As part of the BC Basic Income project, my team and I were tasked with trying to understand the system of income and social supports available to BC residents. We developed these visualizations which have proven very popular

1/

Get a cup of coffee.

In this thread, I'll help you work out how much money you need to retire.

2/

The goal is simple.

You want to accumulate a *large* portfolio of assets.

How large?

Well, you should be able to quit your job. And you and your family should be able to live comfortably for decades -- just off of the income generated by this portfolio.

3/

This is the crux of the "FIRE" movement.

FIRE stands for "Financially Independent, Retired Early".

The basic philosophy is: keep your spending needs low. Save a large portion of your income. Invest these savings. With luck, you'll be able to retire early.

4/

FIRE advocates have a rule they love to cite: the 4% rule.

The 4% rule says: your annual expenses in retirement should not exceed 4% of your portfolio.

You can use this rule to calculate how large a portfolio you need to accumulate before you can quit your job and retire.

5/

For example, suppose you and your family need $40K/year to live comfortably in retirement.

Then you need to accumulate a portfolio that's at least $1M.

Another way to say this is: your portfolio should be at least 25 times your annual expenses in retirement.

1/ Thread: $GOOG 4Q'20 Update

For the first time, GOOG segmented its cloud revenues/income separately, and overall revenue was >20% in 4Q which led to +7% after-hours reaction yesterday.

Here are my notes from earnings/press release.

2/ In the last quarter, here is the segment-wise growth:

Search +17.4%
YouTube ads +46.0%
Google Network Members +22.9%
Cloud +46.6%

Cloud more than doubled in the last two years.
Other bets losses $4.5 Bn in 2020 (vs $4.8 Bn in 2019)

3/ Operating margin in Q4 ~28%
FCF margin in Q4 ~30%

One of the big takeaways was the core business was even MORE profitable than most investors thought since cloud had -42.9% operating margin.

$GOOG's search business is a good comp for Fed in terms of "printing" money. JK.

4/ "you can track takeout and delivery orders when you book or order from Google Maps"

"More than 0.5 million channels livestreamed on YouTube for the first time in 2020"

"videos in our new Shorts player are receiving 3.5 billion daily views."

5/ Google Pay app is now used by >150 mn people in 30 countries.

Cloud backlog $30 Bn now (from $19 Bn in Q3)

# of Deals >$250 Mn became >3x

Waymo is providing hundreds of fully AV rides per week

Retail searches >3x YoY

Cloud operating losses flat YoY

Our intuitions often leads us astray. A good reminder: study counterintuitive math and economic results.

Here are 9 of them 🧵

The Birthday Paradox

In a room of 23 people, there's a >50% chance that 2 people share the same birthday.

This type of probabilistic thinking does *not* come naturally to many people.

The Coastline Paradox

Fractal geometry is also confounding:

The coastline of a landmass does not have a well-defined measurement. As the unit of measurement gets smaller (eg. from KMs to cm), the length increases without limit.

Winner's Curse

In an auction, the winning bid will usually exceed the intrinsic worth of an item leading to a significant overpay (and negative net profit for the winner).

Braess's Paradox

Removing an extra road can make everyone's commute time faster.

Why? The existence of a "fast" road leads to congestion because everyone uses it. If you remove the shortcut, traffic flows better.

Ten MF mistakes I recommend you avoid...

1. Too much love

A fund does well. You fall in love with the fund house. You have a large mid and small cap scheme from them. They all tank together! Diversify. And remember being good at one thing doesn’t make you good at the other.

2. One for all

Applying the same metrics to judge different asset classes. What matters to equity funds doesn’t matter to debt funds. Arb funds are fully hedged - the individual stocks don’t matter, they do in equities. Understand what matters for each asset class.

3. Perils of passive

Assuming all passive funds are good because they are cheap. There are terrible passive funds out there too. They track bad indices. Or they track good ones but have a lot of tracking error. Passive requires its own set of research.

4. Apples and kiwis 🍎 🥝

We have categories in MF but sadly all funds in a category are not comparable. Just because a website compares them doesn’t mean you should look beneath. BAF categories have funds that are static, dynamic bond funds have rolldowns. Just an example.
