The most important aspect of long-term investing is not watching daily stock price fluctuations, but having strong conviction in the assets you’ve invested in. Only through thorough research into a company’s business model, competitive advantages, financial health, and future growth potential can you remain calm during market volatility and avoid selling impulsively due to short-term news or emotions. Truly outstanding investors typically don’t profit from market sentiment; instead, they capture the value generated by a company’s long-term growth.
Once you have solid investment conviction, combining it with appropriate options strategies can further enhance overall portfolio efficiency. For example, while holding high-quality stocks for the long term, you can generate additional premium income by employing strategies such as selling covered calls or cash-secured puts. This approach creates ongoing cash flow while you wait for your holdings to appreciate. It’s not about chasing high risk, but rather about improving capital efficiency within a controlled risk framework to achieve long-term compounding growth. The core of investing has never been about speed—it’s about steadily and consistently building wealth over time.

The stock market has surged for two consecutive days—options trades made significant gains, and overall profits are substantial! Sometimes, when others are panicking, we should be greedy!

A friend of mine had been selling options for three years, specifically targeting deep out-of-the-money puts.
His rationale sounded really compelling at the time.
He’d sell a strike price far, far below the current market price—so far that it was almost certain to expire worthless, letting him pocket the premium immediately, since 'the underlying would never reach that level.'
For the first 30-plus months, he truly never lost money. His account equity curve was flat as a straight line, collecting premiums like rent every month.
Whenever we had drinks together, he loved saying one phrase:
“Selling options is way more stable than buying them—I’m basically making money while lying down.”
Back then, I actually envied him quite a bit.
And then came that one time.
One day, right before the market opened, negative news hit, and the underlying asset immediately gapped down.
The puts he sold were trading the previous day at strike prices he thought were 'impossible to reach,' but he woke up to find they had all become in-the-money.
What made it worse was that he had taken an exceptionally large position size.
Premiums were already thin, so he increased his position size to collect more premium.
When gamma kicked in, his account didn’t lose money gradually—it plummeted within minutes.
Three years’ worth of gains vanished in one go—and he ended up owing money on top of that.
Later, when he reviewed what happened, he kept talking to me about it for ages.
In reality, there were just a few key points he’d never taken seriously.
He was collecting only a tiny premium while bearing significant tail risk.
He was earning mere cents while betting his entire net worth.
Margin requirements seem harmless most of the time, but as soon as the market moves against you, they shoot up rapidly.
He thought it would take a long time to go from deep out-of-the-money to in-the-money—but when trouble hits, it can happen in just one day.
And then there are black swan events...

Although I believe in Micron Technology $Micron Technology (MU.US)$ Micron’s earnings will continue to be strong, but could the stock price pull back after the good news is fully priced in?
So I chose to sell the 850 put. Even if the stock pulls back to 850 or doesn’t rise, I can still pocket the full $20K by July 17. Better safe than sorry—this is the beauty of options! Make small profits step by step.
Tesla $Tesla (TSLA.US)$ Please step up your efforts—once earnings are announced at the beginning of July (from vehicle sales and energy storage), the stock will surge!

Last night $SpaceX (SPCX.US)$ The stock price dropped by 10 dollars, and many novice traders who had bought long calls or long puts were shocked to see that even put prices fell instead of rising. Everyone who initiated long calls or puts on the first day suffered losses, especially those holding long calls.
This is the most common pitfall for options beginners—implied volatility (IV) collapsing from elevated levels. In just two trading sessions, call option values evaporated by more than 70%, while puts also shrank in tandem. During early trading on the first day of options listing, the IV for the (0717) contract briefly soared to as high as 140%, resulting in absurdly inflated premiums.
I publicly warned at the time that IV would gradually decline—but it dropped far faster than I anticipated. By last night, IV had already plummeted back to around 98%.
In the world of options, simply buying long calls or long puts based on whether the underlying stock rises or falls is never enough. Implied volatility levels are equally critical—meaning that over the past two days, regardless of which side you were long, you got crushed by collapsing volatility on both fronts.
Those unfamiliar with options saw this as a golden opportunity to place leveraged long-call bets, while seasoned traders with real market experience immediately recognized it as a rare chance to act as option sellers.

$Broadcom (AVGO.US)$
📉 Broadcom just delivered a disappointing earnings report, sending its stock price sharply lower.
Here’s what happened: Broadcom reported its latest quarterly results, with revenue falling short of Wall Street expectations. More importantly, the company did not raise its sales forecast for AI chips this year—it kept the same guidance as before. The market had been expecting an upward revision due to the ongoing AI boom, and when that didn’t materialize—compounded by weaker-than-expected sales in its software segment (the part acquired through last year’s VMware deal)—investors started selling off shares.
To be honest, Broadcom is a fascinating company. On one hand, it sells AI chips to major clients (including $Alphabet-C (GOOG.US)$ 、 $Meta Platforms (META.US)$ these), while also operating an enterprise software business. Much of its massive stock price run-up over the past year has been fueled by the AI narrative. So when its AI business outlook offered 'no surprises,' the market reacted harshly—a concept known as 'expectation management.' This means stock prices reflect not how well a company performs in absolute terms, but whether it exceeds prior expectations. Broadcom’s results weren’t actually bad; they just failed to surpass sky-high investor expectations, which effectively counted as 'underperforming.'
A few things to watch: First, see if Broadcom’s management provides more details on AI orders in the coming days—such as new customers or contracts. Second, monitor how smoothly the VMware integration progresses and whether the software business can stabilize...
