How to speculate Snap IPO

By , February 7, 2017 3:36 am

Đầu năm bày nhau cách kiếm tiền

3. Hình trái: Thành tích này là công của IBD Goldman Sachs. Giá cổ phiếu ngày IPO cao nhất nghĩa là IB đã giúp khách hàng (David Ebersman) gom tiền về với mức định giá cao nhất có thể, tương đương most overpriced trong khoảng thời gian đó.

Vụ IPO của Facebook là một vụ cực kỳ thành công cho cổ đông hiện hữu.

4. Ai lỗ? Chủ yếu nhà đầu cơ và nhà đầu tư hốt ngay IPO.

Vì sao? Vì các broker của mấy nhà đầu cơ đó không đấu lại GS IBD.

5. Vì sao cổ phiếu Facebook overpriced ngay IPO?

  • Mark Zuckerberg không thèm doanh thu.
  • Các quỹ ép Mark phải IPO để exit. Ừa ép thì làm.
  • Mark đã cắm sẵn tài nguyên để quảng cáo là time on site. Cổ đông ép lợi nhuận thì vặn cái ad platform tí tẹo là doanh thu tăng đột biến, các mẹ ùn ùn mua vào, giá cổ phiếu muốn tăng thì tăng.

6. Twitter ra đời 2006. 2007, tôi bearish về Twitter. Vẫn là Goldman Sachs quá giỏi, đẩy được IPO một công ty vĩnh viễn không bao giờ có khả năng hoà vốn, xả hàng.

7. Cách đây 20 năm, Yahoo! sợ Microsoft nên không dám nhận là công ty công nghệ mà tự khai là công ty media. Snap làm media và tự khai là công ty bán máy ảnh.

8. Bearish pattern sẽ lặp lại với Snap. Nhưng Snap không thể làm được như Facebook nên sẽ thành một phiên bản premature hậu IPO bình thường chừng vài ngày rồi rớt.

Chim lợn phím hàng chỉ có vậy thôi.

9. Chơi liều thì Short Call với maturity ngắn nhất để finance margin for Shorting Stock.

Liều vậy thì khỏi mang tiền ra khỏi quê luôn.

11. IB sẽ lại kiếm tiền một độ thoát thân nữa. Nghe ngóng tình hình đu long theo khoảng 2 tuần trước khi tin ra là tối ưu.

Why Twitter never took off in Vietnam

By , December 23, 2011 11:38 am
  1. Vietnamese users like colorful, emotional, right-brain products. Twitter is analytical, left-brain. Right-brain: Tumblr, daily life, emotional messages, visual.
  2. Vietnamese users are unfamiliar with Follow, and have no incentive to learn the concept.
  3. Twitter is individualistic while Vietnamese in general are collectivistic.
  4. Vietnamese users haven’t had the need to follow influencers. In fact, many social influencers are not tech-savvy. Early Twitter adopters are geeks and online marketers who are not appealing to mass users.
  5. Vietnamese sentences are longer than those of English, on average.
  6. Early adopters started to use Twitter in 2007-2008 when smartphones were costly to mass users. When smartphones are much cheaper now, Vietnam Twitter is deserted. Also, it took too long for to roll out SMS service.
  7. Twitter offers no gamification.

Would Weibo clones do any better than the wave of dead Twitter clones in 2008? We’ll see.

Why I was banned from Twitter search and hashtag and how I resolved it

By , December 17, 2011 3:09 am

twitter account issue issues problem ban

Sometime in 2008 I was having issue with my Twitter account.

  1. A search of keyword "taitran" did not display my tweets
  2. My tweets were not displayed in hashtag aggregation, for example #barcampSaigon

I DM @support and received no response.

On 1 December 2011 I DM @support again and received a reply

Please file a support ticket so that our agents can check out your account. Mention that you’re not in search. Thanks!

I filed two support tickets. The cases are resolved after two weeks. Here is the response from Twitter:

Thanks for letting us know that your updates were not appearing in Twitter search results. In order to provide the best search experience for users, Twitter automatically filters search results for quality. To understand what might have caused your Tweets to jeopardize search quality, please review this page:

It looks like at some point a third-party website was posting duplicate Tweets to your account. We’ve now updated your account settings so that your Tweets will appear in the search results. Please note that it may take at least 24 hours for recent Tweets to be indexed, and due to the dynamic nature of Twitter’s search algorithm, you may not find every recent Tweet in Twitter search.

So the issues resulted from third-party apps messing with my account. I unauthorized all suspicious programs.

So now my Twitter account is back, full-pledged and healthy.

Hello searches and hashtags, so long!

How many Twitter clones in Vietnam have perished? What next?

By , December 3, 2011 6:41 am

Since 2008, the following


A veteran from the Twitter clone craze in 2008 is and they did implement the SMS mass messaging feature that I had hinted. Another one is also left is

In 2011, these new local micro-blogging products were launched:

  1. from VCCorp
  2. from VNG
  3. from VCCorp [slightly different in that it works on "add friend" mechanism instead of follow]

The wave of Weibo cloning will be observable in 2012.

