WTF Is a Stock?

When a company wants to raise money, they can sell little pieces of ownership in themselves. Each piece is called a share, and you can buy them. When you own a share, you own a tiny sliver of that company.

๐ŸŒ Real Example Right Now
Apple (AAPL) has about 14.69 billion shares outstanding.
Right now, each share costs $308.82.
So Apple's total value = $308.82 ร— 14.69B shares = $4.54 Trillion.
When you buy 1 share of AAPL, you own 1/14,687,356,000 of Apple Inc.
๐Ÿ’ก TL;DR: A stock = a tiny ownership stake. When the company does well, your stake is worth more. When it tanks, you lose money.
02

Buying vs. Selling โ€” Simple

๐Ÿ“ˆ Buying (Going Long)

You buy shares because you think the price will go up. You profit if you sell later at a higher price.

You buy 10 shares of NVDA at $215.33. If it goes to $258.40, you made 20%.
๐Ÿ“‰ Selling (Closing Position)

You sell shares you already own, cashing out your profit (or cutting your loss). You never have to wait for a stock to go back up.

Cut your losses early. A 50% drop requires a 100% gain just to break even.
๐Ÿ’ก TL;DR: Buy low, sell high. Sounds obvious โ€” most people do the opposite because emotions take over.

How to Read a Chart

Stock charts look scary but they're just price over time. Here are the only things you need to understand:

๐Ÿ•ฏ๏ธ
Candlestick
Each candle = one time period (1 hour, 1 day, etc.). Green = price went up. Red = price went down.
๐Ÿ“Š
Volume
The bars at the bottom. High volume = lots of people buying/selling. A price move on high volume is more reliable.
๐Ÿ›ก๏ธ
Support
A price level where the stock keeps "bouncing." Think of it as a floor. Stocks often bounce off support.
๐Ÿšง
Resistance
A price level the stock keeps failing to break through. Think ceiling. When it finally breaks โ€” big move.
๐Ÿ“ˆ
Trend
Is the stock making higher highs and higher lows? That's an uptrend. Lower lows? Downtrend. Trade with the trend.
ใ€ฐ๏ธ
Moving Average
A smoothed line showing the average price over N days. Price above MA = bullish. Price below = bearish.
๐Ÿ’ก TL;DR: Green candle = price went up that day. Red = down. Volume tells you how many people cared. Lines show trends.
05

The P/E Ratio โ€” Explained Like You're 5

The P/E ratio asks: "How much are investors paying for every $1 this company earns?"

๐Ÿ• Imagine a pizza shop earns $10,000 per year. If someone offers to buy the whole pizza shop for $100,000, the P/E would be 10 (they're paying 10x earnings). Is that fair? Depends on how fast the pizza shop is growing.

๐ŸŒ Live Examples Right Now
NVDA 33.0x P/E ๐Ÿ”ถ High โ€” priced for big growth expectations
AAPL 37.4x P/E ๐Ÿ”ถ High โ€” priced for big growth expectations
GME 28.5x P/E ๐ŸŸก Fair โ€” priced for moderate growth
๐Ÿ’ก TL;DR: Low P/E = cheap (maybe). High P/E = expensive (maybe). Context matters โ€” a 100x P/E is fine for a company growing 80% per year.
07

Short Selling & Short Squeezes

Short selling is when you bet a stock will go down. You borrow shares, sell them, and hope to buy them back cheaper later. But it can blow up in your face.

๐Ÿฉณ The Short Trade
  1. Borrow 100 shares of GME at $20
  2. Sell them immediately for $2,000
  3. Stock drops to $10 โ€” you buy 100 shares back for $1,000
  4. Return the shares. Profit: $1,000 ๐Ÿ’ฐ
๐Ÿ’ฅ The Short Squeeze

If the stock rises instead of falling, shorts must buy back at higher prices to cover. This buying pressure causes the stock to spike even more โ€” the famous "short squeeze."

