Yahoo finance conversations - OVV.TO stock research

April 30, 2020

Introduction

It is second day with over 10% gains for OVV.TO stock. I like to continue to work on research, and this time I came cross the conversations and then found articles to read related to OVV.TO.

Stock research

It is the first time I came cross yahoo finance stock conversations. I had problems with VAB.TO when the price went down 10% back in March. Now I knew where to find latest information.

WOW! This could partially explain the move in price in addition to general market sentiment. Follow the smart money: https://fintel.io/sob/us/ovv

How to time the market and come out good ideas at work?

Introduction

I spent time to review C# code and also .ASPX code, and I like to work on something simple. It is important for me to build good habit to review my own code, and follow good rules to write code.

Two day project

I spent two days to review the code I wrote, and then I make it simple, much more readable as well.

What is my favorite part of holding the full time job in April 2020?

What is most important - technology or basic needs?

April 30, 2020

Introduction

It is important to have no worries about basic need, specially in this coronavirus period, 53 years old. I felt so depressed on March 18 to take two sick days, since no one felt safe to stay in the office while outside news kept coming with bad news. I thought about my rent, rental property in Florida, all the cash I have, even though outstanding talent people in my age or my ex-classmates and friend retired at age 52, I am still worrying about food on table.

Technology or basic need

I work on software engineering job but I knew that it is not easy for me to be outstanding. There are so many bias formed through 2001 to 2010, even though I continuously worked hard but I still could not be confident to solve my housing problem in the city of Vancouver.

On March 19, 2020, I felt that it is a good solution to choose renting instead of owning. I do not have to worry about paying mortgage. I felt so good to have a full time job and also I can take less risk to adjust my life style, because I start to get used to be frugal, only shopping for necessity, and only keep minimum relationship, avoid relatives and stay isolated in Canada.

CSS short review - maintenance of website

Introduction

It is my fifth week to go back to work after two weeks break starting from March 19 to Arpil 1, and I like the life to work and got used to work full time very quickly. I need to learn somethings important about CSS, so that I can better manage the code base I have for my full time work. I need to take time to read good content about style, how to develop and maintain CSS code. It is better for me to master the basics since coronavirus is still here. A lot of people lose jobs every day, 30 million people in USA are unemployed and over 30 thousand jobs related to IT are gone as well.

CSS learning

I came cross the following reading materials, I enjoy reading and like to learn as well.

What to work on in my own choice - coding and design?

April 30, 2020

Introduction

It is serious lesson for me to learn as an investor. I did not know to sell high and buy low, since VAB.TO went up last month with gains $2000 dollars, and then in less than 12 business days, it went down with loss $1500 dollars. I did not learn the importance to sell high and buy low. From the lesson, I learn that I have to go back to simplify things at work, so that I can have more time to learn how to invest after the work. Technology eats my time, I have to think about Coronavirus, emergency, how I should support business without too much burden on myself as a software programmer. I am the only developer and then we like to continue to run business since we all have to live and do not like to get into debt.

Follow up

June 9, 2020

As a single person, I should ask myself what I should do. If I have a position in my portfolio which went up 100% in one month, I should invest all my cash in TFSA on this position at the very beginning. Or just after 20% up.

Do not just blog the gains, think about from different angles. It is hard for a single person to make sound decisions on this investment.

I should hire the professional ones in China, or contact friends I know working for bank; pay $60 dollars one hour to get some advice.

April 29 2020 over 10% gains of Oil stocks

My decision making - two thousand dollars purchase of oil stocks

My worries - Write down first

I like to write down my worries to prepare better mental health, and good psychology as an investor. I worried about so many things so that I could not invest over $26,000 dollars in bonds when I chose to rebalance SPX and VDU etf, and I only spent $2000 to build Canadian oil stocks and Air Canada stocks. I missed the opportunity to build wealth through the market bottom.

My worries

I do like to write down a list of things I worried, and next time I should write down those worries and learn to measure them. Do not allow those emotions affect my decision making in investment.

