Much simpler,
I bought the IPO of TWLO. The company is the clear leader in its field (you can find articles on “Alternatives to Twilio” and the like, reading through its history, it is smart money funding the company, to ever greater and greater extent, and its value continuing to go up. $500 million in 2013, $1 billion in 2015 (based on private equity), it went to market underpriced due to IPO pessimism, and as I historically read about the company it has 400,000 registered developers, then a year later 550,000, the latest update is more than 900,000 registered developers, and growing.
The company is not profitable, but it continues to grow faster than expenses, and it does not have unlimited pricing power as there are 100s of other alternative providers (only a few even close to being a true substitute, and that would require rewriting business critical software to make the switch (no, it is not Microsoft or the like, we are talking APIs that can be re-written much quicker, and with lower switching costs, but the question is why would anyone go through the trouble just for a reasonable price premium. Simply they would not).
As for valuation, on tech terms it is still reasonably valued for a market leader, but given its IPO status, I have no idea where the stock will trade just on wide swings until it settles in.
I wrote a bit more about it on the New Stock idea board:http://discussion.fool.com/1069/twiliio-32291994.aspx
I am far too busy to follow the stock market like I use to. And frankly, I have found that buying and holding long-term is a more efficient way of investing rather than constant market monitoring or what not. Heck, if you owned a stock like ISRG, for example, crashed through the housing crisis, but had you just kept buying and not looking at it, you would not even have noticed.
More important to follow the investment thesis and business.
Twilio is in a remarkably rapid growing business, from Uber to IoT, and as the market leader, providing a better entire product (never gone down, not even when Amazon went down in 2011 (and they run on AWS)), the entire product, with better manuals, better customer service, a more complete whole product, with more developers, and more customers, Twilio will continue to gain a greater share of this growing pie than any other business in its field. That is just the math and networking effect.
Anyways, that is my spiel on it. Not market timing, but this is the first IPO I have ever bought into because of the above.
So I pretty much ignored Brexit, and have learned to live my life without constantly worrying or monitoring the market.