GME (currently $21.96) went from ~$4 to $500 in Jan 2021 when WSB squeezed the shorts.
๐Ÿ’ก TL;DR: Shorting = betting a stock falls. Risk is theoretically unlimited (stock can go to infinity). Only for experienced traders.
08

RSI & Moving Averages โ€” What They Actually Mean

RSI 70-100: ๐Ÿ”ด Overbought โ€” stock may be due for a pullback
RSI 30-70: ๐ŸŸก Normal trading range
RSI 0-30: ๐ŸŸข Oversold โ€” potential buying opportunity

RSI measures momentum on a scale of 0-100. Think of it as a speedometer for price moves. If it's going too fast up (>70), it often slows down. Too far down (<30), it often bounces.

Moving Averages (MA) smooth out the price noise. The 200-day MA is the most important one. If the price is above it, you're in bull territory. Below it โ€” bear territory. Institutions use this line religiously.

๐ŸŒ Live Example: NVDA
NVDA is currently trading at $215.33 โ€” check its stock page to see its RSI, 20-day MA, 50-day MA, and 200-day MA in real-time.

๐Ÿ’ก TL;DR: RSI above 70 = overheated. RSI below 30 = oversold. Price above 200-day MA = probably trending up.
09

Meme Stocks & WallStreetBets

Meme stocks are stocks that go viral on social media (especially Reddit's r/wallstreetbets) and get pumped by retail traders โ€” often ignoring fundamentals entirely.

โœ… When Meme Stocks Work
  • High short interest (shorts get squeezed)
  • Low float (small supply = big price moves)
  • Genuine viral momentum on WSB
  • You get in EARLY โ€” before the peak
โŒ When They Wreck You
  • You buy after it's already up 500%
  • You ignore the fundamentals (company might be bankrupt)
  • You hold the bag when whales dump
  • You use margin (leverage) on volatile plays
๐ŸŽฎ GME Today
GameStop (GME) โ€” the original meme stock โ€” currently trades at $21.96, โ–ผ 2.36% today. It hit $483 during the Jan 2021 squeeze. Now it just kind of sits there. Most people who bought the top are still underwater.
๐Ÿ’ก TL;DR: Meme stocks are real plays โ€” but timing is everything. If you're seeing it on the news, you're already late.

Penny Stock Risks โ€” Read This Before You YOLO

โ˜ ๏ธ
Penny stocks kill portfolios.
Most penny stocks (stocks under $5) are there for a reason โ€” the company is burning money, diluting shareholders, or outright fraudulent. The majority eventually go to zero.
๐Ÿ’€
Dilution
Companies issue millions of new shares to raise cash. Your shares get worth less. This is the #1 way penny stocks kill you.
๐Ÿ“ฃ
Pump & Dump
Promoters buy shares, hype the stock on social media, then dump at the top leaving retail investors holding the bag.
๐Ÿ’ธ
Wide Spreads
The buy price (ask) and sell price (bid) can be 5-20% apart. You lose money the moment you buy.
๐Ÿ”’
Low Liquidity
You might not be able to sell when you want to. If the stock crashes, you're stuck watching it go to zero.
๐Ÿ’ก TL;DR: If you're going to trade penny stocks, keep position sizes tiny, set hard stops, and never average down. They are lottery tickets โ€” most expire worthless.

The Actual Rules for Not Losing Money

01
Never invest money you can't afford to lose
This is not a clichรฉ. The market can drop 50% and stay there for 2 years. Only invest what won't change your life if it disappears.
02
Don't use margin until you're experienced
Margin = borrowing money to invest more. It amplifies gains AND losses. Beginners regularly blow up their entire account in a day using margin.
03
Set stop losses and actually follow them
Decide before you buy: "I will sell if this drops X%." Then do it. The biggest losses come from holding and hoping while a stock melts down.
04
Don't FOMO in at the top
When a stock is all over your news feed, you've already missed most of the move. The people profiting are selling to the people FOMOing in.
05
Diversify โ€” don't put it all in one stock
Even the best analysts are wrong. Spread across multiple positions so one bad pick doesn't wipe you out.
06
Know your timeframe
Are you day trading? Swing trading? Long-term investing? Each requires totally different strategies. Most beginners mix them up and lose.