Meanwhile, Tumblr is growing rapidly. Vietnamese users like right-brain products.

How social networking in Vietnam is different from other countries in the region

By , November 20, 2011 4:12 pm

10 years ago the first thing Vietnamese learn about communicating through the Internet is chatting. There were some services targeting Vietnam market before Yahoo! Messenger came to dominate all communication channels.

Yahoo! Messenger’s domination in Vietnam opened up the way for Yahoo! Mail and Yahoo! 360. In recent years, the email market share is largely chipped by Gmail. Yahoo! Messenger, while the top IM client, faces competition from Skype. Hotmail, Live Messenger and Gtalk are not widely popular in the country.

A growing trend is, however, that people start to learn about social networking and Facebook. Many sign up for the Internet to, first thing first, communicating via social networks. The same is happening in other South East Asian countries.

The social network battle in Vietnam in 2011 boils down to the dual-horse race between the two leaders Zing Me and Facebook. While Twitter and Plurk gain traction in other countries in the region, micro-blogging in Vietnam has never taken off. Even technology-enthusiasts use Facebook for live reporting (which Twitter is logically most suitable for) and viralling current events.

Why? My attempt to answer the question:

  1. Vietnamese language comes with diacritics thus requires a lot more than 140 characters to express a full sentence
  2. Vietnamese users are more familiar with “Add Friend” relationship than “Follow” mechanism
  3. Most importantly, Twitter doesn’t satisfy the gamification demand crazed by Vietnamese users. Vietnamese teenagers go on Zing Me mostly to play webgames. Many also go on Facebook sheerly for games rather than for connecting. Foursquare has received lots of attention probably thanks to the rewards and Mayor competition.

The next question pops into my mind: if gamification is so important, why hasn’t Plurk known in Vietnam while it is very popular in Taiwan and the Philippines? Again, my attempt

  1. Plurk hasn’t been covered by local media which is crucial in the growth of services. Facebook received local media coverage.
  2. Many influencers don’t know what Plurk is. As for me, I deactivated my Plurk account after collecting many medals.

Thanks @salsabeela and @kounila for sharing the information on social networking in your countries.


Tumblr is growing rapidly in Vietnam.

Ngoc Hieu has an explanation on the adaption Twitter: Vietnamese users like colors and emotions, neither of which Twitter offers.

Microblogging and social bookmarking 2011

By , October 8, 2011 3:43 pm
  • At its peak, Twitter had no more than 3000 users in Vietnam, the majority among whom are geeks. This is a rough estimation from many avid users. The number has dropped drastically since 2008.
  • Most Twitter clones in Vietnam failed. This year, I only see left. It eventually implemented SMS updates that I had hinted back in 2009.
  • 2 years after I deplurked, Plurk has been slowly gaining traction in Philippines and Taiwan. While information on the reasons Weibo dominates China is easy to find, analysis on Plurk is limited I still can’t answer why. A Taiwanese friend of mine, upon receiving my question, replied briefly “Personally I think the mechanism of Plurk is very close to Taiwanese ideology of mumbling”.
  • When Twitter clones don’t work, a new wave of products were hatched: VNG launched Zing Live, a proclaimed Weibo clone by its CEO. VCCorp launched and Pega, surprisingly, works on “add friend” rather than “follow” mechanism.
  • I would expect more Weibo clones to come.
  • Digg, reddit, Mixx, slashdot, furk are all dropping
  • Meanwhile, StumbleUpon is having a spike in traffic. What has it done right?

Evaluate the "Like" button on Friendfeed, Facebook, Twitter and Tumblr

By , April 26, 2009 7:52 pm

Friendfeed was the first major social media player to introduce “Like” option of a feed item. Soon this is available on Facebook. Twitter and Tumblr also provide similar feature. Looks like services with streams favor this concept.

The advantages is obvious to many users; they are now simply clicking on “Like” instead of writing comments. However, there are certain drawbacks of this feature.

Let’s consider the advantages and disadvantages on each aspect:

Advantages Disadvantages
To product owner Increase frequencies of interactions between users and feed items. Decrease lifetime of a feed item.
To users Quicker to comment. Move on to next item.

Historical data if “liked” items can be traced back.

The “Like” action is usually forgotten more quickly than actual comments with contents (Facebook case).
To community It is tempting to think that if the “Like” action spreads in the feed it would bring values to community.

However, frequency also needs to be considered as people tend to like more than re-share.

Psychologically, when someone hits “Like”, there is a feeling of “accomplishing a responsibility” for the item and no further action is taken. As a consequence, less re-share is made and the life cycle of the item ends sooner.


As the “Like” feature kills off re-share actions, it is appropriate for immediate status that has very short life. i.e. Personal status

It may devalue items which have values increased when shared such as a link or a thought.

At the core, it comes down to value of the feed item. If the item is worth and appropriate for sharing, it should be forwarded, not ended with a simple “Like”.

What do you think of my proposal?
