The market for initial public offerings in 2013 has been rather quiet considering how well the market has been doing since the start of the year. 24/7 Wall St. took a look at the IPOs which have come public in the last 4 months or so and found four IPOs that are up 50% or more. One of those four is up over 100% since coming public.

SolarCity Corp. (NASDAQ: SCTY) may have partly helped save solar, although it is involved in the installation, and sale or lease of solar energy systems to residential and commercial customers rather than being a maker of solar panels. Its shares are still up more than 120% at $19.00 after getting an $8.00 IPO price in the first half of December. Its post-IPO range is $9.20 to $20.38 and its market cap is said to be almost $1.4 billion now.

YY Inc. (NASDAQ: YY) is the online social platform in the People’s Republic of China and its shares are also up about 73% from the November IPO price of $10.50 per ADS. At $18.16 after a 6% gain on Friday, this has a new post-IPO range of $10.50 to $18.78 and its market cap is about $966 million.

Norwegian Cruise Line Holdings Ltd. (NASDAQ: NCLH) is not the cruise liner that stuck its passengers out in the Gulf of Mexico. Shares are up more than 55% even after being down 2% at $29.85 on Friday. This cruise outfit priced at $19.00 in mid-January but its post-IPO range has been $24.16 to $31.91 and its market cap is listed as $627 million.

Western Gas Equity Partners LP (NYSE: WGP) is up over 50% from the $22.00 IPO price in early December. At $34.00, its post-IPO range is $27.12 to $35.53.
