If there was ever a week where we saw disproportionate numbers in insider activity, it was this week. Insiders from every sector took advantage of the gigantic wash-out last Monday and Tuesday, as well as the damage from the prior week, to load the boat. While this should come as no surprise, it is a super bullish anecdotal tidbit that will not be lost on Wall Street.

We cover insider buying every week at 24/7 Wall St., and we like to remind our readers that while insider buying is usually a very positive sign, it is not in of itself a reason to run out and buy a stock. Sometimes insiders and 10% owners have stock purchase plans set up at intervals to add to their holdings. That aside, it still remains a positive indicator.

Here are some of the companies that reported notable insider buying this past week.

Sprint Corp. (NYSE: S) had a huge 10% owner of the stock return in a gigantic way. Once again, Softbank Group was buying shares, and this time the company purchased an astounding 21,327,788 shares of the carrier at prices that ranged from $4.38 to $4.87 apiece. The total for this massive purchase came to $100.2 million. Shares were trading on Friday’s close at $5.19, so again, a well-timed purchase.

Cimpress aggregates small and individually customized orders for print, signage, apparel and similar products worldwide. Its conducts its operations through Vistaprint Business Unit and All Other Business Unit segments. The shares closed trading on Friday at $73.46, so a solid buy.

Level 3 Communications Inc. (NYSE: LVLT) hits our screens for the second time this summer, as a 10% owner was again buying stock. STT Crossing picked up a 200,000-share chunk of the stock at prices between $46.55 and $47.65. The total for this purchase came in at $9.4 million. Level 3 provides transport services comprising wavelengths, private lines, transoceanic and dark fiber, as well as related professional services, fiber services and colocation and data center services.

Sears Holdings Corp. (NASDAQ: SHLD) had a well-known investor once again buying shares of the iconic retailer this past week. Chairman and CEO Eddie Lampert added shares in a big way. The 376,572 shares of the venerable retailer he bought at prices that fell between $21.78 and $23.00 cost him around $8.5 million.

Tesla CEO and founder Elon Musk purchased an additional 123,510 shares of the solar company at prices in a range of $34.82 to $45.35. The total for the buy came to a tidy $5 million.

These companies also reported insider buying this week: La Jolla Pharmaceutical Co. (NASDAQ: LJPC), MasTec Inc. (NYSE: MTZ), MPLX L.P. (NYSE: MPLX), SunEdison Inc. (NYSE: SUNE) and Symantec Corp. (NASDAQ: SYMC).

The overwhelming cascade of buyers should come as no surprise, given the huge drops in the market over the past week and a half. It is always a bullish sign when top insiders add to positions during a steep sell-off, and they did in spades last week.
