Was ist das eigentlich? Cyberrisiken verständlich erklärt

Es wird viel über Cyberrisiken gesprochen. Oftmals fehlt aber das grundsätzliche Verständnis, was Cyberrisiken überhaupt sind. Ohne diese zu verstehen, lässt sich aber auch kein Versicherungsschutz gestalten.

Beinahe alle Aktivitäten des täglichen Lebens können heute über das Internet abgewickelt werden. Online-Shopping und Online-Banking sind im Alltag angekommen. Diese Entwicklung trifft längst nicht nur auf Privatleute, sondern auch auf Firmen zu. Das Schlagwort Industrie 4.0 verheißt bereits eine zunehmende Vernetzung diverser geschäftlicher Vorgänge über das Internet.

Anbieter von Cyberversicherungen für kleinere und mittelständische Unternehmen (KMU) haben Versicherungen die Erfahrung gemacht, dass trotz dieser eindeutigen Entwicklung Cyberrisiken immer noch unterschätzt werden, da sie als etwas Abstraktes wahrgenommen werden. Für KMU kann dies ein gefährlicher Trugschluss sein, da gerade hier Cyberattacken existenzbedrohende Ausmaße annehmen können. So wird noch häufig gefragt, was Cyberrisiken eigentlich sind. Diese Frage ist mehr als verständlich, denn ohne (Cyber-)Risiken bestünde auch kein Bedarf für eine (Cyber-)Versicherung.

Today's Analyst Stock Ratings | Upgrades, Downgrades

What Are Analyst Stock Ratings?

Analyst ratings measure the expected performance of a stock during a given time period. Analysts and brokerage firms often use ratings when they issue stock recommendations to stock traders.

Analysts arrive at stock ratings after they research companies’ public financial statements, communicate with executives and customers and interact with companies in other ways.

Most analysts issue ratings 4 times a year, usually at 3-month intervals.

How to Use Analyst Ratings

As an investor or trader, you want to be able to use analyst ratings effectively. Here are steps you can take to understand how to synthesize all the information analysts report about a particular company and how to apply it to your own trades. 

Step 1: Check Ratings History

In the short term, look to see whether analysts suggest an initiation, upgrade or downgrade for a particular stock. Understand how the rating changed compared to the previous rating and whether a price target gets announced or changed.

Sometimes the rating stays the same and only the price target changes, which could cause the stock to move in either direction, depending on the significance of the change between the 2 price targets.

Step 2: Check for Other News

In the short term, check to see how the stock reacts to positive or negative news. This will be an indication of the company’s outlook because analyst ratings usually come out after the company announces news (it’ll typically be earnings news).

Step 3: Look at the Sector for News

Check to see if other stocks in the sector also received similar ratings. This could indicate micro news, which refers to when the whole sector or specific company trades in a specific way due to news outside of one company.  

Step 4: Look at the Note

If available, look over the analyst note itself. The beginning of the note has the main information of the rating and price target. Investors should also take a look at the summary of the note, which you can find in the first couple pages and provide you a concrete overview of the company. This can help you get an understanding of how analysts arrived at their thesis on the stock.

Step 5: Make a Decision

After reviewing the analyst ratings (and whether the analyst proposes a change or initiation) and find the reason for that note. Make a decision based on the analyst thesis on the company. This should provide you guidance on how to make your thesis. Analyst ratings are a good indication of what professionals believe the company or sector will do, helping you get a better understanding of the companies you’re interested in. 

Analyst Rating Accuracy

Analyst ratings are not set in stone and nobody knows indefinitely what a stock will do. Therefore, analyst ratings should be taken as an educated guess made by professionals who carefully study the specific company and sector in question. It's not a surprise that the accuracy of each rating can vary by each individual analyst and specific ratings on companies. 

In other words, there’s no hard number or percentage on how accurate analyst ratings are because they are like educated guesses on what they think the stock will do based on their research, within that particular sector. In addition, each firm has so many analysts and so many different companies to review that you can compare ratings to glean what you believe is the truth.

Where Analyst Ratings Come From

Analyst ratings come from stock analysts. Analysts “go deep” on companies within a particular industry or sector. Some analysts employ a top-down approach (they start with an industry or sector and look for excellent companies within that industry or sector) and other stock analysts choose a bottom-up approach, which means they start with the company first and connect the dots within that company’s sector or industry. Analysts evaluate:

  • Financial statements
  • Economic fundamentals
  • Suppliers, customers and competitors
  • Management quality
  • Business model
  • Revenue
  • Expenses 
  • Assets 
  • Liabilities 
  • While these evaluations are done using facts and figures that any investor can access, they come down to a conclusion the analyst must draw. While this isn’t an unqualified opinion, analysts will disagree because their interpretations of the data could vary.

