Another area that has been receiving lots of attention is social media. There's even a social media ETF, the Global X Social Media Index ETF (SOCL). Although some investors have started to talk about a potential "bubble," this group has found tremendous success by monetizing mobile.
The Twitter IPO could offer plenty of future growth opportunity, as the company has successfully figured out mobile and is becoming an established real-time news feed.
Facebook (FB), LinkedIn (LNKD), Twitter and many more likely will continue to see future gains, as the shift to mobile continues to drive revenue for these platforms that register hundreds of millions of users.
Another area of interest is 3D printing. Many people quickly dismiss this as a fad, but honestly, it serves an important purpose. Businesses can save significant time and money by printing out prototypes instead of having to manufacture them.There's not yet huge demand from individual consumers yet, but businesses can reap benefits from using printers from companies such as 3D Systems (DDD) and Stratasys (SSYS), the two big players in the industry. The margins on the printers and materials are huge. Lastly, going green has been causing a stir. Everything from electric cars, solar panels and cleaner fuels has been in play. This is actually a very large category. When I say cars, sure Tesla Motors (TSLA) comes right to mind, but don't forget about Cummins (CMI), which is making the natural gas truck engine, significantly reducing the recurring costs and carbon footprint of using diesel fuel. There are so many things happening around us, and yes, money can and will be made by investing in what's working right now. One certainly shouldn't neglect blue-chip stocks in one's portfolio. But it's also worth doing some homework, looking at some new industries and risking a bit of one's capital on them.
