Co-CIO of Ambrus| (Focus: Volatility Trading / Tail risk hedging )| @penn guy ( These are my personal thoughts and not the opinions of Ambrus)

Follower of Christ ...New York
A little about me: I got started in the volatility trading business about 13 years ago, initially as the sole junior trader to Robert Kanter. From there, I went on to trade at several proprietary trading firms. After having the best year of my trading career, about six years ago, a few partners and I decided to start our own hedge fund. I like to think I’ve established myself as one of the top volatility traders in my space. Along the way, I’ve been fortunate to receive a few industry awards, recognition, and backings for what I’ve been able to accomplish throughout my career as a trader. My focus on this app is pretty simple: to have interesting discussions with other traders and PMs, help younger traders navigate their own journeys, and share some of the volatility trading philosophies and lessons that have served me well throughout my career.

I continue to see things like this regarding VIX, and I remain a bit surprised by the general lack of understanding here. The VIX is calculated using the bid-ask spreads of a 30-day weighted strip of SPX options, with the index updating every 15 seconds. Technically speaking, it is a measure of the market’s expectation of variance in the S&P 500. In layman’s terms, it is a generalized measure of implied volatility in the S&P 500. As of today, the S&P 500 is less than 1% away from its all-time highs with S&P realized vol at 11….. I am only stating objective facts. And it would be statistically more accurate to question why the VIX is so high given the actual factors. Sometimes we want markets to behave according to our view rather than acknowledging what is actually occurring.
THIS IS PROBABLY THE BIGGEST MYSTERY IN MARKETS RIGHT NOW. US long-term yields are hitting multi-decade highs. Oil is at $100. DXY is climbing back up. And yet VIX is at the yearly low, indicating there's absolutely no fear in the market. Either the investors think all these bad things are temporary, or they are about to experience the biggest shock in years.

More educational: When you buy a vix call you are buying a call that is linked to the spot changes of the futures contract. Not the actual index. The front month futures are at 17.50 right now….. So effectively you aren’t buying VIX at 14.50, you are paying for a risk premium of 6.50 vol points over realized. These are real factors to consider when you have discussions around the original post that I quoted.

This is a heuristic I learned early in my career that has saved me a good deal of money. Generally speaking: If you are short an asset and it experiences a stream of negative news that fails to push the asset lower, get out. If you are long an asset and it experiences a stream of positive news that fails to push the asset higher, get out.
Was that @Ksidiii who said or was it my old boss? I forget. But the saying goes: “If you have an asset that continues to eat bad news but doesn’t go down, there’s only one way for it to go young ace”

Over the last three months, there has been a repeatable and extremely sizable footprint in the /ES market that consistently comes in and drives equities lower. The flow has a very specific execution pattern. They pile into the order book, aggressively taking liquidity tick after tick through what looks like a compressed TWAP. The price impact is immediate, and the pressure tends to remain heavy throughout the moment they turn the program on. In some ways, it resembles forced or margin-related selling (waterfall like selling), despite the fact that it clearly isn’t. When they release from the orderbook, the market slightly bounces and then trades in a small range for the remaining part of the day. There’s other execution tendencies this end user has. I won’t list out all for obvious reasons but at this point I’m sure a lot of traders are seeing this. What makes it particularly interesting is trying to conceptualize what type of shop could be behind it. There are very few firms in the world with a balance sheet large enough to consistently trade this kind of size and execute in such an elementary manner. And no it’s not due to gamma or delta hedging. It doesn’t behave like a traditional equity derivatives dealer that would be hedging out delta/ gamma risk. The execution is less sophisticated, and the footprint tends to have a strong cross-asset relationship with moves in rates, which isn’t typically what you would expect from an equity derivatives market maker. It’s not a vol control fund, it’s not a pension or endowment. Which narrows the list down for those with a creative mind. These things end up making headlines weeks or months later. Whatever this flow is, it’s truly fascinating to watch this footprint reappear every few days with such force, consistency, and lack of care to hide their impact. I’m not sure I have ever seen a flow like this while markets are so close to all time highs.

I think as agents become increasingly sophisticated, it will become much easier to reverse engineer the footprints of specific market participants. Beyond the broader trading opportunities this creates, I think you’ll start to see firms with real, differentiated alpha become more reluctant to operate through SMA structures, despite the industry’s significant push toward SMAs over the last decade. The same dynamic could change how PMs approach pod platforms. If your trading activity can increasingly be analyzed and your IP inferred, PMs with genuine alpha will likely place a greater premium on longer-term agreements, stronger capital commitments, and greater protection around their strategies. The broader point is simple: transparency around proprietary IP will likely become more limited at precisely the same time that the tools available to uncover that IP are becoming dramatically more sophisticated.

