MOSCOW, Oct 1 (Reuters) - Shares in Russian homebuilder PIK fell around 12% on Friday, after a company subsidiary sold PIK shares via a secondary public offering (SPO) that analysts said attracted strong demand.

The sale of about 4.1% of PIK's share capital was priced at 1,275 roubles ($17.50) per share. PIK's shares were at around 1,265 roubles by 0836 GMT. The shares had hit a record high of 1,509.6 roubles on Sept. 21.

PIK said on Friday the net proceeds of the offering would be approximately 35.9 billion roubles ($493 million), slightly missing an original $500 million SPO target.

PIK on Wednesday had said its LCC PIK INVESTPROEKT subsidiary would offer around 27 million of PIK's shares, about 4.1% of share capital, in the offering and use the proceeds to buy part of VTB Bank's stake in the company.

Sergei Gordeev, PIK's chief executive officer, owns a 59.3% stake in the company, while VTB holds 23% and the remaining 17.6% is the free float, PIK's website shows.

Russia is in the midst of a flurry of listing activity. IT company Softline on Thursday announced plans for an initial public offering (IPO) in London, following in the footsteps of Renaissance Insurance, which on Monday said it planned a Moscow market debut.

Mercury Retail Group is aiming to raise more than $1 billion in a Moscow IPO by the end of the year, three financial market sources told Reuters on Thursday.

Alongside PIK this week, farming conglomerate Rusagro also successfully closed an SPO. The two deals are the largest in their industries in Russia in more than a decade, Boris Kvasov, head of equity capital markets at VTB Capital, said.

"Both were closed with a discount of just under 9% to their trading price prior to deal launch, both attracted a large amount of high-quality demand and the order books were oversubscribed several times, which allowed (them) to increase the initial offer volume," Kvasov said.

"Looking at the PIK placement, it is worth noting the rather high activity of American investors, whose share in the total demand was about 25%." ($1 = 72.8650 roubles) (Reporting by Tatiana Voronova and Olga Popova; Writing by Alexander Marrow. Editing by Jane Merriman)
