3 Monster Growth Stocks That Still Have Room to Run

Investors are in the market to make a profit, and that means finding the stocks with proven growth potential. Yes, it’s a cliché to remind everyone that past performance does not guarantee future results, but when a stock consistently shows strong share appreciation, over an extended period, it’s a positive sign for investors.With more than ten months behind us, the stocks that are now showing a combination of strong gains and a high near- to mid-term potential are going to attract investor interest.Bearing this in mind, we set out to find stocks flagged as exciting growth plays by Wall Street. Using TipRanks’ database, we locked in on three analyst-backed names that have already notched impressive gains and boast strong growth narratives for the long-term. Bandwidth, Inc. (BAND)We start in the communications software sector, where Bandwidth is a leading provider of VoIP systems, using its application programming interfaces (API) to offer customers both text and voice capabilities. The company’s products include applications for voice calling, text messaging, local phone numbers via internet, and 911 emergency phone system access. Bandwidth has developed and built its own network for voice over internet, helping to guarantee connectivity.Like many online tech companies, BAND has benefitted from the 2020’s shift to remote work. The move into the virtual office space has put a premium on internet communications, and BAND shares have reflected that – the stock is up an impressive 135% year-to-date. The company’s Q3 earnings were also strong – and at 14 cents per share were far above the 12 cent net EPS loss expected. Revenues for the third quarter came in at $84.8 million, for a 40% year-over-year increase.In addition to positive revenues and earnings, Bandwidth has also shown sound liquidity. The company had over $300 million in cash and cash equivalents available at the end of September, while liabilities totaled only $57.8 million.Finally, earlier this month, Bandwidth completed its acquisition of the European cloud communications company Voxbone. The deal was valued at 446 million Euros, or more than $520 million in US currency. The transaction included 354.6 million Euros in cash, and the remainder in stock.Bandwidth’s growth and healthy future prospects caught the attention of 5-star analyst Michael Walkley. Writing from Canaccord, this top analyst said, “With Covid-19 impacting the way we work, learn, and interact for the foreseeable future, we believe Bandwidth is a long-term beneficiary from anticipated strong growth trends due to increased customer usage of their platform. We believe revenue growth should remain strong given our expectations for some permanent long-term changes with an increased remote work environment driving both increasing usage from existing customers and layering in the potential for stronger new customer growth.”To this end, Walkley puts a Buy rating on BAND shares, and his $225 price target suggests room for nearly 50% upside in the next 12 months. (To watch Walkley’s track record, click here)Overall, BAND gets a Moderate Buy rating form the analyst consensus, based on 5 reviews, including 4 Buys and 1 Sell. The shares are priced at $150.50, and the average price target of $192.20 implies a one-year upside of ~28%. (See BAND stock analysis on TipRanks)Wayfair, Inc. (W)From cloud communications we move on to e-commerce, where Wayfair is a leader in the home goods and furniture sector. E-commerce has seen heavy gains during the COVID pandemic, as customers moved larger portions of their shopping online. The stock shows that, having grown 180% year-to-date.Earnings have also reflected strong sales during the pandemic period. EPS turned positive in Q2, coming in at $2.54 against a 55-cent forecast. In Q3, the earnings per share was $1.80, beating the estimate by 300%. Revenues are high, too, with the $3.8 billion in Q3 representing a 66% year-over-year gain. And like Bandwidth above, Wayfair has a sound balance sheet, with $2.6 billion in cash and liquid assets reported at the end of the third quarter.These fiscal gains stand on the shoulders of solid sales performance. Wayfair reported 11.3 million orders from repeat customers in Q3, making up almost 72% of the quarter’s total orders. Active customers in the company’s Direct Retail business segment increased 50% yoy, and reached 28.8 million.Peter Keith, 5-star analyst with Piper Sandler, writes of Wayfair, “Looking forward, KPI’s repeat customers (% of orders) and revenue per average customer (LTM) both hit all-time highs and suggest Wayfair will grow revenues nicely off a larger base of customers… We maintain our bullish thesis as above-trend sales growth is likely to persist at least into early 2021, and margins are expanding far above expectations – with longer-term drivers coming into focus.”It should come as no surprise, then, that Keith stays with the bulls. In addition to an Overweight (i.e. Buy) rating, he left a $370 price target on the stock. Investors could be pocketing a gain of 47%, should this target be met in the twelve months ahead. (To watch Keith’s track record, click here)Overall, Wayfair has 20 reviews on record, including 10 Buys, 7 Hold, and 3 Sell, making the analyst consensus view a Moderate Buy. W stock is selling for $251.70 and has an average price target of $312.63, making the upside potential 24% for the coming months. (See Wayfair’s stock analysis on TipRanks)Schrodinger (SDGR)Last but not least is Schrodinger, a software company that develops applications for the life sciences and materials sciences industries. In short, the company builds the software platforms that allows customers to evaluate experimental compounds. Schrodinger describes its software as a physics-based platform, integrating solutions for collaboration, data analytics, and predictive modeling in chemistry. The platform is used extensively in the pharmaceutical industry, but also in aerospace, energy, and semiconductors.Schrodinger went public in February of this year, just as the corona crisis was ramping up, and quickly saw strong share gains. At the IPO, the stock sold for $26 per share, well above the initial pricing of $17. The company sold well over 11.8 million shares, making the opening one of the year’s most successful. Since then, SDGR shares have more than doubled, gaining nearly 140% in their first nine months of public trading.Revenues have remained consistent during the year, with the first three quarters of 2020 showing the top line between $23 and $26 million. The Q3 number, at $25 million, is right in the middle of that range. The Q3 top line beat the forecast by 10%Covering this stock for BMO, 5-star analyst Do Kim writes, “We believe the 42% y/y growth in software revenues reflects the accelerating adoption of computational drug discovery, in addition to a growing customer base. We expect software growth to continue into 2021, as we believe the pandemic trend of remote work is sticky, with increasing platform validation from collaborations.”In line with this upbeat outlook, Kim rates SDGR shares an Outperform (i.e. Buy) along with a $94 price target. This figure indicates confidence in a 37% one-year upside potential. (To watch Kim’s track record, click here)All in all, Schrodinger’s Strong Buy consensus rating is based on 3 Buys and 1 Hold. The stock has an average price target of $83, giving it a 21% upside from the current trading price of $68.52.

