Did some backtest and winning money by buying ung is really hard, basically it is designed to drop without spark risk.

Base on what I know: 1. VIX 2. Natural Gas 3. Oil then what are the rest?

any update?

Just did some simple math, just around 8 trading day this so called "AI" is around 0.8% worse than sp500 now. This is horrible! This AI thing would be annually 25% behind sp500 if you do the math!

This so called "AI" is still below its initial price while sp500 keeps making new high, is this AI having IQ 50 or what?

I don't know why it be hard for IB but it is an essential function for all local brokerage firms. None of the local brokerage firms are selling groups.

For almost all local brokerage firms in Hong Kong, clients can borrow 900% margin with very low interest rate for ipo.

With margin and without margin? What is the maximum ratio with margin?

This stock drops below its initial price today, so funny!

So far the performance is not good at all

Thx for sharing. The result would be very different if you rebalance base on diffferent timing or condition. The cost of ask bid rebalance can be high. The ib short interest rate is different everyday so almost impossible to simulate. I monitor all 3x oil etf and the borrow short cost change a...

1987 was around 140. Future would be like 70% of it which is around 100. This was within a day.

Lets say the short interest rate is 6% each while a lot of 3x etf rate is over 10%, your Portfolio2 annual cost is 18%. Portfolio1, 3 doesnt need to rebalance, so Portfolio2 would be a lot of ask/bid cost for each re balance in and out. So together is like 20%. It looks like you need 3 times the...

What is the average short inrerest rate of UPRO and SPXU? That would be an impact in backtest even if we assume there are always stocks available to short.

Short vix future would lose more than 1000%

When there is 1 day crash like 1987, future lost is instant without possible cut.

Contango is a big deal for some 3x etf too. 3x bull oil etf decay is an example. Yes vix is an extreme example. Sp500 3x etf is an "ok" option while it has benefit from a trend market but not chppy, while you can put 100% cash in it without taking the more than drop to zero risk.

Choppy decay is one thing, contango decay is worse.

So it is different from buying leveraged etf risk which is dropping to zero only for the worst case.