    Types of Stock Ratings

    Stock ratings can range from simple “buy” and “sell” ratings to “equal weight” and “outperform” ratings. Here’s a quick overview of how analysts rate stocks.

    Buy Rating

    A “buy” rating indicates that an analyst is optimistic about a stock’s short-term or mid-term growth and recommends that traders purchase the stock. An analyst may even go so far as to indicate that a stock is a “strong buy.” At the same time, you may choose to swing trade the asset for a profit and come back later to start the process all over again.

    Sell Rating

    A “sell” rating means that an analyst believes the stock will trend downward in a particular time frame. Analysts might even refer to a security as a “strong sell.” Remember, though, you may want to swing trade and come back to this asset in the future even though you just chose to sell, just as you would under a “buy” rating.

    Hold

    A “hold” rating suggests that investors should not buy more of or sell the specified stock because they believe the stock should perform in a way that’s consistent with the market or will perform similarly to comparable companies within that particular sector. This is akin to the value investing approach that Warren Buffett uses, looking to gain long-term value from a single stock rather than flipping it because of a bad week. As many have said, it’s not a loss until you sell.

    Underperform

    An “underperform” rating means an analyst indicates that a stock is expected to perform below the market or sector average. And yes, while the underperform rating may not bode well for an asset in the next few weeks, it may not stay that way. Continue to carefully monitor your portfolio to ensure that an underperforming asset hasn’t turned itself around. As companies are faced with the Herculean task of pleasing shareholders, they will push to fix their underperforming stocks, meaning that a stock you wrote off could rise again.

    Outperform

    An “outperform” rating means that an analyst expects a stock to outperform the market or sector average. While the stock may look to outperform the market or a sector’s average, that doesn’t mean it will continue to soar forever. You must look at an outperform rating as what that asset will do in recent times, but it may not maintain that trajectory.

    Equal-Weight 

    An equal weight rating means that an analyst believes that an individual stock's performance will tie to the average of all the stocks that an analyst covers in that particular sector. This type of rating helps investors get a true comparison of stocks to each other within a particular sector or industry. At the same time, equal-weight ratings could change at any time.

    Price Target 

    A price target is an analyst’s projection of a stock’s future price. A price target is generally set up in a general trade or area where the asset might land. This means that the analyst could get close without hitting the figure on the head. Even so, the analyst wants to get close and better predict the movement of the marketplace and the asset.

    Understanding Stock Ratings

    Stock ratings are exams of the investment potential of a particular stock. They are typically created by financial analysts who evaluate a company's financial performance, competitive positioning, and market outlook to provide guidance on the stock's expected future performance.

    Ratings typically range from "buy" to "sell," with variations in between, such as "hold," "accumulate," or "neutral." A "buy" rating suggests that the stock is likely to perform well in the future, and investors should consider purchasing it. Conversely, a "sell" rating indicates that the stock is expected to underperform, and investors should consider selling it.

    It's important to note that ratings are not guarantees of performance and should not be relied upon solely when making investment decisions. Ratings are just one factor to consider when evaluating a stock's potential, and investors should also conduct their own research and analysis to make informed decisions.

    Another thing to keep in mind is that different analysts may have different opinions on a stock, so it's a good idea to consider multiple ratings before making an investment decision.

    In addition to analyst ratings, investors can also consider other factors when evaluating a stock, such as its financial statements, management team, industry trends, and overall market conditions. By combining all of these factors, investors can make informed decisions about which stocks to buy or sell.

    In summary, stock ratings are an important tool for investors to consider when evaluating a stock's potential, but they should not be the only factor used in investment decision-making. It's important to conduct your own research, consider multiple ratings, and take into account other factors before making an investment decision.

    Should You Use Analyst Ratings to Inform Your Own Trades?

    You can definitely use analyst ratings to inform your own trades and inform your own thesis but it’s a good idea to do your own research. However, analyst ratings are just one step in what should be a much larger investment strategy. Don’t fall in love with just one analyst. Compare notes. Look into how these ratings match with activity on the market and current events. Plus, remember that an analyst rating could easily be incorrect. No one is perfect, but these ratings are a good place to start.

    What Is a Partial Thromboplastin Time Test?

    Here’s the routine when you get a cut: apply some pressure, the bleeding stops, slap on a bandage if you need one. Seems easy enough from the outside. But inside your body, even a little nick from shaving kicks off a series of complex steps to stop the bleeding.

    One of those steps is to send a bunch of proteins -- called clotting factors -- to the injured area. They fit together in a very specific way to make a blood clot, which is basically a solid lump of blood that stops up the bleeding and helps healing begin.

    That’s how it’s supposed to work. When it doesn’t, you may find that you bleed or bruise easily or that you get clots in your blood vessels when you shouldn’t.

