In 1990, Microsoft was a “safe” company. Today it is very risky:
From 1985 to 1990, its revenues had increased by 851%. However, since 2013 they have only increased by 43%.
In 1990, its debts were 17% of its revenues, but today debts are 49% greater than revenues.
In 1990, its Price to Sales ratio was 5.84, which was already very high. Microsoft’s current Price to Sales ratio, however, is a more excessive 6.68.
