Grow. Amplified.
A point-to-point return is one draw from a distribution, and the draw is chosen by the start date. What rolling returns measure instead, how to read the spread, and why the median matters more than the headline.
Each criterion added to a screen improves how it looks on the data you built it on and usually worsens how it performs on data you did not. Why that happens, and how to tell fit from edge.
Generating test cases from a written requirement works well until the requirement is ambiguous, which is most of the time. What the model does with the gaps, and how to structure the work so it surfaces them instead of filling them.
Holding more funds spreads the fee, not necessarily the risk. How to compute what you actually own at the stock level, why the top holdings dominate, and what a genuine reduction in concentration looks like.
Opt-in, the 24-hour window and template approval decide what you can send on WhatsApp, not your CRM. What each rule means, why TRAI's DLT registration does not apply, and how a contact list shrinks to a reachable audience.
AI generates tests quickly, but generated tests assert current behaviour, which encodes existing bugs as expected. Where AI genuinely reduces QA effort, where the oracle problem stops it, and how to tell the two apart.
Agents are chosen for task complexity when the deciding factor is input variance. Where each one belongs, why an agent's failures are harder to catch than a script's, and the hybrid that usually wins.
Survivorship bias, look-ahead bias and overfitting each inflate backtested returns in ways that vanish in live trading. What each one is, how it creeps in, and how to test for it.
Most screens return either four companies or four hundred. How to choose criteria that narrow a universe without accidentally encoding a single sector, and how to sanity-check a screen before trusting it.
Zero-brokerage is not zero-cost. A full breakdown of every charge on an Indian equity trade, why slippage usually exceeds the visible fees, and what it does to a high-frequency strategy.
Holding five funds does not mean holding five portfolios. How to compute overlap between funds, what counts as high, and why diversification by fund count is a poor proxy for diversification.
CAGR and XIRR answer different questions, and using the wrong one can overstate a SIP return by several percentage points. The formulas, a worked example, and when each applies.
