There might be another big phone company to add to the growing list of companies that are planning to make major announcements in September, writes MoneyShow's Jim Jubak, also of Jubak's Picks.

Add Nokia (NOK) to the list of phone companies likely to announce a big product in September.

Rumor pegs a big Nokia announcement for a two-day event to be held in New York, maybe, in late September. The event, according to the blogs MyNokia and electronista.com, will launch Nokia's first Windows Phone phablet (a hybrid of a phone and a tablet.) Rumors say the phablet will have a 1080-resolution display, although the size of the screen is even less certain than other details about the product. The device would also be the first Nokia smartphone based on a quad-core chip instead of the dual-core chips in the Lumia 1020.

September is shaping up as a very busy month for phone makers as they attempt to steal some of the thunder from Apple's new iPhone—rumored for launch on September 10. Besides Nokia, Samsung plans a September 4 launch event for a new large-screen Galaxy Note phablet (a phone/tablet hybrid) and a smartwatch called Galaxy Gear.

Apple and Nokia are both members of my Jubak's Picks portfolio.

Full disclosure: I don't own shares of any of the companies mentioned in this post in my personal portfolio. When in 2010 I started the mutual fund I manage, Jubak Global Equity Fund, I liquidated all my individual stock holdings and put the money into the fund. The fund may or may not now own positions in any stock mentioned in this post. The fund did own shares of Apple as of the end of June. For a full list of the stocks in the fund as of the end of June see the fund's portfolio here.
