Many of you may have heard about Preferred Shares which are different to the Common Shares that investors generally deal with. What is a Preferred Share? Important points: Preferred Shares are similar to bonds, it's a loan to the company that gives you fixed % payments. However, unlike bonds, Preferred Shares can have no maturity dates and investors can be trapped for a long time. This also means that Preferred Shares don't necessarily go back to the par value after some time like bonds. Go through the Certificate of Designation carefully. Preferred shares are not as liquid (not as easy to exit). Most individual investors won't come across Preferred Shares. Payments to Preffered Shares can be delayed (for Cumulative Preferred Shares) or not paid at all (non-cumulative Preferred Shares). Non-cumulative Preferred Shares therefore don't make much sense for most investors. Preferred Shares are Callable , and the company can pay you back your money to e

Playing a musical instrument is a great way to give your brain a rigorous workout. Learning to read music, train your fingers, and coordinate between your eyes, hands, and ears activates numerous regions of the brain involved in memory, motor skills, hearing, timing, and more. As you continue practicing and advancing your musical skills, you'll be strengthening neural connections and even growing gray matter in areas like the auditory cortex. This can boost cognitive functions like focus, information processing, and working memory. Some research has found structural differences in the brains of musicians compared to non-musicians, especially in areas related to fine motor control and sound processing. Challenging your brain by learning piano, guitar, or even just basic melody and rhythm can keep your neural pathways active and adaptable. Plus, musical training from a young age can give developing brains a boost. Playing an instrument takes patience and discipline, but I find it imm

Even though most of the technologies demonstrated here are already achievable, to have them so seamlessly integrated into our daily lives still seem rather futuristic. Would this be 5-10 years from now?

The idea of implanted technology like RFID tags makes me squeamish and reminds me too much of dystopian fiction like the Hunger Games. However, many biohackers and transhumanists believe that implanted devices can genuinely improve our daily lives in practical ways. Though it may sound like science fiction, here are a few examples of how implanted tech could aid humans - look away now if you're faint of heart! Some active biohackers have implanted RFID chips under their skin, usually between the thumb and forefinger, that can be scanned to unlock doors, log into computers, share contact information, and more. While remembering passwords and keys can be a hassle, having an implanted chip may take convenience to the next level. Proponents argue that RFID implants aren't tracking devices, but simply access tools voluntarily chosen. Magnets implanted in fingertips provide a "sixth sense" of feeling magnetic and electromagnetic fields around you. Biohackers claim this allo

Volume= the number of shares that exchanged hands in a single day. Key Words from this lesson: Volume , Shares Outstanding . Note: an exceptaionally large volume traded in a single day may indicate that the stock price is at a peak or a low point.
