Yes, gifts of stock are considered contributions of noncash property.
It is important to note that a number of special considerations and requirements apply to stock, depending on the nature and value of the contribution. For example, publicly traded stock contributed to a church or charity must be documented by the donor on Part A of Form 8283. Additionally, the donor must obtain a proper acknowledgment from the church or charity substantiating the stock gift. (The Form 8283 alone is not adequate substantiation to support a charitable contribution deduction for a gift of noncash property valued at $250 or more, including stock.)
You can get further guidance from a qualified CPA or from Chapter 3 of my book, Church Finance.