Fluid in eye cells can 'boil' if you watch the eclipse without protection: expert – Delta Optimist

Published

 on


Millions of people in parts of Eastern and Atlantic Canada will be able to see the rare solar eclipse happening on April 8. But they should only look up if they have proper eye protection, experts say. 

WHY IS WATCHING THE ECLIPSE MORE DANGEROUS THAN LOOKING AT THE SUN ON A NORMAL DAY?

When people look up at the sun normally, the intense brightness triggers pain that causes them to look away quickly before it can cause damage, said Dr. Philip Hooper, president of the Canadian Ophthalmological Society.

300x250x1

But as the moon starts to block the sun in the period leading up to the total eclipse “there is significant light energy that’s coming from the sun, but we don’t appreciate pain. And so you can look at it long enough to do damage to the eye,” said Hooper, who is also an associate professor of ophthalmology at Western University in London, Ont. 

HOW DOES STARING AT THE SUN DAMAGE OUR EYES?

When you’re looking directly at the sun, intense visible light and infrared radiation are focused on the centre of the retina in the back of the eye. 

“It’s basically like taking a magnifying glass in the sun on a normal day and focusing that light on a piece of paper. It can get hot enough to burn the paper,” Hooper said. 

The sun has the same effect, because your eye concentrates that energy into a small area of the retina. 

“The temperature of the cells in that area can actually get high enough that the fluid in the cells actually boils and it damages the cells permanently,” he said. 

CAN I JUST PUT MY SUNGLASSES ON TO WATCH THE ECLIPSE?

No. Sunglasses do not provide protection, Hooper said. 

WHAT IF I STAY INSIDE AND WATCH THROUGH THE WINDOW?

Again, no. Windows offer no protection. 

IS IT SAFE TO WATCH THROUGH A PHONE CAMERA?

No.

“Eclipse or not, you shouldn’t look at the sun directly with the naked eye, or with a camera or telescope, without a (certified) solar filter. This can lead to irreversible eye damage,” says an eclipse safety video posted online by the Canadian Space Agency. 

Pointing your phone camera directly at the eclipse may also have other consequences. 

“Just remember that your camera on your phone has lenses just like eyeglasses do, and that light is coming in from the sun as soon as you open the shutter,” said Elaina Hyde, director of the Allan I. Carswell Observatory at York University in Toronto.

“At the very least you could expect to damage your camera. You won’t be able to see anything, again, because your phone is not able to handle that light.”

HOW DO I SAFELY WATCH THE ECLIPSE?

You’ll need special glasses with filters designed for eclipse watching, says the Canadian Space Agency website. 

Those glasses must have side protection so that light rays can’t enter, said Hooper. 

They must also have certified lenses, he said.