My stock analysis project - understanding terms

April 29, 2020

Introduction

It is so interesting to see my Canadian oil stocks go up 15% today, and I like to look into what I should learn from the investment.

My simple task

I need to review the analysis of four oil stocks from the video. I like to work on basic terms and then find out what to look into in order for me to evaluate what stock to invest.

4 Oil Stocks to Watch After The Oil Collapse

Here is the link.

I like to analyze how much it has room to go up for IMO.TO, and my holding went up 12%.

I just got more than 60% up from IMO.TO.

I like to share this comparison with my Chinese friends. IMO.TO is best one based on the analysis shown in the video by checking gross margin and operating margin.

April 29, 2020 10:02 PM
Take mass hit - strong balance sheet, they can stand when the oil price is low. Once the demand is coming back, the price will come back.

There is no interest to sell the price around $20.00 dollars.

Current Ratio

6:20/ 19:11
Current Ratio = Current asset/ current liability
Living on asset, 16,913 billion asset, 7.043 billion liability - COP (US)

XOM - have to sell asset and pay the liability

0.78 < 1 more risky - XOM
1.38 > 1 less risky - IMO

Operation margin

Average operation margin - 15, so IMO with 6% is very good.

Stocks looked at: 1. Exxon Mobil Corp NYSE: XOM 2. ConocoPhillips NYSE: COP 3. Imperial Oil Ltd TSE: IMO 4. Royal Dutch Shell Plc AMS: RDSA best value = Imperial safest = Conoco riskies = Exxon best dividend = Shell

Actionable Items

I need to figure out if IMO.TO has potential to go up 60% before Coronavirus sets down. If so, I should invest more on this stock.

Victoria TFSA - April 29, 2020

Sharesight

Actionable Items

Ask myself why the following oil stocks or pipeline have more than 10% increase in one day.

IMO.TO 12.67%
PPL.TO 10.27%
SU.TO 13.61%
CNQ.TO 16.27%
OVV.TO 14.92%

If I can understand the market, then I should put $41,000 dollar cash into those oil stocks, and then take the ride over 10% on April 29, 2020.

Trouble is opportunity. I like to remind myself to take more time to learn investment in this Coronavirus special days, months in 2020.

Support our startup interviewing.io

April 29, 2020

Introduction

It is tough time for every one and also for a startup company. I was busy last two years since every weekday 10:00 PM and weekend 10:00 PM for mock interview over 10 interviews, but right now the startup is in financial challenging time, I did not have mock interview last week. They are trying to focus on paid interviews.

Big thanks

I have those wonderful training as interviewer through last two years. I do believe that I developed so much strong muscle in terms of problem solving, algorithm research and coding crafting skills.

We have to think about how to make this small startup working again.

Uber discussing plans to lay off 20% of workers: Report

Here is the link.

80% revenue is lost. Total employee number is 27,000, so 20% layoff means 5400 people.

Diamond Offshore Drilling Inc - bankrupt

受价格战和新冠病毒肺炎疫情影响，油价暴跌之后，不少原油生产商都关闭了在墨西哥湾的钻井，导致该公司需求接近枯竭。

谈及破产原因时，戴蒙德海底钻探公司表示，在疫情爆发、沙特掀起价格战之后，海洋钻探行业急剧恶化。海上石油本就是生产成本最高的石油之一，当油价跌至不到30美元/桶时，该公司的处境就已经非常不利了。

今年开年以来，该公司股价已经累计下跌86.95%，至周五收盘时，股价处于1美元以下，为94美分。

公开信息显示，戴蒙德海上钻探公司登记资产约58亿美元，债务约26亿美元。近期，该公司没有按时支付债务利息。标普随即宣布将其债务评级下调至D，意味着该公司或将不会支付债务。

