Beating the Index is Harder Than It Looks
Beating the stock market index is really hard.
The index is like a big basket of stocks, and it's designed to include the best-performing ones automatically.
Most individual stocks don't do as well as the index because a few big winners pull the index up.
Over the years, only about 45% of stocks beat the index.
Even if you hold stocks for three years, it's still tough to do better than the index.
The top-performing stocks can return many times more than the index, but it's hard to pick them in advance.
Also, the index keeps updating itself by adding new successful companies and removing those that don't do well.
This makes it even harder for individual investors to beat the index consistently.
So, while it's possible to beat the index, it's much harder than it seems.
The Nifty 500 index is hard to beat because it's cap-weighted, meaning a few top performers drag the whole index up.
Only about 45% of stocks in the index beat it in a typical year, and this drops to 42% over three years.
The top 10-20 performing stocks generate most of the wealth, with returns 5-10 times higher than the index over three years.
Winners don't persist; only about 47% of stocks that beat the index in one period continue to do so in the next.
The index automatically updates by adding successful companies and removing underperformers, making it a formidable adversary.