The certificationISO 12312-2 should be printed on the glasses, whichmeans the glasses meet international safety standards.  

While wearing the glasses, you should not be able to see anything unless you’re staring at the sun. 

“No matter how bright a light you are exposed to in your indoor environment, if you shone a very bright light through them, you’d see nothing. They’re totally black. That’s how dark they are,” Hooper said. 

The eclipse glasses should not be used if they are “scratched, punctured, torn, or otherwise damaged,” the American Astronomical Society says on its website, noting that people should inspect their glasses before using them. 

The society also says that children using the glasses during the eclipse must be supervised at all times. 

WHERE CAN I GET THE ISO 12312-2 CERTIFIED GLASSES?

Free eclipse-viewing glasses are available at many libraries, cities and school districts across Canada, according to the Royal Astronomical Society of Canada website.   

The American Astronomical Society has a list of companies and retailers in both Canada and the U.S. that sell certified solar eclipse glasses on its website.  

Some companies selling them in Quebec are listed on the Eclipse Quebec website. 

WHAT ABOUT WELDING GOGGLES?

Welding goggles come in a variety of shades, denoted by number, according to the Canadian Centre for Occupational Health and Safety website. 

The minimum darkness required to safely watch the eclipse is shade 13, said Hooper. 

“That’s much darker than the welding glasses or goggles that are typically used by welders. And they’re not widely available,” he said. 

IF I DON’T HAVE THE CERTIFIED GLASSES, IS THERE ANOTHER OPTION?

Another option for safe viewing is to make a projector so that you are never looking directly at the sun. It can be as basic as a piece of paper with a pinhole that projects the light from the sun onto the sidewalk, or a projector made out of a box. 

The Canadian Space Agency website has simple instructions on how to make a projector using an empty cardboard box, a sheet of white paper, aluminum foil, a pin, tape and scissors.

A total solar eclipse takes place on April 8 across North America. These events occur when the moon passes between the sun and Earth, completely blocking the sun’s face. This plunges observers into a darkness similar to dawn or dusk.

During the upcoming eclipse, the path of totality, where observers experience the darkest part of the moon’s shadow (the umbra), crosses Mexico, arcing north-east through Texas, the Midwest and briefly entering Canada before ending in Maine.

Total solar eclipses occur roughly every 18 months at some location on Earth. The last that crossed the US took place on August 21 2017.

An international team of scientists, led by Aberystwyth University, will be conducting experiments from near Dallas, at a location in the path of totality. The team consists of Ph.D. students and researchers from Aberystwyth University, Nasa Goddard Space Flight Center in Maryland, and Caltech (California Institute of Technology) in Pasadena.

There is valuable science to be done during eclipses that is comparable to or better than what we can achieve via space-based missions. Our experiments may also shed light on a longstanding puzzle about the outermost part of the sun’s atmosphere—its corona.

The sun’s intense light is blocked by the moon during a total solar eclipse. This means that we can observe the sun’s faint corona with incredible clarity, from distances very close to the sun, out to several solar radii. One radius is the distance equivalent to half the sun’s diameter, about 696,000km (432,000 miles).

Measuring the corona is extremely difficult without an eclipse. It requires a special telescope called a coronagraph that is designed to block out direct light from the sun. This allows fainter light from the corona to be resolved. The clarity of eclipse measurements surpasses even coronagraphs based in space.

We can also observe the corona on a relatively small budget, compared to, for example, spacecraft missions. A persistent puzzle about the corona is the observation that it is much hotter than the photosphere (the visible surface of the sun). As we move away from a hot object, the surrounding temperature should decrease, not increase. How the corona is heated to such high temperatures is one question we will investigate.

We have two main scientific instruments. The first of these is Cip (coronal imaging polarimeter). Cip is also the Welsh word for “glance,” or “quick look.” The instrument takes images of the sun’s corona with a polariser.

The light we want to measure from the corona is highly polarized, which means it is made up of waves that vibrate in a single geometric plane. A polarizer is a filter that lets light with a particular polarization pass through it, while blocking light with other polarizations.

The Cip images will allow us to measure fundamental properties of the corona, such as its density. It will also shed light on phenomena such as the solar wind. This is a stream of sub-atomic particles in the form of plasma—superheated matter—flowing continuously outward from the sun. Cip could help us identify sources in the sun’s atmosphere for certain solar wind streams.

Direct measurements of the magnetic field in the sun’s atmosphere are difficult. But the eclipse data should allow us to study its fine-scale structure and trace the field’s direction. We’ll be able to see how far magnetic structures called large “closed” magnetic loops extend from the sun. This in turn will give us information about large-scale magnetic conditions in the corona.

