According to the principle of value investing, people should pick stocks that appear to be trading for less than their book value. Which means buy when the stock price drops. There's another group of people who trade oppositely. They follow the market trend to buy and sell. The more a stock price has risen, the more they buy-in.
So which way is more "right"? The fact is, the reality is all grey areas. There are very few black and white answers. Don't rid yourself of ideology and narrowness. There are hundreds of ways to get rich if you stay open-minded. Different methods can be used in different scenarios.

A short squeeze can occur when a heavily shorted stock rises in value instead of falling. Short sellers could be looking to close out their position and can face a loss if they have to buy back the shares they initially borrowed at a higher price.
Here is a look at Fintel's top five short squeeze candidates for the week of Dec. 20.
$Petros Pharmaceuticals(PTPI.US)$ $iSpecimen(ISPC.US)$ $Reliance Global Group(RELI.US)$ $Vallon Pharmaceuticals(VLON.US)$ $Longeveron(LGVN.US)$
Mooers, let's look for the next $GameStop(GME.US)$or $AMC Entertainment(AMC.US)$.

$NIO Inc(NIO.US)$
Investors are getting more skeptical about putting their money into shares of China-based companies after SEC recently decided to tighten its grip on foreign companies listed in U.S. The SEC will accomplish this by implementing a law requiring companies to submit their accounts reports and other documentation for audit. If they fail to comply, they face the risk of being banned from trading on U.S. stock markets.
TCW Group forecast "most" U S  listed China stocks will be delist by 2024. Meanwhile, Nio's rivals are gaining a foothold in China, with XPeng catching the attention of Cathie Woods' attention.

$AMC Entertainment(AMC.US)$ my sell order set at 100k

Against the backdrop of the global covid-19 pandemic, 2021 has brought new challenges and opportunities to this year's trading. We responded with laughter and tears. This post compiles six stories that present a vivid picture of mooers' investing experiences. We sincerely hope that you will enjoy the stories!

"Never forget why you started, so your mission can be completed."
Every incredible adventure started with a baby step. When we look back to the very beginning of our trading journey, we ask ourselves why we got started in the first place? Realistically speaking, money is what we all are after, but what made us brave enough to take the first step? Here is one of the most satisfying answers.
"She Has Inspired Me" said by @HuatLady. His trading journey started with his 21 birthday gift – a $100 saving bank account book from his parents.
"I was touched because that was her virtuous desire for me to be independent, and to make effective decisions, not only for the trading field but throughout my life for a better Future."
Making profits is not the ultimate goal of investing. What you can learn in the process will get you further in life.
"The only way to overcome bad luck is working hard."
Novices deserve a bit of "beginner's luck." "Did I have beginner's luck when I first started trading?" @cowabangawas quite confident at first because of the money he made in the market. After that, there're setbacks, and there's luck again.
"As I trade along, the results are certainly compelling! I dare say I have one of the finest beginner's luck out there for my first few wins at the market provided trading returns in folds. It was truly an amazing experience given the confidence it spurs in you. But like what the market veterans would say 'the market giveth, the market taketh'..."
The truth is that luck is the combination of skills and opportunities. Many things that look like luck at first blush are part of a cycle. 
After investing for some time, many mooers might feel anxious and regretful. Some of us can't stop thinking about what we should've done when we were younger and what could've been achieved if we'd chosen differently. @aoimizushared his advice with the younger ones at "I hate finance ... but I'm here"
"I support young people who want to begin their investment journey early. As mentioned in a previous post (Gen Z and debt), I'd put aside my part-time job earnings as the capital for investments. I'd be more proactive in scanning the news and be updated on the overall environment. I'd become more curious about the companies that make the products I use, and study them more closely."
@小虎发大财wrote something about his words to himself if he can travel back in time at his post "I started my investment journey in 2017."
"I entered the market without any knowledge and purely by rumors, ended up suffering a loss.From there onwards, i started reading and watching video on youtube to educate myself, even till now hungry for knowledge. If I can return back time, i will tell myself to start off investment way earlier."
Regrets are common in trade because they occur both when you make a move or do absolutely nothing. How to deal with "regrets" when you want to start with "if only"? @Powerhouseresponded with "Really? Then you are not playing big enough!!"
"Investment is like this. You lost some here; you better wake up your idea to earn more somewhere else...Play within your means. That is how I consoled myself. Lose, never mind, just don't lose your mind and spirit. Miss the boat, try the other boat beside it!"
"The minute you appreciate what you have, joyfulness overcomes suffering."
2021 may not be the best in your life, but it couldn't be worse than 2020. Could it? We survived 2020, so when we start to appreciate what we have, 2021 could be a year full of joyfulness.
Do you agree with @Syueeat her post "Birds of a Feather, Flock Together!"?
"I believe in following the practice of gratitude, giving and sharing with the less fortunate. Not everyone is as lucky to have a roof over their heads, clothes to cover their bodies and food to fill their stomachs...Happiness keeps you sweet. Trials keep you strong. Sorrows keep you human. Failure keeps you humble. Success keeps you glowing. FAMILY keeps you GOING."
Moo community is committed to accompanying you throughout your trading journey and offering as much support as we can.
2021 might be the start of the trading journey for many mooers. We've seen many mooers saying that moomoo is what gets them started in trading. That is AWESOME!
@aoimizusaid in one of his posts, "There is a sense of camaraderie in the moomoo community, making me feel that this is not a lonely journey and I can always ask for help". This is exactly what moomoo wants to bring to all of you! We will always be there for you. Wish you all a very happy 2022 ahead!

moomoo annual ceremony is happening right now! Check it out here:  2021 in Review: Grow Together to the Moon!

Elon Musk has consistently supported $Dogecoin(DOGE.CC)$ , a meme-inspired cryptocurrency. He's invested in it, along with $Bitcoin(BTC.CC)$ and $Ethereum(ETH.CC)$ .
Musk sees dogecoin as the best cryptocurrency to transact with.
"Fundamentally, bitcoin is not a good substitute for transactional currency,"
Musk told Time Magazine after being named Time's 2021 Person of the Year.
"Even though it was created as a silly joke, dogecoin is better suited for transactions."
The price of Bitcoin soon took a dive after the interview.
Any thought on Musk's word? Will his opinion push you to buy/sell any related cryptocurrency?

This year's inflows into ETFs worldwide crossed the $1 trillion mark for the first time at the end of November, surpassing last year's total of $735.7 billion, according to Morningstar data. That wave of money, along with rising markets, pushed global ETF assets to nearly $9.5 trillion, more than double where the industry stood at the end of 2018.
Most of that money has gone into low-cost U.S. funds that track indexes run by Vanguard Group, $Blackrock(BLK.US)$ and $State Street(STT.US)$ which together control more than three-quarters of all U.S. ETF assets.
Technically they're not the same concept, but the $1 trillion landmarks still remind me of $Tesla(TSLA.US)$ hitting a $1 trillion market cap on Oct.25. It showed how influential the company is. 
Are you part of the one trillion? Would you tell me about the reason that you buy or not buy ETF?
