what is correction in market and how to react to it ?

A correction in trading is when the price of a security drops by a meaningful amount in a relatively short period of time. Traders typically define a correction as a drop in value of 10% or more. This drop can happen over a few hours or a few days. Also, it can last for less than 24 hours or many months.

You can start by diversifying your portfolio. Spreading investments across different asset classes such as stocks, bonds, and commodities can help reduce risk and smooth out market volatility. A well-diversified portfolio is better positioned to withstand market corrections

A stock market correction describes a specific fall in value of at least 10% (but less than 20%) from a recent stock market high. Investors often use "stock market correction" to describe a drop in the market as a whole or within a specific index, like the S&P 500.