The second instrument is Chils (coronal high-resolution line spectrometer). It collects high-resolution spectra, where light is separated into its component colors. Here, we are looking for a particular spectral signature of iron emitted from the corona.

It comprises three , where light is emitted or absorbed in a narrow frequency range. These are each generated at a different range of temperatures (in the millions of degrees), so their relative brightness tells us about the coronal temperature in different regions.

Mapping the ‘s temperature informs advanced, computer-based models of its behavior. These models must include mechanisms for how the coronal plasma is heated to such high temperatures. Such mechanisms might include the conversion of magnetic waves to thermal plasma energy, for example. If we show that some regions are hotter than others, this can be replicated in models.

This year’s eclipse also occurs during a time of heightened solar activity, so we could observe a coronal mass ejection (CME). These are huge clouds of magnetized plasma that are ejected from the sun’s atmosphere into space. They can affect infrastructure near Earth, causing problems for vital satellites.

Many aspects of CMEs are poorly understood, including their early evolution near the sun. Spectral information on CMEs will allow us to gain information on their thermodynamics, and their velocity and expansion near the sun.

Our eclipse instruments have recently been proposed for a space mission called moon-enabled solar occultation mission (Mesom). The plan is to orbit the moon to gain more frequent and extended eclipse observations. It is being planned as a UK Space Agency mission involving several countries, but led by University College London, the University of Surrey and Aberystwyth University.

We will also have an advanced commercial 360-degree camera to collect video of the April 8 eclipse and the observing site. The video is valuable for public outreach events, where we highlight the work we do, and helps to generate public interest in our local star, the sun.

We know knights in shining armour rode powerful horses, but remains of those horses are rare. Now, researchers studying equine remains from a site near Buckingham Palace have built a case, based on evidence from their bones, that these animals were likely used in jousting tournaments and battle. Archaeologist Katherine Kanne says the bone analysis also revealed a complex, continent-crossing medieval horse trading network that supplied the British elite with sturdy stallions. This paper was published in Science Advances.

In an ice-free Arctic, polar bears are dining on duck eggs — and gulls are taking advantage

Quirks and Quarks9:22In an ice-free Arctic, Polar bears are dining on duck eggs — and gulls are taking advantage

Researchers using drones to study ground-nesting birds in the Arctic have observed entire colonies being devastated by marauding polar bears that would normally be out on the ice hunting seals, except the ice isn’t there. What’s more, now they’re enabling a second predator — hungry gulls that raid the nests in the bears’ wake. Andrew Barnas made the observations of this “gull tornado” by following around polar bears in East Bay Island in Nunavut. The research was published in the journal Ecology and Evolution.

NASA’s Europa Clipper mission, due to launch this fall, is set to explore the jewel of our solar system: Jupiter’s moon, Europa. The mission’s focus is to determine if the icy moon, thought to harbour an ocean with more water than all of the water on Earth, is amenable to life. However, postdoctoral researcher Fabian Klenner, now at the University of Washington, demonstrated how the spacecraft may be able to detect fragments of bacterial life in a single grain of ice ejected from the surface of the moon. The study was published in the journal Science Advances.

Pollution is preventing pollinators from recognizing floral plants by scent

Quirks and Quarks7:50Pollution is preventing pollinators from finding plants by scent

Our polluted air is transforming floral scents so pollinators that spread their pollen can no longer recognize them. In a new study in the journal Science, researchers found that a certain compound in air pollution reacts with the flower’s scent molecules so pollinators — like the hummingbird hawk-moths that pollinate at night — fail to recognize them. Jeremy Chan, a postdoctoral researcher at the University of Naples, said the change in scent made the flowers smell “less fruity and less fresh.”

An Australian Atlantis and underwater archeological remains in the Baltic 

Quirks and Quarks17:14An Australian Atlantis and underwater archeological remains in the Baltic

During the last ice age, sea levels were more than 100 metres lower than they are today, which means vast tracts of what are currently coastal seafloor were dry land back then. Geologists and archaeologists are searching for these lost landscapes to identify places prehistoric humans might have occupied. These included a country-sized area of Australia that could have been home to half a million people. Archaeologist Kasih Norman and her colleagues published their study of this now-drowned landscape in Quaternary Science Reviews

Another example is an undersea wall off the coast of Northern Germany that preserves an underwater reindeer hunting ground, described in research led by Jacob Geersen, published in the journal PNAS.
