A change in perspective

Which one of these investments would you want for the next 20 years? Mathematically you should be indifferent, but behaviorally you won’t be.

If you are aged 25-44, asset C will be cheap while you are still in the wealth accumulation stage of your life. This is why Josh Brown says millennials should be stoked for a market crash, and he is right. However, since we don’t know the future, it would be near impossible to stay with asset C while assets A and B also exist. Once again, the deciding factor is perspective.

This is why you should never forget the impact of your perspective, and the perspectives of others, when making investment decisions. You have to consider someone else’s investment umwelt before you make any important financial choices. When you see friends rushing into the hottest asset class, consider what their goals are. When you hear about a new stock tip from a broker, think about why they would be telling you that. When you feel the panic set in as everyone around you is selling, remind yourself of your long term financial plan.

Can the stock market predict the next recession?

By my calculations, the S&P 500 has had 20 bear markets (down 20% or worse) and 27 corrections (down 10% but less than 20%) since 1928. The average losses saw stocks fall 24% and lasted 228 days from peak-to-trough. Of those 47 double-digit sell-offs, 31 of them occurred outside of a recession and didn’t happen in the lead up to a recession. That means around 66% of the time, the market has experienced a double-digit drawdown with no recession as the main cause. Of those 31 which occurred outside of a recession, the losses were -18% over 154 days, on average.

We’ll have a recession at some point but odds are the stock market won’t tip us off ahead of time. In fact, most of the time people don’t even realize we’re in a recession until after it’s already begun. NBER typically gives the official word for a recession around the time they’re ending or already in the midst of a slowdown. The recession that began in March 2001 wasn’t officially called a recession by NBER until November 2001, the month it ended. The recession that began in the summer of 1990 wasn’t determined until the spring of 1991. And the recession that began in the summer of 1981 wasn’t called a recession until January of 1982.

The quality of quantity at Netflix

Calculating the customer acquisition cost for Netflix is easy — take the segmented marketing costs (handily provided by the company), and divide by the number of paid subscribers added.

The lifetime value of a Netflix subscriber. To work this out: 1. take the average revenue of a user in the quarter; 2. multiply it by the gross margin (to figure out how profitable a subscriber is), then
3. divide this figure by the churn rate — the proportion of customers which leave each quarter.

On to stage 2 of our calculation: the profitability per user. So that’s the numbers above, multiplied by the gross margin (revenues, minus the cost of providing the service).

Lower gross margins in the future due to higher content costs might effect the lifetime value assessment, but lets stick with existing numbers for now. So we’ve got the first two parts of our customer lifetime value calculation, leaving just the churn rate.

But that isn’t really what we’re after, what we want to know is the ratio between how much money a paid subscriber is worth — the lifetime value — and how much it costs Netflix to pull one in to its platform — the customer acquisition cost.

Tesla short seller warns of ‘massive’ supply-chain disruption

“We question the ability for Tesla to actually deliver on their promises to their customers when they’re on the brink of potentially a massive supply-chain disruption,” Quadir said in an interview on Bloomberg Television. “We see very little contingency planning, and we also see executives from the supply chain department departing in recent weeks and months.’’

Trupanion stock sinks after report of state probe

Part of the short thesis on Trupanion is based on the idea that vet activity may not comply with some state insurance regulations. It represents a bigger risk than consumer complaint investigations, which are commonplace for insurers. If regulatory challenges continue it could further dent investor sentiment about the shares.

Serverless computing’s innovative approach to software development

“By purchasing more cloud computing capacity then they really need – even as a deliberate strategy to safeguard against crashing key systems – or buying advanced reserves that they will never use, companies across all industries may be overspending on cloud services by an average of 42%, according to data compiled by Densify, a cloud optimization firm that works with big companies worldwide. That can translate into hundreds of thousands or even millions of lost dollars in IT budgets a year, depending on the size of cloud deployments, the firm said. Its estimates are based on input from 200 cloud-industry professionals and 70 global companies over the last year.”

Serverless is based on a very different resource management model. The biggest overhead is in the design of the application. Serverless applications are woven or composed from a collection of loosely coupled, lightweight modules or microservices. Each such module is only given resources when triggered by another application module or invoked by an external function. Serverless modules are expected to run for a relatively short time, and are generally limited in how long each invocation is allowed to run. Once the module finishes running, its resources are returned to the serverless platform and made available to other modules that need them. The modules are stateless, meaning that no information is carried over or remembered between invocations. Any information that needs to be persistent across invocations must be explicitly stored in a separate file or data base.

Given the special nature of serverless applications, developers no longer need to plan, allocate or provision module instances. Once a module is invoked, the serverless platform will figure out the resources it requires and automatically provision them. As other modules are invoked, the platform will automatically allocate the required resources, and take them away once they’ve finished running. Developers are only charged for the resources used during the time their modules actually run. If invoked infrequently, or if invocations are spiky, there’s no need to plan for and pay for just-in-case-resources.

Now apps can track you even after you uninstall them

Uninstall tracking exploits a core element of Apple Inc.’s and Google’s mobile operating systems: push notifications. Developers have always been able to use so-called silent push notifications to ping installed apps at regular intervals without alerting the user—to refresh an inbox or social media feed while the app is running in the background, for example. But if the app doesn’t ping the developer back, the app is logged as uninstalled, and the uninstall tracking tools add those changes to the file associated with the given mobile device’s unique advertising ID, details that make it easy to identify just who’s holding the phone and advertise the app to them wherever they go.
