SPECIAL NOTE: The gene editing field provides big-gain potential, but investors must remain vigilant as the science, controversies and patent battles in this field come fast and create volatility and uncertainty. That’s why Senior Stock Strategist Kevin Cook dives into the most exciting real-time revolution unfolding in Biotechnology, maybe in all of medicine, in his newest Special Report, The Greatest Discovery in the Century of Biology. He covers key knowledge areas for investors who want to explore this “breakthrough of the century,” and reveals three key stocks to ride this revolution. Log on to Zacks.com to see these stocks today. Now we have a better chance to enjoy the weekend! The two-day plunge ended on Friday as each of the major indices rallied into the close and finished the session solidly on positive ground. Of course, the week was absolutely horrible, but at least there's hope that we can get back on track as earnings season heats up. Weakness in tech was one of the big weights on the market this week (along with rising rates and slowdown fears). Fortunately, the space rebounded on Friday and helped the NASDAQ to soar 2.29% to 7,496.89. The FANGs were all up with especially solid performances from Netflix (+5.75%), and Amazon (+4.03%). The S&P saw its first (and only) green of the week by jumping 1.42% to 2,767.13, snapping a six-day losing skid. The Dow advanced 1.15% (or about 287 points) to 25,339.99. That bounce back was just a drop in the bucket compared to the approximately 1400-point loss in the previous two days…but you’ve got to start somewhere. The week was still atrocious with each of the indices plunging by about 4%. And the market was especially cruel today as stocks soared in the morning and gave nearly all of it back by mid-day. But just when everyone was getting ready to give up, the last couple of hours moved sharply in the right direction. For example, the Dow wasted a more than 400-point rally at its best before rebounding. “The big question after today is whether or not the last two-days formed some type of bottom or if this was just a relief rally. That depends on a lot of factors, but there has been a lot of damage done to the technicals and until the charts look healthy again I will remain cautious,” said Jeremy in Counterstrike. Friday was also the unofficial start to earnings season. Big banks such as J.P. Morgan Chase, Wells Fargo and Citigroup kicked things off with solid reports that included better-than-expected earnings. Investors are looking for anything that could help stabilize this market as we finish out the year, and a strong earnings season would be just what the doctor ordered. And it is expected to be pretty good with earnings growth of more than 18% and revenue growth of more than 7%. Of course, it would also be amazing if the U.S. and China could get together and figure out their trade problems…but you probably shouldn’t hold your breath waiting on that one. Today's Portfolio Highlights: Momentum Trader: Now that the market has recovered a bit, its time for Dave to pick up a company that’s poised to jump after getting beaten down. Comtech Telecom (CMTL) is now lingered around $32. The last time that happened, this stock bounced twice. The CCI suggests that may be about to happen again. The editor also likes this company’s history of earnings outperformance, which included a 60% surprise last quarter and a 136% beat over the past four. Read the complete commentary for more on CMTL. TAZR Trader: Once all the fears of a pullback subside, new opportunities present themselves. Now that the market has stopped the bleeding (for now), Kevin sees an intriguing idea with Align Technology (ALGN). This maker of Invisalign “smile makers” has already been a 57% winner for the portfolio. The editor has always liked this name, but now he’s fallen back in love with it after a more than 20% decline during the sell-off. He added ALGN again on Friday with a 10% allocation and is feeling pretty good about its quarterly report on October 24. Read the complete commentary for a lot more on this name. Technology Innovators: In the midst of a sharp sell-off, you tend to pay attention to those stocks that hold up better than others. So Twilio (TWLO) really caught Brian Bolan’s eye yesterday. This Zacks Rank #1 (Strong Buy) provider of cloud communications platforms is still down from recent highs, but its resilience has the editor thinking that an uptrend is in the cards. Therefore, he added TWLO to the portfolio. Read the complete commentary for more. Options Trader: "With the first half of October behind us, let’s take a quick look at the reasons why the second half is likely to be much, much better. "1) Earnings season is now underway, and for the last 9½ years, the market’s gone up on average of 1.5% during earnings season. And if the previous earnings season was up (which it was), there’s a 73% chance the next earnings season will be up too. "2) October, historically speaking, is the best month for stocks. (It’s also notorious for being the most volatile, as we’ve already seen.) But also the most profitable. "3) And October, November, and December are the three best months in a row for the market. "So there’s a lot to look forward to." -- Kevin Matras Have a Great Weekend!
