What are support and resistance of a stock?
Support and resistance points indicate price levels where there have been a large amount of trading activity, usually from institutions, that tend to stabilize the price of a stock. Support is a temporary FLOOR, where people have been buying in large quantities. That means there's a good chance that the stock won't go below this level in the near term. (But if it does, watch out.) Resistance is a temporary CEILING where people have been selling. When the stock price hits this level, people tend to sell, and push it back down. Until there are "no more" sellers at this level. Then the price could skyrocket if there is enough buying.