RIP to Vance Harwood. Vance was an absolute wealth of knowledge in the VIX ETP market. Back in the days when quality information on volatility products wasn’t nearly as accessible, he consistently put out incredible research and thoughtful pieces, particularly for independent investors trying to understand the space. I’m not sure anyone came close to matching the consistency, depth, and overall breadth of knowledge he shared over the years. May God rest his soul and bless his family during this difficult time. A reminder to all of us that every day we get on this planet, is a gift. 🎁
Any clients or friends should be aware that Vance is currently unable to do any of his usual posting or work, since he is in the hospital with a serious- and still mysterious -condition. We are working to determine the diagnosis. Thank you for your understanding. - Heidi L. Nordberg (his wife)

Best Wall Street suits (besides Brioni lol)? I’m curious to hear what you guys have to say? I know this one is going to be quite mixed.
Wall Street Dress Lore: Today, finance bros are synonymous with the traditional firm-sponsored vest or Patagonia. It has become such a stereotype that mainstream media has basically labeled the look “cringe.” But the vest actually has some real Wall Street history behind it. When I was coming up in the business, as corny as it sounds, I desperately wanted a trading vest. Around 2011–2012, you started seeing more and more firms roll them out, and one thing was pretty apparent: traders wore the vests. Back then, it almost served as a delineator between someone who worked on a trading desk and someone who simply worked in finance. As a kid who was completely enamored with this side of the business, one of my early requests when joining certain firms was that a vest be included in my new hire package. But the vest didn’t originate as some random fashion statement. Go back to the open outcry era of the NYSE, CBOT and CME pits, and traders were famous for their brightly colored trading jackets. Over time, as trading moved away from the physical floors and onto screens, the industry’s uniform naturally evolved too. The suit and tie became less practical on trading desks, and fleece vests became part of the new uniform. But the firm that really helped turn the fleece vest into a modern trading floor staple was SAC. Steve Cohen was famously obsessive about the environment of his trading floor. The idea was to eliminate distractions and keep traders completely locked in. The floor was reportedly kept cold, phones used soft-touch keys to minimize noise, conversation was limited, and SAC branded fleece became part of the culture. And at the time, Cohen was one of the most influential figures in the hedge fund world. SAC alumni spread throughout the industry, other firms adopted pieces of that trading culture, and the vest began spreading across Wall Street. Eventually, it escaped the trading desk entirely. What once had a fairly specific association with traders became the unofficial uniform of finance: hedge funds, private equity, investment banking, wealth management, fintech, you name it. So yes, the finance vest is played out. It’s cliché. It has been memed into oblivion. But I still love it. And I still wear one.

I had an old boss who, on my very first day in the office, looked at me and said, “I think we have to get you some new suits.” At the time, I thought my H&M suit was perfectly fine 😂, so I was genuinely shocked that he said that. There used to be a tailor who would come to a hotel in NYC, and all the guys from the firm would rotate in and out of the hotel room getting fitted for new suits. Because the tailor serviced the entire firm, everyone would get them at a bulk discount. That was the first time in my life I experienced what it was like to wear an actual tailored suit.

The weekend news around the war is extremely bearish. Now, who knows what actually happens from here. Maybe some of the reporting is wrong. Maybe this turns into a big nothingburger and markets are up tomorrow. Maybe markets are down significantly. Maybe markets completely crash. Nobody really knows, I definitely do not. But that uncertainty, in itself, is one of the strongest arguments for doing tail risk hedging the right way. When you’re a trader, the CIO of a family office, an allocator at a pension fund, or simply an individual investor, you should be able to read news like this and have the mental clarity to say: “Okay. If it happens, it happens. And that’s okay.” Not because you’re indifferent to the outcome, but because you know there is a real backstop in place if everything hits the fan. Your portfolio, your business, your job, or your financial future isn’t suddenly dependent on the hope that a low-probability event doesn’t become reality. That mental clarity and peace has real value. It allows you to make better decisions. It gives you the ability to think opportunistically rather than emotionally. And it gives you greater conviction to remain disciplined in your broader investment process when everyone else is being forced to react. Philosophically, the approach we take at my firm is centered around actively trading volatility with a structural bias toward the tails. Other managers may approach the problem differently, and there will always be debate around implementation and structure. But those are ultimately details around the deeper philosophy. To me, one of the greatest benefits of tail risk hedging’s general philosophy is simple: when the world becomes uncertain, you don’t have to panic. And irrespective of the semantical details that is undeniable. You already planned for uncertainty and made peace with the outcome.

I think folks are missing the point of this post. This isn’t a bearish take. It’s the rational for tail hedging in a general sense.

Also, if I’m ever slow to respond to anyone’s texts, emails, DMs, Twitter replies, etc., please don’t take any offense to it 🙏🏾 Between team messages, peers in the industry, investors, my fiancée, godchildren, siblings, friends, training buddies, charity requests, my mother, relatives, and everything else in between, the list gets pretty long. Sometimes messages simply get lost in the shuffle, and I have to slowly work my way through the stack. It’s never intentional or personal. For context, this is what the message stack on my phone looks like right this second. Being completely human, it all becomes a bit challenging to juggle and things fall through the cracks.
Hey everyone, I’ve been getting some emails about this. I haven’t gotten back to anyone yet. My plan is to slowly work through this in the coming weeks/ months. This is a personal project of mine and unfortunately things have been super busy (trading/ running the business / etc). So if you haven’t heard from me, don’t think anything of it. Slowly but surely working through all of it🙏🏾 Enjoy the weekend!

I have a small group chat with other PMs at mid sized to large trading firms across the multis and other specialist shops. Just discussions about trading, anything fascinating going on industry wise, and the occasional cope and pity party when life and trading is hard (wives complaining about watching futures at 6pm on a Sunday lol). If anyone would like to join, shoot me a message.

This whole saga is a textbook lesson on why you don’t let the market sniff out your footprint or get into the inner workings of your strategy. Because once you do, you practically become a duck that has to fight a whole ecosystem in order to win.