    That’s when your doctor might order a partial thromboplastin time (PTT) test, which measures how many seconds it takes for your blood to clot.

    What Does a PTT Test Look For?

    Your body makes several different clotting factors. A problem with any of them -- if it’s missing, broken, or you don’t have enough -- can affect how long it takes a clot to form, if it forms at all.

    A PTT test looks at one set of these factors to see how well they’re working. It’s often done along with another test, called the prothrombin time (PT) test, which looks at another set of clotting factors.

    Together, they provide your doctor a more complete picture of what happens in your body when a clot forms.

    Why Would I Need One?

    Your doctor might order this test to check for a bleeding disorder, such as hemophilia or von Willebrand disease. Symptoms of bleeding disorders include:

  • Bleeding or bruising easily
  • Blood clots that form when they shouldn’t
  • Blood in your poop or urine
  • Gums that bleed easily
  • Heavy menstrual periods in women
  • Nosebleeds
  • Swelling or pain in your joints
  • You’d also need this test if you get heparin therapy -- that’s a medicine used to prevent or treat blood clots after you’ve had an issue like a heart attack or stroke. The PTT test helps make sure you get the right dose. You want to prevent dangerous clots, but still let your blood clot when you need it to.

    You may also get the test to: 

  • Check that your blood clots normally before you go in for surgery
  • Look for a problem with your immune system (some immune system conditions make clots more likely to form -- in women, that can also lead to miscarriages)
  • See how well your liver’s working, since it makes the clotting factors
  • Continued How Do I Prepare for It?

    There’s nothing special you need to do to get ready.

    Let your doctor know about any medicines, herbs, vitamins, or supplements you take, including over-the-counter, prescription, or illegal drugs. Many common meds, such as blood thinners, aspirin, and antihistamines, might affect your results.

    What Happens During the Test?

    This test is a basic blood draw and takes just a few minutes. A lab tech will:

  • Clean your skin where the needle goes in
  • Wrap a rubber strap around your upper arm -- this creates pressure to make your veins swell with blood
  • Insert a thin needle into a vein, usually on the inside of your arm at your elbow or in the back of your hand
  • Draw the blood
  • Remove the rubber strap and put a bandage on your arm or hand
  • Are There Any Risks?

    Typically, you’ll feel a prick when the needle goes in. That’s usually the worst of it, but since you’re having your blood drawn, there is a small chance of things such as:

  • Bleeding or bruising
  • Feeling dizzy or lightheaded
  • Infection
  • What Do the Results Mean?

    The test tells you how many seconds it took your blood to form a clot. What’s normal varies with different labs, so check with your doctor to help you understand what your numbers mean.

    Usually, you get the results within a few hours or a day, but it depends on your lab.

    A typical value for a PTT is 60 to 70 seconds. There’s also an activated PTT (aPTT) test that measures the same thing, but they add a substance to your blood to make it clot faster. A typical aPTT value is 30 to 40 seconds.

    If you get the test because you’re taking heparin, you’d want your PTT results to be more like 120 to 140 seconds, and your aPTT to be 60 to 80 seconds.

    If your number is higher than normal, it could mean several things, from a bleeding disorder to liver disease. You’ll usually get other tests at the same time depending on what your doctor’s looking for.

    If your number is lower than normal, which doesn’t happen often, you may have a higher chance of getting blood clots and, for women, having several miscarriages. You’ll likely get more tests to find out what’s going on.

    Continued Will I Get Other Tests at the Same Time?

    It depends on what your doctor’s looking for. To learn more about how your blood clots, you may get tests such as:

  • Activated whole thrombin time test (ACT)
  • Prothrombin time test (PT)
  • Thrombin time test (TT)
  • Other tests you might get include:

  • Dilute Russell viper venom test (DRVVT) to test for lupus anticoagulant, a sign that you have an immune system problem
  • Platelet count, if you’re getting heparin therapy
  • von Willebrand factor to check if you have von Willebrand disease

    Warum sind Cyberrisiken so schwer greifbar?

    Als mehr oder weniger neuartiges Phänomen stellen Cyberrisiken Unternehmen und Versicherer vor besondere Herausforderungen. Nicht nur die neuen Schadenszenarien sind abstrakter oder noch nicht bekannt. Häufig sind immaterielle Werte durch Cyberrisiken in Gefahr. Diese wertvollen Vermögensgegenstände sind schwer bewertbar.

    Obwohl die Gefahr durchaus wahrgenommen wird, unterschätzen viele Firmen ihr eigenes Risiko. Dies liegt unter anderem auch an den Veröffentlichungen zu Cyberrisiken. In der Presse finden sich unzählige Berichte von Cyberattacken auf namhafte und große Unternehmen. Den Weg in die Presse finden eben nur die spektakulären Fälle. Die dort genannten Schadenszenarien werden dann für das eigene Unternehmen als unrealistisch eingestuft. Die für die KMU nicht minder gefährlichen Cyber­attacken werden nur selten publiziert.

