Hey, I’m behind Raan.
Harvard ’25. Been following tech stocks and dividend companies for 10+ years—reading filings, calls, reports, the usual.
This is where I dump my notes and thoughts on what I see. No advice. Just the raw stuff.
Introduction: What a Stock Price Really Means
Let’s get one thing straight:
A stock price is not the company.
It’s just the last price someone was willing to pay for a share.
That’s it.
It doesn’t tell you:
- How good the business is
- How profitable it is
- Whether it’s cheap or expensive
It only tells you one thing:
👉 What the market currently believes
Think of the stock price like a thermometer.
It measures temperature—it doesn’t explain why it’s hot or cold.
1. The Core Idea: Price = Perception
Stock prices are driven by perception, not reality.
Two key forces:
- Expectation of future earnings
- Investor sentiment
A company can be doing great, but if expectations were even higher:
👉 Stock falls
A company can be doing poorly, but if things look “less bad”:
👉 Stock rises
That’s the game.
2. Supply and Demand — The Real Engine
At the most basic level:
- More buyers than sellers → Price goes up
- More sellers than buyers → Price goes down
Simple.
But behind that simplicity lies:
- News
- Fear
- Greed
- Algorithms
- Institutional money
All pushing and pulling at the same time.
3. Intrinsic Value vs Market Price
This is where most confusion happens.
Market Price
What you see on your screen.
Intrinsic Value
What the business is actually worth (based on earnings, growth, etc.)
The gap between these two:
👉 That’s where opportunities (and risks) live.
4. Earnings: The Backbone of Price
Over time, stock prices follow earnings.
Not daily. Not weekly.
But over the years:
👉 Earnings drive price
Companies with:
- Strong revenue growth
- Expanding margins
- Consistent profits
…tend to see rising stock prices.
5. Multiples: Why Prices Look “High” or “Low”
Price alone means nothing.
A ₹10 stock isn’t “cheap.”
A ₹10,000 stock isn’t “expensive.”
You need context.
Common Metrics
- P/E Ratio (Price to Earnings)
- P/S Ratio (Price to Sales)
These tell you:
👉 How much are investors willing to pay for growth
6. Growth Expectations: The Hidden Driver
Stocks are forward-looking.
If investors believe:
- Growth will accelerate → Price rises
- Growth will slow → Price falls
Even if current earnings are strong.
This is why:
👉 High-growth companies often trade at high valuations
7. News and Stock Prices
News acts like a trigger.
Examples:
- Earnings reports
- Product launches
- Economic data
- Political events
But here’s the twist:
👉 Markets react to surprises, not news itself.
8. The Role of Institutions
Big players move prices:
- Mutual funds
- Hedge funds
- Pension funds
They control massive capital.
When they buy or sell:
👉 Prices move significantly
Retail investors?
👉 Mostly reacting, not driving.
9. Short-Term Price Movements
Short-term price action is chaotic.
Driven by:
- News
- Trading algorithms
- Market sentiment
It’s noisy.
Trying to predict it consistently?
👉 Extremely difficult.
10. Long-Term Price Movement
Zoom out.
Over time, stock prices reflect:
- Business growth
- Economic expansion
- Innovation
This is where clarity exists.
11. Volatility: Why Prices Swing
Volatility is normal.
Reasons include:
- Uncertainty
- Earnings surprises
- Macro events
Think of volatility like waves:
👉 The ocean (long-term trend) matters more than the waves.
12. Market Psychology: The Invisible Force
Stock prices are heavily influenced by human behavior.
Key emotions:
- Fear
- Greed
- Hope
- Panic
These create:
- Bubbles
- Crashes
- Overreactions
Understanding psychology is half the game.
13. The Role of Central Banks
Central banks influence stock prices indirectly.
Examples:
- Federal Reserve
- Reserve Bank of India
Impact:
- Lower interest rates → Stocks rise
- Higher rates → Stocks struggle
Liquidity matters.
14. Inflation and Stock Prices
Inflation affects:
- Consumer spending
- Corporate margins
- Interest rates
Moderate inflation → okay
High inflation → negative for stocks
15. Interest Rates: The Silent Killer
Interest rates are critical.
When rates rise:
- Borrowing becomes expensive
- Valuations compress
Especially for:
👉 Growth stocks
16. Sector Rotation
Money moves between sectors.
Example:
- Tech → Defensive
- Growth → Value
This causes:
👉 Price changes even without company-specific news
17. Dividends and Price Behavior
Dividend-paying stocks behave differently.
They:
- Provide income
- Are less volatile
Price growth may be slower—but steadier.
18. Market Cycles and Price Trends
Every stock goes through cycles:
- Growth phase
- Peak
- Decline
- Recovery
Recognizing cycles helps avoid extremes.
19. Common Misconceptions About Stock Price
1. Low price = cheap
False.
2. High price = expensive
Also false.
3. Price always reflects reality
Not always.
Markets can be irrational.
20. What Actually Moves Stock Prices (In One Line)
If you had to summarize everything:
👉 Stock price = Future expectations × Investor sentiment
That’s the formula.
21. Real Example Insight
Looking at the chart above (Apple stock):
You can observe:
- Short-term fluctuations
- Longer-term upward trend
- Periods of consolidation
This is typical:
👉 Volatility in the short term
👉 Growth over the long term
22. Why Timing the Market Is Hard
Because:
- News is unpredictable
- Sentiment changes quickly
- Prices react instantly
Even professionals struggle with timing.
23. The Role of Liquidity
Liquidity = money in the system.
More liquidity:
👉 Higher stock prices
Less liquidity:
👉 Pressure on markets
24. Risk and Stock Prices
Risk affects valuation.
Higher risk → Lower price
Lower risk → Higher price
Risk includes:
- Business risk
- Economic risk
- Regulatory risk
25. Final Thought: Price vs Value
Here’s the key distinction:
- Price is what you pay
- Value is what you get
Markets often confuse the two.
Your job (if you’re thinking deeply) is to separate them.
Conclusion
Stock prices look simple on the surface—just numbers going up and down.
But underneath?
They represent:
- Human behavior
- Economic forces
- Business performance
- Future expectations
It’s not just math.
It’s psychology + economics + time.
And once you understand that, you stop reacting to price—and start interpreting it.
