Tata Motors (NYSE: TTM - option chain) shares are headed higher today as the company officially begins booking sales of its Nano today. The car has been called the world's cheapest automobile, and analysts are eagerly waiting to see how well the car sells in rapidly-growing India. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on TTM.

TTM opened this morning at $6.96. So far today the stock has hit a low of $6.95 and a high of $8.30. As of 11:45, TTM is trading at $7.65, up 1.01 (15.2%). The chart for TTM looks neutral and S&P gives TTM a 3 STARS (out of 5) hold ranking.

As if Detroit didn't have enough to worry about, Tata Motors (NYSE: TTM) has unveiled its long-awaited super-cheap car at the Auto Expo in New Delhi. Called the Nano, it's tiny and kind of cute, in a smooshed jelly bean kind of way. Its most attractive feature, though, is its price. For a mere 100,000 rupees, the equivalent of roughly $2,500, you can drive home in the world's least expensive car (assuming you live in India, of course).

According to AutoBlog, here's what you get for your 100,000 rupees: a two cylinder gasoline engine producing a whopping 30 horsepower, a four-speed manual transmission, room for five (very small) people, brakes of some kind, and, best of all, 54 miles per gallon of gas. You don't get a radio or power steering or a second windshield wiper, but did you really expect to? Even so, the car is reasonably safe and efficient by Indian standards, and Tata claims that it meets all environmental and safety regulations in India.

It's hard not to be impressed by the Nano, and by the potential of Tata Motors. Tata is already the largest auto manufacturer in India. Millions of Tata vehicles are already on the roads, and with the Nano, we can expect to see millions more. Tata also sells cars and trucks all over Asia and has a growing presence in the Middle East and Latin America. If you want to place a bet on the future of the global auto industry, you could do worse than buying some Tata stock. Just as General Motors (NYSE: GM) and Ford (NYSE: F) provided basic transport in the world's fastest growing economy early 20th century, Tata is poised to sell millions of basic cars in the fastest growing part of the world in the 21st century.

As my colleague Georges Yared is fond of saying, Apple, Inc. (NASDAQ: AAPL) continues to ride the train to riches every year, as it rolls out new iPod products while increasing its share of the PC market slowly but surely. As I write this, Apple shares stand at a new all-time high of $153.18. Is it time to get into these shares, or has the time passed? Those who bought in at $80 a share are probably grinning right now, as an almost 100% return may be on the horizon soon.

But, like Georges, I believe Apple shares are headed even higher. The popular iPod line has been around for over five years now, and the new generation is better than ever. The snazzy new iPods create buzz around Apple's music products and other products like the Mac computer line, and the company's word-of-mouth and visual marketing continues to shine with the mass consumer.

Apple goes beyond the "features for the money" approach of other digital music players. Buying an Apple product is now a cultural statement and provides a feeling of being in the "in crowd." Over and over again, there are arguably better products that try to compete with the iPod, but none have succeeded thus far because they cannot match that special feeling.

As I was following Apple. Inc.'s (NASDAQ: AAPL) "The beat goes on" event yesterday, I caught myself wondering this: can Apple roll out incremental features to its iPod line and get the market excited once again? I'm not sure that happened, as Apple shares remained stagnant during the event and then closed down almost nine points. This on a day when the company refreshed its entire iPod lineup with new "models." Ehh.

Did Apple just suffer along with many other tech stocks in yesterday's downtick, or was it something more? Apple CEO Steve Jobs has a wonderful way of making the world think each 'new' Apple product is somehow a first or one-of-a-kind, but most aren't any longer when it comes to the iPod line (save the iPhone, which is easily a revolutionary product).

Basically, Jobs trotted out the same products -- from the iPod Classic to the iPod Nano to the iPod Touch -- with incremental feature upgrades and more marketing glitz than a glazed donut. The market seemed unimpressed, all things considered. But, there's more.

No sooner had rumors of the Apple, Inc. (NASDAQ: AAPL) iPhone become plausible than rumors of an iPhone Nano began floating about: a cheaper, smaller version of the smartphone killer. And though most of the energetic rumors around Wednesday's super-secret Apple announcement seems to be focused on the possible release of the Beatles on iTunes and some outrageously tiny new Nano, the Washington Post, in a fluffy piece this weekend, stated it had received documents confirming the existence of the iPhone Nano and a wireless-enabled iPod. Not only would the wireless iPod be supercool (ok, the Post didn't say that), it would also have touch screen capabilities.

Much as I revere the Beatles, an iPhone Nano for Christmas would get me way more excited about Apple's prospects come this holiday season than the availability of Sergeant Pepper's Lonely Hearts Club. If the past is any indication (and with Apple, history does seem to repeat itself), these rumors -- and general Applexuberance -- will send the stock even higher than its close of $138.48 August 31.

In early July, a JPMorgan analyst announced that the iPhone Nano would soon be released at a price point of $300; his employer later debunked his claim (although the buzz on the street seems to be that we all know it will happen eventually).

Last week, PortalPlayer released news that it would not be supplying its digital chips for the next version of the iPod Nano. The report implied that Apple would be redesigning the guts of the tiny but wildly popular music device and spurred interest in potential details.

Now, the first reports are surfacing which provide some details on when the new Nano will be released and what design features it might possess. AppleInsider is reporting that a release date may be scheduled for September in time for the Christmas buying splurge.

The report also suggests that the new Nano will have a "significant internal redesign" which leaves those of us who obsessively follow new Apple products to speculate on which companies might be tapped to supply the replacement chips.
