$SK Hynix(SKHY.US) Hynix's Korean shares fell 16% and US shares fell 9%, while Korean shares rose 2% and US shares rose 6%. What does this mean?

$Destiny Tech100(DXYZ.US) is overhyped. How can I short it?

$Unitedhealth(UNH.US) UNH should launch an insurance policy that pays out 1,000,000 if the UNH stock price falls below 200! I believe everyone would be very willing to buy it! 😂😂😂

$Unitedhealth(UNH.US)

With the first drumroll courage is roused, with the second it flags, with the third it's exhausted...

It has broken below the range again. Unless there's clear positive news for this stock, it's really in a very dangerous position.

$Unitedhealth(UNH.US) What are you dropping, kid? Do you have health insurance business in the Middle East? Not many Americans were killed or injured...

Look, getting impatient again...☝🤓

Has the customer service team been laid off? There used to be customer service available at any time, but now why do we have to wait in long queues? @Longbridge小喬

I would like to inquire, I have a vertical strategy options portfolio, and tomorrow is the expiration date. The system has alerted me that the margin requirement may increase. If there is insufficient margin or no stock holdings, it may lead to automatic (at the worst price) liquidation.

So, how much exactly will the margin requirement increase?

Now, because I don’t know how much the margin requirement will increase, and if it exceeds my available margin, the system will liquidate my position at the worst price as quickly as possible. Based on the current bid and actual value, this would turn a portfolio that was supposed to make a steady 78% profit into a 20% loss, a 100% swing. To prevent this uncertainty, I have to sacrifice the potential steady profit, giving up 78% profit and settling for a 32% profit by liquidating early! This is really regrettable.

Additionally, I believe the vertical strategy does not require an increase in margin. Because the vertical strategy involves buying one put and selling another put with the same expiration date, it ensures that there are enough underlying shares for delivery at expiration. In theory, no margin increase is needed. For example, I bought a UnitedHealth 285 put expiring tomorrow and sold a 277.5 put. If both are exercised, the sold 277.5 put would require someone to sell me 100 shares of UnitedHealth at 277.5. Although I don’t have enough funds to take delivery of these 100 shares, I can immediately exercise the 285 put to sell the shares at 285 to the person who sold me this option. Thus, delivery is ensured without increasing the margin. Other price scenarios also ensure delivery.

In summary, I need to know how much the margin requirement will increase for the vertical strategy as it nears expiration. Also, I have explained the unnecessary reasons for increasing the margin for the vertical strategy above. Thank you for your answer!

** I found Longbridge's margin requirements for option combinations to be very unreasonable. **

For example, the call vertical strategy option combination (I bought the 20270115 290 Call at 75.58 and sold the 20270115 400 Call at 30.78, with a maximum loss of 44.8), it does not calculate the margin for the option combination based on your maximum loss (USD 4,480), but roughly sets the margin to the price of the purchased Call (290 Call), and the margin requirement will increase as the value of this 290 Call increases.

For example, suppose UnitedHealth Group surges to 400 tomorrow, at which point the 290 Call will be worth USD 12,500 and the 400 Call will be worth USD 6,200. At this point, my option combination is worth USD 6,300. My maximum loss is still the cost of USD 4,480. However, the margin requirement at this time will increase from USD 7,558 to USD 12,500. And I may be forced to liquidate quickly because the margin is much lower than required. When liquidating, it may also be due to the large price difference between the buyer and seller of the option, and the system chooses the most "fire sale" method to liquidate in order to liquidate quickly, resulting in losses. But for this option strategy, I should make money when the stock price rises, and there is no increase in risk throughout the process, but I will be forced to liquidate due to unreasonable margin requirements.

$Unitedhealth(UNH.US) Sharing my experience holding UnitedHealth: At first glance, the account profit trend seems to closely follow UnitedHealth's performance, but in reality, it's as risky as shown in Figure 3😂

$CleanSpark(CLSK.US)Haha, both CLSK and MARA are trash hype stocks, always shorted when they surge. Shorting from 20 till now has been a feast. Real BTC investment means buying BTC, not these junk stocks 😆 Now at 10-12, it's almost bottomed out, time to exit.

$Unitedhealth(UNH.US) Holy moly, the trading volume is top 3, this is...

$Micron Tech(MU.US) has reached the resistance level, options have been sold, keeping a small amount of the underlying stock.

$Unitedhealth(UNH.US) I've seen many people strongly advocating for buying, with some even showing options expiring in about one or two months. Here are my personal views: the holding period for this stock won't be very short, so don't expect a significant rebound next week or even this month. Based on my observations of previous major downturns, it generally takes about three months from the start of the decline to see a substantial rebound. Conservatively speaking, it might take around six months to return to previous highs. The most recent decline and rebound cycle started with the CEO's death and ended with the stock's rise against the tariff storm. We are now at the beginning of the latest downturn. The sharp drop has mostly bottomed out, so you can start building your initial position, but don't go all in at once—keep some ammunition for adding at $360 or $340. Of course, this price assumption is based on no other major disruptions. If the U.S. starts implementing 'national healthcare' or similar policies that undermine UnitedHealth's foundation, that would be a different story. However, such events seem unlikely in the short term. Regarding the rebound target price and timing, I personally believe it could return to $500 within three months. If next month's earnings report is strong, it might continue upward, potentially reaching $550–$600 within six months. But if earnings are mediocre, meeting previously lowered expectations, the strong resistance around $500 could halt further gains, possibly keeping the stock oscillating between $450 and $520 until new positive catalysts emerge. In summary, don’t be impatient. Only consider starting a position if you’re prepared to hold for at least three to six months. Avoid the mindset of expecting a rebound within just one month. If buying options, always choose expirations at least six months out—otherwise, it’s pure gambling.

$AMD(AMD.US) recently broke through 115 and then pulled back to 100. If it doesn't fall below 100, you can open a long position. It's time to pay attention.
