Self-reminding notes – part 1

By , September 15, 2011 4:11 am
  1. Ego is best shown through results
  2. Say I’ll be working for another 35 years. A hypothetically good track along 34 years has nothing to guarantee I’ll succeed in the 35th
  3. 35 years ~ 7 crises. I’m being optimistic
  4. Fail early
  5. Once you verify you have mastered one skill, quickly move on to learning new skills. Over-relying on a narrow set of strengths is self-destruct
  6. Among a few things that stain permanently, bad academic record is one, ethical misconduct is another
  7. When you think you are young enough to know "the new economy", look for evidence of gerontocracy
  8. When you win, there is no guarantee that you will be heard. But when you lose, your good stories at best look like lame excuses
  9. Appropriate duration to feel good about yourself after a feat is 2 miliseconds. Things move fast
  10. There are more polite people on earth than you think; I’m talking about compliments you have received
  11. The quasi-philosophical question "am I living or am I merely existing?" is pointless because existing in the market is already an extreme luck
  12. Only do devil’s advocate in small groups in controlled environments. 100% you are misunderstood then ill-interpreted otherwise.

Groupon: perfectly healthy, good cash flow, and well on the track

Groupon

  • Spent $263 million in 2010 and $208 million in Q1 2011 for marketing. Source: Groupon’s S-1 IPO Filing to SEC
  • Spent $203 million in 2010 for acquisitions
  • To generate net loss of $413 million in 2010 and $113 million in 2011

It can be profitable TODAY if it decides to

  1. Cut down marketing activities and rely on word-of-mouth
  2. Stop international expansion
  3. Net income would immediately be approximately $381 million, EPS $1.63

However, the scenario is purely hypothetical because international business is already larger than its NA revenue.

Additionally, cash flow looks good

  • $7 million free cash flow
  • $209 million in cash
  • $82 million in accounts receivable while trade credit is $519 million, or 6 times receivables

In terms of numbers, the current cash flow statement is perfectly healthy.

What’s worth the discussion is innovation in business model to generate supreme profits and create barriers to entry.

A technical note: my sensitivity analysis points out the factor that affects valuation the most is market performance.

Vietnamese netizens and consumers

By , September 2, 2011 7:48 am
  1. Vietnamese prefer anonymity and love to use pseudonym, like those from Japan and Korea
  2. 65% online communities are still built on (vbb) forums
  3. The physical distance between real connections is short people can meet one another in less than half an hour. Online?
  4. Majority of business is done through old school channels, not online
  5. Content-centric may be more welcome than relationship-centric. A lot of people don’t know what to do when they login social networks except for playing social games.
  6. Heavy herd behavior. All we need is a few influencers
  7. Monetizable segment: young urban female with disposable income from the rising middle-class. This matches with global Groupon customer profile
  8. Vietnamese love discounts. Source: Nielsen => Groupon
  9. Vietnamese love spending for F&B, entertainment, education, children. Source: Mastercard, Euromonitor

What I don’t like about HTC Desire Z

By , August 17, 2011 4:15 pm

htc desire z slide slider

  • The Z slider is tough to handle especially when one is in a hurry
  • The keyboard is too wide one can’t text with one hand
  • The phone is 12% heavier than a Blackberry Torch 9800

Overall, far from a phone for the texter.
