This impressive surge came after huge losses suffered by the medium and small stocks last year, benefiting from the revival in investor sentiments since a new government took over in May 2014. Experts say that small-caps and mid-caps do better than large-caps in a rising market, but their losses are also larger when the markets fall.
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 percent and 45 percent so far in 2014.
In comparison, the blue-chip stock index has gained just about 25 percent in the same period.
During 2013, the mid-cap and small-cap indices of the BSE had lost by over 11 percent 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.
"With a buoyant outlook perceivable for the Indian markets, depreciating oil prices and controlled modest inflation, small-caps have risen up to the mark showcasing a dynamic movement... ," said Yogesh Nagaonkar, Vice President Institutional Equities, Bonanza Portfolio.
This performance has come on the back of higher participation from investors realising the potential benefits at hand of these companies, which can utilise the favourable factors to perpetuate higher earnings growth, he said.
"A large-cap stock is going to be better priced than a mid-cap stock, and a mid-cap will be better priced than a small-cap. Therefore, when overall markets are going up, the small-cap stock is more prone to be price sensitive than a large-cap," said Raghu Kumar, Cofounder, RKSV.
Marketmen said that small and mid-caps suffer the most during times of uncertainty and crisis due to weaker balance sheets, which reflects in their stock prices as well.
Bullish investor sentiment following a new government at the Centre and robust foreign fund inflows have helped the rally in the domestic equity markets, they added.
"Markets did extremely well in 2014 due to a new government coming into power in May and unleashing an array of reforms aimed at garnering economic growth.
"Additionally, macro economics has been fundamentally sound in 2014, with a growing GDP, low inflation, and a high influx of FII investment flows. These all add up to a surge in market prices in blue-chip stocks, the foundation of the Indian economy," Kumar said.
Foreign investors have pumped in over Rs 1 lakh crore in the Indian stock market this year, taking their cumulative investment to more than Rs 10 lakh crore.
Since May 16, when the general election results were announced the key index Sensex has gained nearly 11 percent.
Retail investors are major participants in mid-cap and small-cap stocks and their activity in this segment has been upbeat over the past few months.
Market players say smaller stocks are generally bought by local investors, while overseas investors focus on blue-chip shares.
The mid-cap index tracks companies with a market value that is on an average one-fifth of blue-chips or large firms. Small-cap firms are almost a tenth of that.
"Now as the market sentiment is changing from negative to positive, these stocks are playing the catch up. With improvement in stock market, many mid-cap and small-cap companies with high debts are being able to raise money from the market to lower their debt," Nagaonkar said.
On the outlook for these sectors in the new year, Kumar said, "There is a strong correlation between small/mid-caps and the overall economy. Since we are in the middle of a bull run where markets are expected to perform well over the next few years, we can definitely expect small and mid-caps to take advantage of the bull run.
"Investors will also look to diversify their portfolio by including small and mid-caps into their portfolios, which only leads to higher liquidity among these stocks. All in all, as long as the market continues to surge forward, small and mid-caps can be expected to fare better than blue chips (just like 2014)."
Echoing similar views, Nagaonkar said, "The landscape for the Indian business environment looks extremely attractive with a business pro government, depreciating oil prices, improving fiscal deficit and declining inflation."
The Indian markets have lost some lustre this month on emergence of profit-booking as the Sensex fell by 1,778.18 points or 6.22 percent.
The mid-cap index fell by 498.21 points or 4.85 percent, while the small-cap lost 561.08 points or 5 percent.
In terms of valuation, the market capitalisation for the Sensex blue-chip companies rose by over Rs 45.3 lakh crore to Rs 95,51,330 crore so far this year.
This impressive surge came after huge losses suffered by the medium and small stocks last year, benefiting from the revival in investor sentiments since a new government took over in May 2014.
