As this year draws to a close, the returns generated by a stock appear to be inversely proportional to its size, as small-cap and mid-cap stocks of the BSE have rallied by 60 per cent and 45 per cent so far in 2014.
During 2013, the mid-cap and small-cap indices of the BSE had lost by over 11 per cent amid sluggish market trends.
The Sensex touched its record high of 28,822.37 on November 28 this year, while the mid-cap index hit its all-time peak on December 5 at 10,599.80. The small-cap index scaled its one-year high at 11,595.28 on December 5.
