The study looked at whether companies buying back their own shares helps make stock prices more accurate. They analyzed data from 337 US companies from 2012 to 2016. The results showed that when companies buy back more shares, stock prices become more efficient by quickly reflecting new information. This suggests that share repurchases can signal good news to investors and support stock prices. The findings suggest that share buybacks can help reduce panic selling, attract more informed traders, and draw attention to undervalued stocks. This research challenges the idea that companies use share repurchases to manipulate their stock prices.
