I remember the 2008 blockbuster Ghajini for its famous ‘short-term memory loss’ dialogue than anything else. The same seems to be the case when it comes to stock markets, people forget fast, which is bad and good, depending on which side you sit or view the developments. In recent weeks a lot of speculation has gone into how Finance Minister Arun Jaitley will tax investments in equities. The concern looming mostly among market participants is about the lock-in period on equity investments.
