What is growth investing
Growth investors buy stock that has a history of growth, has good managemnt, there is expectation of continuing growth, etc.
Even stocks that have historical growth can continue to grow,
When Warren Buffett bought $1bn of Coca Cola stock in 1988 its shares had already grown fivefold in the previous six years and five hundredfold in the previous sixty years. That didn't stop it quadrupling in the next three.
Value investing is very different. Value investors buy based on price. The cheaper the stock vs the net value of the company, the better the deal. It is a quantitative decision rather than a qualitative decision made by growth investors.
Value investors will sell their stock when the price goes down, growth investors will sell based on the trends, ability of future earnings, management capabilities, etc.
Growth investors rely a lot on their own instinct and personal knowledge and skills.
