Peter Kamin, a director and major holder with over 10 percent of shares in Tile Shop Holdings (TTS), recently bought another 426,295 shares. This increased his stake by over 7.7 percent, and came to a total just over $750,000.

Insiders have been net buyers in the past year, largely by Karmin and another director that also has a stake over 10 percent. All told, insiders own just under 80 percent of shares.

Tile Shop Holdings, a retail outlet for natural stone and man-made tiles with over 141 stores in 31 states, has seen shares decline by nearly 80 percent in the past year. That level of drop is far in excess of the company’s operational performance, which has shown a mere 4 percent revenue decline in the past year.
