Stocks that have significantly increased in price due a large demand are called overbought. This is often the case when there are too many buyers who push the price so high that it can’t be justified by company financials. When sellers start outweighing buyers, the price can change its direction. Another scenario that causes stocks to become overbought is when a company buys back its own stocks. Be careful when buying overvalued stocks as there could be a retracement.