目前，该公司已正式宣布申请破产保护，成为继惠廷石油公司之后，第二家引发全球关注的申请破产保护油企。

公司的大股东是在纽交所上市的洛伊斯公司(Loews Corporation)，持股比例达到53%，公司旗下还有2500名员工，公司还留下了超过20亿美元的债务。

根据戴蒙德去年的财务报告，亏损几乎翻了一番至3.57亿美元，营收下降约1亿美元，至9.8亿美元。

4月中旬国际评级机构穆迪和标普就已经将其“降级”，穆迪称该公司重组债务的可能性很大，无论是通过与债权人达成庭外和解，还是通过破产程序。”标普对其评价“极有可能导致选择性违约或破产”。

北达科他州的页岩油生产商已经关闭了6000多口油井，每天减产约40.5万桶，约占该州总产量的30%。能源数据公司Enverus的数据显示，过去四周，在美国页岩油田运营的钻井平台数量下降了40%。

美国产油商还大幅削减了支出。根据能源咨询公司RystadEnergy的数据，该行业已经从今年约1300亿美元的计划支出中削减了约530亿美元。路透的数据显示，美国和欧洲五家最大的石油公司宣布平均削减23%的支出。Crowley和Adams-Heard的数据显示，上市公司已经削减了310多亿美元的钻井预算。

钻井平台关闭、企业削减预算导致许多石油工人失业。今年3月，美国石油和天然气行业削减了近5.1万个钻井和炼油岗位，降幅达9%。随着20日期货价格跌至负值，这一降幅可能进一步扩大。咨询公司BW ResearchPartnership的数据显示，如果把建设、钻井设备制造和船运等辅助工作包括在内，3月份石油和天然气行业的失业人数将再增加1.5万人。

大宗商品交易商托克集团（Trafigura Group）石油交易联席主管本·卢克克（Ben Luckock）表示:“上周一（美原油跌至负值）确实让人们意识到，石油生产需要放缓。”

The 2% Stop Loss rule (Trading risk management)

Here is the link.

Risk management is one of the most important aspects of trading. How does one manage risk so that a run of losing trades doesn't wipe you out? How does one deal with the emotional risk of not acting on a stop loss? How much money do you risk in any trade? The 2% rule is by far the best way of managing all of these potential problems and ensuring that your position size for every trade is exactly spot on so you don't have to worry about the money - just focus on the charts and the discipline.

5:37
2% rule

Only risk 2% of capital in any one trade

Protects you from a run of losing trades

50 trades goes to zero.

R - Run
Enter share at R10.00
Stop loss at R9.00
Risk per share = R1.00

2% = R1000 (R50k portfolio)
Therefore buy 1000 shares

18:48
No stop loss = GO BUST
Be comfortable with Rands at risk
Reduces stress when stop is hit
Determine stop loss level first
Use 2% rule
Thank work out quantity
Make sure Rands at risk doesn't scare

Risk Management Strategy For Trading

Here is the link.

Tell the story using my own words:

Given $10,000 capital to do day trading, set 2% as stop loss. Remember, 10 trades at most one day, if all of them fails, the total loss is 22%.

$200 for the loss of the trade.

Not a good trade

Profit per share 0.45
Stop loss per share 0.85

Keep ratio 2:1

Target price $10.50
Entry price $10.05
Stop loss price $9.20

Not a good trade - loss $0.85/ share to make $0.45/ share. It should be like 2 : 1, not 1 : 2.

Good trade

Target price $130.00, you like to sell around $12.80, then it will be good, since ratio will be around 2: 1

10 K walk and run - I want Vancouver back to normal

April 26, 2020

Introduction

It is my plan to take a day off to run 10 K and I chose to go to downtown. I had to take some photos and also take some break from my stock research, and make sure that I can get some good exercise and see the outside world. I did not go anywhere last week except working full time from Monday to Friday in the office, and I need to take some break and relax my mind. Covid-19 may not be so scary, the cure is bigger than the problem itself.

Vancouver - beautiful city

I decided to take my Google bag with me, so I can run if I need. I need to slow down and do not run in Burnaby lake or central park, since too much allergies. I need to make sure that I will not get red eye because of allergy season.

Summary of my walk and run

Skytrain - translink is losing money, and asked for government to help. The translink is in danger as business. Only a few people took the skytrain to downtown.
