Welcome to edition 245 of Insider Weekends. Insider buying tripled last week with insiders buying $168.17 million of stock compared to $56.56 million in the week prior. Selling on the other hand decreased with insiders selling $1.53 billion of stock last week compared to $1.59 billion in the week prior.

Sell/Buy Ratio: The insider Sell/Buy ratio is calculated by dividing the total insider sales in a given week by total insider purchases that week. The adjusted ratio for last week dropped down to 9.12. In other words, insiders sold more than 9 times as much stock as they purchased. The Sell/Buy ratio this week compares favorably with the prior week, when the ratio stood at 28.27. We are calculating an adjusted ratio by removing transactions by funds and companies and trying as best as possible only to retain information about insiders and 10% owners who are not funds or companies.

Insider Sell Buy Ratio February 27, 2015

Note: As mentioned in the first post in this series, certain industries have their preferred metrics such as same store sales for retailers, funds from operations (FFO) for REITs and revenue per available room (RevPAR) for hotels that provide a better basis for comparison than simple valuation metrics. However metrics like Price/Earnings, Price/Sales and Enterprise Value/EBITDA included below should provide a good starting point for analyzing the majority of stocks.

Notable Insider Buys:

1. Sprint Corporation (S): $5.12

President & CEO Raul Marcelo Claure acquired 5,080,000 shares of this telecommunications company, paying $4.92 per share for a total amount of $25 million. Mr. Claure increased his stake by 181.28% to 7,882,330 shares with this purchase.

This is an unusually large purchase by a non-founder CEO and I had to read through the footnotes of the filing carefully to see if it was a mistake. With nothing in the footnotes indicating that this was a mistake and no amended form 4 filed with the SEC, this looks like a legitimate purchase. Mr. Claure has served on the board of directors of Sprint since January 2014 and took over the role of CEO in August 2014.

SoftBank, which owns a majority stake in Sprint is also the majority stakeholder in Miami based wireless distributor Brightstar. Mr. Claure founded Brightstar in 1997 and is estimated to have a net worth north of $1 billion following SoftBank’s purchase of a 57% stake in Brightstar for $1.26 billion.

A balance sheet with more than $31 billion in debt, high cap-ex requirements and a highly competitive business make Sprint a challenging turnaround story. It will be interesting to see if Mr. Claure and SoftBank’s Masayoshi Son can pull off this turnaround.

In the words of Warren Buffett who just released the 50th annual shareholder letter for Berkshire Hathaway:

“When a management with a reputation for brilliance tackles a business with a reputation for bad economics, it is the reputation of the business that remains intact.”
