Quantitative Investing Kya Hota Hai?

Quantitative investing ek aisa tarika hai jisme financial decisions purely mathematical models, statistical analysis aur historical data ke basis pe liye jaate hain. Yahan koi gut feeling nahi chalti. Koi bhi trade ek defined rule set ke against validate hoti hai.

Sochiye ek doctor ko. Woh bimari diagnose karne ke liye symptoms, test results aur historical data use karta hai, sirf andaaze pe nahi chalta. Quant investing exactly aise hi kaam karta hai. Har investment decision ke peeche ek measurable, testable hypothesis hoti hai.

India mein retail investors generally tip-based ya news-based decisions lete hain. Quant approach seedha ulta hai. Pehle data, phir decision.

Pehla pillar hai Data. Historical prices, volumes, financial statements, macroeconomic indicators, aur aajkal alternative data jaise satellite images ya credit card transactions. Data jitna zyada aur clean, model utna better.

Doosra pillar hai Model. Ek mathematical framework jo data ke patterns dhundta hai. Yeh simple ho sakta hai jaise 200-day moving average crossover, ya complex jaise machine learning-based multi-factor model.

Teesra pillar hai Execution. Model ne signal diya, ab trade efficiently execute karna. Slippage, brokerage costs, aur market impact ko minimize karna. Indian markets mein transaction costs kaafi matter karte hain especially F&O mein STT ki wajah se.

Discretionary investor apni judgment, experience aur analysis use karta hai. Quant investor ek pre-defined system follow karta hai jo backtested hota hai. Dono ke apne advantages hain.

Discretionary investing mein flexibility hoti hai. Agar market mein koi unprecedented event ho jaise COVID lockdown, toh experienced investor apna view quickly adjust kar sakta hai. Lekin emotional biases bhi aa jaati hain. Loss pe hold karna, profit pe jaldi exit karna.

Quant investing consistent hoti hai. System same rule follow karega chahe market upar jaye ya neeche. Lekin agar model incomplete hai ya data poor quality ka hai, toh system blindly galat decisions leta rahega. Isliye model validation bahut zaroori hai.
