What is a stock? Ownership, price, and why it moves - trading basics, chapter 1

How stock markets actually work - exchanges, bid/ask, and liquidity - trading basics, chapter 2
Behind every trade is an order book matching buyers to sellers. What an exchange really is, why the bid/ask spread is a hidden cost, how liquidity decides whether you get a fair fill, and what market hours change.

Position sizing and risk - the 1% rule that keeps you in the game - trading basics, chapter 7

R-multiple and expectancy - does your trading system actually make money? - trading basics, chapter 8
Win rate is the most over-rated number in trading. R-multiples measure every trade in units of risk, and expectancy tells you what you make per trade on average - the one number that decides if a system is worth running.

A History of Market Bubbles(10 chapters)
Ten bubbles, in order, from 1637 tulips to the AI supercycle. Each chapter is the evidence-first version, not the legend, and each one maps to the same four mechanics that keep repeating.
- 018 min read
Tulip Mania (1637): the first bubble, and why the famous version is mostly myth
In 1637 a single Dutch tulip bulb could change hands for the price of an Amsterdam canal house, then the market fell roughly 99% in a week. What actually happened is more useful than the legend.

South Sea Bubble (1720): the trade-riches story was a cover for a debt swap
South Sea shares ran from about 128 pounds in January 1720 to roughly 1,000 by August, then crashed to 100-200 by December. The real business was never trade. It was converting the national debt.
- 039 min read
Railway Mania (1845): the technology was real and the equity was still a bubble
In 1846 Parliament passed 272 railway acts and authorised capital near Britain's entire annual GDP. Most of those lines lost half their value or were never built. Real does not mean safe.

1929: the crash that gets blamed for the Depression it did not actually cause
The Dow ran from about 63 in 1921 to 381 in September 1929, then fell roughly 89% by 1932. The crash was real. The thing that turned it into a decade was the policy response, not the selloff.

Nifty Fifty (1972): the quality bubble, where the companies were great and the price was the mistake
In 1972 about fifty 'buy and never sell' growth stocks traded at 50 to 90x earnings, some above 100x. Then the 1973-74 bear market cut the S&P roughly 48% and many of them 60 to 90%. The companies were excellent. The price was the bubble.

Black Monday (1987): the worst day in Wall Street history that caused no depression
On 19 October 1987 the Dow fell 22.6% in a single day, the biggest one-day drop ever. No recession followed. The reason was code, and the response was a Fed that printed before lunch.

Dot-Com Bubble (2000): the internet was real, which is exactly why it was so dangerous
The Nasdaq ran from about 1,000 in 1996 to 5,048 in March 2000, then fell roughly 78% and erased about 5 trillion dollars. The trend was right. Picking the survivor was the hard part.
- 089 min read
2008: the bubble was not housing, it was leverage hidden inside complexity
The S&P 500 fell about 57% from its 2007 peak and Lehman filed the largest bankruptcy in US history. The shiny asset was houses. The real bubble was leverage, repriced AAA, and one model assumption.

The Everything Bubble (2021): the bubble was not in the meme stocks, it was in the price of money
GameStop hit roughly $483, Bitcoin roughly $69,000, ARKK and SPACs fell 67% or more in 2022, and bonds had their worst year in modern history. The single asset everyone missed was the one priced at zero: interest rates.

The AI Supercycle: is it a bubble? Why railways and dot-com already answered
Hyperscalers are spending hundreds of billions a year on AI compute while the dominant chipmaker helps finance its own customers. The history of bubbles says real technology and a real bubble are not opposites.
Foundations(8)
Standalone explainers on the methods behind the research: the concepts you need before the charts make sense.
What is short selling? Borrowing shares, unlimited risk, and short squeezes
Short selling means borrowing shares, selling them, and buying them back lower. The risk profile is inverted - gains cap at 100%, losses run unbounded - plus borrow fees and squeezes.
What is a moving average? SMA vs EMA, crossovers, and what they actually tell you
A moving average smooths price by averaging the last N closes, recalculated each bar. SMA vs EMA, the 20/50/200-day lengths, golden and death crosses, and why MAs lag instead of predict.
How to read an options chain - the columns that matter and the ones that trap you
An options chain looks like a wall of numbers; it's a structured table. What each column means (bid/ask, volume, open interest, IV, the Greeks), how to spot illiquid strikes, and how to pick an expiration and strike.
How to read an earnings report - results vs expectations, guidance, and the call
A stock reacts to earnings versus what was priced in, not to the raw numbers. How to read revenue/EPS against estimates, why guidance moves the stock more than the quarter, and why good prints still drop.
Dollar-cost averaging vs lump sum: the math, the psychology, and when each wins
DCA spreads a fixed dollar amount over time; lump sum invests it all at once. The honest math says lump sum wins on average - but DCA wins where it counts: risk, regret, and the way real income actually arrives.
What is walk-forward validation? 104 strategy-ticker pairs tested - only 54% survived
Walk-forward validation separates in-sample fluke from real edge. 104 (strategy, ticker) pairs tested on the QA universe - 56 ROBUST, 20 STABLE, 18 LUMPY, 10 no-trades. Here's the procedure, the verdicts, and why most retail backtests quietly fail it.
What is mean reversion? Three flavors backtested - and only one wins consistently
Mean reversion is a class, not a strategy. We walk-forwarded three implementations across 35 thematic names: regression-channel wins 22 of 35, Fibonacci basket wins at PF 1.76, flat-mean Bollinger wins 1 of 35. The structural reason is which mean you assume.
What is Fibonacci retracement? A quant's 3-year backtest on 48 live levels
Textbook Fibonacci is 23.6 / 38.2 / 50 / 61.8 / 78.6%. We backtested 48 user-curated levels across 12 themes - basket PF 1.76, Sharpe 1.42, +23.7% over 3 years. Here's what works, what doesn't, and on which name classes.
