> robinhood It's easy to have no fees if your customers can't make transactions. To be less snarky, I'd avoid them if you're trying to time the markets.

For those not in the loop: it's been impossible to make transactions on a number of platforms including Robinhood due to the overwhelmingly high load causing those platforms to fail. A lot of people were basically locked out from trading.

Or you know... Feb 29th, every four years.

Most people don't seem to understand that you don't pull all your retirement out at once, so the market going up or down doesn't really affect that

But whether you start your retirement at a time the market is down a lot or up a lot can make a surprisingly big difference on how long your money lasts, if you don't adjust your spending.

Doc, it hurts when I do this!

So...

Slightly unrelated, but why does the stock market close each night? If trading was open 24/7, we wouldn't have large spikes like this every morning. We'd only have them when certain news is announced.

Aside from people needing to sleep (back when computers didn't do our trading for us), there's also the matter of information flow: the reason quarterly earnings announcements happen after market close is to avoid giving slightly-faster people an edge.

If you could read and digest an earnings announcement faster than all your peers, you could make trades based on the new information before the price has moved.

While yes, some types of trading does rely on exploiting (usually small) information asymmetries, and "incorrect" pricing, it's much fairer if people have time to digest big required disclosures and all be able to get their orders in at (essentially) the same time: the opening bell the next day.

How long did it take Italy to go up three orders of magnitude in infection rate?

A bit less than 10x, an order of magnitude, every week. It's been really is very easy to see the future up until now. There's 9000 cases in Italy now; by the 16th of March, factoring in the containment measures, they could be 60-80k. About 10% need intensive care; there's probably 3000 IC beds available now. Very simple.

good news (sort of), Italian government did the math and shut down all of Italy.

Every medical expense, every food expense has the result of costing more of a percentage of your remaining funds. Many costs can’t be put off.

As an investor, if you believe the market is going to drop, there are various ways to profit from this. One of the easiest is buying ETFs that move inversely to certain market indexes (shorts them). For example, SH [0] is an ETF that moves inversely proportional to the S&P 500 index. So if the S&P 500 is down 2%, SH goes up 2%. More exciting are the leveraged ETFs that track double or triple the underlying index. SDS…

Inverse and short ETFs are terrible for medium to long term holdings. Because it resets each day. Here is an example of what this means: Consider a hypothetical index having a volatile week (like these days). The index was at 100 on day 1, dropped to 90 on day 2, recovered back to 100 on day 3, rose to 110 on day 4, and finished the week flat at 100. If you were invested in an ETF that tracks the index, you would nei…

You could also just buy some long put options or a long put spread. That doesn't seem to require being a pro and is a limited loss type of play.

All costs are on a spectrum of urgency. Food can be put off longer than water. A small plumbing problem can be put off longer than a large plumbing problem. A furnace problem can be put off longer if it's not cold. Replacing a car can be put off longer than fixing the brakes.

There is no such thing as having all your costs due immediately with equal urgency.

Unless you use robinhood which has no transactions fees.

Not just Robinhood. Charles Schwab and some others have moved this direction too.

Virtually everybody went to zero commissions, more or less.

Because extremely bull markets are a strong indicator of a bubble the laws should be equal to prevent bubble bubble bubbling.

Are they? The market reaches all time highs almost every year, so would you say that we spend most of our time in bubbles? It is actually expected that the market will typically go up, not down. Otherwise there would be no difference between investing and gambling.

It's a question of velocity - markets go up and down all the time... but speed breaks to prevent the market from going down to fast also need to prevent the reverse case - some sudden inexplicable and extreme price spiking.

Basically - we should protect against any really dramatic sudden changes as chances are that something is wrong.

In the last year the S&P grew ~22% prior to this recent drop, that's fine... and on a day swings in the low single digits might be fine. But if we woke up tomorrow and the S&P had recovered the pre-drop value and then grown 20% over that price - something weird is clearly going on and we should be worried.

They completely failed three different times in the past couple of weeks. The Feb 29th thing was a red herring.
