Basics on how to pick a stock

Partly based on the following article: Best Practices for New Investors:

 

Basic thigs to check in a stock:

  • P/E Ratio (Price/Earnings Ratio): Low is better than high. Benchmark is around 20 (Price to Earnings Ratio) P/E Ratio = MarketValuePerShare/EarningsPerShare & EPS = CompanyProfitPerYear/NumberOfShares. Therfore
    •                          StockPrice                    CompanyProfitPerYear
    • P/E Ratio = --------------------; EPS = --------------------------------------
    •                                EPS                              NumberOfShares
  • PEG Ratio (Price/Earnings-to-Growth Ratio): Determines a stock's value while also factoring in the company's expecte earnings growth providing a more complete picture than the P/E ratio.
    •                          P/E Ratio
    • PEG Ratio = -------------------
    •                          EPS Growth
    • E.g. PEG > 1 is overvalued; PEG < 1 is undervalued. e.g. PEG < 1 hast a lot of potention for growth
    • EarningsGrowthRate = (EPS this year/EPS last year -1)*100. e.g. -> ($2.09/$1.74 - 1)*100 = 20%
    • If P/E Ration = 22, then PEG Ratio = 22/20 = 1.1
  • If possible: Cash in its balance sheet; Income statement; Favorable net debt; Improving net margints
  • Tenbagger: Investment that appreciates to 10 times its initial purchase price.
  • Blue chip: Nationally recognized, well-established and financially sound company. Operate profitably in the face of adverse economic conditions.
  • Three types of goals:
    • Income-Oriented: Focus on low-growth firms in indusutries and sectors such as the utilities.
    • Capital perservation: Low-Risk tolerance, focus on stable blue-chip corporations.
    • Capital appreciation: Rise in the value of an asset based on a rise in market price.
  • Diversification
  • Keep your eyes open for emerging markets and new acquisitions etc.
  • Finding Companies:
  • Beta: A stock that swings more than the market over time has a beta above 1.0. If a stock moves less than the market, the stock's beta is less than 1.0. High-beta stocks are supposed to be riskier but provide a potential for higher returns; low-beta stocks pose less risk but also lower returns.
 


 

Openframeworks and Engineering

as mentioned on its website,

"openFrameworks is an open source toolkit to assist the creative process".

But it is more than that, it is a gate for the artists to be able to move more easily in the digital world. And it is also a gate for the engineers to use more aesthetics aids for representing their ideas, as well as for visualizing in a more easy way complex problems.

CAN-Bus in the Raspberry Pi

There are many devices in the industry, especially the ones used in land or air vehicles, that uses the CAN-BUS (Control Area Network) for the communication of sensors and actuators with a electronic control unit (ECU). On the other hand, development kits such as Raspberry Pi, allow the students to implement complex project with small budget. Therefore, I present here a tutorial for activating CAN features on a Raspberry Pi.
