The stock marketplace closed an up-and-down week using the very clear separation of the haves and have-lesses.Big Tech dominated the day due to a trio of mega-cap earnings stinks. Apple (AAPL, +10.5%) taken to fresh all-time highs after its Thursday night report, in which it said quarterly earnings jumped 11% year-over-year and declared that a 4-for-1 stock divide effective in August. It did state, however, it believes iPhone supply is going to be postponed a few weeks that this fall.Amazon.com (AMZN, +3.7%) crushed earnings and profit expectations equally, and its own grocery earnings plummeted year-over-year. Many analysts reacted by revising their price goals higher, such as Canaccord Genuity’s Maria Ripps and Michael Graham. The set see AMZN stocks hitting $3,800 within the following 12 months, up from $3,300 previously.”With customer buying behaviour changing online at an accelerating rate, structural competitive benefits around scale and fulfillment, and a sensible ~2x multiple on eCommerce GMV forcing nearly all of our evaluation, we nevertheless find AMZN stock quite persuasive and believe much of the power will persist past the present pandemic,” that they write.Facebook (FB, +8.2%), meanwhile, reported Q2 earnings that improved by double digits. Additionally, active consumer figures climbed more than anticipated, and average revenue per user was much better compared to Street forecast.Other regions of the market did not seem so powerful. Chevron (CVX, -2.7%) and Exxon Mobil (XOM, +0.5%) both reported quarterly declines, along with the Dow ended with a muted 0.4% profit to 26,428 after being in the red much of the day. The S&P 500 was a little better at +0.8% 3,271, and their small-cap Russell 2000 dropped by 1% to 1,480.But the tech-laden Nasdaq cruised 1.5% higher to 10,745, where it’s flirting yet again with new all-time highs.Winners and also Losers Are Separating Again”The stock market isn’t that the economy,” you’ve likely heard in recent months. It’s certainly true, but the market is indeed starting to show signs of more accurately reflecting what’s going on in the economy, as tech companies positively impacted by COVID-19 continue to climb greater while more economically sensitive stocks sag.”There’s people going on about the bubble in big tech, but my own personal take on that, which was only reinforced by last night (when Apple, Amazon and Facebook reported), is that it’s not a bubble in big tech,” says Will Rhind, founder and CEO of ETF provider GraniteShares. “It’s a bubble in the rest of the market that arguably has been propped up way beyond fundamentals due to the financial intervention of the central banks.””But these companies at the top, you can argue about whether they should be at the valuations that they are, but these are companies that are making incredible sums of money and been incredible beneficiaries of the coronavirus. I think there’s been a dislocation that’s happened between the virtual economy, in which these companies thrive in, versus the real physical economy, where you have airlines, hotels, things that have been decimated.”If the U.S. recovery is indeed hobbled by extended Washington bickering over a fresh stimulus package and coronavirus flare-ups, among other headwinds, investors might need to tweak their portfolios to suit.For instance, more people are clearly favoring gold, which rose another 1% to new highs at $1,985.90 per ounce Friday and extended the 2020 rally in gold-focused funds. Assets under management in larger physical gold funds, such as the SPDR Gold Shares (GLD) and iShares Gold Trust (IAU), have swelled by more than 70% in 2020, according to Ycharts data. Smaller funds, such as the GraniteShares Gold Trust (BAR) and Aberdeen Standard Physical Gold Shares ETF (SGOL), have more than doubled their AUM.It also might be time to shake loose weaker positions that could sink in a broad-marketplace selloff, such as these 14 vulnerable-looking stocks.Another way to look for red flags? Short interest. By looking at how heavily Wall Street is betting against a stock, you can get an idea of just how negative the prospects might be for those shares going forward.The bears don’t always get it right, of course, and sometimes their targets are “squeezed” higher good news, making heavily shorted stocks a playground for opportunistic traders. But if you’re looking to play it safe, consider steering clear of these 18 stocks, that are among the most profoundly shorted on Wall Street.Kyle Woodley was AMZN, BAR and FB for this writing.
