Holding Company Benefits and Advantages
The holding company generally produces no products or services and is simply a vehicle for owning shares of other companies. If the holding company owns 80 percent of the voting stock of another company (the subsidiary), the holding company can qualify for tax-free dividends. Another benefit is the reduced risk exposure. The only risk the holding company has is the capital invested. The holding company also benefits from the subsidiary's goodwill and reputation, while being sheltered from risks faced by the subsidiary in the case of legal issues, tax liabilities and lawsuits.
Sentiment: Strong Sell
Technically it's not taking it "private," as Softbank is a publicly traded company. Nor is Softbank trying to buy all of the shares of S, at least not right now. Softbank had a PPS of $7.65 for S at the 70% buyout deal. What Son is doing now, is what Warren Buffet does. Look at the fundamentals, determine your buy in price, and, if the market drops the price lower than what you bought in at, based on your analysis of the value of the fundamentals, then buy even more.
