The screener that identifies stocks with the highest increase in promoter shareholding  showed something interesting when the September data was released: eight of the top ten stocks with the highest promoter increases were PSU banks, including Andhra Bank, UCO Bank, and IDBI Bank. 12 of the top 25 stocks in the screener were also PSU banks, with the government being the promoter rapidly increasing its shares in these stocks. 

Now that the bank recapitalization policy was announced yesterday, these stocks have been soaring, gaining in share price in the high double digits. But this screener had already made it clear weeks ago that action was coming from the government to rescue PSU banks struggling under high levels of NPAs. And the government obviously felt that this move would stabilize banking stocks and help them recover.