    Aufgrund der fehlenden öffentlichen Meldungen von Sicherheitsvorfällen an Sicherheitsbehörden und wegen der fehlenden Presseberichte fällt es schwer, Fakten und Zahlen zur Risikolage zu erheben. Aber ohne diese Grundlage fällt es schwer, in entsprechende Sicherheitsmaßnahmen zu investieren.

    Erklärungsleitfaden anhand eines Ursache-Wirkungs-Modells

    Häufig nähert man sich dem Thema Cyberrisiko anlass- oder eventbezogen, also wenn sich neue Schaden­szenarien wie die weltweite WannaCry-Attacke entwickeln. Häufig wird auch akteursgebunden beleuchtet, wer Angreifer oder Opfer sein kann. Dadurch begrenzt man sich bei dem Thema häufig zu sehr nur auf die Cyberkriminalität. Um dem Thema Cyberrisiko jedoch gerecht zu werden, müssen auch weitere Ursachen hinzugezogen werden.

    Mit einer Kategorisierung kann das Thema ganzheitlich und nachvollziehbar strukturiert werden. Ebenso hilft eine solche Kategorisierung dabei, eine Abgrenzung vorzunehmen, für welche Gefahren Versicherungsschutz über eine etwaige Cyberversicherung besteht und für welche nicht.

    Die Ursachen sind dabei die Risiken, während finanzielle bzw. nicht finanzielle Verluste die Wirkungen sind. Cyberrisiken werden demnach in zwei Hauptursachen eingeteilt. Auf der einen Seite sind die nicht kriminellen Ursachen und auf der anderen Seite die kriminellen Ursachen zu nennen. Beide Ursachen können dabei in drei Untergruppen unterteilt werden.

    Nicht kriminelle Ursachen

    Höhere Gewalt

    Häufig hat man bei dem Thema Cyberrisiko nur die kriminellen Ursachen vor Augen. Aber auch höhere Gewalt kann zu einem empfindlichen Datenverlust führen oder zumindest die Verfügbarkeit von Daten einschränken, indem Rechenzentren durch Naturkatastrophen wie beispielsweise Überschwemmungen oder Erdbeben zerstört werden. Ebenso sind Stromausfälle denkbar.

    Menschliches Versagen/Fehlverhalten

    Als Cyberrisiken sind auch unbeabsichtigtes und menschliches Fehlverhalten denkbar. Hierunter könnte das versehentliche Veröffentlichen von sensiblen Informationen fallen. Möglich sind eine falsche Adressierung, Wahl einer falschen Faxnummer oder das Hochladen sensibler Daten auf einen öffentlichen Bereich der Homepage.

    Technisches Versagen

    Auch Hardwaredefekte können zu einem herben Datenverlust führen. Neben einem Überhitzen von Rechnern sind Kurzschlüsse in Systemtechnik oder sogenannte Headcrashes von Festplatten denkbare Szenarien.

    Kriminelle Ursachen

    Hackerangriffe

    Hackerangriffe oder Cyberattacken sind in der Regel die Szenarien, die die Presse dominieren. Häufig wird von spektakulären Datendiebstählen auf große Firmen oder von weltweiten Angriffen mit sogenannten Kryptotrojanern berichtet. Opfer kann am Ende aber jeder werden. Ziele, Methoden und auch das Interesse sind vielfältig. Neben dem finanziellen Interesse können Hackerangriffe auch zur Spionage oder Sabotage eingesetzt werden. Mögliche Hackermethoden sind unter anderem: Social Engineering, Trojaner, DoS-Attacken oder Viren.

    Physischer Angriff

    Die Zielsetzung eines physischen Angriffs ist ähnlich dem eines Hacker­angriffs. Dabei wird nicht auf die Tools eines Hackerangriffs zurückgegriffen, sondern durch das physische Eindringen in Unternehmensgebäude das Ziel erreicht. Häufig sind es Mitarbeiter, die vertrauliche Informationen stehlen, da sie bereits den notwendigen Zugang zu den Daten besitzen.

    Erpressung

    Obwohl die Erpressung aufgrund der eingesetzten Methoden auch als Hacker­angriff gewertet werden könnte, ergibt eine Differenzierung Sinn. Erpressungsfälle durch Kryptotrojaner sind eines der häufigsten Schadenszenarien für kleinere und mittelständische Unternehmen. Außerdem sind auch Erpressungsfälle denkbar, bei denen sensible Daten gestohlen wurden und ein Lösegeld gefordert wird, damit sie nicht veröffentlicht oder weiterverkauft werden.
