Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Indian carmaker Tata Motors (NYSE: TTM) were up more than 10% in intraday trading on excitement over the company's sales projections.

So what: Tata announced that it expects sales from its Ace family of light commercial vehicles to be up more than 50% from last year. In units, the company is expecting as many as 250,000 versus a tally of 160,000 last year.

Now what: Commercial vehicles are a key piece of Tata's business, so it's little surprise that talk of the hefty sales bump got investors excited. Tata's stock has been on an absolute tear since earlier in the year and has more than doubled since May. It seems as if the stock is overdue for a cooling off, but at the same time the valuation doesn't look overly pricey. While most U.S. investors are still busy kicking around GM (NYSE: GM), Tata may be a better car company to have on your radar.
