關於 derivatives market ，我們在網路上蒐集到這些相關的討論、資訊與評價

昨天看到一份不錯的投資書單。這份書單是 Corey Hoffstein 分享的，他是量化投資機構 Newfound Research 的投資長，所以裡面分享蠻多跟量化有關的書。大部分都只有英文，我把有中文翻譯的整理出來了，疫情在家來慢慢消化。

做量化的人很多都是看跟交易相關的書，如果今天投資週期比較長的人可以先略過。一般投資那幾本我都還蠻推薦的，之前也推過幾次了。風險管理有很多本沒看過，如果有人看過哪本不錯的歡迎推一下。

🌻風險管理

跌了幾十趴的個股還要繼續抱下去嗎? 去年飆漲的SPAC, 今年還漲的回來嗎?(可以跟下篇一起看).

開始玩成長股後, 我學到最難的一堂課是風險控制. 每個人對風險控制的觀念不一樣, 這跟每個人的心理素質也有關係.

風險管理, 也就是"留得青山在, 不怕沒柴燒".

🌻There Are Too Many Defenseless(無防禦性的) Stocks
(可以的話, 我希望您可以好好讀一下這篇文章. 我希望能夠幫您守住些財富, 減少些損失, 甚至創造些獲利. "Too many", 也就代表了股票沒有稀有性)

The underwriters just created too many stocks. There's too many new companies, too many companies that help you with analytics(分析), too many that offer video, too many data collectors and too many real-time analysis, and too many cybersecurity companies. There's been too many new electric vehicle derivatives, too many cannabis (大麻) plays and way too many new fintechs(金融科技).

The effect? We are now facing a bewildering number of companies that simply do the same things and can't be differentiated (無差異性的) and, frankly, are too hard to understand unless you are deeply involved in the transfer of data from on your premises to the cloud(雲端).

Why does this matter?

Because these stocks are defenseless. They are defenseless against inflation (通膨) because so many of them sell at a multiple to sales and any company that trades as a multiple to sales (指的是以P/S為估值方式, 非傳統的P/E. 軟體公司主要是用P/S) will see its value erode more quickly than any other in this stock market because the company has to graduate from a multiple to sales to a multiple of earnings, or just keep losing money. So many new investors have not experienced real inflation where these kinds of stocks can't be given away.

They are defenseless against an economic boom. I have been reading through countless software as a whatever with a go to market strategy and a huge TAM (total addressable market, 指的是市場大小) to land and expand(指的是雲端公司的商業模式), and my eyes glaze over. Who needs a company with all of those buzzwords that's growing at 27% and losing money when I have plenty of high quality industrials that are growing at 27% and spewing cash to the point the biggest issue is how much should be put to growth versus rewarding shareholders.

They are defenseless against older companies with a balanced policy toward dividends and buybacks, so that supply is mopped up while demand is bolstered by a yield. The land and expanders don't have anything backing them up which makes them vulnerable to sudden shocks down as we have seen.

They are defenseless against insider selling. If capital gains rates are going up, these are the companies with the most vulnerable stocks because so many of the people in these new companies have stocks that are still up substantially from when they got stock so a company with a stock down 30%-40% is vulnerable from scads of insider selling, including secondaries I am now expecting with increasing frequency.

They are defenseless against SPACs. While there are many good SPACs there are too many SPACs with too much stock sloshing around. I keep thinking about that MP Materials (MP) secondary offering in late March, where entities controlled by CEO James Litinsky sold 4.6 million shares of his company in a deal priced at $35. Now it is a small percentage of his holdings and many others involved with the company sold small amounts, too. That's not the point. It's more of a statement: this stock traded at $50. You might have been inclined to buy on the pullback but you would have been massacred as the stock is now at $27. If you have a so-called successful SPAC its success might be measured by how much money you took out of it before its stock fell by 50%. There are hundreds of things and when you consider all of the warrants out there, you know this market is going to be overwhelmed with this stuff.

You aren't going to see these kinds of secondaries at Deere (DE) or Caterpillar (CAT) , that's for certain.

Now there are people out there willing to buy the incredibly almost stupidly risky stocks, people like Cathie Wood, who demonstrated her unflappable conviction to her method of buying stocks that worked when there's scarcity value but there's anything but that now.

Maybe she can take down tens of billions of dollars worth and save the day. I wouldn't count on it. I am sorry to question her stock picking, lord knows she's been amazing. But unless others copy her, we know the stocks she is buying resemble what's not working at all. Maybe someday, but not now.

I try to figure out what the end game for these stocks might be if the economy keeps heating up and inflation accelerates. There's simply not enough money from young people or ETFs based on high growth or Cathie Wood to keep these stocks higher, and there's too much opportunity for the insiders to do what MP did, something that crunched the stock even as it reported a quarter ahead of expectations, which meant something at one point but means absolutely nothing now. Nothing at all.

納指跌市元凶？！

//SoftBank is the “Nasdaq whale” that has bought billions of dollars’ worth of US equity derivatives in a move that stoked the fevered rally in big tech stocks before a sharp pullback on Thursday, according to people familiar with the matter.

The Japanese conglomerate has been snapping up options in tech stocks during the past month in huge amounts, contributing to the largest trading volumes in contracts linked to individual companies in at least 10 years, these people said. One banker described it as a “dangerous” bet.

The aggressive move into the options market marks a new chapter for the investment powerhouse, which in recent years has made huge bets on privately held technology start-ups through its $100bn Vision Fund. After the coronavirus market tumult hit those bets hard, the company established an asset management unit for public investments using capital contributed by its founder Masayoshi Son. //
