyers and sellers agree to at a point in time; intrinsic value is an analyst’s estimate based on fundamentals.
• “Low volatility = low risk”: Volatility measures price swings, but low volatility can mask liquidity risk or downside gaps; concentrated holdings or leverage can still produce large losses.
• “If fundamentals look good, price must rise immediately”: Markets price expectations, not momentary fundamentals. Good news may already be priced in, and sentiment or macro forces can dominate in the short term.
• “Historical returns guarantee future returns”: Past performance is informative but not determinative — regimes change, valuations re-price, and macro dynamics evolve.

Examples and recent market episodes

Below are case-study style summaries that illustrate several mechanisms discussed above. Each includes a reporting date to set the time context.

• Silver crash and leverage (price mechanics and forced liquidations): As of December 30, 2025, industry reporting showed a sudden silver decline of about 14% in just over an hour after CME margin hikes triggered forced liquidations, wiping out leveraged positions and amplifying the fall. Observers contrasted how similar mechanics have affected different assets, arguing that margin-driven moves can be indistinguishable across markets. Source: market news coverage (Dec 30, 2025).

• Bitcoin vs. silver debate (narratives and inconsistency in judgment): As of December 30, 2025, a tweet by finance commentator Shanaka Anslem Perera highlighted that Bitcoin’s earlier 30% correction and silver’s 14% crash were both driven by leverage and liquidations, raising questions about narrative-driven market commentary. This example shows how narrative and pre-existing opinions can color interpretations of identical market mechanics. Source: Crypto news roundup (Dec 30, 2025).

• Ethereum and macro tailwinds (macro and network fundamentals): As of December 30, 2025, reports noted that the U.S. dollar had fallen roughly 10% through 2025, and analysts at major firms expected dovish Fed policy into 2026. Ethereum traded near $2,955 in late December 2025 and showed technical compression that some analysts interpreted as accumulation. Token Terminal and CryptoQuant data indicated growing on-chain activity and falling exchange reserves (e.g., reported reserves down from ~20 million ETH to ~16 million ETH in 2025), suggesting holders were moving assets into staking or cold storage despite price weakness. Those dynamics illustrate how macro liquidity, dollar trends and network adoption can combine to influence asset demand and valuations. Source: market analysis and on-chain data reports (Dec 30, 2025).

• ServiceNow example (corporate fundamentals, acquisition reaction): As of December 30, 2025, software company ServiceNow showed a market capitalization around $161 billion with Q3 2025 revenue of $3.4 billion, and subscription revenue making up approximately $3.3 billion. The company announced a sizeable acquisition that led to a sharp one-day stock decline (~11%) as investors debated strategic fit and financing. This episode shows how acquisitions can create short-term volatility even in otherwise high-growth companies. Source: corporate Q3 filings and market reports (Dec 30, 2025).

Each episode underlines an important lesson: market moves often reflect a mix of technical, fundamental and sentiment drivers, and attribution can depend on which lens observers apply.

How this applies to retail vs. institutional investors

Access, objectives and constraints often differ across investor types:

• Retail investors:

  • Tools: Access trading platforms, ETFs, fractional shares and sometimes tokenized stocks that lower minimums.
  • Liquidity needs: Often more liquidity-constrained; may prefer ETFs or diversified funds.
  • Taxes and accounts: Typically simpler account structures, but tax impacts (capital gains, dividends) matter.
  • Strategies: Dollar-cost averaging, thematic ETFs, and long-term buy-and-hold are common.

• Institutional investors:

  • Tools: Advanced execution tools, algorithmic trading, dark pools, and bespoke research.
  • Constraints: Mandates, risk limits, regulatory and fiduciary duties can shape trading horizons.
  • Scale impact: Large orders can move markets, requiring execution tactics to minimize market impact.
  • Strategies: Active and passive strategies, risk-parity, hedging, and complex derivatives are routine.

Both groups benefit from clear custody and execution solutions. For retail investors seeking regulated exchange access and wallet custody, Bitget provides an integrated platform and Bitget Wallet to support trading and secure storage needs.
