Time flies by so fast, and with half the year over, Chris Perruna of ChrisPerruna.com offers his watch list for the rest of the year.

The original #13for2013 will remain but due to the popularity on Twitter and Stocktwits, I decided to put together a new list of names, 13 to be exact, for the second half of 2013. I'm a bit hesitant to develop a new list halfway through a year, without using any buy rules, sell rules, or the typical money management techniques that I would employ for actual positions but this is the social web, so let's do it.

The market may be headed for an extended correction due to the weakening NH-NL ratio and also due to the great run it had during the first six months of the year but you never know (trends last a lot longer than anyone can imagine). In addition, the stocks that I have decided to put together are all young, growth companies that can be extremely volatile at times so please proceed with caution and perform your own due diligence. Several of the names listed below are definitely extended from proper buy points but this is for fun, so what the hell.

Ultimately, I will be looking to place positions in several of these stocks over the next six months or longer because I love their products or services and believe that they are in the beginning stages of a prolonged run over the next several years.

For example, I love the idea of gyroscopes and their potential for handheld devices, wearable technology, and industrial capabilities. INVN is my top play in this category.

3D technology fascinates me. Some say it's a bubble but I believe the industry is just scratching the surface. Now, with that said, the stocks in this industry appear to be extended but I am including three candidates on the second half list: XONE, PRLB and DDD (SSYS remains on the original #13 for 2013 list).

Data, big data, and instant data analysis: this category appears to be all the rage these days so why not jump on the train? SPLK is extended from a proper buy point but "why not," let's see if it continues to run higher with strong and increasing institutional support.

Fracking-love it or hate, good or bad, it's most likely here to stay and may provide the necessary natural resources for centuries to come. Silica is used as fracturing sand in connection with oil and natural gas recovery so SLCA covers this base. OAS is engaged in the exploration and production of oil and gas in the northern US, so I have decided to include them on the list as the chart may be gaining some slight momentum.

I own Visa (love the business model) and have for years so why not pick up on two younger companies engaged in a similar business, such as VNTV and XOOM. Whether making an electronic transaction or sending money via the web (to a foreign country), this industry will continue to profit and expand (paper money is a thing of the past). And with all the online and electronic transactions taking place, why not protect your identity and insure yourself from fraud with LOCK.

These are some of the reasons as to why I put this second half list together. The stocks on this list will probably perform well beyond the market if we took a look a few years down the road but for this exercise, we only have six months so let's see how they turn out. The first six months was a huge success so why not repeat that performance with some great companies and even better technologies/products/services!
